“We had them seal up our attic access area with spray foam and it made such a difference. The crew was in and out in about 3 hours, and they cleaned up every bit of mess. Our upstairs is finally staying warm in winter.”

“Really impressed with how they handled our attic project. They sealed around the access hatch area and the whole attic space with open cell foam. The difference in our energy bills was noticeable right away.”

“Our old attic had almost no insulation left, so we called St Louis Spray Foam to re-insulate the whole thing. They removed the deteriorated stuff and sprayed open cell foam throughout. The crew was professional and the work looks great. Only thing is they took a bit longer than estimated, but the quality made up for it.”

“Had them come out to seal air leaks around our ventilation penetrations in the attic. Small job but they treated it like it mattered, which it does when you're trying to control your heating costs.”

“Converted our garage into a workshop and needed it insulated. They sprayed closed cell foam on all the walls and the overhead door area. It's night and day, stays warm in winter and I can actually work out there now without freezing.”

“We had a cold basement and our energy guy recommended sealing the rim joists. St Louis Spray Foam came in, foamed the entire perimeter band joist area with closed cell, and it stopped the drafts completely. Very satisfied with the results.”

“We're finishing a metal barn into living space out in the country and needed the whole thing insulated. They sprayed closed cell foam on the walls and roof deck, about 2,400 square feet. Professional crew, stayed on schedule, and the insulation job is solid.”

“Our 1950s house had zero insulation in the exterior walls. Instead of tearing everything apart, they drilled and injected closed cell foam into the cavities. Three days of work and we went from freezing to comfortable. Wish we'd done it sooner.”
