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.

Blower Door Testing in Fort Lauderdale, Florida

A blower door test pressurizes your home and measures exactly how much conditioned air is escaping through gaps insulation can't reach. Cardinal runs blower-door-guided air sealing across Boca Raton, Delray Beach, Boynton Beach, West Palm Beach, and Parkland — finding the leaks, sealing them, and proving the reduction with before-and-after readings. It's the diagnostic that turns a guess into a number.

Blower Door Testing for Fort Lauderdale Properties

blower door testing 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

Pre-retrofit blower door test

A baseline test before any air sealing or insulation work. It pressurizes your home and measures exactly how much conditioned air is escaping through gaps in the envelope. The result — expressed in ACH — tells you whether air sealing will pay off and by how much.

Post-retrofit verification test

A second test after air sealing or insulation is complete, proving the improvement. We compare the before-and-after ACH readings so you see exactly how much leakage we eliminated — a number, not a guess.

A blower door test requires all exterior doors and windows closed, and all combustion appliances off. We schedule the test when the home is unoccupied and the HVAC system can be shut down for the duration — typically 1–2 hours.

Benefits for Fort Lauderdale Property Owners

FAQs

Blower Door Testing FAQs — Fort Lauderdale

A blower door is a calibrated fan sealed into an exterior door frame. It pressurizes (or depressurizes) your home and measures how much air leaks out through gaps in the envelope. The result is expressed in ACH — air changes per hour — the single most useful number for understanding how leaky your home is and whether air sealing will pay off.

A standalone blower door test across the corridor runs $250–$500. It's included at no charge with every Cardinal air-sealing or insulation package, and we credit the standalone fee toward any install you book. Get an instant itemized quote by ZIP code.

If your home is older or has never been air-sealed, yes. The test finds the leaks insulation can't reach — around wiring, plumbing, recessed lights, and the attic hatch — so they get sealed before insulation goes in. Doing it in reverse traps air in the insulation and wastes the R-value.

Florida Building Code targets 5–7 ACH50 for new construction. Older homes often test at 10–15 ACH50 or higher. After Cardinal air sealing, most homes land at 4–6 ACH50 — a measurable, documented improvement you can see in the before-and-after readings.
