Our proven process ensures quality results on every spray foam project.
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.

"Lapolla Industries installed a spray foam roof on our warehouse last spring. Their crew was thorough, professional, and finished ahead of schedule. The building stays cooler in summer and the roof looks pristine a year later."
"Had spray foam applied to our flat commercial roof and the difference is night and day. No more ponding water, energy bills dropped noticeably, and the seamless membrane means zero leak points. Should have done this years ago."
"Instead of a full tear-off our old commercial roof got a complete restoration — cleaned, repaired, and recoated with a reflective silicone system. Saved us tens of thousands compared to replacement and it looks brand new."
