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.

Air Sealing in Palm City, Florida

Insulation slows heat — air sealing stops the leaks that carry it. Every Boca Raton, Delray Beach, Boynton Beach, West Palm Beach, and Parkland home leaks conditioned air through gaps around plumbing, wiring, recessed lights, attic hatches, and top plates. Cardinal finds and seals every leak with blower-door-guided air sealing, then proves the reduction with before-and-after readings. It's the single highest-ROI upgrade you can make before adding insulation.

Air Sealing for Palm City Properties

air sealing is the workhorse of Florida attic retrofits. For Palm City 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.

Palm City 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.

Air Sealing at a glance

R-value: Measured in ACH (air changes per hour) — no R-value
Installed cost: $600 – $2,500 installed
Service life: Permanent (foam and caulk do not degrade)
Available in: Palm City and throughout the surrounding area

Types and Methods

Blower-door-guided air sealing

We pressurize your home with a blower door, locate every leak with a smoke pencil and FLIR camera, then seal them with foam and caulk. The blower door measures the before-and-after in ACH — so you know exactly how much leakage we eliminated.

Attic-specific air sealing

Targeted sealing of the attic floor — top plates, can lights, plumbing and wiring penetrations, chases, and the attic hatch. This stops conditioned air from escaping into the attic and is the highest-ROI upgrade before adding insulation.

Air sealing should always come before insulation, not after. Insulation filters air — it doesn't block it. Sealing the leaks first, then insulating, delivers the full rated R-value. Doing it in reverse traps air in the insulation and wastes the performance.

Benefits for Palm City Property Owners

Stops conditioned air from escaping through gaps insulation can't reach.
Lowers cooling bills up to 20% on its own — before any insulation is added.
Reduces humidity and dust intrusion for cleaner indoor air.
Improves HVAC performance — your system runs less and lasts longer.
Verified with blower-door testing — you see the before-and-after numbers.

Best Applications

Homes with high FPL bills and uneven temperatures
Pre-insulation prep — seal before you insulate
Drafty homes with cold or hot spots
Homes with dust, humidity, or odor intrusion
Energy code compliance and rebate programs

Yes — insulation doesn't stop air leaks. Fiberglass and cellulose filter air; they don't block it. Gaps around wiring, plumbing, and top plates let your conditioned air escape. We seal those leaks first, then insulate — doing it in reverse traps air in the insulation and wastes the R-value.

Insulation resists heat transfer through a material; air sealing stops the actual movement of air in and out of your home. Both are needed. We use blower-door testing to find the leaks, seal them with foam and caulk, then measure the improvement — so you know exactly how much leakage we eliminated.
