When O'Fallon, MO 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 O'Fallon crews have seen every attic insulation scenario Missouri weather can create.

Our Attic Insulation Process

From inspection to completion, here is how we deliver professional attic insulation results.

1

Inspection & Assessment

Every project begins with a thorough inspection of your property. We evaluate the existing condition, identify problem areas, and use infrared moisture scanning when needed to reveal hidden issues. You receive a detailed report with photos and honest recommendations.

2

Surface Preparation

Our preparation process includes substrate inspection, cleaning, moisture testing, and priming. We mask all areas not receiving foam, set up containment where needed, and verify that temperature and humidity conditions are within specification for application.

3

SPF Application

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.

4

Protective Coating & Cleanup

After the foam cures, we apply a UV-protective coating — silicone, acrylic, or elastomeric — selected for your specific application and climate. We then remove all masking, clean up the work area, and conduct a final walkthrough with you to verify satisfaction.

What Our Customers Say

Real feedback from property owners who trusted Lapolla Industries with their spray foam projects.

★★★★☆

"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."

— Dennis Enriquez
★★★★★

"We needed our concrete roof deck waterproofed before installing new equipment on it. The crew applied a monolithic membrane that handles foot traffic and ponding water. Two years in and zero issues. Money well spent."

— Steven McAllister
★★★★★

"Lapolla Industries does our annual roof inspections across four properties. Every report includes current condition ratings, remaining life estimates, and prioritized repair recommendations. Data-driven and extremely useful for budgeting."
