We run a 10-point inspection the industry skips, use local crews, quote same day, and back every seal with a lifetime workmanship warranty with FLIR proof reports.

Will spray foam lower my FPL bill?

Yes. Our sealed homes average a 37% cooling-cost reduction. Closed-cell foam plus a radiant barrier reflects up to 97% of radiant heat gain.

How fast can you inspect my home?

Same-week — usually within 3–5 days, often faster. Use the Schedule Inspection button to grab a real-time slot.

Do you work on new construction and existing homes?

Both. We engineer thermal packages for new builds and retrofit existing homes across Boca, Delray, and Boynton.

Is spray foam safe for Florida humidity and coastal homes?

Yes. Closed-cell foam acts as a moisture barrier and structural reinforcement, ideal for salt-air coastal environments.

Spray Foam Insulation for Fort Lauderdale Properties

spray foam insulation is the workhorse of Florida attic retrofits. For Fort Lauderdale properties, this is frequently the right specification — but we will tell you plainly when it is not, and when a less expensive approach delivers the same outcome.

Fort Lauderdale sits in South Florida, where the recommended attic target is R-38 to R-49. That number, along with where your ductwork runs and what condition the existing assembly is in, is what determines the right specification for your property.

Types and Methods

Closed-cell spray foam

The densest, highest-R-value insulation available — R-6.5 per inch. At 2 inches thick it qualifies as a Class II vapor retarder, blocking Florida humidity and moisture migration. It also increases wall and roof-deck racking strength by up to 250%, a real advantage in hurricane-zone construction.

Open-cell spray foam

Expands 100x on application, filling every cavity and crack for whole-home air sealing at a lower cost than closed-cell. It is breathable — letting moisture escape rather than trapping it — and excels at sound dampening, making it the choice for whole-attic coverage and interior walls.

Spray foam requires a clean, dry substrate. If we find roof leaks, water-damaged framing, or active mold, those get corrected first — foaming over moisture traps it permanently. We also verify ventilation paths are maintained or intentionally sealed per the engineered approach.

Benefits for Fort Lauderdale Property Owners

Airtight seal eliminates drafts and air leakage — fiberglass can't.
Closed-cell doubles as a moisture barrier for Florida humidity.
Adds structural strength to walls and roof decks.
Lasts the life of the home — no settling, no sagging.
Cuts cooling costs up to 40% in sealed South Florida attics.

Best Applications

Roof decks and conditioned attics
Coastal and waterfront walls needing a moisture barrier
Whole-home retrofits seeking maximum air sealing
Crawl spaces and rim joists
New construction aiming for IECC compliance

FAQs

Spray Foam Insulation FAQs — Fort Lauderdale

Most tri-city homes run $3,000–$9,500 depending on square footage, foam type, and scope. Closed-cell costs more per board foot but delivers higher R-value and a moisture barrier. Get an instant itemized quote by ZIP code.

Closed-cell (R-6.5/in) for moisture-heavy and structural applications — roof decks, crawl spaces, coastal walls. Open-cell (R-3.8/in) for expansive attic coverage and sound dampening where breathability matters. We spec both on most jobs.

Properly installed spray foam lasts the life of the home — 80+ years. It doesn't settle, sag, or degrade like fiberglass or cellulose. That's why we back it with a lifetime workmanship warranty.
