“We needed our attic access sealed up properly because we were losing so much conditioned air up there. The crew came out, assessed the whole situation, and sprayed closed cell foam around the attic hatch and framing. They were done in about 2 hours and the difference in our energy bills is already noticeable. Great work.”

“Had them come out to handle the ceiling area in our hallway where we had a skylight opening that was causing drafts and heat loss. They used open cell foam to seal and insulate the entire perimeter, really professional crew, super clean, and they explained everything as they went. Can't complain at all.”

Mission

“We converted our attic into usable living space and needed proper insulation before drywall went up. McAllen Spray Foam came in and did the whole attic, must've been about 800 square feet, with closed cell foam. The air sealing was top-notch, and they cleaned up every bit of overspray. Our upstairs is finally comfortable year-round.”

“Got our garage insulated before we finished the interior. The team came out, sprayed the walls and ceiling with open cell foam, and sealed all the air leaks around the door frames and rim joists. Took them about a day, and now the garage stays so much more temperature-stable. Really impressed with the quality.”

“We're finishing out our garage as a workshop and needed insulation before we put in the flooring and interior walls. These guys sprayed closed cell foam on all four walls and the ceiling, caught every crack and seam. The air sealing they did around the garage door opening made a huge difference. Very satisfied.”

“Found out we had a lot of air infiltration coming through our attic access hatch and the rim joist area. McAllen Spray Foam sealed the whole thing up with closed cell foam, took about half a day. The crew was respectful, didn't track anything through the house, and the improvement is instant.”

“We're building an agricultural metal structure and needed spray foam insulation for the walls and roof decking. The crew handled the entire project, must've sprayed about 3,000 square feet of closed cell foam. They were organized, efficient, and the insulation coverage is flawless. Exactly what we needed for a climate-controlled barn space.”

Brownsville

“Our interior walls in the addition weren't insulated, so we had them come in and do closed cell foam injection before we closed everything up. The crew drilled access points, filled the cavities cleanly, and sealed everything back up. It's made a noticeable difference in comfort and heating costs. Definitely recommend them.”
