Property owners in Darby trust Lapolla Industries for professional crawl space insulation because we combine industry-leading spray foam technology with the local expertise needed to address Pennsylvania climate challenges. Every project begins with a thorough assessment of your property and ends with a warranted solution engineered to last.
Our Darby crawl space insulation crews arrive fully equipped with the latest SPF application systems, safety equipment, and premium materials. We handle every step — from surface preparation and substrate evaluation to final coating and cleanup — so you get a turnkey result with zero hassle and complete confidence in the finished product.
A systematic approach to crawl space insulation that ensures lasting performance.
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.
We prepare every surface according to factory guidelines — cleaning contaminants, addressing moisture, repairing damaged substrate, and verifying adhesion conditions. This step is not glamorous, but it is the foundation of a spray foam system that lasts decades.
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.
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.

"The silicone coating they applied to our metal roof eliminated all the rust spots and sealed every seam and fastener. The reflective finish dropped our cooling costs noticeably. Our building looks ten years newer."
"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."
"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."
