Attic Insulation Fort Myers FL — Spray Foam, Blown-In & Batt Options (2026 Guide)

Why Fort Myers Homes Need Better Attic Insulation

If you live in Fort Myers or anywhere in Lee County, you already know — summer FPL bills are brutal. We're talking $300, $400, sometimes $500/month just to keep your house at 76 degrees.

Here's what most people don't realize: about 40% of that wasted energy is escaping right through your attic. The insulation that came with your house (especially if it was built before 2010) is probably compressed, settled, or just not enough for Florida heat.

We service Fort Myers, Lehigh Acres, Gateway, San Carlos Park, and all of Lee County — and we see the same story in almost every attic we inspect.

Your 3 Options for Attic Insulation in Fort Myers

1. Blown-In Fiberglass — Starting at $1.00/sq ft

This is the most popular choice for Fort Myers homeowners on a budget. We blow R-30 fiberglass insulation directly into your attic — it fills every gap, covers every joist, and gets your attic up to Florida building code.

For a typical 2,000 sq ft Fort Myers home, you're looking at around $2,000 for a full attic re-insulation. Most homeowners see their FPL bill drop 25-30% within the first billing cycle.

Best for: budget-conscious homeowners, older homes that just need a top-off, rental properties.

2. Open Cell Spray Foam — Starting at $0.40/board ft

Spray foam is a different animal. It doesn't just insulate — it air seals. That means no more hot attic air leaking into your living space through can lights, ductwork gaps, and ceiling penetrations.

Open cell is the more affordable spray foam option. At 3 inches of thickness on a 1,500 sq ft attic, you're in the $1,800 range. The R-value per inch is about 3.7, and it expands to fill every crack and crevice.

Best for: homeowners who want serious energy savings, homes with complex attic layouts, anyone tired of hot upstairs rooms.

3. Closed Cell Spray Foam — Starting at $1.00/board ft

This is the premium option — and honestly, it's what we recommend for most Fort Myers new construction and major renovations. Closed cell spray foam has an R-value of 6.5 per inch, acts as a vapor barrier, AND adds structural rigidity to your roof deck.

That last part matters during hurricane season. We've had customers ride out Cat 3 storms with zero roof damage because closed cell foam was essentially gluing their roof sheathing together.

For a 1,000 sq ft attic with 2 inches of closed cell on the roof deck, budget around $2,200.

Best for: new construction, hurricane hardening, homes with moisture issues, anyone who wants the best insulation money can buy.

FPL Rebates for Fort Myers Homeowners

Here's something a lot of Fort Myers homeowners miss: FPL offers rebates for insulation upgrades. We're an FPL Preferred Insulation Contractor, which means we know exactly which rebates apply to your project and we handle the paperwork.

Depending on your home and the work done, you could get up to $1,420 back in rebates. That can cover a huge chunk of a blown-in insulation job.

How to Know If Your Fort Myers Home Needs New Insulation

Here are the signs we see most often in Lee County:

• Your upstairs is always hotter than downstairs — classic sign of insufficient attic insulation
• FPL bills over $250/month — for a typical Fort Myers home, this usually means energy is escaping somewhere
• Your AC runs constantly — if it never cycles off, your house is leaking conditioned air
• You can see your attic joists — insulation should cover the joists completely. If you can see wood, you need more.
• Your home was built before 2010 — building codes have changed. Older homes rarely meet current standards.
