“We had them seal and insulate our attic after we noticed drafts around the interior stairwell opening. The crew was professional and got it done in one day. Our heating bills dropped noticeably, and the upstairs is so much more comfortable now.”
Attic Spray Foam Insulation
“Called them for air sealing work in our old house basement entry, there were gaps everywhere around the rim and band joists. They sealed it all up tight and explained what they were doing the whole time. No more cold spots down there.”
Air Sealing
“Needed our attic completely re-insulated and air sealed. They removed the old blown-in stuff, cleaned everything out, and sprayed open cell foam throughout. The access stairwell is now properly sealed too. Fantastic job and the place feels so much warmer.”
Attic Spray Foam Insulation
“Had moisture and cold air coming up through our basement crawl space. These guys came in, sealed it all with closed cell foam, and now the basement stays dry and warm. They were quick, clean, and really knew their stuff.”
Crawl Space Spray Foam Insulation
“We converted our garage into a workshop and needed proper insulation. They sprayed closed cell foam on the walls and ceiling, the temperature control is unreal now. The crew cleaned up every bit of mess and finished on schedule.”
Garage Spray Foam Insulation
“Our old farmhouse had gaps in the walls that we could feel drafts through. They injected foam insulation without tearing anything apart, which was exactly what we needed. The work was done clean and professional, highly recommend them.”
Wall & Injection Foam Insulation
“We're converting a metal building into a living space and needed spray foam insulation on the entire structure. They handled the whole job, walls, ceiling, everything. The quality is excellent and they worked around our timeline perfectly.”
Metal Building & Barndominium Spray Foam
“Our house had hollow walls with almost no insulation, and we didn't want to open them up. They injected closed cell foam into the walls from the outside and sealed everything properly. The energy savings have been worth every penny.”

| Service | Starting from | Description |
|---|---|---|
| Attic Spray Foam Insulation | From $1.50/sq ft | Open-cell foam on the roof deck turns a Kansas City attic into conditioned space through July heat and January cold. 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 basement foundation walls; rim joists; metal buildings and any Kansas City wall where vapor drive flips direction between August and January. |
| 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 between the units of a Midtown fourplex comes with it. We spell out where it belongs, and where a basement wall 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 frame upper stories of Kansas City shirtwaists; Waldo bungalows and post-war ranches with empty cavities. Solid stone and brick walls get an honest no. |
| Crawl Space Spray Foam Insulation | From $2,500 | Closed-cell foam on crawl space walls and subfloors ends cold January floors and damp August air. We foam crawl spaces under kitchen additions; sunrooms and enclosed back porches. Moisture problems get fixed first, we never spray over a wet crawl space. |
| Rim Joist & Band Joist Spray Foam | From $650 | Basement rim joists leak more cold air than almost anything in a Kansas City house. Closed cell seals every bay along the top of the foundation, the small-ticket job with the fastest comfort payback. Cantilevers and bonus-room floors are handled the same way. |
| Garage Spray Foam Insulation | From $1,200 | Garage ceilings under bonus rooms and walls shared with the house are foam-sealed against July heat and January cold. 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 a Missouri metal building from sweating in spring and frosting inside in winter. Shops; barndominiums; pole barns and ag buildings sealed against condensation from Cass and Clay County acreage to riverfront 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 city or county inspector will actually accept. Phased work keeps your operation running from the West Bottoms to the Northland. |
| 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 is common in older Kansas City 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 a hail-damaged roof, or when a new roof is going on anyway. |
| Air Sealing | From $650 | Top plates; can lights; chimney chases and attic hatches leak more heated and cooled air than most walls. We seal the leaks before insulating, the step that makes every R-value actually perform and the cheapest comfort fix in a Kansas City house. |
