Houston homeowners know what the rest of the country doesn't: your attic is fighting the Gulf of Mexico every single day. With annual humidity levels that routinely hover above 75 percent, summer heat indexes that push attic temperatures past 150 degrees, and a hurricane season that runs six months of the year, Houston attics face a combination of moisture, heat, and storm damage that few other cities can match. Mold growth, saturated insulation, and rodent infestations thrive in these conditions — and they compound quickly when left unaddressed. High-pitched rooflines common in newer Houston subdivisions create large attic volumes where moisture problems can develop undetected for months. Finding a company that understands these Gulf Coast realities is the difference between a fix that lasts and one that fails within a year.
There are 45 attic cleaning companies in Houston with an average rating of 4.5 stars.How We Chose These Companies
We evaluated attic cleaning and restoration companies serving the Houston metropolitan area based on several objective criteria. Google review ratings and review volume were the primary ranking factors — every company on this list holds a 5.0-star rating. We verified that each company specializes in attic-specific services rather than offering attic work as a side offering to general contracting. We also considered the range of services offered, with preference given to companies that address Houston's specific moisture and pest challenges. All five companies are currently active, licensed, and serving the greater Houston area.
The Top 5 Attic Cleaning Companies in Houston
1. AQE Attic
“The crew found a loose patch near the attic hatch and sealed it tight. Left everything spotless-solid work.”
— keira
AQE Attic leads our Houston rankings with a perfect 5.0-star rating backed by 153 reviews — the highest review volume of any attic-focused company in the Houston metro. They specialize in insulation removal, which is the foundational service most Houston attics need before any other work can begin. In a market where moisture-damaged insulation is one of the most common problems homeowners face, AQE Attic has built a reputation for thorough removal work that doesn't cut corners on the vacuuming and disposal process. Their high review count relative to competitors suggests consistent volume and a track record that spans years of Houston-area service. Homeowners repeatedly cite their professionalism and the completeness of their cleanup, which matters in a city where leftover contaminated insulation can quickly become a mold breeding ground.
2. The Restoration Attics
15255 Gulf Fwy #146A, Houston, TX 77034
“Absolutely phenomenal pest control company! All of their technicians are great, shoutout to Ivan and Edward for 10/10 customer service, and Isabella in their office for her insane flexibility and patience with appointment scheduling and follow ups! I will definitely be recommending to any of my residential or commercial clients in the area!”
— Shelby Allison
The Restoration Attics earns the number two spot with 129 five-star reviews and a service profile that directly addresses two of Houston's most pressing attic problems: rodent cleanup and full attic restoration. Roof rats are a persistent issue across the Houston metro, particularly in neighborhoods with mature live oaks and pecan trees that give rodents direct roofline access. The Restoration Attics handles the full scope of rodent damage — contaminated insulation removal, sanitization, decontamination, exclusion work to seal entry points, and complete re-insulation. Their attic restoration service goes beyond simple cleanup to return the attic to a functional, clean state. For Houston homeowners dealing with the aftermath of a rodent infestation, this end-to-end approach eliminates the need to coordinate multiple contractors.
3. First Defense Insulation
12 Greenway Plz Suite 1147, Houston, TX 77046
First Defense Insulation brings 83 five-star reviews and a focused insulation removal specialty to the Houston market. Their name signals their philosophy: insulation is the first line of defense in an attic, and when it fails, everything else follows. In Houston's climate, that philosophy carries real weight. Insulation that has absorbed moisture from a roof leak, condensation event, or tropical storm loses its thermal performance entirely and becomes a substrate for mold growth. First Defense Insulation's concentrated expertise in removal means they've developed efficient processes for extracting damaged material from Houston's characteristically large attic spaces. Their focused service model also means shorter scheduling timelines compared to full-service restoration companies that juggle multiple service types.

4. Chimney and Insulation Solutions
10101 Fondren Rd Suite 216, Houston, TX 77096
“Fantastic experience with Chimney and Insulation Solutions! They built an 8 ft chimney stack extension, installed a new crown and flashing, major repairs and finished everything off with a beautiful new gas logs set. The work was professional, clean, and clearly done with attention to detail. Everything looks amazing and will use for future projects. I have attached photos. I highly recommend them for quality craftsmanship and reliable 5 star service!”
— Thalia Gazis
Chimney and Insulation Solutions holds a 5.0-star rating across 61 reviews and offers a distinctive combination of chimney and insulation services that makes particular sense for Houston homes. Chimney penetrations are one of the most common entry points for both moisture and pests in residential attics, and a company that services both the chimney and the surrounding insulation can identify and resolve problems that a standalone insulation company might overlook. Their insulation removal work addresses the standard Houston scenario — old, degraded, or contaminated insulation that needs to come out before any improvement can happen — but their chimney expertise adds a diagnostic advantage when the moisture source or pest entry point traces back to the chimney area. For homeowners who suspect their attic problems originate near the chimney flue, this dual specialty is a meaningful differentiator.
5. Ultimate Radiant Barrier
Ultimate Radiant Barrier rounds out our top five with 24 five-star reviews and a specialization in insulation removal that feeds into their broader focus on radiant barrier solutions. Radiant barriers are more relevant in Houston than in almost any other U.S. market — the combination of intense solar radiation and prolonged summer heat makes radiant barrier installation one of the highest-ROI attic upgrades available to Houston homeowners. While their review count is lower than others on this list, a perfect 5.0-star rating across two dozen reviews indicates consistently excellent work with no dissatisfied customers. Their expertise in removing old insulation positions them well for homeowners planning a comprehensive attic upgrade that combines insulation replacement with radiant barrier installation for maximum energy savings.
What to Look For in a Houston Attic Cleaning Company
Houston's climate creates specific demands that not every attic company is equipped to handle. When evaluating providers, prioritize these factors.
Mold awareness and certification. Any company working in Houston attics should be able to identify mold growth and understand when remediation-level treatment is necessary versus simple cleaning. Look for companies whose technicians hold mold remediation certifications or who partner with certified remediators for severe cases. Houston's humidity means mold is never far away, and a company that doesn't take it seriously is a liability. Our attic mold remediation guide covers the full remediation process and what to expect.
Moisture management expertise. Insulation removal and replacement in Houston isn't just about R-value — it's about moisture control. The company should understand vapor barriers, attic ventilation requirements for humid climates, and how to assess whether existing ventilation is adequate to prevent condensation. Ask specifically how they handle moisture barriers in Houston attics and whether they test humidity levels before and after their work.
Hurricane preparedness awareness. Houston sits in an active hurricane zone, and storm damage to attics is a recurring reality. The best companies understand what happens to attics during and after major storms — wind-driven rain intrusion, blown-off ridge vents, and saturated insulation that needs immediate removal before mold establishes. Companies that offer emergency response or priority scheduling after storm events are worth noting. Our Texas attic cleaning guide covers additional regional considerations.

Frequently Asked Questions
Why is mold so common in Houston attics?
Houston's humid subtropical climate keeps relative humidity above 60 percent for much of the year, which is the threshold where mold growth becomes possible on organic materials. Attics amplify this problem because they trap warm, moist air — especially when ventilation is inadequate or when bathroom exhaust fans vent directly into the attic space rather than to the exterior. The combination of Houston's ambient humidity, frequent heavy rain events, and the temperature differential between air-conditioned living space and superheated attic space creates persistent condensation on roof sheathing and rafters. That condensation provides the moisture mold needs to establish and spread, often long before homeowners notice any visible signs.
Should I schedule attic work before or after hurricane season?
The ideal timing is before hurricane season, which runs from June through November. Scheduling insulation replacement, moisture barrier installation, or ventilation improvements in early spring gives your attic its best chance of surviving storm season intact. Properly installed insulation and sealed attic floors reduce the damage caused by wind-driven rain that enters through compromised roof areas. That said, if a storm has already damaged your attic, don't wait until the next off-season to address it. Saturated insulation and exposed wood sheathing will develop mold within 48 to 72 hours in Houston's humidity, so post-storm cleanup should happen as quickly as possible.
How does Houston's humidity affect insulation lifespan?
Houston's humidity accelerates insulation degradation compared to drier climates. Blown-in fiberglass insulation absorbs ambient moisture over time, which increases its weight and causes it to settle and compress faster — reducing both its R-value and coverage area. Cellulose insulation is even more susceptible to moisture absorption, and in Houston's climate, it can clump and lose structural integrity after major humidity events or minor roof leaks. Where insulation in a dry climate might maintain adequate performance for 15 to 20 years, Houston attic insulation often needs assessment at the 8-to-12-year mark. Regular inspection is the best defense — catching moisture-damaged insulation early prevents the cascading problems of mold growth, pest attraction, and energy loss that follow.
