Expert crawl space insulation in Wilmette, IL. Licensed spray foam contractors with manufacturer-backed warranties and free inspections.
If your Wilmette 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 Wilmette, IL 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 Wilmette crews have seen every crawl space insulation scenario Illinois 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 Wilmette conditions year after year.
From inspection to completion, here is how we deliver professional crawl space insulation results.
Our assessment process goes beyond a visual check. We examine substrate conditions, drainage patterns, existing insulation performance, and structural integrity. This data-driven approach ensures we recommend the right spray foam solution for your specific property.
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.
Application is performed by certified spray foam technicians using the latest proportioning equipment. We monitor foam temperature, pressure, and ratio throughout application to ensure every square foot meets manufacturer performance specifications.
The final step is applying a protective topcoat that shields the SPF from UV exposure and provides the weather surface. We select the coating type based on your roof slope, ponding conditions, and desired service life. After coating, we clean up completely and review the finished project with you.

Our reputation is built on results. Here is what our customers have to say.
"Lapolla Industries coated our standing seam metal roof with a reflective system that stopped the leaks at the panel overlaps. The building stays significantly cooler in summer and the coating has held up perfectly through two winters."
"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."
"Had our attic insulated with spray foam after years of fiberglass that kept settling and losing its R-value. Lapolla Industries did a clean install — no gaps, no missed spots. Our HVAC system runs half as much now."
