Trusted attic insulation in Mendota, IL. Our certified crews deliver precision workmanship and guaranteed results.
If your Mendota home has hot upstairs rooms in summer and cold drafts in winter, your attic insulation is failing. Lapolla Industries replaces underperforming fiberglass and cellulose with spray foam that seals every gap, fills every cavity, and delivers R-6.5 per inch of insulation value.
When Mendota, IL property owners need attic 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 Mendota crews have seen every attic 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 attic insulation results that hold up to Mendota conditions year after year.
From inspection to completion, here is how we deliver professional attic 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.
"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."
"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."
"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."
