Call (239) 326-9942 for a free in-home measure and a written line-item quote before you commit to anything.
Marco Island is not like working the mainland. Every house sits on a barrier island with salt water on all sides, and we approach every opening that way. If you live off Bald Eagle Drive or Collier Boulevard or along the canals near Caxambas Pass, you already know the salt spray, the humidity, and the wind. We do too. Our crews work Marco Island neighborhoods every week, so we know what happens to window hardware out here after a few years of four-sided exposure.
Why TruePane Windows & Doors Is Marco Island’s Preferred Window Replacement Company
TruePane Windows & Doors was founded by second-generation glazier Dale Kessler on a simple rule: if the pane is not true, the job is not done. That standard governs every measure, every quote, and every install we do on Marco Island. We do not arrive with a price sheet and a clipboard and start pushing product. We measure every opening twice, quote manufacturer lines side by side on paper, and register both warranty layers in writing before our truck leaves your driveway.
Our Window Replacement team includes background-checked, uniformed technicians who treat your home the way they would work in their own mother’s house. That matters on Marco Island, where many of the homes were built by the Deltona Corporation starting in 1962 and still carry original jalousie or single-pane aluminum sliders. We have pulled enough of those out to know exactly what we are going to find behind the drywall, and we quote accordingly: no surprise line items, no second appointment left hanging.
Dispatch and scheduling for Marco Island are coordinated from our South Florida office, with crews serving the island locally. When you call, a live person answers 24 hours a day, 7 days a week. Not a voicemail tree. Not a call center in another state. A person who can tell you when we will be there and what to expect.
We stand behind the work with the 90-Day Done Right Promise. If it is not done right, we make it right. No paperwork fights, no arguing about who is at fault. That is the Keystone Standard, and it applies to every window we install in Marco Island.
Our Window Replacement Services in Marco Island
Most homeowners on Marco Island call us for one of four reasons. Here is what each one looks like on the island, not in a brochure.
Full Frame Replacement
Full frame replacement on Marco Island means pulling the entire window, frame and all, down to the rough opening. That is often the right call on the older Deltona Corporation CBS ranch homes where the original aluminum frames are pitted from salt air and the rough openings were never flashed to handle wind-driven rain from the canal side. We replace everything with new construction or retrofit impact-rated frames, proper sill pans, and marine-grade flashing on all four sides. On a CBS home near a canal, this is the only way to correct the corrosion and water intrusion that insert windows cannot fix.
Expect to pay more for full frame work than for inserts. The labor is heavier, the materials are heavier, and the detailing around the opening takes real time. A typical full frame impact window in Marco Island runs $1,200 to $1,800 per opening installed, more for large or custom openings.

Insert Window Replacement
Insert replacement windows fit inside the existing frame. They make sense when the frame is still square, still structurally sound, and not rotted or corroded. On many Marco Island homes, we find the frame is salvageable on two sides and shot on the other two. If the jamb hardware is pitted and the sill pan is pulling away, inserts will not fix the underlying problem. We tell you honestly which openings can take an insert and which need full frame work. Inserts in Marco Island typically run $800 to $1,200 per opening with impact glazing.

Vinyl Replacement Windows
Vinyl has become the practical choice on Marco Island for a reason. It does not corrode. Salt air eats aluminum; it does not eat vinyl. A well-built vinyl impact window with a multi-chamber frame and a good flange seal will outlast the original aluminum it replaces, and it costs less than comparable wood or fiberglass. We install vinyl replacement windows from manufacturers whose Florida Product Approval numbers match the wind zone on your street. Expect $800 to $1,500 per unit depending on size and design pressure rating.

Energy-Efficient Upgrade
Every window we install in Marco Island carries low-E glass and a warm-edge spacer as standard. That is not an upsell; it is what the climate demands. Air conditioning runs most of the year here, and the sun loads the west and south exposures hard from midday through late afternoon. Upgrading from single-pane aluminum to insulated impact glass cuts the direct solar gain and the air leakage through the frame. Homeowners notice the difference in their electric bill within the first full summer, especially on the Gulf-facing elevations.

Trusted Brands We Service in Marco Island
We are an authorized installer for more than a dozen manufacturer lines, including Andersen, Pella, Marvin, Milgard, Jeld-Wen, PGT, CGI, and ES Windows. On Marco Island, we quote PGT and Mr-Glass lines most often because their impact configurations carry the Florida Product Approval numbers Collier County’s building department expects on every permitted opening. We also work on Therma-Tru door systems where the front entry needs to match the window package. When you sit down with us for a quote, you see the manufacturer lines side by side on paper, with the warranty durations stated in writing. No guessing.
We keep common hardware and sealant stock on our trucks for Marco Island service calls, so a fogged seal or a corroded lock on a louver jamb does not mean waiting two weeks for parts.
Common Window Replacement Problems We See in Marco Island Homes
- Salt corrosion on all four sides. The canal system wraps behind most homes while Gulf breezes hit the street side, so there is no sheltered rear exposure. Jamb hardware, sill pans, and frame corners fail uniformly, and crews that assume one side is protected get callbacks.
- Non-impact single-pane sliders from the 1960s and 1970s. These fail wind-load design pressure under Miami-Dade NOA criteria by a wide margin. They are not just drafty; they are a blow-out risk in a near-direct hurricane strike like Irma in 2017.
- Improperly flashed sill pans on canal-facing rear walls. Wind-driven rain gets trapped behind inserts, rots the wood buck, and causes hidden mold that nobody sees until the window comes out. We find this on homes that had inserts installed years ago without the pan detail corrected.
- Fogged seals from salt-laden humidity. The humidity here attacks glazing seals faster than it does on the mainland. A double-pane unit that would hold argon for 25 years in Minneapolis fails in 12 to 15 on Marco Island unless it is built and sealed for a coastal environment.
What Window Replacement Costs in Marco Island
Here are the numbers, straight up. Impact windows in Marco Island generally run $800 to $1,500 per window installed. Impact single-hung units run $900 to $1,800 depending on size and design pressure. Large or custom openings, like a picture window facing the water or a sliding door system on a two-story great room, run $2,500 to $5,000 or more. Whole-home packages typically land between $8,000 and $25,000 plus, depending on how many openings and what wind zone the house sits in.
What moves the price on Marco Island specifically: the number of openings, the design pressure rating required by your wind zone, floor height (second-story work costs more to stage and flash correctly), frame material, and whether the job is full frame or insert. A canal-front home with 14 openings and full-frame impact replacement will run the high end of the range. A three-bedroom CBS on an interior street with inserts will run the low end. We measure every opening twice, quote it in writing, and we do not change the number once the contract is signed.

Florida Pays You Back
There are real incentives for impact window replacement in Florida right now, and a lot of Marco Island homeowners miss them. 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. The state also exempts impact-resistant windows and doors from sales tax on the product side of the invoice. On the federal side, the 25C energy credit returns 30% of product cost on qualifying energy-efficient units, up to $600 per year. And most Florida property insurers offer a windstorm premium credit after a wind-mitigation inspection, often averaging around 25% on the windstorm portion of the premium. The inspection itself typically runs $75 to $150.
Those numbers are set by the programs and the carriers, not by us. We cannot guarantee a specific credit on your policy. What we can do is install windows that carry the Florida Product Approval documentation and Miami-Dade NOA numbers your insurer wants to see, and we will point you to the inspection step when the work is done.
One comparison worth making: impact windows versus hurricane shutters. Shutters cost less up front, but they only protect the house when someone is home to hang them, and most people do not want to fight panels before a storm. Impact windows protect all year, they quiet the street noise, and they count toward your wind-mitigation credit permanently. We do not install shutters. We install the glass that means you never have to think about them.
Building on Marco Island: Permitting, Setbacks, and What It Changes
Marco Island is not an unincorporated patch of Collier County where you can pull a simple permit and go. It has its own building department, its own code requirements, and its own enforcement. When we replace windows on the island, the permit is pulled through the City of Marco Island, and the inspection is a city inspection. That matters because the city’s coastal wind-speed requirement means every permitted opening must be either impact-rated or protected by shutters. There is no “grandfathered single-pane” pass on a replacement.
Most Marco Island homes are not on acreage the way rural Collier County properties are. But the island’s development pattern does create two conditions that change the job: canal setbacks and dense street grids. On a canal lot, the rear wall sits close to the water, which means our crew stages from the street side and works the canal elevation with more labor and more care. The openings on that side also face wind-driven rain differently than the street side, so we flash them for wind loading on both faces, not just one. On interior streets, the homes sit close enough together that scaffolding and ladder access can be tight. We scope all of that before we quote, so the number you get includes the real access conditions, not a mainland assumption.
If you have outbuildings, a detached garage, or a guest cottage, those openings count too. A detached structure still needs impact-rated or shuttered openings if it is conditioned space, and the permit covers the whole property, not just the main house. We quote every opening on the lot at the same time so you are not back for a second permit in a year.
The Canal Effect: Why Four-Sided Corrosion Changes Everything
There is a reason we talk about four-sided corrosion on Marco Island and nowhere else. On the mainland, a house has a windward side and a leeward side. The back of the house is sheltered. Window hardware on the back wall lasts years longer than hardware on the front. On Marco Island, that is not the case. The canal system wraps behind most homes while Gulf breezes hit the street-facing elevation, and the tidal estuaries push salt-laden humidity from every other direction. The result is corrosion on all four sides of the structure at the same time.
On a Deltona Corporation CBS ranch near Bald Eagle Drive, our crew pulled out the original 1962 jalousie and single-pane aluminum sliders and replaced them with impact-rated PGT casement and double-hung units carrying Florida Product Approval. What they found was salt-driven pitting on every jamb, including the supposedly protected courtyard side. The homeowners assumed the front of the house took the worst of it. So did the previous contractor, who had only replaced the street-facing windows years earlier. The courtyard-side frames were just as far gone, and two of them were the ones leaking water into the wall cavity.
That is what the information-gain hook on this page means: window replacement on a barrier island requires four-sided corrosion detailing and county-level permitting tied to canal setbacks, not the one-sided windward logic that works on the mainland. If your contractor has not worked enough Marco Island homes to know that, they will not know to check the supposedly protected side until it is too late.

FAQs - Window Replacement in Marco Island
Because the City of Marco Island’s building code does not exempt interior streets from coastal wind-speed requirements, and because Hurricane Irma in 2017 proved that a direct or near-direct strike reaches every block on the island. Every permitted replacement opening must be impact-rated or protected by shutters, regardless of street location. Call (239) 326-9942 for a free quote on your specific openings.
It depends on the condition of the existing frame, but on many 1960s Deltona CBS homes we find the frames too pitted and the rough openings too poorly flashed for inserts to work correctly. We measure each opening and tell you honestly which can take an insert and which need full frame work. Call (239) 326-9942 and we will check yours in person.
It means the front of your house is not protected from salt the way it would be on a mainland lot. The canal wraps behind while Gulf breezes hit the street side, so both faces get salt-laden air year-round. We detail every opening, front and back, for corrosion resistance and wind-driven rain, not just the water-facing side. Call (239) 326-9942 for a quote that accounts for all four exposures.
Yes. Upgrading from single-pane aluminum to insulated impact glass cuts solar heat gain and air leakage in every room, and on Marco Island where air conditioning runs most months, the difference shows up on the bill within the first summer. The federal 25C credit also returns 30% of product cost on qualifying units, up to $600 per year. Call (239) 326-9942 and we will walk you through which units qualify.
Insurers look for impact-rated glazing with Miami-Dade NOA or Florida Product Approval documentation, proper wind-load design pressure ratings matched to the opening, and a wind-mitigation inspection report. All three are standard on every window we install in Marco Island. We register the warranty layers in writing before the truck leaves your driveway, and we point you to the inspection step when the work is done. Call (239) 326-9942 for the details.
