With over two decades of spray foam experience, our Durham crews have seen every crawl space insulation scenario North Carolina 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 Durham conditions year after year.
From inspection to completion, here is how we deliver professional crawl space insulation results.
Before any work begins, our certified inspectors evaluate your property and provide a comprehensive assessment including current condition, repair needs, and recommended SPF solutions. You get a written estimate with no hidden fees.
Proper surface preparation is critical for spray foam adhesion and long-term performance. Our crews clean, dry, and prime all surfaces, remove debris and loose material, and ensure the substrate meets manufacturer specifications before any foam is applied.
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.
We finish every project with the appropriate protective coating, thorough cleanup, and a detailed walkthrough. You receive project documentation including photos, material specifications, warranty registration, and maintenance recommendations.

Real feedback from property owners who trusted Lapolla Industries with their spray foam projects.
"Our metal warehouse roof had been leaking at the ridge and sidewall transitions for years. The coating crew sealed every penetration, fastener, and seam. Completely watertight now and the energy savings are a great bonus."
"Our corrugated metal roof was rusting at every fastener and seam. They cleaned the entire surface, treated the rust, and applied a thick elastomeric coating. The roof looks brand new and is completely sealed now."
"Instead of a full tear-off our old commercial roof got a complete restoration — cleaned, repaired, and recoated with a reflective silicone system. Saved us tens of thousands compared to replacement and it looks brand new."
