Why Delray Beach homeowners pick Cardinal.
Delray Beach's climate and your insulation
Delray Beach sits in the hottest, most humid stretch of South Florida's Atlantic coast — 90°+ summers, 80%+ humidity, and an FPL bill that punishes any home with an under-insulated attic. The single highest-ROI upgrade for a Delray home is closed-cell spray foam to full R-value plus a radiant barrier, which drops attic temperatures 30–40°F and cuts cooling costs an average of 36%.
Delray's housing stock — and what each needs
Delray runs the gamut: 1920s bungalows in Pineapple Grove and Lake Ida with minimal original insulation, mid-century concrete-block homes in Tropic Isle and Berkshire Gardens, and beachfront condos along the intracoastal. We retrofit each with minimal-invasion techniques — preserving historic plaster on the bungalows, adding moisture-barrier closed-cell foam on the coastal condos, and restoring full attic R-value on the block homes.
The Delray insulation problem we fix most
The #1 issue in Delray attics is ductwork running through a 140°F space — your AC fights the attic before it ever reaches the living floor. We seal the attic with closed-cell foam (bringing it within 8° of living space), add a radiant barrier, and verify every seal with a post-install FLIR infrared report. The result: even temperatures upstairs and down, and an FPL bill that finally makes sense.
Why Delray homeowners choose Cardinal
We keep a dedicated Delray crew — not a crew driving down from West Palm — so inspections land on your calendar same-week, often within 3 days. Every install is backed by a lifetime workmanship warranty, documented with before-and-after FLIR thermal imaging, and rated 5.0★ on Google. No bird-named imitators, no national franchise call center — just local specialists who answer the phone.
