Fast, Reliable Windows & Doors Across Marco
On Marco Island, a window or door that doesn’t seal tightly isn’t just an annoyance, it’s a structural problem waiting to happen. Our crews know that the salt air and canal-side humidity here corrode fasteners, rot wood bucks, and warp cheap frames faster than nearly anywhere else in Collier County. If you need a window that opens smoothly or a sliding door that doesn’t whistle when the wind kicks up, call us at (844) 638-7249. We serve every neighborhood from Olde Marco to the Estates, and our Windows & Doors team understands what these homes demand. When a rusted lintel or a blown-out seal shows up mid-project, we handle it without turning a two-week job into a two-month headache.
Why Groundwork Construction Co. of Fort Myers Is Marco’s Preferred Windows & Doors Company
Derek Hollenbeck built this company on a simple standard: if it’s not done right, we make it right. Every Windows & Doors in Marco project carries our 730-Day Done Right Promise, one of the longest workmanship guarantees you’ll find on a residential window or door installation in Southwest Florida. That matters here because salt-driven corrosion doesn’t always show itself in the first six months. It shows up after a full wet season, when hidden rust finally lets go of a sill anchor or a lintel begins to sag. Our guarantee gives you two full hurricane seasons to know the openings are solid.
Our technicians are background-checked and arrive in uniform, which is especially important on Marco where tight lots, gated communities, and canal-front homes mean neighbors and HOA boards are watching closely. We coordinate staging, parking, and debris management so the project stays clean and the neighbors stay calm. Dispatch and scheduling for our crews in Marco are handled from our Miami office, which keeps everything moving even when a storm is spinning in the Gulf.
We answer the phone with a live person, 24/7. It’s a real commitment, not a recording, and it means the same team that sold the job is reachable when a question pops up about a permit hold, a material delay, or a 50%-rule trigger you didn’t see coming. When you work on a barrier island where the rules change block by block, that kind of access is worth more than a lower bid.
Our Windows & Doors Services in Marco
Hurricane Impact Windows
On Marco Island, impact windows are not a luxury upgrade. They are code-required protection against design wind speeds that push 150 to 160 mph, and they have to hold up under salt spray that eats standard hardware in a few wet seasons. Our impact window installations in Marco typically run $8,000 to $25,000, depending on the number of openings and whether we are replacing original jalousie units or larger fixed-glass panels. Every job includes a close inspection of the existing rough opening for rusted lintels, rotted wood bucks, and corroded sill anchors, because on a Deltona-era home near the water, at least one of those will need attention before we can set the new frame.

Window Replacement
Replacing windows on a 1960s or ’70s concrete-block ranch in Marco is rarely a one-for-one swap. Years of reflected canal glare warp hollow vinyl frames, and the original steel lintels rust through from salt-laden air blowing off the Gulf. A standard window replacement here ranges from $4,500 to $15,000, with the final number shaped by how many openings need structural reframing. We bring stainless-steel connectors and pressure-treated lumber onto the job by default because we know what is waiting behind that stucco. Our 730-Day Done Right Promise covers the work and the hardware so a failed seal or a binding sash doesn’t become your problem next August.

Impact Sliding Glass Doors
A sliding glass door on a canal-front home in Marco takes more abuse from wind, salt, and humidity than any other opening in the house. The original hollow-core sliders from the Deltona buildout are particularly vulnerable: the tracks corrode, the rollers seize, and the frames warp until the door won’t lock or seal. We replace them with impact-rated sliding glass doors that meet Collier County’s current wind-load standards, using corrosion-resistant track hardware that holds up to brackish air. Most whole-door replacements in Marco fall between $3,500 and $9,000, including removal of the old unit, reframing if the sub-sill is rotted, and re-flashing to keep wind-driven rain out of the wall cavity.

Door Installation
Exterior doors on Marco Island homes face the same salt-driven corrosion cycle as the windows. The steel hinges and threshold plates rust, the weatherstripping deteriorates in the UV and the damp, and a poorly sealed door becomes a water entry point during a heavy summer squall. We install fiberglass and steel entry doors with composite frames that resist rot and swelling, and we carry the same design-pressure ratings required for impact-rated windows because a front door that blows in during a storm pressurizes the entire house. Pricing depends on whether we are setting a single entry door or a paired door assembly with sidelights, but a typical replacement with impact-rated hardware and new flashing starts around $2,500 and runs upward from there based on the opening condition we find.

Trusted Brands We Service in Marco
We stock and install windows and doors from Andersen, Marvin, and Pella because those three manufacturers build products tested to the wind and water ratings Collier County demands on the barrier island. Our relationship with these suppliers means we can source custom-sized impact units without long lead times, which keeps a whole-house window swap on schedule even when the rough openings are not standard Deltona dimensions. It also means the hardware, glazing, and frame coatings are backed by the manufacturer’s own warranty on top of our 730-Day Done Right Promise, so you’re never stuck arguing with a supply house over a failed seal or a delaminating sash.
Common Windows & Doors Problems We See in Marco Homes
- Rusted steel lintels over windows and sliding doors. Original 1960s steel lintels corrode from decades of salt-driven exposure, causing header sag and binding operation long before the glass fails. Once the lintel loses its bond with the masonry, the opening has to be reframed before a new unit can be set.
- Warped and leaking hollow vinyl sliders. Many of the “upgrade” sliders installed in the 1980s and ’90s have permanent frame warp from Marco’s reflected canal glare. The tracks distort, the seals fail, and air and water start bleeding around the panels, driving up humidity inside the house.
- Corroded sill anchors and wood bucks behind hurricane shutters. When shutters or impact glazing were retrofitted onto original Deltona slabs, the fasteners often trapped moisture against the stucco buck. The wood rots, the anchors loosen, and the entire assembly can blow out during a near-miss storm instead of protecting the opening.
- Fogged and seal-failed insulated glass units. The constant thermal cycling from Marco’s intense sun and air-conditioned interiors stresses the edge seals on older double-pane units. Once the seal goes, moisture creeps in, the glass fogs permanently, and the unit loses its insulating value and much of its impact rating.

Project Realities on a Tight Marco Lot
On Marco Island, window and door replacements on Deltona-era homes often reveal embedded metal connectors and fasteners corroded by decades of salt air and brackish canal exposure, forcing unplanned upgrades to stainless steel or coated hardware to meet current code before the new openings can be closed. This is not a hypothetical risk. It is predictable, and it changes the way a responsible crew stages the job.
On a 1967 concrete-block ranch along Buttonwood Court, our crew removed the original jalousie windows and hollow-core sliding glass doors to find the steel lintels and sill anchors so rusted from canal-side humidity that the rough openings had to be reframed with pressure-treated lumber and stainless connectors before we could set the new impact-rated units, a condition we see on nearly every teardown-era home here that’s within a block of the water. Because we expect these conditions, we stage the job differently. We bring scaffolding and debris chutes that fit a narrow side yard. We protect the neighbor’s property line with temporary screening. We schedule material deliveries so they don’t stack on the street or block a shared driveway. And we keep the site clean at the end of every workday because on Marco, a messy site is a complaint to the HOA waiting to happen.
Site access directly shapes the quote. If our crew can’t get a dumpster within reasonable distance of the openings, removal takes longer. If the HOA restricts working hours, the schedule stretches. We price those realities honestly from the start so there are no mid-project surprises. That’s upfront pricing, no surprises, built around how Marco Island actually works.

FAQs - Windows & Doors in Marco
It can, especially if the home has not been elevated above the current FEMA Base Flood Elevation. Under Collier County’s substantial improvement rule, any renovation that exceeds 50% of the structure’s assessed value triggers full flood-compliance reconstruction. A whole-house window and door replacement alone usually falls below that threshold, but if you are combining it with other work, the cumulative cost can push you over. We help every Marco homeowner run the math before we write the quote so there are no surprises. Call (844) 638-7249 and we will walk you through it.
Fiberglass and properly coated aluminum frames hold up significantly better than hollow vinyl or bare wood in Marco’s salt-laden air. Vinyl frames warp under the reflected canal glare and the thermal cycling between sun and air conditioning. Wood bucks rot from trapped moisture behind stucco. We recommend fiberglass or marine-grade aluminum with stainless-steel hardware for any opening within sight of the water, and we default to stainless connectors on every job here regardless of the frame material.
Yes. Marco Island sits fully inside the High Velocity Hurricane Zone, with ultimate design wind speeds reaching 150 to 160 mph. Wind-borne debris requirements are stricter here than inland, especially on Gulf-front and canal-front parcels in VE flood zones. The impact windows we install are tested and labeled for the exposure category and design pressure rating specific to your parcel. We pull the permit and submit the product approvals to Collier County so the inspection passes on the first visit. Call (844) 638-7249 for a free estimate that includes the right rating for your home.
Sometimes, but widening a rough opening in a concrete-block wall on a Deltona-era home is structural work that requires an engineer’s letter and a permit. If the new header changes the load path, or if the existing lintel is already rusted and compromised, the scope grows quickly. On homes that sit below BFE, enlarging an opening can also trigger the 50% substantial improvement rule if the cost of the structural work pushes the total project value past the threshold. We will tell you honestly whether a larger opening makes engineering and financial sense before we pull the permit.
We plan the staging around the lot, not the other way around. On a narrow canal-front lot with limited side-yard access, we use compact scaffolding, debris chutes, and small-footprint dumpsters that fit a standard driveway. We protect landscaping with plywood and tarps, run temporary screening along property lines, and clear all debris at the end of each day. We also coordinate material deliveries in small batches so nothing sits on the street or blocks a neighbor’s access. The goal is to finish the job without a single complaint from the HOA or the house next door.
If your Marco Island windows rattle in the wind, your sliding door sticks, or you are just tired of the humidity creeping through old seals, call (844) 638-7249. Our team will give you a free estimate, a written quote, and the straight answer on what your openings actually need. Built to last, backed in writing.
