Fast, Reliable Impact Windows & Doors Across Stock Island
Impact windows and doors on Stock Island are not an upgrade you shop around for casually. Monroe County code essentially requires impact-rated openings on nearly every structure here, and the salt air corrodes standard frames and hardware faster than anywhere on the Florida mainland. If you own a home on Stock Island, the question is not whether you’ll replace your windows, it’s when and how you’ll pay for it. TruePane Windows & Doors handles the full scope: Hurricane Impact Windows, Impact Entry & French Doors, Impact Sliding Glass Doors, and the wind mitigation paperwork that comes with them. Call (954) 280-4413 for a free estimate, and we’ll walk you through what your home actually needs.
Why TruePane Windows & Doors Is Stock Island’s Preferred Impact Windows & Doors Company
Dale Kessler founded TruePane in 2008 on a rule that still hangs on the whiteboard in the shop: if the pane is not true, the job is not done. That’s the standard we bring to every Stock Island job, whether it’s a single jalousie replacement on a 1970s CBS home off Maloney Avenue or a full opening package on a new elevated stilt house near the water. We’re not a franchise operation with rotating crews. Our technicians are background-checked, uniformed, and trained in marine-grade installation practices specific to Monroe County’s wind exposure zone.
Stock Island homeowners tell us the same thing over and over: they’ve been burned by a contractor who didn’t understand local code or used mainland-spec hardware that failed in five years. That’s why we quote manufacturer lines side by side on paper, register both warranty layers before the truck leaves the driveway, and back every job with our Done Right Promise. If it’s not done right, we make it right. No paperwork fights, no arguing. A live person answers our phone 24/7, and we’ve been serving Stock Island since 2008 through the Kessler family’s glazier tradition. Senior and veteran homeowners get a permanent 5% discount on every job.
Our Impact Windows & Doors Services in Stock Island
Hurricane Impact Windows
Stock Island sits in Monroe County’s extreme wind exposure zone, where design wind speeds exceed 150 mph. That means single-hung, double-hung, casement, and fixed impact windows all need to carry a Florida Product Approval and meet the county’s current wind code. We install impact windows from PGT, CGI, CWS, and ES Windows, among more than a dozen authorized lines. Most single-window replacements on Stock Island run $1,200 to $3,400 installed, depending on opening size, frame material, and whether the existing buck or jamb needs rebuilding. Older CBS homes almost always need new treated bucks because the original aluminum is too corroded to anchor into.

Impact Entry & French Doors
Waterfront and canal-side homes on Stock Island take a beating at the door threshold long before the glass ever fails. Salt spray works its way into hinges, thresholds, and locking hardware, and within five to eight years a door that was installed to mainland spec starts binding or leaking. We install impact-rated entry doors and French doors with marine-grade hardware as standard on Stock Island, not as an upcharge. Entry door replacements typically run $2,800 to $6,500, and French door sets run $4,500 to $9,000 depending on panel width, glass package, and frame condition.

Impact Sliding Glass Doors
Sliders are the most common large opening on Stock Island homes facing the water, and they’re also the first place wind-driven rain finds its way in during a storm. We install impact sliding glass doors with reinforced interlocking stiles, stainless steel rollers, and weep systems designed for salt exposure. A standard two-panel impact slider in Stock Island runs $3,800 to $7,200 installed. Larger multi-panel or telescoping configurations run higher, and we’ll quote those line by line so you see exactly what you’re paying for.

Impact Garage Doors
Garage doors are the largest single opening on any home, and on Stock Island they’re subject to both wind load and constant salt corrosion of tracks, springs, and hardware. We install impact-rated garage doors with galvanized or stainless hardware spec’d for the coastal environment. Expect to pay $2,500 to $5,800 for a single-car impact garage door and $4,000 to $9,500 for a double-car, installed. We also handle wind mitigation documentation tied to garage door ratings, which matters for your insurance credits.

Trusted Brands We Service in Stock Island
We’re an authorized installer for more than a dozen manufacturer lines, and for Stock Island homeowners we lean heavily on PGT, CGI, CWS, and ECO Window Systems. These brands have product lines engineered specifically for the Florida coastal market, with marine-grade hardware options and laminated glass that holds up to salt spray better than generic imports. Because we stock local parts and have established relationships with these manufacturers, we can turn around warranty service and replacement components faster than a company that has to ship everything from the mainland. We quote side by side on paper so you can compare glass packages, LOP ratings, and energy performance before you commit.
Common Impact Windows & Doors Problems We See in Stock Island Homes
- Salt corrosion on aluminum frames and hardware. Stock Island is surrounded by open saltwater on three sides, and that salt gets into every track, hinge, and seal. Standard aluminum components that last 15 to 20 years in Miami routinely fail here in 5 to 8, which is why we spec marine-grade materials from the start.
- Original jalousie windows that are now code non-compliant. The louvered glass windows that were standard on Keys-era homes are explicitly prohibited under current Monroe County wind code. Any remodel, inspection, or sale triggers forced replacement. Contractors who don’t know this lose jobs, and homeowners who ignore it face insurance complications.
- Failed insulated glass units from constant thermal cycling. Fog between the panes means the argon fill has escaped and the window has lost its insulating value. On Stock Island, the daily temperature swings and humidity accelerate this failure. The fix is full unit replacement, not a band-aid.
- Rotted or undersized window bucks in older CBS walls. When we open up a mid-century concrete block home, we regularly find the original wood or aluminum bucks so deteriorated that a straightforward window swap becomes a framing repair. We handle that in the same visit and price it upfront.

FAQs - Impact Windows & Doors in Stock Island
No. Jalousie windows are explicitly non-compliant with Monroe County’s current wind and impact code, which means they can’t be installed in new work and original units must be replaced when a remodel, sale inspection, or insurance review triggers code enforcement. If you have jalousies on your Stock Island home, the replacement is not optional. Call (954) 280-4413 and we’ll document the violation and quote a compliant impact replacement in the same visit.
Stock Island has saltwater on three sides with almost no land buffer, so the corrosion rate on standard aluminum frames, hinges, and sealants is materially higher than Miami’s. Hardware that lasts 15 to 20 years in Miami can fail within 5 to 8 years on Stock Island. Marine-grade stainless or heavily coated hardware is the baseline here, not an option. We include it in every Stock Island quote as standard.
The window replacement itself typically doesn’t trigger a full structural inspection, but if you’re pulling a permit for a remodel, the wind mitigation documentation comes with it. That’s actually good for you: documented impact-rated openings and a proper wind mitigation report can lower your insurance premium. We handle the paperwork and make sure the permit drawings reflect the credits you’re entitled to. Call (954) 280-4413 to talk through your specific project.
Yes, but the installation method is different. Mobile homes typically use a retrofit flange or direct-mount system rather than a standard frame-set installation, and we have to account for wall flex and the original aluminum framing. Stock Island has a significant inventory of manufactured homes, many from before the current wind codes, and we’ve done enough of them to know the right approach. Call for a free estimate and we’ll look at your specific home.
We inspect the opening first and tell you exactly what we found. If the original buck or jamb is too deteriorated to anchor into, we replace it with treated material, flash the opening with marine-grade tape, and price that work in the same written estimate. Nothing gets added to your bill that wasn’t approved in writing first. That’s the standard on every Stock Island job.
On a 1970s concrete-block home near Maloney Avenue, our crew removed original jalousie units and found the aluminum jambs so corroded from salt spray that the fusion-welded frames couldn’t be re-anchored at all. We had to install new treated bucks, flash the openings with marine-grade tape, and install ViewLux impact-rated double-hungs with low-E glass and argon fill. The permit drawings were updated same-day to reflect the code-required wind mitigation credits. Two mainland contractors had walked away from that job. We closed it, and the homeowner’s insurance premium dropped the following year.
If you’re planning work on Stock Island and want to know the true cost before the first window comes out, call TruePane at (954) 280-4413. We’ll come out, measure twice, and put the numbers on paper. Free estimate, fixed pricing, and both warranty layers registered before we leave your driveway.
