From oceanfront condos to Boca estates, we install the insulation systems behind the most comfortable, efficient homes in Miami-Dade, Broward, and southern Palm Beach, quietly, cleanly, and on time. Our foreman-led crews have handled the attics, walls, and mechanical spaces of over 2,300 South Florida homes since 2012, so every recommendation is grounded in what actually works in this climate, not a national average.
From a quick attic top-up to a whole-home spray foam installation, our in-house crews handle every type of insulation project in South Florida, residential, commercial, condo, and beachfront.
Open and closed-cell polyurethane that air-seals and insulates in one application. Built for South Florida humidity, hurricanes, and serious energy savings. Closed-cell foam adds rigidity to roof decks and walls, which matters when a home has to meet hurricane wind-load requirements, while open-cell foam is a lower-cost option for interior walls and sound dampening. Because the foam expands to fill every gap around wiring, plumbing penetrations, and irregular framing, it eliminates the air leaks that fiberglass batts and loose blown-in material can't reach, which is usually where the biggest comfort complaints in older South Florida homes come from.
Get Spray Foam QuoteThe highest-ROI upgrade in almost every South Florida home. Bring attics to R-38 or R-49 with proper baffles, air sealing, and hatch insulation. Most homes built before the mid-2000s were insulated to a code standard that no longer matches today's energy costs, and attic temperatures here can exceed 140 degrees in summer, pushing heat straight through an undersized or settled layer of insulation into the living space below. We measure existing depth and R-value with a thermal camera before quoting, so you know exactly what you have and what it will take to bring the attic up to a modern standard.
Get Attic QuoteRecycled paper fiber blown to perfect density, filling every cavity. Class A fire-rated, eco-friendly, and dramatically quieter than batts. Cellulose settles into irregular attic framing and around obstructions far better than pre-cut batts, so you get more consistent coverage without the gaps that let heat transfer through. It's treated with a borate fire retardant that also deters pests, and because it's dense-packed rather than loose-laid, it does a better job resisting wind-washing near soffit vents, a common weak point in South Florida attics.
Get Blown-In QuoteOld, wet, or rodent-contaminated insulation? We HEPA-vacuum it out, sanitize, and prep for a fresh install, often the same visit. Insulation that has been through a roof leak, hurricane intrusion, or rodent activity loses most of its R-value and can hold onto odor and allergens long after the original problem is fixed. We contain the work area, remove the compromised material with commercial HEPA vacuum equipment, treat the space for odor and pests where needed, and inspect the deck and framing underneath before anything new goes back in.
Get Removal QuoteLive near I-95, MIA, or a busy condo tower? Dense-pack cellulose and STC-rated assemblies cut sound transfer by 50 to 70%. We treat interior walls, floor/ceiling assemblies between units, and shared walls with condo neighbors, targeting the specific noise source, whether that's traffic, aircraft, an elevator shaft, or a neighbor's mechanical equipment. Combined with acoustic sealant at penetrations and outlets, dense-pack insulation closes the small air gaps that plain mass alone won't stop.
Get Soundproof QuoteWarehouses, restaurants, pole barns, tenant build-outs. Hurricane-code compliant, with thermal imaging verification on every project. Metal buildings in particular are prone to condensation on the underside of the roof panel without a proper vapor barrier and insulation system, which left untreated leads to dripping, rust, and mold on inventory below. We work around active business hours and tenant schedules, and every commercial job gets a post-install thermal scan so you have documentation of the finished R-value for your records or your landlord.
Get Commercial QuoteThe questions we hear most from Miami-Dade, Broward, and Boca Raton homeowners before their first insulation project.
The two biggest signs are an AC bill that feels high relative to your home's size and rooms upstairs that never quite cool down. Most South Florida attics built before the mid-2000s were insulated to a lower R-value standard than is recommended today, and insulation that has been through humidity cycles for a decade or more also settles and loses depth. A thermal-imaging inspection during your estimate shows the exact R-value you currently have, so the recommendation is based on a measurement rather than a guess.
Spray foam air-seals as it expands, closing gaps around framing and penetrations that cellulose can't reach, and closed-cell foam adds structural rigidity that matters for hurricane wind-load ratings. Cellulose is a lower-cost option that still performs well when dense-packed correctly, and it's often the better fit for an attic top-up where the roof deck and framing are already in good shape. Which one makes sense depends on the home's age, the existing insulation, and the budget, which is why we look at the space in person before recommending either one.
Most single-family attic and spray foam jobs are a single day from setup to cleanup, since our crews are foreman-led and dedicated to one job at a time rather than juggling multiple sites. Larger commercial and metal-building projects, or homes needing insulation removal first, can run one to three days depending on square footage and access. You'll get a realistic timeline in writing with your quote, not an estimate that changes once the crew shows up.
Yes. Qualifying insulation upgrades can be eligible for FPL and Duke Energy rebates as well as the federal Section 25C energy-efficiency tax credit, and the paperwork requirements change often enough that most homeowners don't want to deal with it themselves. We file the documentation as part of the project so you're not left tracking down invoices and specification sheets after the crew has already left.
Dense-pack cellulose and certain spray foam assemblies do reduce airborne sound transfer, which is why homeowners near I-95, Miami International Airport flight paths, or busy condo corridors ask about it specifically. The improvement depends on which walls or ceilings are treated and what the dominant noise source is, so we walk the space and identify where sound is actually entering before recommending a soundproofing package rather than a generic insulation upgrade.
We stop and tell you before covering anything up. Old or wet insulation sometimes hides roof leaks, rodent entry points, or early wood rot that needs to be addressed first, and installing new insulation over an unresolved problem just traps it out of sight. You'll get photos and a straightforward explanation of what we found and what it would take to fix, and the decision on how to proceed is always yours.
A look at recent insulation projects across Miami, Fort Lauderdale, and Boca Raton, the homes we left quieter, drier, and dramatically cheaper to cool.
2,400 sq ft · Closed-cell · FPL bill down $180/mo
This 1970s two-story had never been re-insulated. We removed the original degraded batts from the attic, closed-cell foamed the roof deck to bring the attic inside the thermal envelope, and sealed the rim joists in the crawlspace below, cutting the homeowner's summer FPL bill by roughly a third.
1,800 sq ft · Blown-in cellulose · Same-day install
The existing attic was sitting around R-19, well below the R-38 to R-49 range recommended for this climate. We added baffles at the eaves to preserve soffit airflow, then blew in enough cellulose to bring the whole attic up to R-49 in a single visit.
2BR · Dense-pack · Elevator shaft noise eliminated
The unit shared a wall with the building's elevator shaft, and the mechanical hum was audible in the primary bedroom at night. Dense-packing that shared wall cavity, combined with acoustic sealant around outlets and the door frame, brought the noise down to where it's no longer noticeable.
14,000 sq ft · Radiant barrier + spray foam
Metal roof condensation had been dripping onto stored inventory for years. We installed a radiant barrier system under the roof panels paired with spray foam at the perimeter, stopping the condensation and dropping interior temperatures enough that the warehouse's rooftop units now cycle far less often.

"Comfortable homes start in the walls. We treat insulation like the craft it is, one home at a time."
Insulation Co. of South Florida is a family-owned, in-house contractor serving Miami-Dade, Broward, and Boca Raton since 2012. Every project, from a $1,200 attic top-up to a $40,000 whole-home spray foam, is led by a foreman on our payroll, never subcontracted.
We've thermal-imaged over 2,300 homes in our region and know exactly where South Florida builders cut corners. That knowledge gets your AC bill down, the upstairs comfortable, and the humidity outside where it belongs.
South Florida presents a different set of challenges than most of the country: near-constant humidity, attic temperatures that regularly top 140 degrees in summer, and hurricane-code requirements that affect which insulation systems can even be installed on a roof deck. A crew trained on national averages will often recommend the same fiberglass batts and default R-values used in a much drier, milder climate, which is part of why so many homes here run hot upstairs no matter how hard the AC works. Our estimators and installers work exclusively in this region, so every recommendation accounts for the humidity, the storm season, and the specific way local homes were framed and built.
We're a small, owner-involved operation by design rather than a franchise or a lead-generation call center that dispatches whichever subcontractor is available that week. The person who scopes your project is the same company that stands behind the workmanship afterward, and our crews carry the tools, from thermal cameras to HEPA-filtered vacuum equipment, to diagnose a problem correctly the first time instead of guessing.

Homeowners often arrive with a single question, such as whether to add more material in the attic or whether the walls are the real problem. The honest answer usually starts with looking at what is already there. Our crew checks the type, depth, and condition of existing insulation, then looks at the attic floor, penetrations, and any places where air can move freely between the living space and the attic. Those details tell us far more than a general description of the house ever could. That is why we begin with observation and conversation rather than a standard recommendation. We write down what we find so you can see it too.
From there we talk through the options in plain terms. Blown-in material suits many open attic floors, spray foam can make sense in certain assemblies and tight spots, and wall work depends heavily on how the house was built. Each choice has tradeoffs in access, disruption, cleanup, and how the finished work is handled, and we explain those before anything begins. We also say so when a method is a poor fit for your situation, even if it is one we offer. The goal is a plan that matches the house you actually own, not a generic template applied to every address.
We would rather you understand the reasoning than simply agree to a package. If something you read online conflicts with what we recommend, ask about it. The scope and any quote are explained before work begins, so you can compare the plan to your own priorities and decide what fits your home and your schedule. A good decision is one you can explain to the next person who asks why the work was done the way it was. Questions are welcome at every step, and we are happy to repeat or clarify anything that is unclear. That is how we like to work with every customer.
A little preparation makes the day go smoother for everyone. Clear the path to the attic hatch, move stored items away from the opening, and make sure the hatch itself is reachable without a struggle. If the access point is in a closet or a garage, clear shelves and boxes so the crew can set up ladders and protect the area underneath. Tight hallways and cluttered closets slow a crew down and raise the chance of something getting bumped or scuffed. A few minutes of tidying beforehand can noticeably shorten the time the crew spends on setup. It also keeps the work area safer for the crew.
Think about the attic contents too. Stored boxes, holiday decorations, and old furniture sitting on the attic floor may need to be moved before material can go down. Tell us what is up there when you call, so we can plan time for it or suggest a way to handle it. Anything fragile or valuable is better relocated ahead of time, because attic temperatures and dust are hard on belongings that were never meant to be handled during a job. If you are unsure what counts as fragile, a quick call to us before the visit will sort it out, and we can suggest practical places to store things in the meantime. We will gladly talk it over.
On the day itself, expect equipment noise, hoses running through the house or along the exterior, and a crew moving in and out. Keep pets secured and let us know about any sensitivities to dust or odors. When the job wraps up, the crew reviews the finished work with you and cleans up the areas they used. If you notice anything you want to ask about afterward, call us and we will talk it through with you. Our aim is to leave your home in good order, with the work area cleaned and the attic hatch closed and secured the way we found it.
Tell us about your home. A real human will call back within 30 minutes during business hours, and you'll have a fixed written quote in your inbox within 24 hours.
