Green Attic Insulation

We got estimates from 4 different contractors for attic insulation and fan installation. Green Attic was the most responsive, professional, priced fairly, and the work is top-notch!

Jaime and his crew not only did a fantastic job, they provided great service as well.

Virgilio and Albaro were great. Very friendly, considerate and knowledgeable.

Rigo and Wilfredo added insulation to exterior walls in two upstairs bedrooms. Both hard workers who explained the process and answered all of our concerns and questions. We were glad to have this crew in our home. Wilfredo said someone will call before coming tomorrow to do the finish sanding.

Romual and Jose it’s -10 and they were here on time. Hooked up power. Protected and covered all carpeting, walls doorways etc told me it’s going to be dusty with plaster walls and 6 hours later they are Cleaned up and gone. Total 420 sq ft blown in insulation into 4” dead air space in this 1910 house. Green attic has done my attic and now perimeter walls Highly recommend this team.

Crew did a nice job and were courteous. Denis and Marco, with the office, helped me through various quote changes which was very appreciated!

If I could give negative stars, I would on this company. Very unethical business practices. They quoted work at my home, which I reviewed and accepted as the price seemed fair. After the work had been started at my house the tried to DOUBLE the original quote, stating that they made a mistake on the square footage, along with other changes. I know there may be some small adjustments, but this was insane. I don't believe that this mistake should be my issue. They had already removed the insulation from my attic prior to adjusting this quote and threatening to walk away and not finish the work. I told them I did not want them back at my house. AVOID THIS SHADY COMPANY AT ALL COSTS.

Green Attic was incredibly busy at the end of 2025 due to the 12/31/2025 expiration of the Energy Efficient Home Improvement Credit. On short notice, their crews still managed to re-insulate our attic, cap the can lights on our top floor, install proper venting for our bathroom fans (that had been venting directly into our attic instead of outside), and pipe insulation into three drafty walls before the end of the year. There was was an equipment failure that caused a delay and kept work going until late in the evening on a Friday (which is our reason for four stars instead of five). This meant crews weren’t quite able to finish patching our drywall and perform a required blower test before they left. But they came back early in 2026 to finish the job. All in all, we were quite satisfied with the work and will be able to take advantage of the last year of the Energy Efficient Home Improvement federal tax credit before the poorly named "Big Beautiful Bill" ended it.

I got a couple different quotes for attic insulation and air sealing. Green Attic was by far the most professional and communicative company. Virgilio and Wilfrido, the insulation technicians, were fantastic. The entire experience from start to finish was a breeze.

Romulo and Jorge from Green Attic were amazing. They worked extremely hard all day installing our installation and provided the best possible service. They communicated well and went above and beyond. They additionally did a great job cleaning up at the end of the day. Couldn’t recommend them more!

I hired them for attic insulation and air sealing. Their quote was the best I got and they were thorough. The estimate was done by Frank, who was very thorough and helpful in identifying areas that needed to be finished - he asked about how many bathroom fans we had upstairs and I totally forgot about one that needed to be installed! The crew worked efficiently, answered my questions, and showed me the attic when it was done. I had done some research before about what kind of work needed to be done and it all looked great. If I had another attic, I'd hire them again!

I had green attic blow in insulation in my walls. Romulo and Selvin were very prompt. They were very professional and explained everything to me. When they finished they cleaned up all the mess. Well Done!

We loved working with this company! Very professional, and very nice folks working there. From the manager at the production office, to our installation crew Romulo and Selin. Everyone was awesome!

Alvaro and his crew were very respectful of our home they did a great job setting up completing the job cleaning up and handling all the obstacles they ran into Very pleased with Green Attic, attic insulation

Romulo and Mario did a great job in doing some minor blow in cellulose work in our home. The job was done cleanly (within reason, it's still construction). They were tidy and efficient. Time will tell if the work was effective, but given what I saw we should hopefully be much warmer. Strangely, looking forward to a very cold day.

Great work. Rigo and Selvin did a great job. They were on time and completed our attic insulation project very efficiently. It was a very messy job and done in very tight quarters. They laid tarps throughout the work area and cleaned up the space when done. Very satisfied with the whole project. Project was completed per our estimate and everything went very smoothly. Would definitely recommend Green Attic Insulation.

Romulo selvin and his partner Rogo was real professional, they came in and got the job done. The work I had done was blown in cellulose insulation, they explained everything that were to be done! Worked nonstop untill they finished.and cleaned up. I would recommend Green attic to any one with insulation problems ps. The next. Emanuel Mejia came to apply three coats of plaster and sanded it down. getting it ready for paint plus cleaned up. Excellent job. Thanks, green attic. .

DO NOT USE THIS COMPANY! I have had nothing but awful experiences with them. The initial guy that comes out is really nice but it’s obvious now that he would say anything to make a sale. We got new insulation in our attic less than a year ago as well getting our ceiling reinforced. Again, less than a year later and our ceiling is full of nail pops. Our ceiling looks worse now than it did before we dealt with this company. When we got our insulation installed we were told we wouldn’t have the wet and “sweating ceilings” anymore. That was also a lie. I have tried to contact them several times to make this issue right but they refuse to contact me back. Learn from my mistake and stay away from this company.

A truly awful experience. After a quote which literally took 5 minutes, $4500 for cellulose insulation. Texts to schedule were unresponsive. Finally called and confirmed a time. Took the day off work to be here to oversee. Crew was supposed to be here at 7am and at 7:10am I get a text saying: “due to a staffing shortage we need to reschedule your work. Can you provide a few possible date that works for you please.” No phone call nor apology. Contacted both the office and representative and still haven’t heard back 8 hours later and they were open. Beware working with this operation. I have lost a days works pay. Poor customer service to say the least. Good luck.

Alvaro and Jon did a great job re-insulating dense-pack cellulose insulation after water damage. The company got in quickly so I could proceed with the remaining work to make my house livable again.

Jose and crew were great! He clearly explained the process and all the work that would be done. They blew insulation into our attic to the proper level and cleaned up everything before they left. Overall, they did an excellent job.

I had my attic isulated and Romulo and Rigo were fantastic, I'd highly recommend Green Attic for any work you need done

Green Attic did a great job. I was very pleased with the work done and scheduling was done very quickly. Would recommend them for your insulation needs.

GreenAttic completed the work they outlined in their proposal, however two disappointments have led me to write this review: 1) lack of communication after the job was complete to answer follow-up questions about the work done, despite several promises that "the production team will get back to you" 2) I asked about the part on the proposal that said, "client is responsible for the ductwork to be sealed and taped properly before work starts." I was told, " Honestly, I've seen it happens once in all these years working for Green Attic insulation. I will not be too concerned about it." On install day, blown-in cellulose insulation infiltrated a duct, filling a bedroom with dusty cellulose loose-fill insulation unexpectedly. Huge mess. The installers wouldn't have even noticed it had I not discovered the mess and pointed it out. They cleaned it up as best they could, but this mess could have been avoided to begin with had my question been answered appropriately. A major snafu during the work followed by no communication or follow-up is a bad look.

Virgilio and Jose came to add some flooring and a pulldown ladder for 2 of our attics in Gilberts and did a phenomenal job. Not only did they do a terrific job, they are extremely respectful and hardworking. If I ever need anything done again, I would make sure it was them! Great prices and work from them and they represent Green Attic very well.

Workers arrived on time and were very thorough and knowledgeable. The issues I had were explained and options where given to help cost savings. Now I have reinforced ceilings, dry wall repairs , Attic ventilation, and more installation.

Omar and James did a great job. 5 stars for those dudes

I just had Green Attic insulate my attic space/ blown in insulation. They sent a crew ( Romulo + Jose), Both were very friendly + respectful of my home and were very informative of the process. Being a retired tradesmen, I appreciated Romulo + Jose's workmanship/ I was shown finished job and was completely satisfied. Highly recommend. Michael Rizzetto Schaumburg

Excellent experience. team kept me up to date, and the installation crew were courteous and did a great job

Prompt, clean, professional team led by Jose and his team. Fabulous job-highly recommend!

I was pleased with the work I recieved with the Company. James was my first point of contact. If it were not for him, I would not have proceeded with the scope of work. There seemed to be some confusion, and lack of communication on the front end (office). James was professional, knowledgeable, personable, and an excellent communicator. Also, the rest of the employees, Romulo, Johnny, and Jose are the best!

Romulo and his team were awesome, got our old insulation removed and replaced, all the cracks sealed, and fixed our bathroom exhaust vent in a single day! Super professional, cleaned up the place after (looks better than it did before they arrived), and kept a watchful eye on our kitties trying to escape. They even shovelled our driveway to get the truck in upon arrival (sorry about that!!). Thanks guys!

The crew was excellent, punctual and did a fantastic job. They made sure to protect the interior of our house.

Romulo and his team did a good job. They were quick and efficient. Took care to make sure the area was cleaned up after. Made sure the vents put in blended in nicely with the roof. Happy with their work.

I would highly recommend Green Attic. Great price and Rigoberto and Jhonny really did a great job on removing old insulation and installing new insulation. They also installed a new attic fan and bath exhaust fan. Very professional. Thank you!

Our house is drastically more comfortable after an air sealing and insulation project. They were also able to accommodate our request for a positive pressure blower door test (rather than negative), though it take a bit of back and forth to get that sorted out. They did very good work and I will definitely be reaching out again if we have any future insulation projects.

Romulo and crew did a great job! Very happy with results. Thanks Green Attic!

The crew was on time, polite and communicative. The work was done in a timely matter, and they cleaned up as expected. Great job, thanks

Romulo and Jose were excellent and the job was very well done. Will definitely recommend them.

We had four Green Attic workers involved over our three day project. The first day Alvaro & Jeff worked diligently at completing the mold remediation and insulation installation. They were polite, hard working and respectful of our home. The second day, Mario completed the initial mudding & sanding of the installation holes. Then on the third day, Mario and Sammy completed the final sanding and the opening of the soffit vents. These two men were also hard working and respectful of our property. The entire job went smoothly and comfortably.

I just had the roof of my garage spray foam insulation of 3 inches. The workers did a great job and were done in a timely fashion and thorough with their cleanup.

Romulo and Mario did a good job. Everything was clean up and we are satisfied. Installation of wall.

Green Attic installed blown in cellulose in our home. It was built in 1994 and our electric bills recently doubled due to data centers. We decided to upgrade the whole house with more thermal blanket. It’s safe and effective insulation. Doesn’t settle like others can. They do pressurize the insulation to force it into the wall. Make sure your drywall is secure as it could cause it to blow out. They can adjust pressure as needed to prevent this. The crew was on time both days and cleaned up well. This is the third time we have used them. Our next step is to remove all our siding install foam board on exposed sheeting. Next will be Tyvek house wrap, window sealing and new siding. Ty Green Attic

Romulo, did an amazing job with his 2 coworkers along side with him. He lead the attic insulation at my and did a clean work in a timely manner!

Romulo and team worked hard, were communicative, and left the work site clean. Great job - highly recommend

Attic Green was fabulous, Jorge and Rigo were great. Everything went smoothly and they cleaned everything up once they were done. Would highly recommend.

Romulo and his crew were great with the removal and installation of my attic insulation. They were efficient, thorough and left everything clean and in good shape when they left. The office was easy to work with for scheduling, making payments, etc. Would definitely use them again.

Romulo and Jose installed cellulose insulation into my full finished attic walls and crawl spaces. First, I would like to say they were very respectful of my space. I was not sure where they would have to place holes in my finished space to blow in the insulation, but once we agreed on where they should be placed, they were opened only to size necessary and sealed very professionally. Plastic was put up from ceiling to floor on all walls so that it would protect my valuables, furniture, and clothing from dirt and dust. I would recommend these two to come back into my home to do any type of work. They worked very hard. Took minimal breaks to ensure an on time completion. I am very pleased with the work that was done. The goal of this project is to lower my utility bill and to evenly regulate the temperature in the attic living space for a more comfortable living, doing the winter and the summer months in Chicago. I hope we were successful!

Romulo and his team did a wonderful job. Very professional. Everything was clean when they left. Frank our energy efficient expert was very knowledgeable, didn’t try to sell you anything that you didn’t want or need unlike some other companies

Romulo and his team were very kind and detailed in their work. They cleaned out well too. Excellent job.

Jeff and Rague were awesome. I recommend them for any removal or insulation job. Plus the the clean up after the job was done was great. Job well done💯

Romulo and Alvaro came to us to insulate our basement! They both did an excellent job and were both very detailed oriented. Would recommend!

I contracted with Green Attic Insulation for mold remediation and installation of a solar fan. The workers arrived on time and started work immediately. Jeff, Jose and Luis covered the floor (including the downstairs floor where the attic is accessed) and any items that could not be moved. They worked quickly and cleaned up afterward so I had nothing to do. Good value as well.

Romulo did a fantastic job. Great job filling tough insulation areas. Everything clean. Very friendly and thorough!

Romulo and crew did a great job. Place stayed dust free and earned their money.

Excellent work, flexible and respectful crew, patient in explaining and adjusting work as requested. Work of high quality, can't wait to try out my new insulation in wintertime! Highly recommended.

Insulation Romolo and Alvaro did great work I'm pleased

Romulo did a great job. Friendly, communicative, knowledgeable, professional and hard worker on our attic insulation project!

The team that came was great - super efficient. Was somewhat of a messy job getting rid and replacing some very old insulation but they did an amazing job with the cleanup.

Jamie did amazing job. Always do a clean job. Second time using them in different houses. Both times made my attics rodent free!

INCOMPETENT! DO NOT HIRE Frank sold us on their very professional service and completeness of their offering. We hired them to do a mold remediation, blown in insulation and attic fan installation on our Chicago townhome. First, before the job was even done, I get an email saying the job is done and to pay the invoice. A few hours later, another reminder to pay the invoice (guys are still in the house), when the guys want to leave PAY THE INVOICE. The next morning at 8AM, call, text and email about PAYING THE INVOICE. Word to the wise: DO NOT PAY THE INVOICE until the job is complete and inspected. Here are the issues after a day of work: 1.) Communication was a challenge. 2.) The workers asked to use the bathroom. I said of course, and thought they meant to actually USE the bathroom, like the toilet. Instead, the workers used our bathroom as their staging ground for heavy equipment. Our bathroom was completely remodeled 2 months ago and they didn't protect the floor, only using a garbage bag as their barrier. They scratched my brand new tile floor, in several spots because they simply did not use any type of protection under their equipment 3.) My brand new bath fan sounds like a jet engine. It was whisper quiet and when they added the venting to the outside it now sounds terrible. When I texted Frank the video he responded with "Jesus, that is unacceptable". 4.) When I contacted them about getting things corrected, CINDY from the PRODUCTION team told me someone would be by the following day between 1PM-5PM. I text her at 9AM that same day to confirm the appointment. Cindy confirmed. I waited around all day and she texts me at 4PM about scheduling someone to come out....um, our appointment is today I have been sitting here waiting all day. NO RESPONSE and NO ONE SHOWED UP 5.) Finally, I ask for SOMEONE who has authority and knows what they are doing to contact me. Someone named Dave texts, talks a big game about making sure things are right blah blah blah. We set an appointment for Today, Tuesday at 11AM. 11AM rolls around, no Dave. I text Dave, are you on your way? He texts back that he is 45 minutes away and made a mistake with the time. 6.) UPDATE: On a Saturday morning someone approaches my door. No one told me anyone was coming or who this person was. Language barrier again so I have this man get someone on the phone and it's Cindy. She acts IRRITATED AND DEFENSIVE that I am asking who the man standing at my door is and if he's qualified to fix my tile (he has too clean of tools to give anyone confidence this is his specialty) She has to get the owner on the phone before she would answer me 7.). I let him in and reluctantly let him attempt the repair. It looks ok at the time but once everything dries it's very clear it was repaired and doesn't look amazing. I should have trusted my gut and hired my own tile refinisher and not been ambushed by the surprise visit 8.) once complete, I call the owner and give him a run down of everything that happened so that he could understand from the customer perspective on all the ways his team dropped the ball ( I owned a small property management business and have appreciation for how hard managing field teams is and wanted to give him honest feedback about things that were wrong and could be remedied). How people were rude, blew off appointments, didn't follow up, could not communicate etc. I asked if he thought it was fair I pay the full balance of the invoice given the experience. He gave me a lot of explanations about how he needs to pay people, his price is low, and he acknowledged their failings and that he deserved the review but blah blah blah, bottom line he would take $100 off my invoice IF I WOULD REMOVE MY 1star REVIEW. Sorry, this is an insulting amount to offer after this whole ordeal and my integrity is worth more than $100. So, my review remains here for posterity Read reviews, check them out on the BBB...sadly, even if I needed a warranty repair I wouldn't even call them back out as they have lost my trust

I originally went with this company because of their good positive reviews. The key is how the installers actually do the work the crew led by.Romulo Was exceptional. Very conscientious and want the extra mile I would highly recommend this firm for anyone who needs attic insulation.

Very happy with the job from Green Attic. Everything looks great and they did a stellar cleanup afterwards as well. Thank you Romulo and Alvaro!

The technicians did an excellent job. They were very professional, friendly and polite. They worked nonstop and cleaned everything up. We would highly recommend them to others

Romulo and Reynaldo were terrific. It was clear they knew what they were doing. They showed up on time, were very clean, and went above and beyond by patching an intake vent where mildew was coming right into our living room. Great guys.

The team at Green Attic was fabulous. The guys remediated mold, put in new insulation, covered the can lights, and installed solar fans. They were so great to deal with and cleaned up everything. Would definitely recommend them!!!

Green Attic is the best. We have a bungalow that had no insulation on the 2nd floor. It was freezing in the winter and roasting in the summer. Romulo and Alvaro were skilled and efficient. Total professionals. They did a great job and cleaned up everything when they were done. Would highly recommend.

The Green Attic installation team (Rego and Omar) did a great job air sealing the attic floor, installing the baffles, applying the insulation and putting in the Attic Solar Fan. The also ventilated the upstairs bathroom fans with end caps on the roof. They showed many before and after photos so I could see the work that was done. The results were immediate with the upstairs as cool as the downstairs in an hour which was amazing! The whole process from the free estimate and consultation to the installation was flawless! I highly recommended Green Attic for any insulation or roofing project! Thanks! Brett

Jaime and Armando came and reinsulated my attic. They also installed a solar fan and external vent for bathroom fan. Very professional. Quick and made sure to clean up all the dust that escaped the plastic coverings they laid out. Would highly recommend.

Workmanship, communication, and genuine care are non-existent with this company. They have high google ratings but I would be skeptical of their authenticity. My experience started great with the sales person. That was it. After spending $7,500, I can’t even get a response to my issues from January 2025. This company quoted much more than competitors. I thought they would be honest and care about my project. You can see in the picture the area they addressed with insulation is 56 degrees while the bedroom was 68. Frank sold the project like it’s no big deal and they take care of this all the time. Julio came by with his crew and it seemed like he wasn’t briefed on the project details at all. Luckily I was home to point out what areas I paid for. In the end, it still didn’t matter. 66% of the areas are still cold and I can’t get an answer from anyone there. Seriously look at the negative reviews before hiring. Lots of similarities amongst them on Google and yelp to give you an idea of what you might deal with if you choose them. Glad my neighbor didn’t end up going with them. Update- after my 1 star review, the company called back and sent someone to look into the issues and add supplemental insulation. Next winter I will be able to see the results but hopefully this does the trick.

From the initial quote to the install, Green Attic, was accommodating and fast. Frank came out on May 20 and squeezed up into the attic space. Found black mold on the rafters from poor ventilation due to a broken fan. I appreciated his honesty and recommendations. Ten days later, Edgar and his crew (Omar and Rigoberto) arrived. They did a great job remediating the black mold in the attic, adding thick insulation, baffles and replacing the attic fan with a solar powered fan for continuous attic air exchange. When they finished, Edgar showed me the final air flow and his crew were very respectful of the property, cleaning and tidying up the work area. I would recommend Green Attic to anyone needing mold remidiation and insulation.

Green Attic was fantastic! Got a lot of work done very quickly and cleaned everything up as if they were never here. The attic looks fantastic and is mold free. Very satisfied with the job!

This review is for Leo that came over to fix a ceiling that the estimator put his foot through. He came over the same day and got the patch up and a first coat of mud. He was back first thing today for the final coat of mud. He is very professional and did a great job.

Jaime and Peralta came to insulate our living room and bedroom. They were punctual, super courteous, friendly and explained the process. I was impressed by their efficiency, care, and cleanliness. My family highly recommends the company and this awesome crew!

I got three quotes, all were close in price, but Green Attic included a more thorough approach, and more detail. (Like sealing around all conduits and pipes with fireproof sealant, something others said not necessary.). My project was for blown in insulation in the attic only. No foam, no fans, etc... pretty straightforward. The crew was on time, and did a good job protecting the house from damage or bits of insulation. (impossible to be perfect, but they were conscientious, and cleaned well afterward). They removed odd items and debris that were in the attic, ensuring that there would be minimal hidden hazards for any future attic worker. They even discovered an additional issue around the fireplace that they addressed without charging extra. It looked great when they were done. Absolutely get multiple quotes, but I had a very good experience with Green Attic.

We knew our attic insulation was outdated for many years, but couldn’t find a contractor to do the work. Green attic specializes in attics and they gave us everything we needed. They did all the work in one day. They cleaned up all their junk beautifully. Such hard-working guys I can’t say enough good things about green attic

Romulo and team spent two days insulating my attic areas. They were prompt, professional and very clean. Green Attic provided an insulation quality that is more efficient than the two other firms that I interviewed. When they noticed something that needed changing, they were very communicative on providing a solution. Time will tell this winter how well the insulation works, but I am optimistic.

Green Attic is beyond professional in the work they do and also how they comport themselves. I had never heard of them before and was looking for someone with high reviews. Not only for th quality of work, but professionalism, too. They have a great lead customer service person who gets the estimate and scope of work explained to you at the initial meeting. From there, their office staff and technicians handle the rest. They prepared me for what I should expect. They arrived in time. And they finished the job a day early. I couldn’t be happier. And my attic is night and day improved. R-Value increased. Aesthetically far more superior today than before they worked on it. I am very happy with the level of service.

communication, and genuine care are non-existent with this company. My experience started great with the sales person. Then Tim came and took photos for the attic and later I received the quote and I approved the work. They came and did 20% of the job and After that No communication. Every time I call they say. We will get back to you but they never call back. I can’t even get a response to my issues for more than a week. I don’t even know if they are coming back or I should hire a different company. Seriously look at the negative reviews before hiring. Very disappointing service

Such a pleasant experience working with Omar, Alvaro, and Romulo. They were courteous, respectful, and hardworking. I especially very much appreciated how well they cleaned up after themselves. I would recommend this team! Thank you GreenAttic.

IT'S BEEN A NIGHTMARE!!! Their main issue is their customer service is hit or miss. Also, there's bad communication between their staff and management, where I'd get messages about the same thing from different people and thru different forms of communication (texts, emails, phone calls). They did a big job on my house last year. Two attics and one with a lot of mold. One year later there's new leak stains, screws/nails distending out, and cracks in the ceiling. I reached out to Green Attic multiple times and they were MIA for several days. They finally responded a week later and sent their guy Julio, who acted kind of like a "fixer", but not the good kind. He was supposed to address our questions and concerns but instead was aggressive, loud, and confrontational. He claimed that we needed to do a big repair job on the cracks and leak or risk voiding our warranty, which all turned out to be nonsense. Then, after I posted my first negative review about them, their staff member named Dimitris began HARASSING me through excessive emails, texts, and phone calls to try and get me to remove/change it. I looked on Yelp and looks like they do this with customers who leave bad reviews. I got a 2nd and 3rd expert opinion (roofers and insulation specialist) to come and check things out, who clarified that it was a roof issue. It is odd to me that we received no guidance from green attic about the roof - before, during, or after their big job because they have a roofing department. Roofs and attics are obviously related, and both should be considered when getting major work done. We eventually got our questions answered and issues resolved but only after lots of extra time and stress. They came to work on a couple of odds and ends and when their guys arrived (2hrs later than the time window), they didn't have any guidance from their management on what they were supposed to do. It could have been handled much better and with less stress thru good customer service. Now, I've checked my attic since it's winter time and there's random large patches of frost which isn't good. I reached out to their customer service and they had Rodney call me to try to explain that this is normal? That's complete nonsense. Since then, they've gone silent. It's been a several months now.

Romulo, Alvaro, and Marcelo were fantastic during the 3 day project. They were thorough and walked me through everything they were doing so I understood. I can already feel the difference in rooms that otherwise we're cold just a few days ago. I can't recommend them enough.

Great service, highly recommend! We needed our attic inspected and insulated because it was sealed off when we moved in. The team gave a pretty accurate quote though they weren’t able to get into the attic to see everything. For the work, they were on-time, efficient, communicative, and did a great job cleaning up after, can hardly tell they were here. I will definitely call them again if we decide to do more insulation work.

Romulo did a wonderful job! We're very happy with the results! The team was very professional.

Green Attic did a great job. The installers were professional and left everything clean and neat when they finished . Walter and Jaime worked on the second day and did a great job. Edgar and Rigoberto did a fine job the first day .

Romuno and his team came on time and were very cordial and friendly. They discovered an issue with some electrical work while working on the insulation, which I was surprised and happy about, and were able to rectify the situation easily and at a great value, considering the timing of the project, etc. Romuno made it clear he want to ensure my satisfaction throughout the process. When finished, the job site was cleaned very well. I highly recommend this company and all its team members and hope to do more projects in the future with them!

These guys did a great job! Great price, quality service, and they offer several payment options and plans. I thought we bought a lemon of a house and the insulation and sealing job they did fixed all of our issues and were so thrilled! Highly recommend these guys. Plus they are local so it’s great supporting a chicago based company.

We have a somewhat unusual split level home that was built in 1968 that has three separate attic spaces. There was very little insulation left and many penetrations into the house. The upper level was unbearable in the summer and we imagined it would be very cold in the winter. We chose Green Attic because we felt they were more meticulous than other companies, providing the most detailed quote and explaining all aspects of air sealing and use of cellulose insulation. For anyone looking to insulate, please note that air sealing is just as important - you will not get much benefit from insulation if conditioned air from your home can be exchanged with your attic! Unfortunately, after the job started, they did find mold, but the extra cost to remediate was certainly worth it. After the job was completed, we were not surprised the temperature of the house improved, but what we were surprised at was the significant improvement in indoor air quality. Just see the attached before and after as an example of how bad our attic was vs. how good it now is.

Highly recommend Green Attic. Scheduled to have my attic re-insulated and Romulo and his crew did a fabulous job. The attic was in pretty bad shape prior to the work getting done and green attic made it look so good. The crew worked efficiently and got the job done in 2 days. I also asked Romulo to install a couple other things on my roof outside of the scheduled project and he very kindly and willingly did so without hesitation. Very pleased with how everything turned out. Thank you so much for a job well done! Before and after pics below.

Green Attic insulated my cemented crawl space under my home. The technician was Jaime Milton. He first disinfected the space. He then covered the ceiling with netting and then blew in cellulose dense material into the ceiling packed fully. Jaime was awesome. He and his associate arrived on time. They did the work in about 3 hours. They cleaned up afterwards. I would highly recommend them for your insulation needs.

Green Attic did a great job fixing all our attic issues (ventilation/insulation/mold) in our new house! Everyone we dealt with was friendly and professional from start to finish. Frank did a great job coming out and doing the estimate and Marian was very helpful at the office with scheduling/paperwork! The crew that came out to do the job was fantastic! Jaime, Jose Luis & Armando were very professional, showed me pictures as work was getting completed, answered all my questions and cleaned up everything when they were done. I would highly recommend Green Attic!

Green attic sent Alex and his crew to my house to insulate and install an exhaust fan...conditions in attic space well over 95 degrees and they didn't skip a beat! ThEY got up there and did exactly what Patrick (THE SALES PERSON) said they would do. They completed job in two days. Alex and his crew where very professional, efficient. They didn't waste time and didn't mind me askining questions. The explained thier process and procedures and where rt on schedule. I like that about Alex....he has great customer skills and pay attention to his work and how it may impact property and customer. The crew showed a ton of consideration for my home and my family. They made it seem like it was their home they where working on. I would hire Green attic, Alex, and his crew to work on my house any time. Thank you Patrick, Alex , the crew!. The experience ,workmanship was on points. Good fortune moving forward Green attick.

Green Attic takes customer service very serious. We have a 151 year old home and she needs extra Tlc. Of course surprises happen with old homes. Our air handler in the attic had an issue after an extensive insulation project. Green Attic sent out Julio and his team. They had the issue fixed within 24 hours. This company earned their 5 star review

Good Crew was very professional and their insulation work was good. Person quoting job was very good , quick and very responsive with questions Bad Really bad patch job by the crew. Even 'rough' path should have been a lot better than what they did. Site lead Jonathan was not very reliable with communication on the day of the job even though that was the expectation they set. No real follow up from company. Ideally they would be able to do some test to check improvement before and after insulation was added (even if there was a cost) The person quoting the job was not the same as crew doing the job. So I had to explain the work needed all over again which is not ideal, especially with language gaps.

Super happy with Green Attic. The whole process went smooth from day 1. They spray foamed the following: slab, crawl encapsulation, exterior wall, and flat roof. They also had the best pricing. Will use them again when I remodel more areas of the house.

The workers were perfect. Respectful of my property, my neighbors property, and requests. They listened attentively and got to work immediately with a great outcome - The end product of my attic work looked great! Most importantly, they took the same attention to detail with insulation to even post-clean up. HIGHLY recommended!

They did the attic insulation and wall insulation. They did a great job and were very professional and attention to detail. The crew was very efficient and cleaned up after it was all done. I will definitely recommend them to anybody needing insulation or any other work.

From my first meeting with Patrick to review the project and costs to his crew (Pomulo and crew) coming to carry out the work this was a great experience. We had maybe 3 inches of insulation at best and now we have nearly 20. We expect to see this improvement reflected in our heating and AC costs in the coming year and a more comfortable and consistent temperature especially upstairs where it would often be a challenge to cool down on really hot summer days. These folks were respectful of our home and did great work, I highly recommend them. On a price point, I'm a firm believer in "you get what you pay for". Green Attic was not the cheapest but also not the most expensive... rather right in line. We met them on a referral from a neighbor and I think with this project now complete, it was a great choice and excellent value! Thank you!

I contacted Green Attic for a quote on 10/20. Unlike the competitors, they were able to give a quote based on my provided dimensions, sight unseen. My project was garage attic insulation, so I can run my heat source in my finished garage without having to worry about creating a condensation environment, which could lead to roof rotting. The fact that they were willing to work with me on the quote over the phone was super refreshing. In fact, one of the competitors I called wanted to charge me $99 just to get an estimate! Of course, there was a disclaimer that the quote was subject to change based on final inspection, but nothing changed. To my surprise, after I accepted the quote electronically later that evening, James contacted me the very next morning (10/21) informing me he had a cancellation and had a crew at the ready if I was interested in having it done right away. I expressed some hesitancy because my garage was currently a mess as I have a project going on with my Nova. James assured me that they would be more than willing to clear a path and take good care to make sure my car was fully covered and protected. Not only did they keep their word, but James even texted me photos to put my mind at ease (which I've shared here). I now have proper baffling for venting and 18" of loose fill insulation to get me to a value of R-60. Their guys were in and out in about 4 hours and there was literally not a trace of their being there. James came by the next morning to collect payment. Simply put, this transaction could not have been any easier than it was. In a world of it being increasingly difficult to get contractors to show up, this was such a refreshing experience. Thanks for a job well done, Green Attic! James and crew knocked this one out of the park for me.

I purchased the Energy Audit and I couldn't be happier with the results. After consulting with several different companies about my home's thermal efficiency/heat loss issues, I wasn't satisfied at all. It seems that almost any contractor I talked to just wanted to recommend their own solution, rather than help me accurately diagnose the issues. One company said I needed to spray foam the rim joists (they're a spray foam co.), another said I need to blow cellulose into the wall cavities from the outside of the house (just happens to be their specialty), another individual contractor told me to frame one specific room and use fiberglass batting (I guess that's just what he knows best). You get what you pay for and no free quote is free when all you ever get is a recommendation to do what the company likes to do best. So I decided to pay for an energy audit in an attempt to get an unbiased opinion of the real issues so I could make the best decision and hopefully not waste money doing this piecemeal without a holistic understanding or a good/better/solution. Tim from Green Attic Insulation was incredibly thorough and interactive, showing me every cold spot in the house with a thermal camera, then setup a blower door and showed me again how air was getting in and causing most of the issues. We talked about the basement, the attic, the walls and how his experience with other homes in the area informed his understanding of the issues in my home. That's exactly what you should look for in a contractor, someone who is willing to take a close look, explain the science, give recommendations without getting the work, and follow-up with all results and photos, regardless of further work. You have to pay for that, you can't just hope that you get it from a free quote. Best part: Tim gave me pointers on how to address many of the issues myself since I'm comfortable doing some things myself. I also got quotes for further work if I wanted to take it to the next level after I've addressed the quick wins on my own, and those quotes were very reasonable and competitive.
