Windows and doors on Sanibel carry a burden mainland homes never face: 360 degrees of salt air, Gulf storm bands that arrive without warning, and a causeway that turns every material delivery into a logistics calculation. When you call TruePane Windows & Doors at (239) 323-5522, a live person answers, and you’re speaking with someone who knows the difference between a stilt home in Blind Pass and a garden-level condo near East End. We dispatch crews from our South Florida office to Sanibel weekly, and our technicians measure every opening twice before a single unit is ordered. You get straight answers, written quotes side by side, and no surprise line items. If you’re replacing windows or doors after Ian, or finally addressing the jalousie windows that have rattled through twenty hurricane seasons, this page covers what Sanibel homeowners actually need to know.

Why Sanibel Homeowners Choose TruePane Windows & Doors
Sanibel is not a place where you gamble on an unproven installer. The island’s housing stock has been through a catastrophic storm, years of permitting backlogs, and a rebuilding cycle that exposed every shortcut in the book. Homeowners in Shell Harbor and Gumbo Limbo call us because TruePane is led by Dale Kessler, a second-generation glazier who founded the company in 2008 on a rule that still hangs on the whiteboard: if the pane is not true, the job is not done. We’re an authorized installer for more than a dozen manufacturer lines, including Andersen, Pella, Marvin, PGT, and CGI. That matters on Sanibel because not every brand builds a unit that holds its structural rating after five years of salt spray, and not every installer registers both warranty layers in writing before leaving the driveway. We do that as a matter of standard practice under our Keystone Standard, and every job carries the 90-Day Done Right Promise. No paperwork fights, no arguing, no fine print that covers neither. Our background-checked, uniformed technicians work the way they would in their own mother’s house, because most of them live within an hour of the causeway and plan to be here in thirty years.
We answer the phone 24 hours a day, seven days a week. Not a voicemail tree, not a callback form. A person. When a Sanibel homeowner calls about a binding slider or a fogged seal, they talk to someone who can schedule the visit, explain the permitting path, and tell them honestly whether it’s a $89 seasonal tune-up or a replacement job. Our home base of operations is in South Florida, but the crews we send to Sanibel work on the island weekly and understand its rhythms: off-season lulls, pre-season rushes, and the narrow window between permitting approval and hurricane season when every homeowner wants the job done yesterday.
Windows & Doors Services We Offer in Sanibel
Impact Windows in Sanibel
Impact windows are the flagship line for Sanibel, and for good reason: they’re laminated glass units that meet Florida Building Code extreme-wind specs and Miami-Dade NOA where Sanibel’s wind zone demands it. Our design pressures are matched to each specific opening, and we never quote a rating above +/-100 PSF because no Sanibel opening requires more than that and selling overkill is a disservice. These are not plywood-and-pray units; they’re permanent protection that does the work of shutters without anyone hauling panels up a stilt ladder at 11 p.m. Learn more about our Impact Windows in Sanibel.
Window Installation in Sanibel
Post-Ian Sanibel is a different job site than mainland Florida. We’re routinely installing into fresh rough openings on newly permitted elevated stilt framing, not retrofitting 1970s wood frames. That means square openings, new flashing planes, and a chance to do the install correctly from the first screw. Learn more about our Window Installation in Sanibel.
Window Replacement in Sanibel
If your home survived the storm but the windows did not, or you’re still living with single-pane sliders from the 1980s, replacement is the answer and we handle it end to end. We remove the old unit, inspect the rough opening for rot or salt damage, flash the perimeter correctly, and set the new unit true. Learn more about our Window Replacement in Sanibel.
Door Installation in Sanibel
Entry doors on a barrier island fail at the threshold first: wind-driven rain, salt air, and constant humidity. We install doors with marine-grade hardware and thresholds that shed water away from the sill, not under it. Every door gets the same double-measured, double-registered treatment as our windows. Learn more about our Door Installation in Sanibel.
Sliding Glass & Patio Doors in Sanibel
Sliders are the weak point of nearly every older Sanibel cottage, and after Ian, most homeowners never want to see another jalousie or a flimsy aluminum slider again. We install impact-rated sliding and patio doors in PGT, CGI, Mr-Glass, and Therma-Tru lines, with stainless-steel rollers and tracks that don’t seize up in salt air. Learn more about our Sliding Glass & Patio Doors in Sanibel.
Energy-Efficient Windows in Sanibel
TruePane’s low-E, double-pane, impact-rated units cut cooling costs by 20 to 30 percent on the island, where air conditioning runs nine months a year. That is a real number, not an inflated one, and it’s why so many Sanibel homeowners pair impact protection with efficiency in the same unit. Learn more about our Energy-Efficient Windows in Sanibel.
Impact Garage Doors in Sanibel
The garage door is the largest single opening on most Sanibel homes, and the first thing to blow in during hurricane-force wind. We install impact-rated garage doors that meet the same Florida Building Code extreme-wind specs as our windows, with bracing systems designed for wind loads not just windborne debris. Learn more about our Impact Garage Doors in Sanibel.
Custom & Geometric Windows in Sanibel
Rebuilt Sanibel homes are getting more architectural interest: round-tops, trapezoids, transoms, picture windows sized for specific Gulf views. We fabricate custom units to match existing openings or brand-new plans, and we order with the same lead time as standard units; custom fabrication typically runs four to six weeks. Learn more about our Custom & Geometric Windows in Sanibel.
Roof Repair, Roof Replacement & Installation in Sanibel
Windows and doors are only as good as the roof they sit under, and post-Ian Sanibel has taught every homeowner that lesson. We offer roof repair and full replacement in shingle, tile, and metal systems, with the same straight-pricing, written-quote standard as our window work. Learn more about our Roof Repair, Roof Replacement & Installation in Sanibel.
What Sanibel’s Salt Air Does to Windows and Doors
Sanibel is not like Fort Myers Beach or Cape Coral, where buildings sit at the edge of one body of salt water. This island catches salt from three sides at once: the Gulf of Mexico on the west, Pine Island Sound on the east, and the broad sweep of San Carlos Bay to the north. The result is among the most corrosive atmospheric environments in Florida. Untreated aluminum frames oxidize and pit within a few years. Hardware that works fine in Cape Coral seizes up here. Wind-driven rain finds every unflashed seam and works it until the threshold rots or the flange leaks. That’s why we specify marine-grade anodized or powder-coated aluminum frames for every Sanibel job, and why solid stainless-steel or brass hardware is not an upsell, it’s the baseline. Standard “coastal Florida” hardware simply doesn’t hold up here, and any installer who tells you otherwise has not spent enough time on Sanibel.
For safety: any work involving the high-tension springs and cables on garage doors, or the removal of large, heavy impact-glass units, is dangerous. Those are not DIY tasks. We handle every install with trained, uniformed technicians, and if you have a door spring that’s snapped or a panel that’s cracked, call us at (239) 323-5522 rather than trying to release that tension yourself.
Neighborhoods We Serve in Sanibel
TruePane crews work all over the island, from the East End up through the interior neighborhoods and down to the Gulf-side streets where Ian did its worst. We know the difference between a 1950s beach cottage and a brand-new elevated build on the same street.
- Shell Harbor - canal-front homes with heavy water exposure and aging original windows.
- Gumbo Limbo - mid-island neighborhood where post-Ian rebuilds are most active.
- Blind Pass - the west end, closest to the pass, with maximum salt and wind exposure.
- East End - older cottages and condos, many still carrying jalousies and single-pane sliders.
- Periwinkle Way corridor - homes along the island’s main road, where deliveries and staging require extra care.
Typical response for Sanibel is same-week for estimates and as fast as a single day for installation once your custom units arrive on the island.
Pricing for Windows and Doors in Sanibel
Straight numbers, because that’s what homeowners actually want. Impact-rated window units in Sanibel, installed, run from roughly $1,600 to $2,800 per opening depending on size, frame grade, and glass package. A standard entry door starts around $2,200 and goes up from there for impact-rated slabs with marine hardware. Sliding glass and patio doors land between $3,500 and $6,500 installed, with wider multi-panel units running higher. Impact garage doors typically run $4,000 to $8,000, depending on the bracing system. These are all-in figures: labor, materials, flashing, caulking, and haul-off of the old unit, with both warranty layers registered in writing before we leave the driveway. The Sanibel Causeway complicates deliveries: oversized impact-glass units and patio door slabs need wide-load flat-bed scheduling, and that adds a line item no Fort Myers quote will show. We’re upfront about it because a square deal means nothing if the bill surprises you at the end. Call (239) 323-5522 for your free estimate.
Florida Pays Sanibel Homeowners Back
The incentives stack, and we make sure every Sanibel homeowner knows what’s on the table before they sign. The My Safe Florida Home program offers matching grants up to $10,000 for qualifying wind-mitigation upgrades, which includes impact-rated windows and doors. Florida also exempts impact-resistant windows and doors from sales tax, which saves real money on a five-figure job. On the federal side, the 25C energy credit covers 30 percent of product cost on qualifying energy-efficient units, up to $600 a year. Finally, after a wind-mitigation inspection (typically $75 to $150), many Sanibel homeowners see windstorm premium credits averaging around 25 percent on the windstorm portion of their policy. Those programs and carrier decisions are not ours to guarantee; the final numbers come from the state, the IRS, and your insurer. But we’ll point you to the right forms and make sure the units you order qualify. Call (239) 323-5522 and we’ll walk you through it.

FAQs About Windows and Doors in Sanibel
You should expect between $1,600 and $2,800 per opening for installed impact windows in Sanibel, depending on the frame grade, glass package, and whether the crew is working on a fresh rough opening or a retrofit of existing 1980s frames. The causeway delivery logistics may add a coordination fee. Call (239) 323-5522 for an exact quote; estimates are free.
Yes. Sanibel’s post-Ian rebuilding environment means the city enforces Florida Building Code wind-load requirements on virtually every window and door replacement, and permits are pulled for every job we do. We handle that process, including inspections, so the homeowner never has to chase paperwork.
Yes, and that is a large share of our current work on the island. Stilt construction means we’re installing into fresh rough openings in brand-new elevated framing, which gives us a clean, square substrate to flash and seal properly. We match design pressures to the specific opening and the home’s wind zone.
No. TruePane operates on fixed pricing with no change orders unless the homeowner requests a change in scope. If we discover rot or salt damage behind the old unit that adds work, we stop, show you the issue, and get your written approval before proceeding. No surprise line items on the bill.
Yes, we’ll point you to the program application and make sure the units you order meet the wind-mitigation requirements. The grant is not ours to guarantee; the state sets the terms and the final approval. Call (239) 323-5522 and we’ll help you get started.

What Sanibel Customers Say
"Whole-house window replacement at 71 years old is not something you want to do twice. Dale walked the house himself for the quote. Crew was the same three men all four days, and the foreman knew every window by room."
- Pat and Ray L."Our bay window had rotted at the sill and two other outfits wanted to talk us into a flat picture window instead. TruePane rebuilt the opening and matched the original look. Neighbors have knocked on the door about it."
- Gene A."Impact windows on the whole house. They handled the permit, the inspection, and gave me a folder with every approval number for the insurance company. My windstorm premium dropped enough to notice."
- Bill T.
