A full reset for Houston attics twenty years past their job

Included in your service

Learn more→

Air Sealing

The cheapest comfort fix in a Houston house, and it comes first

Included in your service

  • Top plates, wiring chases, can lights and the attic hatch

“We had Houston Spray Foam come out to insulate our attic after we noticed our AC bills were insane. They sprayed about 1,200 square feet with open cell foam and sealed everything up tight. The crew was professional, in and out in one day, and honestly the difference in our energy bills has been amazing.”

“Our crawl space was a nightmare, cold floors, moisture issues, the whole deal. Houston Spray Foam came in and did a full closed cell spray foam application down there. The work is solid and we're already noticing our house is warmer and drier.”

“We're finishing a barndominium on our property and needed the metal structure insulated properly. These guys know what they're doing with metal buildings, they sprayed closed cell foam on about 2,000 square feet of wall and roof area. Professional crew, fast turnaround, and the insulation is perfect.”
