Expert crawl space insulation in San Anselmo, CA. Licensed spray foam contractors with manufacturer-backed warranties and free inspections.
If your San Anselmo home has cold floors, musty odors, or moisture issues in the crawl space, the solution is closed-cell spray foam applied to the walls and rim joists. Lapolla Industries crews create a sealed, conditioned crawl space that eliminates these problems permanently.
When San Anselmo, CA property owners need crawl space insulation, they turn to Lapolla Industries for the same reason thousands of customers nationwide do: we solve the root problem, not just the symptom. Our diagnostic approach uses infrared scanning, moisture mapping, and visual inspection to ensure the solution we recommend is the one your building actually needs.
With over two decades of spray foam experience, our San Anselmo crews have seen every crawl space insulation scenario California weather can create. We use that experience to select the right foam type, coating system, and application method for your specific property — delivering crawl space insulation results that hold up to San Anselmo conditions year after year.
From inspection to completion, here is how we deliver professional crawl space insulation results.
Every project begins with a thorough inspection of your property. We evaluate the existing condition, identify problem areas, and use infrared moisture scanning when needed to reveal hidden issues. You receive a detailed report with photos and honest recommendations.
Our preparation process includes substrate inspection, cleaning, moisture testing, and priming. We mask all areas not receiving foam, set up containment where needed, and verify that temperature and humidity conditions are within specification for application.
Using precision spray equipment, our crews apply the foam in controlled passes to achieve the specified thickness and density. The closed-cell foam expands 30 to 40 times its liquid volume, conforming to every detail of the surface and creating a seamless monolithic barrier.
After the foam cures, we apply a UV-protective coating — silicone, acrylic, or elastomeric — selected for your specific application and climate. We then remove all masking, clean up the work area, and conduct a final walkthrough with you to verify satisfaction.

"Got a comprehensive inspection done on our warehouse roof. They found three areas of trapped moisture that were invisible from the surface. The early detection saved us from much more expensive structural repairs down the road."
"We had a persistent leak that three different contractors could not find. Their team used moisture scanning equipment and pinpointed it to a failed pipe boot in minutes. Fixed it the same day. Incredible diagnostic work."
"Lapolla Industries restored the roof on our distribution warehouse without any disruption to our operations. The crew worked in sections and we never had to shut down. The new reflective coating has already reduced our cooling load."
