Impact window pricing in the Fort Myers area typically comes down to four things: window size and count, glass configuration, frame material, and how much structural work is needed around each opening. As a starting point, national market ranges (installed) look roughly like this:
| Type of work | Scope | Approximate price (installed) |
|---|---|---|
| Standard impact window (single unit) | per window, average size | $800 – $1,800 |
| Whole-home impact window package | 10-15 windows, single story | $9,000 – $22,000 |
| Impact sliding glass door | per unit | $2,000 – $5,500 |
| Impact entry door | per unit | $1,800 – $4,500 |
These are national ranges, not a quote for your home — the exact number for a Fort Myers property depends on a few things that don’t show up in generic pricing guides.
Every opening has to meet code, not just some. All of Lee County sits inside the Florida Building Code’s Wind-Borne Debris Region, with a design wind speed in the 150-180 mph range depending on the exact site. That means every exterior opening — not just the ones facing the street — needs impact-rated glazing or code-compliant shutters. If a contractor quotes you for “the front windows only,” ask specifically how the rest of the openings on the home will meet code; it changes the total project scope significantly.
Permits are part of the cost, not an add-on. Lee County requires a Windows/Doors/Shutters permit for replacement work, and each unit installed needs a Florida Product Approval number matching the property’s wind zone. A licensed local contractor typically folds permit handling into their quote — worth confirming it’s included before comparing prices between contractors.
Two things can offset the upfront number. Eligible homeowners may qualify for a My Safe Florida Home grant of up to $10,000 toward impact windows and doors (income and homestead requirements apply — see our My Safe Florida Home program page). Separately, once the work is complete and inspected, a fully impact-protected home may qualify for the largest single credit category on Florida’s wind mitigation insurance form — ask your contractor and your insurer how much that could reduce your annual premium.
Why comparing quotes matters here specifically. Because scope (how many openings, what glass rating, whether structural modification is needed) varies so much house to house in a market with strict code requirements, two contractors quoting the “same” project can land tens of thousands of dollars apart depending on what’s actually included. Comparing two or three quotes side by side is the most reliable way to see the real range for your specific home.
