Insulation Removal & Sanitizing in Boca Raton, FL
Old, water-damaged, or rodent-contaminated insulation has to come out before new material goes in — and doing it wrong spreads fiberglass, mold spores, and allergens through your whole home. Cardinal removes attic and crawl space insulation under negative-pressure containment across Boca Raton, Delray Beach, Boynton Beach, West Palm Beach, and Parkland, then sanitizes the cavity so your new insulation starts clean.
Quick specs for Boca Raton.
Verified by a Building Scientist
Cardinal's insulation packages are specified and verified against building-science principles — not installed by guesswork. Every job carries a documented thermal proof report.
Building-Science Specified
Every insulation package is specified against building-science principles — conductive, convective, and radiant heat paths addressed in the correct order, not just more material.
FLIR Thermal Verification
A certified thermal-imaging protocol images the attic and ceiling plane before and after install. You see the documented proof the seal is real — not a claim.
R-Value & Depth Measured
Insulation depth is blown to land at the target R-value after settling, measured against Florida code and DOE guidance for IECC climate zone 2A — not estimated.
Specifications aligned with U.S. Department of Energy, ENERGY STAR®, and Florida Building Commission guidance for South Florida's hot-humid climate.
Installed to Florida code. Documented on every job.
Every Cardinal install in Boca Raton is specified to the Florida Building Code and IECC Climate Zone 2A requirements for hot-humid construction. We don't guess at R-value or skip air-sealing — we install to code, document it, and prove it with a FLIR thermal report.
R-30 ceiling insulation minimum
Florida Building Code, ResidentialThe Florida Building Code sets a minimum ceiling insulation value of R-30 for residential construction in South Florida. Cardinal installs to R-38 — above the code floor — and documents the installed depth with attic rulers and before/after photos on every job.
IECC Climate Zone 2A — hot-humid
International Energy Conservation Code · Zone 2ASouth Florida sits in IECC Climate Zone 2A, a hot-humid zone with specific insulation, air-sealing, and moisture-management requirements. Cardinal specs every package to Zone 2A guidance — closed-cell foam where moisture control matters, air-sealing before insulation, and ventilation pressure testing.
Air-leakage (blower door) limits
Florida Building Code — Air LeakageThe Florida Building Code limits air leakage in new residential construction, verified by blower-door testing. Cardinal air-seals top plates, penetrations, and the attic hatch before any insulation goes in — then proves the reduction with before-and-after blower-door readings when testing is scoped.
Permit & inspection compliance
Florida Building Code — PermitsWhere a permit is required, Cardinal pulls it and schedules the inspection. We install to code, document compliance, and hand you a depth-measurement and FLIR proof report so the inspector — and you — can verify the work before the balance is due.
Code-compliant by design. Cardinal installs to or above Florida Building Code minimums on every Boca Raton job — and hands you the documentation to prove it.
The numbers that matter.
Negative-pressure containment stops dust and spores from entering living space.
Truck-mounted vacuum removes fiberglass, cellulose, and debris to the bare cavity.
Sanitizing treatment kills mold, bacteria, and odor left by contamination.
Required before spray foam or blown-in retrofit on water-damaged attics.
Disposal handled — bagged, sealed, and hauled off-site per Florida code.
Why Boca Raton homes lose energy.
Six failures we find in nearly every Boca Raton attic we inspect — each one quietly draining your cooling budget.
Attic depth below target
Most pre-2010 South Florida homes sit at R-11 to R-19 against a DOE-recommended R-30 to R-60 for this climate zone.
Unsealed ceiling plane
Top plates, chases, can lights, and bath fans add up to the equivalent of an open window in your attic.
Leaky attic ductwork
The U.S. Department of Energy estimates typical systems lose 20 to 30 percent of conditioned air through leaks.
Blocked soffit vents
Previous insulation jobs installed without baffles choke off intake ventilation, trapping heat and moisture.
Uninsulated attic hatch
Nearly universal in existing homes — and a twenty-minute fix that pays back immediately in comfort.
Uninsulated block walls
West and south exposures on CBS homes radiate stored heat into living space well past sunset.

The questions Boca, Delray & Boynton actually ask.
Attic insulation removal across the corridor typically runs $1.50–$4.00 per square foot depending on material type, contamination level, and access. Heavily contaminated or rodent-damaged attics cost more due to sanitizing. Get an instant itemized quote by ZIP code.
If your existing insulation is water-damaged, compressed, moldy, or rodent-contaminated, yes — installing new material over it traps moisture and odor. Clean, dry, intact insulation can sometimes be topped up, but a free FLIR inspection tells you which you need.
Most single-family attics are cleared and sanitized in one day. Larger homes or heavily contaminated cavities can take two days. We contain the work area so your home stays livable throughout.
