Aventura's condo towers and townhomes sit on concrete slabs with low wood-truss attics carrying AC ductwork that runs 140 to 160 degrees most of the year, and the tropical humidity pushes moisture inward year-round. Miami Spray Foam Insulation has been sealing and insulating homes across Greater Miami since 2012, and we know exactly what Aventura (33180) needs to stay cool, dry, and comfortable.
Homeowners and property managers in Aventura call us when cooling bills climb, when a unit never reaches temperature, or when condensation and damp insulation show up in the attic. We spray closed-cell and open-cell foam, seal air leaks around rim joists and band joists, remove contaminated or failed insulation, and handle phased work around occupied floors in multi-unit buildings. Our team is fully insured for commercial and new construction spray foam and air sealing, and we write every estimate with R-value and thickness specs so you know what you are getting.
Spray Foam Insulation in Aventura (33180)
Aventura's building stock is mostly concrete-block construction with hollow walls and low attics. The AC air handler and ductwork live in that attic, where temperatures climb to 140 to 160 degrees during the cooling season. Heat radiates down through the roof deck and into the living space below, and the tropical humidity means vapor drive is always pushing inward. Standard fiberglass batts do not stop that heat or seal the air leaks around the ductwork, and they absorb moisture in a humid attic. Closed-cell spray foam stops the heat, seals the leaks, and sheds moisture. Open-cell foam works in conditioned spaces where the humidity is controlled. Wall cavities in concrete-block homes are often hollow and uninsulated, and injection foam fills them without tearing apart the exterior stucco or the interior drywall. Crawl spaces are rare in Aventura, but when they exist they are damp, and closed-cell foam on the rim joists and band joists stops the moisture and the temperature swing.
We have been serving Aventura and the Miami area since 2012. We know the building code that applies at your address, we coordinate with your building department and your HOA if you have one, and we schedule work around occupied units so tenants are not displaced.

How a Job Works in Aventura
We start with a free on-site assessment. We look at your attic, your walls, your crawl space or rim joists, and we talk about what you are trying to fix: a cooling bill that is too high, a room that will not stay comfortable, moisture or condensation, or insulation that has failed and needs to come out. We explain what foam type makes sense for your space, what R-value and thickness the energy code calls for at your address, and what it will cost. You get a written estimate with R-value and thickness specs before we touch anything.
On the day of the work, we set up mechanical ventilation in your attic or crawl space. If there is old insulation that has to come out, we remove it first and haul it away. We spray the foam in controlled passes, holding the thickness and the ratio steady so the foam cures properly. We do not spray over wet, moldy or contaminated insulation, and we do not spray over a leaking roof or standing water. We fix the moisture first or we walk away. Occupied units stay ventilated during the cure window, which is 24 to 48 hours depending on conditions.
When the foam has cured, we do a final walkthrough with you, answer your questions, and leave your property clean. We haul away all equipment and debris.
Attic spray foam in Aventura typically runs from $1.50 per square foot for open-cell foam to $1.20 per board foot for closed-cell, depending on the thickness and R-value you need. Wall injection foam runs from $2 per square foot. Rim joist and band joist sealing starts at $650. Crawl space foam starts at $2,500. Insulation removal runs from $950 depending on the volume and what has to be hauled away. The biggest cost factors are the area to cover, the R-value and thickness the code requires, whether you are using open or closed cell, and whether old insulation has to come out first. We give you a free estimate on site with all the numbers spelled out. Call us at (786) 503-8206 to schedule your assessment.
