Air Tight Insulation of Los Angeles

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.

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.

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.

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.
