Insulation in Fort Lauderdale, FL
Spray foam insulation in Fort Lauderdale is the dominant retrofit solution because most homes are 1950s-1970s concrete block (CBS) construction with unconditioned attics, and our 300-plus miles of canals push ambient moisture far higher than inland Broward. Most attic and wall jobs here run between $2,200 and $8,500, with closed-cell foam at the upper end because it’s the only material that resists the water vapor that saturates older fiberglass batts. Call (218) 261-7714 for a written price before any work starts.
Why Fort Lauderdale Homes Are Different
Fort Lauderdale runs on water. The canal system, more extensive than Venice’s, means a large share of residential lots in Lauderdale Isles, Rio Vista, and Tarpon River sit within yards of open water. That proximity drives relative humidity above 75% for most of the year and keeps a constant moisture load against building envelopes. In a 1960s CBS home with fiberglass batts in the attic, that moisture wicks upward, compresses the batts, and colonizes them with mold within a decade or two.
The housing stock compounds the problem. Homes built in Coral Ridge, Lauderdale Isles, and Rio Vista during the post-war boom have concrete block walls with no cavity insulation and attic spaces that routinely hit 150°F in summer. The insulation calculus here is inverted compared to northern climates: we’re rejecting radiant heat and blocking exterior moisture, not holding heat in. Vapor-open batt systems, the default in colder states, actively work against performance in Fort Lauderdale. A blower-door test on these homes often reads 4,000 CFM50 or higher before sealing, and half that after.
Our Main Fort Lauderdale Services
Two jobs dominate our Fort Lauderdale call volume: attic insulation retrofits in older CBS homes and crawl space encapsulation on canal-front lots. Each has a dedicated resource page below.
Attic Insulation in Fort Lauderdale
Most Fort Lauderdale attics in Rio Vista and Coral Ridge hold original 1960s fiberglass batts that have compressed to R-8 or worse under decades of humidity. We remove, air-seal the attic floor, and install blown-in fiberglass or closed-cell foam, with a blower-door reading before and after so you can see the performance change. The full scope, including removal, sealing, and new insulation, runs $2,200 to $6,800 on a typical 1,800 square foot CBS home. Details on Attic Insulation in Fort Lauderdale.
Crawl Space Encapsulation & Vapor Barrier in Fort Lauderdale
Canal-front homes in Lauderdale Isles and Tarpon River pull groundwater vapor into the crawl space year-round. We line the floor and walls with a vapor barrier, seal vents, and install a dehumidifier where the water table sits high, which stops rot and mold at the source. A full encapsulation on a 1,000 square foot crawl space here typically lands between $5,000 and $12,000. Read the full breakdown at Crawl Space Encapsulation & Vapor Barrier in Fort Lauderdale.

Spray Foam Insulation in Fort Lauderdale
Spray foam insulation in Fort Lauderdale answers the city’s specific problem: high humidity and 150°F attic temperatures that degrade fiberglass and let treated air escape through every top plate and can light. Closed-cell foam is the material of choice on canal-side CBS homes because it cures into a rigid, water-resistant layer that also adds structural strength. Spray Foam Insulation ranges from $2.50 to $7.00 per board foot installed depending on cavity depth and access.
Closed-Cell Spray Foam
Signs you need it
Your attic batts are damp to the touch, compressed, or show mold staining within two feet of the soffit.
What it costs in Fort Lauderdale
Closed-cell foam on a 1,500 square foot attic floor runs $6,500 to $13,500 in Fort Lauderdale, or $4.50 to $7.00 per board foot.
How we do it
We air-seal top plates and penetrations first, then spray closed-cell directly to the attic floor or roofline to the target R-value, flash the windows and doors, and run a blower-door test at the end.
Attic Roof Deck Foam
Signs you need it
Your attic is above the air conditioner’s heat load, your upstairs rooms run 8°F warmer than downstairs, or your HVAC ductwork sits in the attic.
What it costs in Fort Lauderdale
Roof deck spray foam in Fort Lauderdale runs $3.50 to $6.00 per board foot, or $8,000 to $16,000 for a standard 2,000 square foot attic.
How we do it
We seal the gable vents and soffits, spray a continuous thermal layer on the underside of the roof deck, and document the post-installation blower-door number so you can see the envelope change.
What Spray Foam Insulation Costs in Fort Lauderdale
| Item | Typical range in Fort Lauderdale |
|---|---|
| Closed-cell foam, attic floor (1,500 sq ft) | $6,500 - $13,500 |
| Roof deck spray foam (2,000 sq ft) | $8,000 - $16,000 |
| Rim joist spray foam (per 8 ft run) | $280 - $520 |
Is closed-cell worth the extra cost in Fort Lauderdale?
For canal-front CBS homes, yes. It’s the only insulation that doesn’t wick moisture from the air, and it stops conditioned air from leaving the envelope while adding racking strength. Call (218) 261-7714 for an exact quote.
How long does spray foam last in a Fort Lauderdale attic?
Closed-cell foam under a roof deck lasts 30 years or more here because it’s not exposed to UV or standing water. It doesn’t sag or compress the way fiberglass does and requires no maintenance. Estimates are free.
Blown-In Insulation in Fort Lauderdale
Blown-in insulation in Fort Lauderdale replaces compressed, moisture-degraded fiberglass batts in older CBS homes, typically in the same day. The material fills uneven attic floors and gaps around framing where batts leave voids, bringing an R-11 attic back to R-38 or better. Blown-In Insulation runs $1.20 to $3.00 per square foot installed, and we air-seal the floor first, every time.
Blown-In Fiberglass
Signs you need it
Your attic batts have compressed under their own weight and humidity to less than half their original depth, or sections are missing entirely.
What it costs in Fort Lauderdale
Blown-in fiberglass in Fort Lauderdale runs $1.20 to $2.20 per square foot installed, or $2,200 to $4,000 for a 1,500 square foot attic.
How we do it
We seal the attic floor penetrations, install a soffit ventilation path, then blow fiberglass to a consistent R-38 across the full floor, using a thermal camera to catch missed spots.
Blown-In Top-Up
Signs you need it
Your insulation is dry and intact but measures below R-30, or your electric bills have climbed year over year without a change in usage.
What it costs in Fort Lauderdale
A top-up over existing insulation runs $0.90 to $1.50 per square foot in Fort Lauderdale, or $1,400 to $2,400 on a 1,500 square foot attic.
How we do it
We measure the existing R-value, confirm the material is dry and mold-free, air-seal any exposed penetrations, then blow fiberglass over the top to bring the total to R-38.
What Blown-In Insulation Costs in Fort Lauderdale
| Item | Typical range in Fort Lauderdale |
|---|---|
| Full blown-in fiberglass (1,500 sq ft) | $2,200 - $4,000 |
| Blown-in top-up over existing | $1,400 - $2,400 |
| Dense-pack wall retrofit (per wall section) | $1,800 - $4,500 |
Can you blow insulation into existing walls?
Yes. Dense-pack fiberglass goes behind existing drywall through 2-inch holes, which works for the concrete block interior walls common in Lauderdale Isles. Call (218) 261-7714 for a written scope.
How much does blown-in insulation save on a Fort Lauderdale electric bill?
Most homeowners see a 20% to 30% cut in cooling costs after sealing and insulating, because the air conditioner stops running against a 150°F attic all day. We’ll show you the blower-door numbers.
Radiant Barrier Installation in Fort Lauderdale
Radiant barrier in Fort Lauderdale works by reflecting radiant heat back toward the roof before it can radiate into the living space below, which matters in a city where attics hold 140-160°F for five months straight. It’s often paired with air sealing and blown-in insulation on older CBS homes. Radiant Barrier Installation runs $0.90 to $2.50 per square foot of roof deck.
Attic Radiant Barrier
Signs you need it
Your attic gets so hot in summer that stored items warp, or your upstairs rooms won’t hold temperature below 80°F on a 95°F day.
What it costs in Fort Lauderdale
An attic radiant barrier in Fort Lauderdale runs $1,300 to $3,200 for a 1,500 square foot attic.
How we do it
We staple a double-sided foil barrier to the rafters, leaving a 1-inch air gap below the roof deck so heat reflects rather than conducts into the attic.
Radiant Barrier & Ventilation
Signs you need it
Your attic has soffit vents but no ridge vent, or you feel heat radiating down through the ceiling in the late afternoon.
What it costs in Fort Lauderdale
A radiant barrier plus ventilation correction runs $2,500 to $5,500 in Fort Lauderdale depending on ridge vent length and rafter runs.
How we do it
We install the foil barrier, check and correct soffit-to-ridge airflow, and document inlet and outlet vent areas so the attic isn’t trapping heat.
What Radiant Barrier Installation Costs in Fort Lauderdale
| Item | Typical range in Fort Lauderdale |
|---|---|
| Attic radiant barrier (1,500 sq ft) | $1,300 - $3,200 |
| Radiant barrier plus ventilation | $2,500 - $5,500 |
| Radiant barrier roof deck (per sq ft) | $0.90 - $2.50 |
Does radiant barrier help with Fort Lauderdale humidity?
No. It only blocks radiant heat, not moisture. Pair it with air sealing for any real humidity control. Get a written price at (218) 261-7714.
Is radiant barrier worth it in a Fort Lauderdale attic?
It’s worth it when the attic is the main heat source and you’ve already sealed the floor. On its own it helps by about 10-15°F in the attic, which lengthens HVAC life.
Insulation Removal & Replacement in Fort Lauderdale
Insulation removal in Fort Lauderdale is most common in the older CBS homes of Lauderdale Isles, Rio Vista, and Coral Ridge where 1960s fiberglass batts have been absorbing canal moisture for 50 years and never fully dry. We tear out the old material, sanitize the attic, seal the floor, and put back the right insulation for a humid climate. Insulation Removal & Replacement runs $1,500 to $5,500 before new material goes in.
Contaminated Insulation Removal
Signs you need it
Your attic insulation tests positive for mold, or you can see rodent droppings, stains, and matted-down tunnels through the material.
What it costs in Fort Lauderdale
Contaminated insulation removal in Fort Lauderdale runs $2,800 to $6,000 for a 1,500 square foot attic, including HEPA vacuuming and sanitizing.
How we do it
We bag and remove the contaminated material through a sealed chute, HEPA-vacuum the attic floor, apply an antimicrobial treatment, and leave a photo record of the result.
Attic Insulation Replacement
Signs you need it
Your existing insulation is compressed, wet, or deteriorated to the point that topping it up would just bury a problem.
What it costs in Fort Lauderdale
Full removal and new blown-in fiberglass runs $3,800 to $9,000 in Fort Lauderdale depending on attic size and access.
How we do it
We remove the old material, air-seal the attic floor, check the ventilation path, then blow new fiberglass to R-38 or spray closed-cell foam as specified.
What Insulation Removal & Replacement Costs in Fort Lauderdale
| Item | Typical range in Fort Lauderdale |
|---|---|
| Contaminated insulation removal | $2,800 - $6,000 |
| Full removal plus new blown-in | $3,800 - $9,000 |
| Attic restoration after removal | $1,500 - $4,500 |
Do I need to remove old insulation before adding new in Fort Lauderdale?
Only if it’s wet, moldy, or rodent-damaged. Dry, intact insulation can be topped up. We’ll inspect and tell you if removal is unnecessary, with photos. Call (218) 261-7714.
How long does insulation removal take?
A full tear-out and replacement on a 1,500 square foot Fort Lauderdale attic takes one to two days. We handle the disposal and leave a written record of what left the house.
Attic Air Sealing in Fort Lauderdale
Attic air sealing in Fort Lauderdale stops conditioned air from escaping through top plates, can lights, and wall penetrations before any insulation goes in. That’s the order we always work: seal first, then insulate, because insulation over an unsealed attic is just a filter. Attic Air Sealing runs $1,200 to $3,500 on a typical CBS home.
Attic Floor Air Sealing
Signs you need it
Your blower-door test reads above 3,000 CFM50, or you can see daylight coming through the attic floor around wires and plumbing.
What it costs in Fort Lauderdale
Attic floor air sealing in Fort Lauderdale runs $1,200 to $2,800 for a 1,500 square foot attic.
How we do it
We seal every seam, short wall, and penetration in the attic floor with closed-cell foam or mastic before any insulation is installed.
Can Light & Duct Boot Sealing
Signs you need it
Your ceiling feels warm around can lights, or your home is dusty no matter how often you change the filter.
What it costs in Fort Lauderdale
Can light and duct boot sealing runs $500 to $1,500 in Fort Lauderdale depending on the number of fixtures.
How we do it
We install sealed, fire-rated covers over can lights and seal every duct boot to the drywall with mastic so the attic air stays out of the conditioned space.
What Attic Air Sealing Costs in Fort Lauderdale
| Item | Typical range in Fort Lauderdale |
|---|---|
| Attic floor air sealing | $1,200 - $2,800 |
| Can light and duct boot sealing | $500 - $1,500 |
| Full attic air sealing package | $1,600 - $4,000 |
Can I do attic air sealing in Fort Lauderdale myself?
You can, but the risk is you’ll miss the leakiest spots, and working in a 150°F attic is dangerous. A pro with a blower-door setup will find what you can’t. Estimates are free.
How much does air sealing reduce my electric bill?
Most Fort Lauderdale homeowners see a 10% to 20% reduction after sealing, because the AC stops pulling in humid attic air. We’ll give you a before-and-after blower-door reading.
Wall Insulation in Fort Lauderdale
Wall insulation in Fort Lauderdale targets concrete block homes with no cavity insulation, which is most of the CBS housing stock built in the 1950s through 1970s. Injection and drill-and-fill methods put insulation inside the block cores without tearing out drywall. Wall Insulation runs $1,800 to $6,500 per wall section depending on method and access.
Injection Foam Wall Insulation
Signs you need it
Your interior walls radiate heat in the afternoon, or your AC runs nonstop even with a properly insulated attic.
What it costs in Fort Lauderdale
Injection foam into block wall cores runs $2,500 to $6,500 per wall section in Fort Lauderdale.
How we do it
We drill small holes into the block cores from inside or outside, inject slow-rise foam, seal each hole, and document the work.
Interior Wall Soundproofing
Signs you need it
You can hear traffic, neighbors, or plumbing through interior walls, or your bedroom shares a wall with a noisy living space.
What it costs in Fort Lauderdale
Interior wall soundproofing with dense insulation runs $1,200 to $3,800 per wall in Fort Lauderdale.
How we do it
We dense-pack fiberglass or blow-in cellulose into the wall cavity and seal around outlets, adding foam gaskets to cut sound transfer.
What Wall Insulation Costs in Fort Lauderdale
| Item | Typical range in Fort Lauderdale |
|---|---|
| Injection foam wall retrofit (per wall) | $2,500 - $6,500 |
| Drill-and-fill block wall (per wall section) | $1,800 - $4,500 |
| Interior wall soundproofing (per wall) | $1,200 - $3,800 |
Can you insulate concrete block walls from the outside?
Yes, but in Fort Lauderdale’s humid climate, we typically insulate from the inside to avoid trapping moisture in the block. A written price comes first, always.
How much does wall insulation help with cooling costs?
Wall insulation alone typically cuts cooling costs 10% to 15% in Fort Lauderdale because it blocks heat gain through the block cores. Call (218) 261-7714 for specifics.
Attic Cleaning & Rodent Proofing in Fort Lauderdale
Attic cleaning and rodent proofing in Fort Lauderdale deals with the overlap of humid, aging attics and the rats that enter through soffit gaps in older CBS homes. We remove the contamination, sanitize the space, and seal the entry points so the problem doesn’t return. Attic Cleaning & Rodent Proofing runs $800 to $4,000 depending on attic size and level of contamination.
Attic Cleanout
Signs you need it
You can see rodent droppings, nesting material, or stained insulation in the attic, or your home smells musty near the ceiling.
What it costs in Fort Lauderdale
An attic cleanout in Fort Lauderdale runs $900 to $2,500 for a 1,500 square foot attic.
How we do it
We bag and remove contaminated insulation, HEPA-vacuum the floor, and document the whole process with photos before and after.
Rodent Proofing & Exclusion
Signs you need it
You hear scratching in the walls at night or see droppings reappear within days of cleaning.
What it costs in Fort Lauderdale
Rodent exclusion and soffit sealing runs $1,200 to $3,500 in Fort Lauderdale depending on the number of entry points.
How we do it
We seal every gap larger than a pencil with steel mesh and foam, install exclusion devices where needed, and leave a written report of every entry point closed.
What Attic Cleaning & Rodent Proofing Costs in Fort Lauderdale
| Item | Typical range in Fort Lauderdale |
|---|---|
| Attic cleanout (1,500 sq ft) | $900 - $2,500 |
| Rodent proofing and exclusion | $1,200 - $3,500 |
| Attic sanitizing and decontamination | $800 - $1,800 |
How fast can you get rats out of a Fort Lauderdale attic?
Usually within one to two visits. We seal the entry points and set exclusion devices, so the rats leave and can’t come back. Call (218) 261-7714 for a written plan.
Does attic cleaning include new insulation?
No, but we’ll inspect after cleaning and tell you what’s needed. If the insulation is compromised, we’ll quote replacement separately with a written scope.
Home Energy Audit in Fort Lauderdale
