Impact Window Installation in Fort Myers, FL

Two newly installed hurricane impact windows on a Fort Myers home

Impact window installation is the foundation of what we do. A true impact window pairs laminated glass with an engineered aluminum, vinyl, or fiberglass frame, tested and rated as a complete assembly so it stays intact under sustained wind pressure and a windborne-debris impact — not just tough glass in an ordinary frame. For homes across Fort Myers and the rest of Lee County, that assembly has to carry a Florida Product Approval or Miami-Dade Notice of Acceptance rated to the design pressure required for that specific opening.

We install both new-construction and retrofit impact windows, on everything from a single replacement opening to a full-home package. Every job starts with measuring and calculating the required design pressure (DP) rating for each opening based on the home's height, roof exposure, and location, so the window you get is actually engineered for where it sits on the house — not a one-size-fits-all product.

Beyond storm protection, impact windows cut outside noise dramatically, block nearly all UV transmission that fades furniture and flooring, and improve energy efficiency because the laminated glass and tighter frame seals reduce heat transfer.

The Installation Process, Step by Step

We start with an on-site measurement of every opening and a DP calculation based on your home's height and wind exposure, then order the specific product for each opening rather than a single generic size. Once product arrives, our crew removes the old window down to the rough opening (or preps the existing frame for a retrofit insert), sets the new unit plumb and level, and fastens it per the manufacturer's engineered installation instructions — the exact fastener schedule and spacing that keeps the product's rating valid. We seal and flash the opening, apply structural sealant around the frame, and finish interior and exterior trim to match your home. The local building department then performs a final inspection to sign off the permit.

What's Actually in the Glass

Impact glass is laminated: two or more panes of glass bonded to an interlayer, typically PVB (polyvinyl butyral) or the stiffer SGP (SentryGlas Plus), under heat and pressure. When the outer pane cracks under debris impact, the interlayer holds the glass together and keeps the opening sealed instead of blowing out. SGP interlayers are stiffer and hold up better under larger sustained loads, which is why they show up more often on bigger openings and higher DP-rated products. We'll tell you which interlayer and glass makeup is specified for your particular openings and why.

Choosing a Frame Material

Aluminum frames are the most common choice in Southwest Florida because they hold up well structurally at larger sizes and higher DP ratings, resist warping in our heat and humidity, and typically cost less than the alternatives. Vinyl frames offer good energy efficiency and a lower price point but are generally limited on very large or high-pressure openings. Fiberglass sits at the premium end — dimensionally stable, low-maintenance, and strong — and is a common choice on coastal or high-end homes. We'll recommend the frame that fits your opening size, budget, and the look of your home.

Florida Building Code & Wind-Load Compliance in Lee County

Fort Myers and the rest of Lee County sit within a windborne-debris region under the Florida Building Code, which means most homes require impact-rated or shutter-protected openings rather than standard glass. The required design pressure isn't the same for every house — it's calculated from the building's mean roof height, its exposure category, and where the opening sits on the structure (corners and upper floors typically see higher loads). We calculate DP per opening and only install products carrying a current Florida Product Approval or Miami-Dade NOA that meets or exceeds it, and we submit that documentation with your permit application.

Signs Your Windows Need Replacing

If your home still has original single-pane aluminum windows, visible corrosion or pitting on the frames, condensation forming between panes on older double-glazed units, windows that won't latch or seal tightly, or you're currently putting up plywood or shutters before every storm watch, those are all signs it's time to move to impact glass. Rising energy bills and noticeable outside noise coming through closed windows are also common early indicators that the seals and glass have degraded past their useful life.

What Drives the Cost

Pricing depends on the number and size of openings, the DP rating required for each one, frame material, glass configuration, and whether it's a retrofit insert into an existing frame or a full-frame replacement down to the rough opening. Larger openings and higher-DP products cost more because they require heavier glass makeups and reinforced framing. We give you an itemized, per-opening quote up front so you can see exactly what's driving the total rather than one lump-sum number.

Insurance Premium Discounts

Florida insurance carriers use a wind mitigation inspection to credit specific storm-resistant features on a home, and impact-rated windows are one of the categories that inspection documents. Once your install passes final building-department inspection, a licensed wind mitigation inspector can verify the product ratings and generate the report your insurance agent needs to apply the credit. The size of the discount depends on your carrier and your home's other mitigation features, but it's worth pursuing on nearly every completed job.

Licensing, Insurance & Warranty

We hold active Florida contractor licensing and carry liability and workers' compensation insurance, and every product we install is backed by the manufacturer's warranty covering glass and hardware defects, plus our own workmanship warranty on the installation itself. Ask us for our license number and proof of insurance before you sign anything — a legitimate Florida contractor will hand it over without hesitation, and it matters for your permit application either way.

Impact Window Installation FAQs

Can I replace just one or two windows instead of the whole house?

Yes. Plenty of jobs start with a single opening — a bedroom that faces the worst afternoon sun, or a window that failed — and many homeowners phase a full-home upgrade over a year or two rather than doing it all at once. We'll quote exactly the openings you want done.

Do impact windows really block hurricane debris?

The products we install are tested to large-missile and small-missile impact standards required by the Florida Building Code for our wind zone, meaning they're rated to withstand a specific debris impact followed by sustained cyclic wind pressure without the opening failing.

Will new impact windows change how my house looks?

Not dramatically — impact windows come in the same style range as standard windows (single-hung, casement, picture, etc.) and in frame colors to match your home. Most homeowners and neighbors can't tell a home has impact windows just by looking at it from the street.
