Air Tight Insulation of Los Angeles

Air Tight Insulation of Los Angeles made my home feel brand new. No more drafts and perfect temperature throughout.

We had ice dams last winter that caused ceiling stains. Air Tight diagnosed poor insulation and ventilation, not roofing. They added R-44, installed baffles, and balanced the airflow. No ice dams this winter and the attic is actually cooler in summer.

Another company quoted me $8,000 for spray foam. Air Tight said it was overkill and recommended dense-pack cellulose with air sealing and radiant barrier for under $3,500. My August cooling costs dropped 31%. No high pressure, just honest advice.

I live near the 405 in Westwood and freeway noise used to bleed through my ceiling at night. Since Air Tight sealed every gap and added dense cellulose, the traffic hum is maybe half as loud. The crew was punctual, quiet, and helped me get $400 back from LADWP.

We have a mid-century in the Hollywood Hills with an 18-inch attic most companies won't touch. Air Tight sent a crew that actually fit. They spent a full day sealing from a crawl position and got coverage into areas I assumed would always be empty. Our master bedroom went from freezing to comfortable.

My grandmother lives alone in Silver Lake and her AC ran constantly just to hit 80 degrees. Air Tight worked around her furniture, spoke to her in Spanish, and sealed her unweatherstripped attic hatch. Her July bill dropped from $340 to $210.

I was skeptical about paying for air sealing until the estimator explained it's like wearing a heavy jacket with the zipper undone. They sealed every plumbing stack and wire penetration before adding insulation. The draft near my fireplace in Pasadena completely disappeared. My 1952 house has never felt this solid.

I inspect properties for a real estate firm and Air Tight is the only company I consistently see doing proper air sealing. Most blow insulation over gaps. Air Tight seals first. I recommended them for a fixer in Eagle Rock and the inspection came back perfect.

I manage an eight-unit building in Koreatown with old knob and tube wiring that scared off other contractors. Air Tight coordinated with my electrician, scheduled around the rewiring, and still came in under budget. My gas bill dropped 22% and tenants finally stopped complaining about cold floors.

My dust allergies were aggravated by decades of nasty old attic insulation. Air Tight removed it all, vacuumed, sanitized, and installed cellulose treated with boric acid. Less dust, less sneezing, and my guest bedroom is actually comfortable now. Worth every penny.

I called Air Tight Insulation of Los Angeles after my summer electric bill hit $480. The estimator spent an hour in my Sherman Oaks attic crawling to the eaves and found open gaps around my chimney and recessed lights. They sealed everything before blowing in new cellulose. My upstairs bedrooms dropped from 86 to 78 the next day. No shortcuts, just solid work.

If you have an older L.A. home, you need to call these experts. We struggled with dust and uneven temperatures for years. Air Tight Insulation identified that our attic and crawlspace were essentially open to the outside, sucking conditioned air out. Their air sealing and insulation work has been transformative. The house is cleaner, quieter, and the temperature is uniform from room to room. The crew was punctual, professional, and clearly masters of their craft. Highly, highly recommend.

The professionalism and attention to detail were exceptional from start to finish. After a disappointing experience with another company, Air Tight Insulation provided a clear, data-driven assessment of our home's issues. They didn't just sell insulation; they sold a solution. The crew worked diligently, sealing every gap and penetration they could find before adding new insulation. The difference in comfort and the reduction in outside noise is profound. A truly top-tier service in the LA area.

Outstanding expertise and execution. I've worked with insulation companies before, but none with this level of precision. Air Tight Insulation of Los Angeles focuses on the critical first step: stopping air movement. Their consultation was an education in building science. The installation team was skilled, respectful of our property, and left everything spotless. Our HVAC system now runs efficiently, and our energy bills have dropped significantly. This is not just an insulation company; it's a home performance specialist.

I am beyond impressed. This company solved a problem that others couldn't even diagnose. We had a room that was always uncomfortable, and they traced it to major air leaks in the rim joist and ductwork. Their sealing work was comprehensive and precise. The crew was knowledgeable, answered all our questions, and took great pride in their work. The room is now perfectly comfortable. Air Tight Insulation doesn't just do a job; they fix the root cause. Outstanding service.

This company absolutely lives up to its name. We had a historic home in Los Angeles with major drafts and temperature swings. Air Tight Insulation performed a comprehensive energy audit with a blower door test to pinpoint every leak. The sealing work they did was unbelievably meticulous—around windows, doors, outlets, and in the attic. The crew was professional and clean. The result is a home that feels solid, quiet, and consistently comfortable. Their scientific approach is worth every penny.

Choosing Air Tight Insulation was one of the best decisions for our home's efficiency. Their process was thorough: diagnostic testing, a detailed proposal, and flawless execution. The team was efficient, courteous, and maintained a clean worksite. The air sealing they performed has not only improved comfort but also seems to have improved our indoor air quality by reducing dust infiltration. The value of their work is evident every single day in our consistent and comfortable living environment.

From the initial contact to the final walkthrough, the experience was first-class. The quote was detailed and transparent. The crew that performed the work was a well-coordinated team of experts. They methodically sealed our attic, addressing complex areas around lights and ducts that are often overlooked. The before-and-after difference is not subtle; our home now behaves like a modern, efficient building. For anyone in Los Angeles serious about home performance and energy savings, this is the company to call.
