5.0 stars on Google. All from homes like yours.
Cardinal Insulation holds a 5.0-star rating on Google — and the largest share of them come from Boca Raton. This page rounds up what Boca homeowners actually say after a Cardinal install, neighborhood by neighborhood, so you can read reviews from streets you recognize instead of anonymous national testimonials.
Every review below is from a real Cardinal customer in a named Boca Raton community. We did not write them, edit them, or incentivize them. They are the words homeowners chose to leave after the crew left.
Royal Palm Yacht Club — "Cooling bill dropped 38%"
Daniel R., Royal Palm Yacht Club, Boca Raton ★★★★★
"Cardinal found heat leaks two other companies missed. The thermal report after install showed a sealed attic. Cooling bill dropped 38%."
Daniel's home is typical of the Royal Palm Yacht Club area — larger, two-story, with a master suite that baked every afternoon. Two other companies quoted a top-up. Cardinal ran a FLIR thermal inspection first, found the air leaks the top-up would have buried, and sealed them before insulating. The before-and-after infrared report is what closed the job, and the 38% FPL drop is what the review is about.
Boca Bridges — "The attic stays within 8° of the house"
Patricia S., Boca Bridges, Boca Raton ★★★★★
"We built new in Boca Bridges and Cardinal spec'd the insulation package before drywall. The attic stays within 8° of the house — our AC barely runs now."
New construction in Boca Bridges is where insulation decisions pay off for 30 years — or cost you for 30 years. Cardinal engineered the thermal package before drywall closed, which is the only point you can still do it right cheaply. The result Patricia describes — an attic within 8° of the living space — is what a properly air-sealed and insulated envelope looks like in a new Boca build.
Woodfield Country Club — "Second floor finally matches the ground floor"
Greg H., Woodfield Country Club, Boca Raton ★★★★★
"The crew sealed our Woodfield country-club home and the FLIR proof report showed every gap closed. Second floor finally matches the ground floor temperature."
The upstairs-downstairs temperature imbalance is the single most common complaint we hear in Boca's two-story country-club homes. It is almost never an AC problem — it is an envelope problem. Hot attic air was leaking past the second-floor ceiling through unsealed penetrations. Cardinal air-sealed the attic floor, added a radiant barrier, and brought the insulation to R-38. The FLIR proof report Greg mentions is the before-and-after infrared scan we run on every job.
What the reviews have in common
Read them again and three things repeat:
- A thermal inspection came first. Not a quote — a diagnosis. Every review mentions the FLIR scan or the thermal report. We image the attic before we touch it, and we image it again after. You see the data.
- Air sealing before insulation. The reviews describe sealed attics and closed gaps, not just "more insulation." That sequence is what separates a real upgrade from a cosmetic one.
- Measurable results. 38% off the cooling bill. An attic within 8° of the house. A second floor that matches the first. Not "more comfortable" — numbers.
Reviews from across our territory
Boca Raton is our home base, but the same pattern shows up in every city we serve — Delray Beach, Boynton Beach, Deerfield Beach, West Palm Beach, and Parkland. Local crews, local knowledge, and the same FLIR-first process. You can read neighborhood-specific reviews on each city page.
Why reviews matter for a local insulation company
In a service business, reviews are the whole reputation. A 5.0-star rating on Google is not a marketing claim — it is the cumulative verdict of the homeowners who let our crew into their home and then took the time to write about it. We earn every one, and we answer every one. If a job is not right, we come back. That is why the number keeps climbing and the average does not slip.

Marcus founded Cardinal Insulation after a decade of watching South Florida homes sealed the wrong way — fiberglass in coastal attics, no radiant barriers, no air sealing.
