“Had them spray foam my attic after we noticed our AC bills were out of control. The crew sealed up all the gaps around the roof line and sprayed about 1,200 square feet with open cell foam. Made a huge difference, the house stays so much more comfortable now and I'm already seeing lower energy costs.”
Attic Spray Foam Insulation
“We wanted to turn our attic into a bonus room, so we needed proper insulation on the roof deck. Indianapolis Spray Foam came out and did a closed cell spray foam job that was perfect, sealed everything tight, the R-value is excellent, and now that space is actually usable year-round. Their crew was in and out in one day and cleaned up after themselves without us having to ask.”
Attic Spray Foam Insulation
“Our old house had so many air leaks we could feel drafts everywhere. These guys came in and did a thorough air sealing job, focusing on the interior walls and gaps we didn't even know existed. The difference is noticeable, no more cold spots in winter.”
Air Sealing
“Had a cold basement that was costing us money. They came out and sprayed closed cell foam on all the rim joists and band joists around the perimeter. It's night and day, basement is warmer, and we're not losing heat through those gaps anymore. Really professional crew, knew exactly what they were doing.”
Rim Joist & Band Joist Spray Foam
“Insulated our attached garage with open cell spray foam so we can use it as a workshop without freezing. They did about 800 square feet of walls and ceiling, and the temperature control is so much better now. Only minor thing, they had to move some of our storage, but they put it all back neat.”
Garage Spray Foam Insulation
“Crawl space was a mess, cold, damp, and we were losing heat like crazy. They sealed it up with closed cell foam and did air sealing around all the rim joists. Place feels so much warmer and we haven't had moisture issues since.”
Crawl Space Spray Foam Insulation
“We converted an old barn into a living space and needed serious insulation. They sprayed closed cell foam on the metal roof and walls, about 2,000 square feet total. The place is now climate-controlled and actually comfortable to live in. Couldn't have done this conversion without them.”
Metal Building & Barndominium Spray Foam
“Old house, thin walls, terrible insulation. They drilled and injected closed cell foam into the walls on the north side of the house. Took about half a day, minimal mess, and those rooms are finally warm in winter.”

| Service | Starting from | Description |
|---|---|---|
| Attic Spray Foam Insulation | From $1.50/sq ft | Open-cell foam on the roof deck turns an Indianapolis attic into conditioned space, from 140°F July to sub-zero January. The ductwork ends up inside the envelope. Every estimate lists the R-value target; the thickness per pass; the 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 crawl space walls; basement rims; pole barns and any Indianapolis wall that has to survive a sub-zero January and a humid August. |
| 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 and the two halves of a double comes with it. We say where it belongs, and where a crawl space 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 Indianapolis frame cottages; balloon-framed doubles and post-war ranches with empty cavities. Ports go under a siding course or along a mortar joint and are patched to match. |
| Crawl Space Spray Foam Insulation | From $2,500 | Closed-cell foam on crawl space walls and rims stops cold floors and frozen pipes in Indianapolis homes. Ranches; Cape Cods and newer suburban two-stories sit on them. Moisture gets fixed first, we never spray over a wet crawl space. |
| Rim Joist & Band Joist Spray Foam | From $650 | Basement and crawl space rim joists leak more cold air than almost anything in an Indianapolis house. Closed cell seals every bay along the top of the foundation, the small-ticket job with the fastest comfort payback. Cantilevers get the same treatment. |
| Garage Spray Foam Insulation | From $1,200 | Garage ceilings under bonus rooms and shared walls are foam-sealed against July heat and sub-zero nights. Workshop conversions are handled the same way. The difference between a storage box and usable space twelve months a year. |
| Metal Building & Barndominium Spray Foam | From $1.75/sq ft | Closed-cell foam stops an Indiana pole barn from sweating in spring and frosting inside in winter. Post-frame shops; barndominiums; machine sheds and steel buildings sealed against condensation from Boone County farms to Plainfield warehouses. |
| Commercial & New Construction Spray Foam | Free commercial estimate | Warehouses; offices; churches and production builders served on schedule. Code-compliant assemblies come with documentation your local building inspector will actually accept. Phased work keeps your operation running from the Plainfield logistics corridor to Whitestown. |
| Insulation Removal | From $950 | Old blown-in and batts vacuumed out before any new foam goes in, never buried. We also cut out failed spray foam; the job most installers will not touch. Vermiculite turns up in older Indianapolis attics and 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; mouse-fouled; soaked by an ice dam leak or simply twenty years past its job. |
| Air Sealing | From $650 | Top plates, can lights, chimney chases and attic hatches leak more heated air than most walls. That warm leak is what builds ice dams. We seal them before insulating, the cheapest comfort fix in Indianapolis. |
