Collectively they've earned 266 Google reviews at an average of 4.85★. Fort Myers is known as the gateway to Sanibel and Fort Myers Beach — strong rebuilding momentum after Hurricane Ian's 2022 direct hit on Lee County. It's still cheaper than Naples while sharing the same Paradise Coast weather — popular with retirees and remote workers. Climate here: tropical Gulf Coast — the warmest winters on the peninsula, dry season November through April, intense afternoon storms June through October. For insulation specifically, local homeowners plan around major Gulf hurricanes (Ian 2022 hit Lee + Charlotte counties hardest), king tide flooding, brackish water intrusion in older wells. Florida attics regularly hit 140°F in summer — and most homes built before 2010 have insulation rated for the wrong climate. The insulation companies below specialize in attic blow-in (R-30 to R-49), open and closed-cell spray foam, radiant barriers, knee-wall and crawlspace insulation, and full air sealing. Properly insulated FL homes cut AC bills 20–40% and last 5–8 years longer between system replacements.

What should I know about insulation specifically in Fort Myers?▾

For insulation, the biggest local factors are major Gulf hurricanes (Ian 2022 hit Lee + Charlotte counties hardest), king tide flooding, brackish water intrusion in older wells. Ask each pro how they handle these regional conditions before signing.
How much does attic insulation cost in Florida?▾
Blown-in fiberglass or cellulose to R-30 (typical 1,800 sq ft attic): $1,500–$2,800. Upgrade to R-38: add $500–$900. Open-cell spray foam: $4,500–$8,500. Closed-cell spray foam (best for FL): $6,500–$13,500. Radiant barrier installation: $1,200–$2,800. Most projects qualify for utility company rebates.
What R-value insulation does Florida need?▾
Florida (Zone 1-2) attic minimum is R-30; the IECC code recommendation is R-38, and best practice for new builds is R-49. Walls in new construction need R-13 to R-15. Below-grade and crawlspaces don't matter much in Florida. Investing in attic insulation is the single highest-ROI energy upgrade for FL homes.
Should I get spray foam in Florida?▾
Closed-cell spray foam is the gold standard for Florida — it acts as insulation + air seal + vapor barrier. Cuts AC load 30-50% in older homes. Open-cell is cheaper but lets moisture pass through (acceptable in Florida only with proper attic ventilation). Spray foam is overkill for newer homes already at code R-30+.
What's a radiant barrier and do I need one in Florida?▾
Radiant barriers are aluminum sheets stapled to roof rafters that reflect 95% of radiant heat — drops attic temps 20–30°F in Florida summers. ROI is 3–6 years on most homes. Best installed during roof replacement or in new construction. Existing-home retrofit costs $1,200–$2,800 for a typical attic.
Do insulation contractors need a license in Florida?▾
Florida requires a Specialty Insulation Contractor license for jobs over $2,500 or anything requiring permits. Always verify liability insurance, workers' comp, and (for spray foam) IAQ training. DIY blown-in is possible but inhalation risk and uneven coverage make it a bad call for most homeowners.
