Trusted crawl space insulation in Des Plaines, IL. Our certified crews deliver precision workmanship and guaranteed results.
Crawl space encapsulation with spray foam in Des Plaines transforms a liability into an asset. Our closed-cell foam provides insulation, vapor barrier, and air sealing in one application — eliminating the condensation, mold risk, and energy waste that plague vented crawl spaces in Illinois.
The buildings and homes of Des Plaines, IL face unique challenges — from seasonal temperature extremes to storm exposure — that demand roofing and insulation systems built for performance, not just price. Lapolla Industries delivers crawl space insulation solutions using closed-cell spray polyurethane foam that outperforms conventional materials in every measurable category.
Our Des Plaines customers see the difference in their energy bills, their comfort levels, and the longevity of their roofing systems. Spray foam does not degrade like fiberglass, does not develop seam failures like TPO, and does not crack like built-up roofing. It is a permanent solution — and Lapolla Industries is the permanent partner Des Plaines property owners rely on to deliver it right.
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.

Spray foam delivers the highest R-value per inch, creates a seamless air and moisture barrier, conforms to any surface shape, and bonds permanently to the substrate. For crawl space insulation applications, this combination of properties outperforms all conventional alternatives.
Yes. Spray foam can be applied year-round in Des Plaines as long as surface temperatures are above 40 degrees Fahrenheit. Our crews monitor substrate temperature and ambient conditions to ensure proper foam curing and adhesion regardless of season.
Absolutely. Once cured, spray polyurethane foam is inert and non-toxic. Our Des Plaines crews follow all OSHA safety protocols during application, including full PPE and ventilation procedures. The foam cures within minutes and is safe immediately after.
Real feedback from property owners who trusted Lapolla Industries with their spray foam projects.
"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."
"Had a few spots where birds had pecked through the coating on our foam roof. The repair crew patched every spot and applied a fresh topcoat over the entire section. Looks brand new and no more leaks."
"Our old three-layer built-up roof was beyond saving. They stripped everything down to the deck, repaired the substrate, and installed a new spray foam roofing system. The building is better insulated now than it has ever been."
