“Our attic was a nightmare, hot spots everywhere and the AC running constantly. Miami Spray Foam came out, removed the old fiberglass, and sprayed about 1,200 sq ft of closed cell foam. The difference is night and day. Energy bill dropped noticeably and the place stays cool now without the unit working overtime.”
Attic Spray Foam Insulation
“We were finishing out a new warehouse space and needed air sealing done before the HVAC install. The crew showed up on time, got the whole job done in one day, and their cleanup was thorough, no mess left behind. Professional from start to finish.”
Commercial & New Construction Spray Foam
“Had them spray open cell foam in our cathedral ceiling area. They explained the difference between open and closed cell really well, and open cell was the right call for our space. Good guys, fair pricing, and the work looks clean.”
Open Cell Spray Foam Insulation
“Crawl space was musty and cold. They sealed and insulated the whole thing with closed cell foam, about 800 sq ft. It's dry now, and we can actually feel the difference in the floors above. Really impressed with how they handled the tight space and the attention to detail.”
Crawl Space Spray Foam Insulation
“Converted our garage into a workshop and needed it insulated. Three-person crew knocked it out in a day, walls and ceiling got closed cell spray foam. It's so much more comfortable to work out there now, and the energy efficiency is a bonus.”
Garage Spray Foam Insulation
“Found out we had air leaks around the rim joists, cold drafts in winter, humidity issues. They sealed and foamed the entire perimeter. The difference is subtle but real, and knowing it's done right gives me peace of mind.”
Rim Joist & Band Joist Spray Foam
“We're converting an old metal barn into a barndominium, and these guys handled the spray foam insulation perfectly. They understood the unique challenges of metal buildings and did a stellar job. Can't wait to move in, it's going to be so much more livable now.”
Metal Building & Barndominium Spray Foam
“Got injection foam in our exterior walls during a renovation. The crew drilled, foamed, and patched it all seamlessly, you'd never know they were there. House is warmer, quieter, and the whole process was quick and clean.”

| Service | Starting from | Description |
|---|---|---|
| Attic Spray Foam Insulation | From $1.50/sq ft | Open-cell foam on the roof deck turns a Miami truss attic that runs 150°F into conditioned space. The AC air handler and ductwork overhead end 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 stiffening on the roof deck. It shrugs off flood water better than any other insulation. The right product for elevated floors; metal buildings and anywhere South Florida humidity pushes hardest. |
| 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 raised floor calls for closed cell. |
| Wall & Injection Foam Insulation | From $2/sq ft | Injection foam fills closed walls through small drilled ports, no demolition. In Miami that means the hollow cores of concrete block walls and the furred cavities behind interior plaster; plus frame walls on older Coconut Grove homes. Ports are patched to match the stucco. |
| Crawl Space Spray Foam Insulation | From $2,500 | Most Miami homes sit on slab, but older frame homes and new elevated houses have open undersides. Closed-cell foam on the subfloor holds back humid air and survives flood water. Standing water and drainage get fixed first, we never spray over wet ground. |
| Rim Joist & Band Joist Spray Foam | From $650 | Cantilevered bonus rooms, elevated homes and second-floor additions 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 heat. Permitted garage conversions and workshops are handled the same way. The difference between a storage oven and usable square footage. |
| Metal Building & Barndominium Spray Foam | From $1.75/sq ft | Closed-cell foam is the insulation that stops a South Florida metal building from dripping. Nursery and farm buildings; boat barns; shops and barndominiums sealed against condensation from Redland acreage to Medley and Hialeah 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 Miami-Dade or Broward inspector will actually accept. Phased work keeps your operation running from Doral to the Medley industrial belt. |
| Insulation Removal | From $950 | Old blown-in and batts vacuumed out before any new foam goes in, never buried. Roof-rat contamination and storm-wet material come out with it. 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; rat-fouled; soaked by a hurricane 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 Miami house all year. We seal them before insulating, it cuts the sticky feel indoors and is the cheapest comfort fix in South Florida. |
