“We had Austin Spray Foam come out to insulate our attic after we noticed the AC running constantly. They sprayed about 1,200 sq ft of open cell foam and sealed all the air leaks around the vents and penetrations. The crew was in and out in one day, super professional, and our energy bills dropped noticeably within the first month. Really impressed with the results.”
Attic Spray Foam Insulation
“Austin Spray Foam did air sealing work in our hallway ceiling where we had a trap door access to the attic. They sealed everything with closed cell foam and the difference in air drafts is night and day. Cleanup was thorough, no mess left behind. Couldn't ask for better service.”
Air Sealing
“Had them spray foam our attic conversion project. The crew did a great job getting into all the tight spots under the rafters and around the wooden beams. It's made the upstairs so much more comfortable and quiet. Took them about 3 days to finish the whole job, and they were careful not to disturb anything else in the space.”
Attic Spray Foam Insulation
“We called Austin Spray Foam to insulate and seal our crawl space foundation area. The team was knowledgeable about moisture issues and recommended closed cell foam for our situation. They got under there and did a thorough job. Haven't had any moisture problems since, and the house feels warmer in winter.”
Crawl Space Spray Foam Insulation
“Just had them finish insulating our garage with open cell spray foam. Three guys showed up, got the job done in half a day, and the garage is actually comfortable now instead of being a freezer in winter. They covered everything properly and cleaned up after themselves.”
Garage Spray Foam Insulation
“Austin Spray Foam handled the insulation for our new attic access and staircase project. They sealed the perimeter with spray foam and made sure everything was airtight. The attention to detail around the access points was excellent.”
Attic Spray Foam Insulation
“We're converting a metal building into a barndominium and Austin Spray Foam did the interior spray foam insulation. They understood the unique challenges of metal structures and did a fantastic job. The space is now properly insulated and the spray foam really helped with temperature control and sound dampening.”
Metal Building & Barndominium Spray Foam
“Had them inject foam into the walls of our older home during a renovation. The crew drilled strategically, filled the cavities, and patched everything back up. We didn't expect such a dramatic difference in how the house feels, but it's warmer and the heating bills are down.”

| Service | Starting from | Description |
|---|---|---|
| Attic Spray Foam Insulation | From $1.50/sq ft | Open-cell foam on the roof deck turns a 150°F Austin attic into conditioned space. Ductwork and attic water lines end up inside the envelope, a lesson Winter Storm Uri taught. 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 structural stiffening. The right product for metal buildings and barndominiums; pier-and-beam subfloors and any Austin wall that has to handle both August heat and a hard freeze. |
| Open Cell Spray Foam Insulation | From $0.55/board ft | Half-pound open-cell foam air-seals attics and walls at a friendlier price per board foot. Sound dampening between rooms comes with it. We spell out where it belongs, and where a metal building or pier-and-beam floor calls for closed cell instead. |
| Wall & Injection Foam Insulation | From $2/sq ft | Injection foam fills closed walls through small drilled ports, no demolition. The retrofit answer for Austin's 1950s-60s ranches with empty cavities behind brick or limestone veneer and for older frame bungalows with wood siding. Ports are patched to match. |
| Crawl Space Spray Foam Insulation | From $2,500 | Closed-cell foam on pier-and-beam subfloors and crawl space skirts stops cold floors and holds back humid summer air. Central Austin's bungalows sit on them. Moisture and drainage get fixed first, we never spray over a wet crawl space. |
| Rim Joist & Band Joist Spray Foam | From $650 | Band joists; cantilevers and bonus-room floors over garages leak conditioned air at every framing gap. A closed-cell pass seals them for good, the small-ticket job with the fastest comfort payback in an Austin house. |
| Garage Spray Foam Insulation | From $1,200 | Garage ceilings under bonus rooms and walls shared with the house are foam-sealed against radiant afternoon 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 Texas metal building from sweating. Barndominiums; shops; pole barns and ag buildings sealed against condensation from Liberty Hill and Dripping Springs acreage to the east Travis industrial belt. |
| Commercial & New Construction Spray Foam | Free commercial estimate | Warehouses; 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 east Travis industrial belt to the Taylor and Hutto corridor. |
| Insulation Removal | From $950 | Old blown-in and batts vacuumed out before any new foam goes in, never buried. Pipe-soaked material comes out too. We also cut out failed spray foam; the job most installers will not touch. Vermiculite gets flagged for testing; never disturbed. |
| 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; soaked by a frozen pipe or a roof leak; or twenty years past its job. |
| Air Sealing | From $650 | Top plates; can lights; chases and attic hatches leak more cooled air than most walls. We seal the leaks before insulating, the step that makes every R-value actually perform; the first fix an energy audit points to and the cheapest comfort fix in Austin. |
