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.
