Live in Lee County? See our spray foam insulation service in Fort Myers for open- and closed-cell options and a written estimate.
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 electric utility 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.
Ready for a number on your own project? Scope, process and estimate requests are on our spray foam insulation in Fort Myers service page. This guide covers the reasoning behind those decisions.
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.
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:
Fiberglass performance depends on its condition, installation and air sealing. Properly installed spray foam can reduce air leakage, but neither foam type waterproofs the building or eliminates leaks, condensation and mold risk. Inspect and repair moisture problems before covering them.
Energy savings depend on the existing building, installation scope, HVAC operation, weather and occupancy. A fixed percentage, bill reduction or payback period cannot be promised from the insulation type alone.
Closed-cell foam has lower vapor permeance than open-cell foam. Select it for the actual assembly, available depth and moisture-control design. Structural or flood-performance claims require documentation for the selected product and approved assembly; a coastal address alone is not a specification.
For a roof-deck conversion, confirm the required insulation performance, thickness and moisture-control details for the approved assembly. Foam alone does not provide attic conditioning or humidity control.
Open-cell foam is vapor-permeable. Suitability at the roof deck or another surface depends on the assembly, available depth, product specifications and moisture-control design. Confirm the selected product’s R-value and installed thickness.

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.
Insulation is not a hurricane-protection system. Any claimed structural contribution must be documented for the exact product and assembly and accepted in the project design. It does not replace roof repairs, structural connections, opening protection or water-control details.
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.
The federal Section 25C credit does not apply to insulation placed in service after December 31, 2025. A new 2026 installation does not qualify. Read what changed for insulation tax credits in 2026.
Required insulation performance depends on the assembly and the project's approved code-compliance path. Confirm the requirements for each insulated surface:
Use the selected product's documented R-value at the specified installed thickness. Check available depth and coverage; the foam type alone does not establish code compliance.
Confirm any required thermal or ignition protection for the selected foam, assembly and use of the space. Product documentation, approved project details and applicable requirements determine the protection and inspection scope.

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.
Compare the proposed scope with your building’s current condition and energy-efficiency goals. No fixed savings or payback period is promised.
Material selection depends on the assembly and moisture-control design. Closed-cell foam has lower vapor permeance than open-cell foam, but neither product eliminates leaks, condensation or mold risk. Repair moisture problems before covering them.
Insulation is not a hurricane-protection system. Any claimed structural contribution must be documented for the exact product and assembly and accepted in the project design. It does not replace roof repairs, structural connections, opening protection or water-control details.
Plan to vacate during spray-foam application. Before work starts, obtain the selected manufacturer’s ventilation, curing, thorough cleaning, re-entry and re-occupancy instructions for the actual product and job conditions. Completion of spraying does not establish that the home is ready for occupants; there is no universal one-hour return time.
Existing insulation condition and the approved scope should guide the proposed work. The age of a home alone does not establish its potential energy savings.
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.
