Fort Lauderdale's mix of 1950s ranches on the canals and newer elevated homes sits in a climate where your attic runs 140 to 160 degrees most of the year, your walls are concrete block under stucco, and humidity pushes inward relentlessly. Spray foam insulation and air sealing stop the heat loss, the moisture, and the ductwork sweat that drains your cooling bill.
Miami Spray Foam Insulation has been serving Fort Lauderdale and the surrounding area since 2012. We know the neighborhood's construction, the seasonal pressure on your AC system, and what happens when an attic isn't sealed tight. When homeowners in 33301 call us, they're usually facing a room that won't cool, a condensation problem in the attic, or an insulation job that has to come out before anything else can happen.
Spray Foam Insulation in Fort Lauderdale (33301)
Fort Lauderdale's building stock tells the story. The older ranches along the canals have thin attic fill and hollow concrete block walls with no cavity insulation. Newer elevated homes built after hurricane code tightened in the 1990s carry better framing but often the same challenge: a low wood-truss attic packed with AC ductwork running at peak temperature nine months a year, and no air sealing to stop the heat from leaking out at the rim, the band joist, or through the walls themselves. Concrete slab foundations mean no crawl space in most homes, but when one exists, humidity and condensation are the rule, not the exception. The tropical climate means vapor drive is always pushing inward, and roof leaks or attic moisture problems drive constant resets.
Our team has sealed attics in 1950s ranches, injected foam into the hollow cores of concrete block walls, sealed rim joists on canal-front homes, and removed contaminated insulation before starting fresh. We understand the access constraints in a tight attic, the need to work around occupied homes, and the importance of mechanical ventilation during cure so your family can re-enter safely within 24 to 48 hours.

How a Job Works in Fort Lauderdale
We start with a free on-site assessment. We look at your attic, walls, crawl space or rim joist, measure the area to be covered, and discuss whether you need closed cell foam (higher R-value, better for moisture control and structural strength) or open cell foam (lower cost, good for sound control and air sealing in dry applications). We'll tell you honestly if the existing insulation has to come out first, and we'll price that removal separately so you know what you're paying for.
On the day of the work, our fully insured crew arrives with the spray equipment, sets up mechanical ventilation to manage odor and off-gassing, and applies the foam to the specified thickness and R-value. We protect floors, fixtures and HVAC equipment. In a tight attic or a home with ductwork running through the space, we work methodically to hit every seam, rim, band joist and air leak. If we find a wet substrate, active condensation or a roof leak, we stop and explain what has to be fixed first. We don't spray over moisture.
Once the foam has cured, we clean up and walk through the property with you. Your attic, walls or crawl space are sealed tight, the R-value and thickness are documented in your estimate, and the work is backed by our workmanship warranty.
Attic spray foam in Fort Lauderdale 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 your home needs. A 1,500 square foot attic with closed cell foam at 3 inches (R-18) might land in the $2,500 to $4,000 range. Wall injection into concrete block runs from $2 per square foot. Crawl space work starts at $2,500. Insulation removal and replacement varies by volume and contamination level, starting at $950 for removal and $2,800 for a full re-insulation job. The cost depends on the area to cover, what has to be removed first, whether you choose open or closed cell, and your target R-value. Call us at (786) 503-8206 for a free written estimate with R-value and thickness specs. We'll give you a realistic number based on what your home actually needs.
