How much does spray foam insulation cost in Boca Raton?

Most Boca Raton homes run $3,500–$9,500 depending on square footage and scope. We give an itemized instant quote by ZIP code, and most homeowners recover the cost in 3–5 years on cooling savings.

Which areas does Cardinal Insulation serve?

We serve Boca Raton, Delray Beach, and Boynton Beach, FL — the entire tri-city corridor from the Boca inlet to Boynton's western estates.

How is Cardinal different from other insulation companies?

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.

Duct Insulation and Sealing in Hollywood, Florida

The U.S. Department of Energy estimates that 20–30% of the air moving through a typical home's ductwork is lost to leaks and poor insulation. In a South Florida attic running 140°F, uninsulated or leaky ducts mean your AC is fighting a losing battle. Cardinal seals every joint with mastic, wraps ducts to R-8, and verifies the improvement with before-and-after readings — recovering the cooled air you already paid for.

Duct Insulation and Sealing for Hollywood Properties

duct insulation and sealing is the workhorse of Florida attic retrofits. For Hollywood 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.

Hollywood 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

Mastic duct sealing

Every joint and seam in the ductwork is sealed with fiber-reinforced mastic — a permanent sealant that hardens and flexes with thermal expansion. Unlike duct tape, which fails within months under attic temperatures, mastic lasts the life of the ductwork.

R-8 duct wrap insulation

Ductwork is wrapped in R-8 fiberglass insulation with a reflective vapor barrier, reducing heat gain through the duct walls in 140°F attics. This keeps the cooled air cooler as it travels from the AC to your living space.

The U.S. Department of Energy estimates 20–30% of conditioned air is lost through duct leaks. In a 140°F South Florida attic, uninsulated ducts also gain heat — so the air that does arrive is warmer. Sealing and insulating ducts recovers both losses.

Benefits for Hollywood Property Owners

Recovers 20–30% of cooled air lost through duct leaks (U.S. DOE estimate).
Mastic-sealed joints stop air leakage permanently — tape fails, mastic doesn't.
R-8 duct wrap reduces heat gain through ductwork in 140°F attics.
Lowers AC runtime and extends equipment lifespan.
Verified with before-and-after airflow readings — you see the improvement.

Best Applications

Homes with ductwork in the attic
High FPL bills with uneven room temperatures
Duct systems over 10 years old with original tape seals
Rooms that never cool properly despite adequate AC
Post-duct-cleaning sanitizing and resealing

FAQs

Duct Insulation and Sealing FAQs — Hollywood

Duct sealing and insulation runs $800–$3,500 depending on duct length, accessibility, and whether the ducts are already insulated. Mastic sealing alone is on the low end; full sealing plus R-8 wrap is on the high end. Get an instant itemized quote by ZIP code.

Duct tape fails within months under attic temperatures — the adhesive dries out and the tape falls off. Mastic is a fiber-reinforced sealant that hardens permanently, flexes with thermal expansion, and lasts the life of the ductwork. We seal every joint with mastic, not tape.
