North Miami's 1950s ranch homes were built to last, but their original attics and low wood-truss roofs were never designed for the heat and humidity that dominates the Miami climate today. If you own one of these properties in ZIP 33161, your attic is probably working overtime, and so is your air conditioning bill.
Miami Spray Foam Insulation has been serving North Miami and the surrounding Miami area since 2012. We know these neighborhoods, the construction they sit on, and exactly why homeowners here call us when their cooling costs spike, their attics collect moisture, or their insulation has been damaged by roof rats or water intrusion. We show up with a crew that understands slab foundations, concrete block walls, and the kind of attic access that comes with a fifty-year-old home.
Spray Foam Insulation in North Miami (33161)
North Miami's 1950s ranches sit on concrete slabs with no basements or crawl spaces, and their wood-truss attics carry AC handlers and ductwork that run 140 to 160 degrees Fahrenheit most of the year. The problem is simple: thin or deteriorated insulation, no air sealing, and humidity that pushes inward from the tropical climate. Your cooling system has to work harder, your bills climb, and moisture can accumulate in spaces that are hard to see and harder to fix.
Closed cell spray foam stops that. It seals air leaks that blown-in insulation misses, creates a vapor barrier that keeps humidity out, and holds up to the heat. We also work with open cell foam when the application calls for it, and we handle wall injection for hollow concrete block walls that were never insulated when they were built. If your insulation has been damaged by roof rats or water, we remove what has to come out and replace it right.
Our team has been installing spray foam insulation in North Miami and across Greater Miami for over a decade. We show up with fully insured crews, we give you a written estimate with R-value and thickness specifications before we start, and we leave your property clean.

How a Job Works in North Miami
We start with a free on-site assessment. We look at your attic, crawl space, or walls, we measure the area, and we talk through what you are trying to fix. A cooling bill that has gotten out of hand, a room that never reaches temperature, condensation in the attic, or insulation that has failed and needs to come out. We ask questions and we listen. Then we give you a written estimate with the R-value and thickness we are proposing, and a price that reflects the actual scope of work.
On the day of the job, we set up mechanical ventilation in your home. Spray foam has a smell during cure, and ventilation moves it out. We mask off the spaces where we are working, we spray to the thickness and R-value on your estimate, and we manage the job so you can stay in your home. We tell you the re-entry window upfront, usually twenty-four to forty-eight hours depending on the foam type and the weather. If insulation has to come out first because it is wet or contaminated, we do that and haul it away. We do not spray over a wet or leaking substrate, and we will walk away from a job if the moisture has to be fixed first.
When we are done, we clean up. Your attic or crawl space should look like we were never there except for the new foam and the difference it makes to your comfort and your bills.
Attic spray foam insulation in North Miami 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 1,200-square-foot attic in a North Miami ranch might run $1,800 to $3,600 depending on whether you choose open or closed cell and what has to be removed first. Wall injection for hollow concrete block walls starts around $2 per square foot. Crawl space foam starts at $2,500. If your insulation is damaged and has to come out, removal runs from $950 depending on the area and what you are removing. The real cost drivers are the square footage to cover, the R-value and thickness you specify, whether you need removal first, and how tight the access is in your space. We give you a free estimate on the phone at (786) 503-8206, and a detailed written estimate on site with all the specs before we start work.
