Our Services
Insulation Built for Florida's Climate
Every service we offer is engineered around one reality: South Florida is one of the most demanding thermal environments in the country. We don't cut corners.
The gold standard for Florida attics
High-Density Blown Fiberglass
High-density blown fiberglass is our most-recommended solution for South Florida homes. Unlike batts or low-density alternatives, blown fiberglass conforms to every joist, gap, and irregular surface — creating a seamless thermal blanket with no voids or compression points.
Eco-friendly performance for older homes
Blown-In Cellulose Insulation
Blown-in cellulose is made from recycled paper fiber treated with fire retardants and borate compounds. It's an excellent choice for homeowners seeking an eco-friendly option or for older homes where fiberglass may not be the best fit. Cellulose fills irregular cavities exceptionally well.
The step most contractors skip
Meticulous Attic Air Sealing
Air sealing is the most critical — and most overlooked — step in any attic insulation project. Without sealing the bypasses first, even R-60 insulation will underperform. Hot, humid Florida air infiltrates through plumbing penetrations, electrical gaps, recessed light housings, and HVAC chases.
How It Works
Our Installation Process
Every Cardinal job follows the same proven sequence — no shortcuts.
Free Attic Assessment
We inspect your current insulation depth, R-value, air sealing condition, and any moisture or pest issues. You get an honest report — no upselling.
Air Sealing First
Before a single bag of insulation is opened, we seal every bypass we can find. This is non-negotiable on every Cardinal job.
Precision Installation
Material is blown to the exact depth required for your target R-value, verified with depth gauges placed across the attic floor.
Final Inspection & Documentation
We photograph the finished installation, document the R-value achieved, and provide paperwork for permits or future home sales.
Not Sure Which Service You Need?
Our free assessment tells you exactly what your attic needs — and what it doesn't. No pressure, no upsell.
