Fast, Reliable Windows & Doors Across Marco Island
If you own a home on Marco Island, your windows and doors are your first line of defense. We are talking about salt spray that eats hardware for breakfast and wind loads that inland towns never see. At Groundwork Construction Co. of Fort Myers, our Windows & Doors crews know every inch of this island. We understand the Mackle-era concrete shells, the newer elevated custom builds, and the very specific paperwork Collier County demands. A window here is not just a window. It is a structural safety system, a humidity barrier, and the single biggest lever you can pull to lower your windstorm insurance bill. Call us at (844) 638-7249 when you are ready for a quote that accounts for real Marco Island conditions, not a generic brochure price.
Why Groundwork Construction Co. of Fort Myers Is Marco Island’s Preferred Windows & Doors Company
We have been putting our reputation on the line in Southwest Florida for over 42 years, and Marco Island holds a special place in our daily work. Our crews cross the Jolley Bridge every morning with trucks stocked for the realities of 34140 and 34113. We do not show up surprised by a corroded 1974 buck or a canal-front lot that demands double the design pressure of a mainland subdivision. Our background-checked, uniformed technicians treat your home like the multi-million-dollar asset it is. That means shoe covers, clean drop cloths, and a meticulous silicone seal at every rough opening. We carry Liability and Workers’ Comp coverage, and our mechanical work is backed by the 730-Day Done Right Promise, which is one of the longest workmanship guarantees in residential construction. If it is not done right, we make it right, period.
We also answer the phone. Not a voicemail robot, not a call center a thousand miles away. A live person, 24/7. When a summer squall cracks a pane and you need a board-up assessment at 10 p.m., you will talk to someone who can help, right then. Derek Hollenbeck has built this operation on the principle that a contractor who can not be reached is just another liability. For Marco Island homeowners, that reliability can mean the difference between an insurance headache and a closed, secure home before the next band of rain rolls in from the Gulf.
Our Windows & Doors Services in Marco Island
Every opening in your home gets full scrutiny from our team. We do not just slap a new frame into an old hole. We evaluate the rough opening, the condition of the lintel, and the anchorage points because on an island with Exposure D wind loads, the connection to the wall is everything.
Hurricane Impact Windows
This is our bread and butter on Marco Island. You need an assembly, glass, frame, and anchorage, that carries a valid Miami-Dade or Florida Product Approval number and is rated for a High-Velocity Hurricane Zone. We install PG-50-rated systems from trusted manufacturers that meet the 80 psf design pressure common on waterfront lots here. When we pull a permit for impact windows near Snook Inn or anywhere along the canals, we are engineering each opening to the specific wind-load calculations for that elevation, not just guessing with a generic product. The result is a cleaner inspection, a faster sign-off, and a wind mitigation credit that can slice 30-40% off your Citizens or private-market premium.

Impact Sliding Glass Doors
A massive multi-slide door facing the Gulf is a beautiful thing until salt creep seizes the track. We replace corroded aluminum sliders with heavy-duty impact-rated systems that use Type 316 stainless steel rollers and hardware. The old Mackle-era doors often sit right on the slab without a proper capillary break. On Marco Island, that lets salt-laden moisture wick straight up into the sill, rotting the sub-sill blocking even on relatively new builds. We correct that with stainless steel pan flashing, a positive-slope sill, and a bonded seal that keeps the framing dry for the long haul.

Window Replacement
Whether you are pulling the original jalousie windows out of a 1970s CBS cottage or upgrading single-pane sliders that fog up every morning, we handle it. On Marco Island, the standard window replacement runs $4,500-$15,000 depending on the count and the product rating. Our team sizes each unit precisely because the concrete bucks in these older homes were not always square. We scribe, shim, and epoxy-anchor every frame so the finished opening is true and the weather seal is continuous. That matters when a September hurricane pushes six inches of horizontal rain against your west-facing wall.

Impact Windows & Doors
Most Marco Island projects pair windows and doors together to get the full insurance discount on one wind mitigation inspection. We handle the whole package: casements, horizontal rollers, single-hung impact units, and custom front entry doors with laminated glass and multi-point locking hardware. By sourcing all the openings from the same approved product line, we keep the engineering consistent and the permit paperwork straightforward. That saves you time at the Collier County Building Plan Review desk.

Trusted Brands We Service in Marco Island
We are not beholden to a single manufacturer, but we refuse to install a product we can not stand behind for decades. On Marco Island we install heavily from PGT, Andersen, and Marvin because their HVHZ-approved product lines have the design pressure ratings and the corrosion-resistant hardware packages this island demands. We also stock a full complement of 316 stainless fasteners, adhesives, and flashing materials in our service vehicles so a simple hardware call does not turn into a two-day delay. When we tell you the window assembly is rated for 170+ mph wind-borne debris, the paperwork will prove it. That is the documentation your insurance carrier needs to issue the discount.
Common Windows & Doors Problems We See in Marco Island Homes
- Salt-corroded aluminum sliders that seize shut. We regularly pull Mackle-era sliding glass doors with tracks so pitted and painted-over they physically cannot open. Beyond the obvious frustration, a stuck slider is an egress code failure and a real danger during evacuation orders. We replace the entire assembly with stainless-steel roller systems on impact-rated frames.
- Galvanized anchors failing on impact windows. A budget install might use standard galvanized steel concrete anchors. In Marco Island’s salt air, those anchors pit within two or three years, compromising the design pressure rating of the whole window. We epoxy-set Type 316 stainless anchors exclusively, and we verify the embedment depth on every buck.
- Fogged, failed seals on double-pane units. The constant humidity cycle, hot days, steamy nights, air conditioning blasting inside, creates a brutal environment for insulated glass. Once the desiccant inside the spacer is saturated, the pane fogs permanently. We replace failed IGUs with units that carry the same Miami-Dade NOA as the frame so your product approval stays intact.
- Patio door sill rot on ground-level slabs. Lots on Marco Island sit low and flat. Without a raised curb or a capillary break, moisture wicks straight from the concrete into the door sill, delaminating the flashing and rotting the sub-sill. On our installs, we build up the rough sill with a rot-proof composite shim and a stainless pan flashed to the WRB so water drains out, not in.

FAQs - Windows & Doors in Marco Island
A canal-front or direct Gulf-front lot on Marco Island typically falls under Exposure D in the wind-load calculations, which means each window and door assembly must handle higher uplift and lateral pressure than an inland Exposure B or C location. In practical terms, most waterfront openings here require a design pressure rating of at least +80/-80 psf, and the product approval must clearly show it was tested for a High-Velocity Hurricane Zone with wind-borne debris. Our team runs the specific ASCE 7 calculation for your address and lot elevation before ordering a single unit. Call (844) 638-7249 if you need a wind-load analysis and a compliant quote.
When you replace windows under a Collier County permit with HVHZ-approved impact products, the installation is documented and the product approval numbers are recorded. After the final inspection, you hire a licensed wind mitigation inspector who verifies the opening protection and submits a Uniform Mitigation Verification Inspection form to your insurer. That form is the trigger. It tells the carrier that every glazed opening is protected by a rated impact system, which eliminates the “glazed opening protection” surcharge and, on Marco Island, frequently cuts the windstorm portion of a Citizens or private policy by 30-40%. Without the permit and the product paperwork, the discount does not exist. Call us for an install that produces the paper trail your agent needs.
You pull a building permit through Collier County’s ePlan system, submitting the Florida Product Approval documents for the specific window or door assemblies you intend to install. Because the existing home is concrete block, the plans must detail the anchorage method, typically epoxy-set stainless steel screws or expansion bolts into the existing concrete buck, and demonstrate compliance with the wind-load requirements of FBC Chapter 16. Our office handles the submittal for you. Once the permit is issued, we install, call for a rough inspection (if the buck is exposed), and then a final inspection after the openings are trimmed and sealed. We do not collect the final check until the job passes and the permit is closed.
In most cases you can reuse the concrete buck, but you have to address the embedded steel. The original bucks in Mackle-era homes often have steel reinforcing or old steel anchors that have been wicking salt moisture for 50 years. If that steel has rusted and expanded, it can crack the concrete from the inside and will not hold a new anchor reliably. We inspect the buck for spalling and delamination. If the concrete is sound, we drill out the old corroded fasteners and epoxy-set new 316 stainless anchors into fresh holes. If the buck is compromised, we form and pour a new buck before the window goes in. Skipping this step is how you get an impact window that is technically bolted in but fails structurally when it matters.
No. The FEMA “50% rule” applies to any structure in a Special Flood Hazard Area, whether that is an AE zone or a VE zone, and on Marco Island the vast majority of lots fall into one or the other. The rule states that if the cost of improvements (including window and door replacement) over a five-year period exceeds 50% of the structure’s market value, the entire building must be brought up to current flood code, which usually means elevating. A typical whole-house impact package at $25,000 might not trigger it alone, but if you are also remodeling a kitchen or adding a patio roof, the cumulative number matters. We help you think through that math before we pull the permit so there are no surprises from the floodplain manager.
