“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.”
Attic Spray Foam Insulation
“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.”
Open Cell Spray Foam Insulation
“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.”
Attic Spray Foam Insulation
“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.”
Garage Spray Foam Insulation
“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.”
Garage Spray Foam Insulation
“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.”
Rim Joist & Band Joist Spray Foam
“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.”
Metal Building & Barndominium Spray Foam
“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.”

| Service | Starting from | Description |
|---|---|---|
| Attic Spray Foam Insulation | From $1.50/sq ft | Open-cell foam on the roof deck turns a McAllen attic that hits 160°F under Valley sun into conditioned space. The air handler and ductwork overhead end up inside the envelope. Every estimate lists the R-value; thickness per pass and board footage. |
| Closed Cell Spray Foam Insulation | From $1.20/board ft | Two-pound closed-cell foam delivers R-6.5 per inch with its own vapor retarder and real stiffening on the roof deck. It shrugs off flood water. The right product for cold storage; metal buildings; packing sheds and any wall facing Valley heat and Gulf humidity. |
| Open Cell Spray Foam Insulation | From $0.55/board ft | Half-pound open-cell foam air-seals attics and interior walls at a friendlier price per board foot. Sound dampening between bedrooms and between townhome units comes with it. We spell out where it belongs, and where flood exposure or a cold room calls for closed cell. |
| Wall & Injection Foam Insulation | From $2/sq ft | Injection foam fills closed walls through small drilled ports, no demolition. The retrofit answer for the Valley's 1960s-80s brick-veneer and frame-and-stucco ranches with hot west walls. Ports go along a mortar joint or through the stucco and are patched to match. |
| Crawl Space Spray Foam Insulation | From $2,500 | Older pier-and-beam houses in Mission, Harlingen and historic Brownsville have open undersides. Closed-cell foam on the subfloor holds back humid Gulf air and survives flood water. Drainage gets fixed first. |
| Rim Joist & Band Joist Spray Foam | From $650 | Bonus-room floors, cantilevers and band joists leak cooled air at every framing gap. A closed-cell pass seals them for good; the small-ticket job with the fastest comfort payback. |
| Garage Spray Foam Insulation | From $1,200 | Garage ceilings under bonus rooms and walls shared with the house are foam-sealed against radiant Valley heat. Workshop conversions are handled the same way. The difference between a storage oven and usable space. |
| Metal Building & Barndominium Spray Foam | From $1.75/sq ft | Closed-cell foam is the insulation that stops a Rio Grande Valley metal building from baking and dripping. Citrus packing sheds; farm shops; barndominiums and ag storage sealed against heat gain and condensation from Mission groves to Willacy County farms. |
| Commercial & New Construction Spray Foam | Free commercial estimate | Warehouses; cold storage; offices; churches and production builders served on schedule. Code-compliant assemblies come with documentation your inspector will actually accept. Phased work keeps your operation running from the Pharr produce corridor to the McAllen trade zone. |
| Insulation Removal | From $950 | Old blown-in and batts vacuumed out before any new foam goes in, never buried. Storm-soaked material; rodent nests and moldy fill come out with it. We also cut out failed spray foam; the job most installers will not touch. Vermiculite gets flagged for testing. |
| Insulation Replacement & Re-Insulation | From $2,800 | The full reset: old material removed; gaps air-sealed; new foam installed to current code R-values. The right call when insulation is flattened; rodent-fouled; soaked by a hurricane or flood roof leak, or when a new roof is going on anyway. |
| Air Sealing | From $650 | Top plates; can lights; chases and attic hatches pull humid outside air into a Valley house all year. We seal the leaks before insulating, it cuts the sticky feel indoors and is the cheapest comfort fix in the Rio Grande Valley. |
