Fort Myers homeowners face the same brutal reality as the rest of Southwest Florida: your attic hits 150°F+ by noon, your AC runs all day, and FPL sends you a bill that makes you wince every month. The difference between Fort Myers and most other markets? You have fewer insulation contractors to choose from — and some of them showed up last year with a truck and a YouTube education.
Ideal Insulation has been serving Fort Myers and all of Lee County since 2013. We're based in Naples — 30 minutes south — with 9 spray rigs that run throughout Lee County daily. We're an FPL Preferred Contractor, which means Florida Power & Light has vetted our work quality and stands behind our installations.
Fort Myers sits in IECC Climate Zone 1 — the hottest and most humid zone in the country. If you're comparing Fort Myers to, say, Atlanta or Charlotte, the insulation game is completely different here. Humidity is the silent killer.
Lee County averages 75-85% relative humidity year-round. Traditional fiberglass batts are air-permeable — moisture moves right through them. In Fort Myers attics, we routinely find fiberglass that's:
This isn't a failure of the product — it's a failure to use the right product for this climate. Spray foam doesn't absorb moisture, doesn't sag, and creates an air seal that prevents humid air from entering your building envelope in the first place.
The average Fort Myers home spends thousands per year on electricity, with cooling accounting for 50-60% of that cost. Spray foam insulation typically reduces cooling costs by 30-40% — and on a typical residential spray foam investment, most homeowners see a 2-5 year payback. The foam itself lasts 50+ years.
Our top recommendation for Fort Myers attics and exterior walls. R-6.5 per inch, doubles as a vapor barrier, adds structural strength to your roof deck. It's the premium option — and the one that delivers the biggest energy savings. Closed cell is especially important for Fort Myers properties in flood zones near the Caloosahatchee River and Fort Myers Beach, where it serves double duty as a moisture barrier.
For an unvented attic conversion (spraying the roof deck instead of the attic floor), Florida Building Code allows R-20 in Climate Zone 1, which closed cell achieves in just 3 inches. This is the gold standard installation for Fort Myers homes.
Open cell is the budget-friendly spray foam option with excellent sound dampening and R-3.7 per inch. Best for interior walls, large attic floors, and projects where overall value is the priority. Not a vapor barrier, so we don't recommend it for crawl spaces or areas with direct moisture exposure.

Our Fort Myers crews handle every type of residential and light commercial installation:
Common Fort Myers home styles we insulate include CBS block construction, frame stucco, and manufactured homes — each with different installation approaches that our 13 years of local experience has dialed in.
Our crews work throughout Lee County every day:
Hurricane Ian devastated parts of Fort Myers in September 2022. Three years later, many homes are still being rebuilt or extensively renovated. If you're rebuilding, this is your one chance to do insulation right.
New construction and major renovations are the perfect time for spray foam because walls are open and attic decks are accessible. The cost is significantly lower during construction (no need to remove existing insulation or work around finished surfaces), and the energy savings start from day one.
Closed cell spray foam adds wind uplift resistance to your roof deck — FEMA research shows spray-foamed roofs perform significantly better in hurricanes. After what Fort Myers went through with Ian, that's not a luxury — it's common sense. Many Fort Myers homeowners who rebuilt with spray foam after Ian report noticeably lower energy bills and better comfort than their pre-storm homes.
Every Fort Myers project is different — attic size, accessibility, existing insulation removal, and foam type all affect the final number. Here's what to expect:
We provide free estimates with thermal camera scans included — no obligation, no high-pressure sales tactics. The thermal scan alone shows you exactly where your home is losing energy, so you can make an informed decision.
Fort Myers is in FPL's service territory, which means you may qualify for utility rebates on qualifying insulation upgrades. As an FPL Preferred Contractor, we know the program inside and out and handle the rebate paperwork as part of your project.
On top of that, the federal 25C energy efficiency tax credit allows homeowners to claim up to $1,200 for qualifying insulation improvements. That's real money back at tax time. Read our full guide to the 2026 insulation tax credit for details on how to qualify.
Fort Myers falls in IECC Climate Zone 1, which means the following R-value minimums apply:
Spray foam meets or exceeds all of these requirements — closed cell hits R-30 in about 4.5 inches, and open cell gets there in about 8 inches. Both are well within standard attic and wall cavity depths.
Fire barrier requirements also apply: thermal barriers (typically drywall) in living spaces, ignition barriers in attics and crawl spaces. Every Ideal Insulation project is installed to pass Lee County building inspection the first time.

Spray foam insulation costs in Fort Myers depend on the type of foam (open cell vs closed cell), the area being insulated, and accessibility. Open cell is the more affordable option while closed cell costs roughly 2-2.5x more but delivers higher performance. Most residential projects range from a few thousand dollars for a single area up to larger investments for whole-home upgrades. Call (239) 455-2002 for a free estimate with thermal scan included.
Yes. Fort Myers sits in the hottest, most humid climate zone in the country (IECC Zone 1), where cooling costs account for 50-60% of your electric bill. Spray foam typically reduces cooling costs by 30-40%, and most homeowners see a full return on investment within 2-5 years. The foam lasts 50+ years, so the savings continue long after the payback period.
Closed cell spray foam is the best insulation for Fort Myers humidity. It creates an air-tight seal that blocks moisture vapor infiltration and does not absorb water. In a climate with 75-85% average humidity, traditional fiberglass batts sag, compress, and grow mold. Spray foam eliminates these issues entirely. Open cell spray foam also resists humidity better than fiberglass but is not a vapor barrier on its own.
Yes. Closed cell spray foam adds structural rigidity and wind uplift resistance to your roof deck. FEMA research confirms that spray-foamed roof decks perform significantly better in high winds. After Hurricane Ian devastated Fort Myers in 2022, many homeowners rebuilding chose closed cell spray foam specifically for this added hurricane protection.
Fort Myers is in FPL's service territory, and qualifying insulation upgrades may be eligible for FPL rebates. As an FPL Preferred Contractor, Ideal Insulation handles the rebate application paperwork as part of your project. You may also qualify for up to $1,200 in federal 25C energy efficiency tax credits on top of any utility rebates.
Most residential spray foam projects in Fort Myers take 4-8 hours, completed in a single day. You can stay home during the work. We ask that you stay out of the spray area during application and for about an hour after for ventilation.
Especially for older homes. Pre-2002 construction in Fort Myers often has R-13 or less in the attic — well below current code (R-30). Upgrading with spray foam delivers the biggest percentage improvement in comfort and energy savings. Many older Fort Myers homes see 35-45% reductions in cooling costs after spray foam installation.
Yes. Lehigh Acres is one of our highest-demand areas in Lee County. Many Lehigh homes were built with minimal insulation and benefit enormously from spray foam upgrades. Our crews are in Lehigh multiple times per week.
