Our Crawl Space Insulation Process

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

1

Inspection & Assessment

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.

2

Surface Preparation

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.

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

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.

What Our Customers Say

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

★★★★★

"We signed up for their annual roof maintenance program for our three commercial buildings. They catch small issues before they become expensive repairs. Last inspection they found a failing pipe boot that would have caused a major leak."

— Diane Holloway
★★★★★

"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."

— Karen Delgado
★★★★★

"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."

— Maria Zuniga
