Professional attic insulation for Stratham property owners. Lapolla Industries delivers lasting results with industry-leading SPF technology.
If your Stratham 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.
In Stratham, NH, the difference between a spray foam job that lasts and one that fails comes down to the contractor. Lapolla Industries applies the same quality standards to every attic insulation project that earned us a reputation as one of the nation's most trusted SPF specialists — proper surface prep, correct foam thickness, and factory-specified coating application.
Every attic insulation project we complete in Stratham is backed by both manufacturer material warranties and our own workmanship guarantee. We document every step with photos and measurements, provide you with a detailed project report, and remain available for warranty service and maintenance throughout the life of your SPF system.
Our proven process ensures quality results on every spray foam project.
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.

Honest reviews from property owners who chose Lapolla Industries for their roofing and insulation needs.
"Had spray foam applied to our crawl space walls and rim joists. The difference in floor temperature upstairs is dramatic. Our furnace cycles less and the energy savings paid for the project faster than they estimated."
"Our 18-year-old roof was showing its age but still structurally sound. Lapolla Industries recommended restoration over replacement and it was the right call. New coating, sealed seams, and a 15-year warranty. Smart investment."
