Fast, Reliable Windows & Doors Across Sanibel
Sanibel homeowners know that after Hurricane Ian, getting windows and doors right isn’t optional. It’s a structural and financial decision that directly affects your insurance premiums, your home’s survival in the next storm, and whether you pass the city’s own building inspection. Groundwork Construction Co. of Fort Myers brings impact-rated products, Sanibel-specific permit knowledge, and crews who understand the island’s High-Velocity Hurricane Zone code requirements to every job. We answer the phone live, 24/7. Call (844) 638-7249 to schedule your free project estimate and design consult.
Why Groundwork Construction Co. of Fort Myers Is Sanibel’s Preferred Windows & Doors Company
We built our reputation in Sanibel the hard way. Since Ian, we’ve been on-island weekly, replacing failed windows and doors in elevated piling homes on West Gulf Drive, mid-island ranch houses near the Bailey Tract, and waterfront properties along Sanibel-Captiva Road. Homeowners keep calling us back because we show up in uniform, we’re background-checked, and we quote the full scope upfront. No addendums when the rough opening reveals concealed rot. No change orders because someone forgot the stainless anchors.
Our Windows & Doors team knows the difference between a mainland Fort Myers permit package and the one Sanibel’s building department actually requires. Sanibel operates its own inspection calendar, separate from Lee County, and every impact-rated opening needs Florida Product Approval numbers on file before the inspector signs off on the rough-opening dry-in. We handle that paperwork start to finish. And our 730-Day Done Right Promise means if something isn’t right, we make it right. That’s one of the longest workmanship guarantees in residential construction, and it’s in writing on every Sanibel project.
Our crews service Sanibel directly, with all scheduling and dispatch coordinated from our South Florida office to route around the Causeway’s tourist-season backups. We time concrete pours, dumpster swaps, and material deliveries so your project doesn’t stall in bridge traffic. Calls are answered by a live person, day or night, so you’re never waiting until Monday to reach someone who can help.
Our Windows & Doors Services in Sanibel
Impact Windows & Doors
Sanibel’s High-Velocity Hurricane Zone provisions require all windows and doors within one mile of the Gulf to meet a design pressure rating of at least +/- 75 psf. That’s not a recommendation. It’s what the city inspector checks on every opening. We install PGT WinGuard, Andersen E-Series impact-rated, and other systems carrying DP 70 to DP 80 ratings, with the Florida Product Approval numbers documented in your permit file so your insurer can verify the wind-mitigation credit.
Hurricane Impact Windows
On Sanibel’s east end, where Ian’s surge was most destructive, we’re replacing original single-pane aluminum frames with impact casement and picture windows rated for full coastal exposure. Every window we install uses stainless steel or hot-dipped galvanized fasteners. Salt air eats standard hardware in two seasons. Non-impact windows that survive one storm often fail the next because corroded frames lose their seal, and a failed seal means a failed wind-mitigation inspection and a denied claim.
Impact Sliding Glass Doors
We replace seized, salt-corroded sliders on Sanibel’s mid-century beach cottages with impact-rated Andersen E-Series and PGT sliding doors carrying DP 80 ratings. The old aluminum tracks and rollers corrode so badly in the island’s salt environment that the door won’t budge. That’s an emergency egress failure on top of a structural one. The new units are engineered for Florida coastal conditions and documented for insurance compliance.
Window Replacement
A standard window replacement in Sanibel costs $4,500-$15,000, depending on the number of openings, the chosen brand, and the engineering needed to anchor the new buck framing into the existing wall. Many of the 1950s-70s homes we work on had floor-to-ceiling jalousie windows with minimal rough-opening framing. The opening has to be re-framed and flashed correctly. Skip that step and wind-driven rain gets behind the window, rotting the wall cavity before anyone notices.

Trusted Brands We Service in Sanibel
We partner with manufacturers whose products are tested and approved for Florida’s coastal building zones. Our Sanibel customers consistently choose Andersen, PGT, and Marvin for impact-rated windows and doors, paired with stainless hardware and hot-dipped galvanized fasteners that hold up in the island’s salt-laden air. We also work with ActiveYards and Belgard when projects extend to outdoor living spaces. Because we run so much volume through these brands, lead times stay predictable and warranties are direct from the manufacturer, backed by our own 730-Day Done Right Promise.
Common Windows & Doors Problems We See in Sanibel Homes
- Aluminum frame corrosion from salt spray. The constant salt mist off the Gulf eats standard aluminum frames and fasteners. Once the metal corrodes, the glass seal breaks and air and water infiltrate the wall. Sanibel inspectors flag this immediately on wind-mitigation re-checks, and an insurer won’t write a discount for a window that’s visibly losing its seal.
- Seized slider tracks on original patio doors. Older non-impact sliding glass doors on Sanibel’s concrete-slab homes develop salt-caked rollers and corroded tracks. The door becomes inoperable, which is both a life-safety egress violation and a code failure requiring full replacement with an impact-rated unit.
- Wind-driven rain penetration behind improperly flashed impact windows. On elevated piling homes, the rough opening is fully exposed to wind from below. If the flashing detail isn’t perfect, water gets driven into the wall cavity and rots the wood framing. We regularly find this on homes where the windows were replaced during the post-Ian rush and the flashing was cut short to speed the job.
- Insufficient design pressure ratings for the home’s actual location. A window rated for DP 50 might pass in inland Fort Myers but will fail in Sanibel’s near-coastal zones, where the minimum is DP 75. Homeowners who don’t check the Florida Product Approval number against the city’s wind-load map end up with windows that don’t meet code and can’t be insured at full value.

FAQs - Windows & Doors in Sanibel
Every impact-rated window or door installed in Sanibel must carry a Florida Product Approval (FPA) number issued by the Florida Department of Business and Professional Regulation. You can look up the approval at floridabuilding.org by entering the manufacturer’s name and product series. The FPA number is printed on a label affixed to the frame, and our permit package includes a copy of the approval with the design pressure rating clearly stated. Sanibel’s building department will not sign off on a final inspection without this documentation on file.
Yes. Sanibel’s building department requires a permit for any replacement of an exterior opening, even a single door, because the new unit must meet current HVHZ design pressure requirements and the installation must pass a rough-opening inspection before dry-in. We pull that permit, schedule the inspection with the city’s own inspector, and ensure the Florida Product Approval number and NOA (Notice of Acceptance) are recorded in the file. Skipping this step voids the manufacturer’s warranty and jeopardizes your wind-mitigation insurance credit. Call (844) 638-7249 and we’ll walk you through the process.
If the original manufacturer’s label with the DP rating and FPA number is missing or illegible, you’ll need a licensed contractor or engineer to determine whether the window meets the current code. On Sanibel, where the minimum coastal requirement is DP 75, unlabeled windows installed before Ian are almost certainly non-compliant. The glass may have survived one hurricane but offers no documented wind-load rating for the next one. That means your insurer can deny the wind-mitigation discount or even reduce coverage on the structure.
Impact windows do not directly lower a flood insurance premium through the NFIP, but they can reduce your windstorm insurance premium through a wind-mitigation credit when documented correctly. Your carrier, particularly Citizens or a private coastal writer, will require a completed wind-mitigation inspection report listing each opening’s FPA number and design pressure rating. We provide that documentation in a format carriers recognize, and on Sanibel we’ve seen the credit reduce the wind portion of a premium by hundreds of dollars annually. For an exact quote on your home, call (844) 638-7249 and we’ll explain what your specific policy requires.
Sanibel does not currently operate a standalone municipal rebate program for impact windows, but Lee County and the State of Florida have administered post-Ian resilience grants through programs like Rebuild Florida and the Hurricane Restoration Reimbursement Grant Program, which have included window-hardening as an eligible activity. Availability changes as funding cycles open and close. We track those programs for our Sanibel clients and can point you to the current application window when you call (844) 638-7249 for your free estimate.
