Cutler Bay's post-Andrew concrete-block homes are hitting the age where attic insulation has flattened, cooling bills climb, and moisture starts to creep in. Miami Spray Foam Insulation has been serving Cutler Bay (33189) and the surrounding Miami area since 2012, helping homeowners in your neighborhood seal the gaps and recover the comfort their homes lost.
Your home sits on a concrete slab with walls of concrete block, and above that a low wood-truss attic where the AC air handler and ductwork run 140 to 160 degrees most of the year. That heat, combined with the tropical humidity that pushes inward year-round, is why spray foam insulation and air sealing work so well in Cutler Bay. We know the building stock here, the moisture challenges that come with it, and how to fix them right.
Spray Foam Insulation in Cutler Bay (33189)
Cutler Bay rebuilt after Hurricane Andrew under the strictest wind code in the country. Your home's roof is tied down tight, the walls are solid concrete block, and the attic above is small and tight. That means access can be cramped, but it also means spray foam does exactly what you need: it seals every gap, it stops the heat from radiating down through the roof deck, and it stops the humid air from condensing on cold ductwork in summer. Closed-cell foam is the right choice for most Cutler Bay attics because it handles the moisture load, resists the heat, and adds structural strength to an older truss system. Open-cell foam works for some jobs too, but the tropical climate here makes closed-cell the standard recommendation.
Hollow concrete-block walls are common in Cutler Bay, and many homes were built with little or no cavity insulation. Wall injection foam fills those hollow cores and stops the temperature swings that make rooms uncomfortable. If your home has a crawl space or rim joist (less common here on the slab, but we see them), spray foam seals those too. Our team has been doing this work in Miami and Cutler Bay for over a decade. We show up with fully insured crews, we do the work right, and we stand behind it.

How a Job Works in Cutler Bay
Step one is a free on-site visit. We walk your attic, crawl space or walls, measure the area, check for any moisture or contamination that has to be addressed first, and talk through what you want to accomplish. We give you a written estimate with the R-value and thickness specified, so you know exactly what you are paying for. No surprises.
Step two is the spray. We set up mechanical ventilation so the smell stays controlled during the cure, we spray to the thickness and R-value in the estimate, and we keep your home as clean as we can. In a tight Cutler Bay attic with ductwork and an air handler already in place, we work around what is there. If old insulation has to come out first, we remove it and haul it away. If the substrate is wet or contaminated, we fix the moisture first or we walk away. You do not pay us to cover up a problem.
Step three is cleanup and a final walkthrough. We leave your property clean, answer your questions about the re-entry window (typically twenty-four to forty-eight hours for full cure), and stay reachable if anything comes up. You get our phone number and you can call it.
Attic spray foam insulation in Cutler Bay typically runs from $1.50 per square foot for open-cell to $1.20 per board foot for closed-cell, depending on the thickness and R-value you need. A typical Cutler Bay attic of 1,200 to 1,500 square feet might run $2,000 to $4,500 for a full closed-cell spray. Wall injection foam for hollow concrete block runs from $2 per square foot. Crawl space foam starts at $2,500. If old insulation has to come out first, removal runs from $950 depending on the area and what is in there. The biggest cost factors are the square footage or board footage to cover, the R-value and thickness you specify, whether you choose open or closed cell, and what has to be removed or fixed before we spray. Every job is different. Call us at (786) 503-8206 for a free estimate. We will walk through your home, measure carefully, and give you a firm price in writing.
