When Westchester, 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 Westchester 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 Westchester 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.

"Lapolla Industries repaired our flat roof after a section of the membrane started bubbling and lifting. They removed the damaged area, applied new substrate, and sealed everything tight. Solid repair at a fair price."
"Regular maintenance visits twice a year keep our flat roof in great shape. They clean drains, check seams, inspect all penetrations, and send a detailed report with photos. Good preventive program at a reasonable cost."
"Our crawl space was damp, musty, and completely uninsulated. They sealed all the rim joists and band boards with closed-cell foam. The floors above are warmer and the moisture problem is gone. Should have done this years ago."
