Who writes a Cardinal Insulation quote | Cardinal

BPI is the Building Performance Institute. The card means Russell has passed their testing for building-performance work, including how a house leaks air and how the ceiling, the ducts, and the attic relate. Ask to see the card at the estimate. We do not print a certificate number on this site. If you want the number, ask him for it in person and check it with BPI.

The card is not a roofing license, a pest-control license, or a mold-remediation license. If animals are still in the attic, a licensed pest company gets them out. If the rooms below have a mold problem, that is a remediator. We remove insulation that is wet, moldy, or full of nests, and we can treat the bare deck after that removal. We do not call that mold remediation for the house.

A blower door is a fan set in an exterior door. It pulls the house to 50 pascals and the gauge reports air changes per hour at that pressure. Florida's 2023 energy code, Section R402.4.1.2, limits a new house in climate zones 1 and 2 to 7 air changes per hour, tested to ANSI/RESNET/ICC 380. Palm Beach County is climate zone 1A. That limit is for the test. It is not a bag of insulation.

Most of the attics we touch are existing houses. Adding insulation over dry fill is a small share of the thermal envelope. The code section that requires the test on new houses does not turn every top-up into a blower door. Russell is certified to run the test. The ACH50 number goes on the paperwork only when the fan was set in the door and the gauge was read. An insulation price is not that test. If someone hands you 7.0 on a proposal and no one set up a fan, the number was typed, not measured.

The first question is the attic you have. A vented ceiling gets an air seal, then blown-in to an even R-38. The 2023 Florida code floor for this climate is R-30, Table R402.1.2. R-49 and R-60 are a colder map. New fiberglass is about R-2.5 per inch. Four inches of settled fiberglass already in the house is about R-9. The new layer closes the gap. It is not 15 new inches piled on a full attic.

Dry fill stays. Wet fill, mold on the insulation, and nests come out first, at their own price. Sanitizing the bare deck is a second price. The blow is a third. Spray foam is a roof deck or a bonus room, and only after the vents over that roof are closed. Two inches of closed-cell foam is about R-13. It is not the attic-floor job. A planning range for about 1,800 square feet with 4 inches of settled fiberglass, brought to R-38 in new fiberglass, is about $2,100 to $3,350. The range is not the quote. The quote is the attic he saw.

Quality Business Awards listed Cardinal Insulation as Best Insulation Contractor in Boca Raton, Florida, for 2026. That is their listing. It is not a state license, and it is not a claim that every other company skips the work. It does not apply itself to Delray Beach, Boynton Beach, or Jupiter. The check you can make on a finished attic is the depth marker, the open baffle, and whether the hatch was sealed.

There is no second Boca pin in West Boca. Boynton Beach has no street address on this site. The walk-in for Boynton is the Delray shop. Jupiter is Cardinal Insulation of Jupiter, its own phone, not this 561 number.

Ask to see the BPI card. Ask whether a blower door is included. If it is not, the proposal should not show an air-changes number. Ask which fill stays and which comes out. Ask for the depth in inches, not only an R-value. Ask that the soffit stay open, with at least the 1-inch space in Section R806.3. Depth markers, at least one every 300 square feet, should face the hatch when the crew leaves.
