Air Sealing in Los Angeles
Professional air sealing closes the gaps where conditioned air escapes and outside air, moisture, and pollutants enter. Lower your energy bills and improve indoor air quality in one step.
Professional air sealing in Los Angeles
Air sealing is one of the most cost-effective upgrades you can make to your Los Angeles attic. Gaps and cracks in your attic allow conditioned air to escape and outside air, moisture, dust, and pollutants to enter — driving up your energy bills and reducing indoor air quality.
Los Angeles Attic Cleanup uses professional diagnostic techniques to locate every air leak in your attic, then seals them with durable caulks, foams, and weatherstripping. The result is a tighter building envelope that keeps your home cooler in summer, warmer in winter, and cleaner year-round.
Air sealing is also the essential first step before installing fresh insulation. Without it, new insulation simply covers the leaks instead of stopping them. We pair air sealing with insulation removal and replacement for maximum comfort and efficiency.

Air Sealing FAQs
How much can air sealing lower my energy bills?
Many Los Angeles homeowners see a noticeable reduction in heating and cooling costs after air sealing, since conditioned air no longer escapes through attic gaps. Savings vary by home, but the improvement in comfort is immediate.
Should I air seal before adding insulation?
Yes. Air sealing should always come before new insulation. Insulation resists heat flow but does not stop air movement — sealing the leaks first ensures your insulation performs at its full rated value.
Does air sealing improve indoor air quality?
Absolutely. Sealing attic gaps blocks dust, pollen, insulation fibers, and outdoor pollutants from entering your living space, significantly improving indoor air quality.
How long does attic air sealing take?
Most attic air sealing projects are completed in a single day, depending on the size of your attic and the number of leaks. We'll give you an accurate timeline with your free estimate.
