Our Attic Insulation Process

A systematic approach to attic insulation that ensures lasting performance.

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

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.

3

SPF Application

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.

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.

★★★★☆

"Regular maintenance visits twice a year keep our flat roof in great shape. They clean drains, check seams, inspect all penetrations, and send a detailed report with photos. Good preventive program at a reasonable cost."

— Kenneth Ostrowski
★★★★★

"We manage a 40,000 square foot retail center and the roof was near end of life. Instead of tearing it off they restored it with a spray foam and coating system. Saved us over sixty percent versus replacement and added twenty years of life."

— Mark Townsend
★★★★☆

"Had our entire warehouse roof restored with a spray-applied coating system. The crew worked around our operations without any disruption. The finished roof reflects heat beautifully and our AC runs less. Win-win."

— Brian Ashworth
