Our core Cape Coral service is blown-in fiberglass attic insulation to R-49+ — the highest-ROI upgrade for any Lee County home. Every install includes air sealing of all attic penetrations, depth verification, preserved ventilation paths, and full site cleanup. Most Cape Coral homes are completed in a single day.
We also offer insulation removal for attics with old, settled, water-damaged, or pest-contaminated material; radiant barrier installation for homes with attic ductwork or dark roofs; and ventilation assessment and balancing to protect both your insulation and your roof.
For Cape Coral homeowners who want maximum cooling savings, we install a complete attic system: air sealing + blown-in fiberglass to R-49+ + radiant barrier (if applicable) + balanced ventilation. This system approach delivers 20–35% bill reduction — more than any single service alone.
Every Lee County project starts with a free attic assessment that measures your current R-value, identifies air leaks, checks ventilation, and recommends the right combination of services for your specific Cape Coral home.
We're blown-in specialists — not general contractors who occasionally insulate. That focus means Cape Coral homeowners get crews who've filled thousands of attics, calibrated equipment for consistent density, and a process refined across hundreds of Lee County homes.
Every Cape Coral service includes an itemized quote locked before work begins, premium materials, verified installation, and our 90-day performance guarantee. If your cooling bills don't drop as projected, we return and fix it.
