AfterCGI Windows & Doors in Marco Island, FL | Winslow Windows & Doors
We service and replace CGI windows and doors across Marco Island, and we do it as an independent company, not a factory arm. The short version: if your CGI slider is binding from canal salt, your Targa casement handle snaps, or your Estate single-hung won’t stay up, we fix it with OEM parts where they exist and straight replacement where they don’t. Ed Winslow’s crew has been pulling corroded CGI frames out of Deltona-era concrete-block homes on this island for years, and we know exactly what fails first here. Call (239) 899-6411 and a live person picks up.
Why Marco Island Residents Choose Us for CGI Service
We run one of the largest independent CGI window and door retrofit fleets on Marco Island. That matters because the work here is different from Naples, Bonita Springs, or anywhere inland. Our backlog spans original Mackle-era aluminum sliders, mid-2000s CGI Estate collection units, and current impact-rated CGI Targa by CGI lines, which means our techs know which jamb weatherstripping and roller cartridges fail first in salt-canal exposure, without any factory authorization. Ed grew up in Miami, learned the trade in Miami Dade College’s construction technology program, and has been working Southwest Florida long enough that his name on the truck still means he shows up to every job site at least once. Not to supervise. He wants to see how the light comes through a new window in a finished room. My name’s on the truck. That means I stand behind every frame we set.
We’re the independent shop that knows CGI equipment inside and out. No ticket numbers. No call centers. One phone number, answered by a person, any hour.
- Fully insured and licensed, with a published address and license number
- OEM CGI parts when available, so your original design wind rating stays intact
- Background-checked, uniformed techs on every truck
- The 36500-Day Done Right Promise: if it’s not done right, we make it right
- $40 off any repair over $200, a free second opinion on any written estimate, and no trip charge inside Collier County
Common CGI Windows & Doors Problems We Solve in Marco Island
- Salt-canal aluminum pitting on CGI Estate sliders. Marco Island’s tidal canal network pushes salt-laden air across bayside lots year-round. The raw aluminum edges of CGI Estate sliders start pitting within five to eight years, and the track binds so the door drags or locks up. We replace rollers, tracks, and weatherstripping, and we tell you straight when the frame is too far gone to save.
- CGI Targa casement handles that snap or spin free. Airborne salt accumulates in the multipoint lock gear track on Targa casements. After months of forced cranking during absentee season, the handle snaps or just spins without engaging. We clean and rebuild the gear track, replace the locking points with OEM parts, and get the window locking properly again.
- Leaking CGI Classic sliding patio doors after minor surge events. Original weatherstripping on CGI Classic sliders holds brackish flood residue after even a small surge near Barfield Drive. The result is persistent air leaks and higher humidity loads on adjacent drywall. We strip and replace the weatherstripping, realign the panel, and stop the leak at the source.
- Sash drop on older CGI single-hung windows. In concrete-block homes cooled mostly by pool-only air circulation, indoor humidity spikes. Spiral balance springs lose tension unevenly, and the upper sash drops or becomes hard to open. We replace balances and re-shim the sash for smooth operation.
- Corroded weatherstripping and hardware across the island. Between the open Gulf and the back-bay canals of the Ten Thousand Islands, Marco Island eats aluminum hardware faster than inland Collier County. We replace rollers, locking points, and weatherstripping before a draft becomes a water entry.
CGI Service in Marco Island: What Local Conditions Mean for Your Equipment
Here’s a fact you won’t find on a generic CGI page. Because the city of Marco Island was almost entirely built out by the Deltona Corporation between 1965 and 1980, nearly every original home on the east side shares the same slab-floor plan and jalousie pocket dimensions. When we replace CGI windows on a Barfield Drive canal lot, the adjacent three houses often need identical full-frame retrofits within the same insurance-renewal cycle. That shapes our bulk-ordering schedule, and it means we stock more of the specific frame sizes and CGI series parts for Marco Island than any shop that drives down from Fort Myers guessing what they’ll find. The island’s original jalousie windows are a specific insurance flashpoint. Most carriers now explicitly exclude wind damage coverage when jalousies are present, so replacement jobs here are often triggered by an insurer’s renewal ultimatum rather than a homeowner waking up and deciding they want new glass. That changes the timeline, the questions homeowners ask, and the way we sequence the work to get the insurance form signed off.
Our crew pulled a corroded CGI Estate series single-hung from a 1972 concrete-block canal home off Bald Eagle Drive after the owner received a Citizens policy cancellation notice. The aluminum frame had deep pitting along the lower track from salt spray, and the spiral balance had snapped, leaving the upper sash jammed against the brickmold. We did a full-frame replacement with a current CGI impact-rated single-hung as part of our Impact Windows in Marco Island service, set the new buck flush to the original Deltona opening, and finished the stucco return in one day before the reinspection deadline. That’s the kind of timeline Marco Island insurance renewals actually require.
CGI Models & Products We Service in Marco Island
We service and replace the full CGI lineup you’re likely to have on this island: the CGI Estate Collection single-hungs and sliders, CGI Targa by CGI impact-rated casements and picture windows, CGI Classic sliding glass doors, and the CGI Contractor Series windows you see in older condo associations. Our parts approach is simple. We replace any moving or sealing component, rollers, weatherstripping, locking points, balances, with OEM CGI parts when available to preserve the original design wind rating. If a frame is too corroded or the failing part is from a discontinued CGI series, we recommend a full replacement with a current impact-rated CGI or PGT unit rather than patching a non-compliant opening. Marco Island’s code and insurer mandates leave no room for compromised glass. We’re also an authorized installer for PGT, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux, so when a CGI replacement isn’t the right call, we’re not stuck with one option.

CGI Service Pricing in Marco Island
CGI repair pricing in Marco Island runs in bands, not mysteries. A roller replacement on a single slider panel typically lands between $145 and $240. Weatherstripping replacement for one door or window runs $85 to $180. A multipoint lock rebuild on a Targa casement is usually $210 to $330. Spiral balance replacement on a single-hung runs $160 to $240 per sash. Our Marco Island Window Installation for full-frame CGI impact window replacement starts around $1,100 to $1,700 per opening, including the new buck, stucco return, and interior trim, though canal-front homes with two or three exposed sides and limited access can push toward the top of that range. A full-home CGI retrofit on a Deltona-era canal lot typically lands between $18,000 and $42,000 depending on opening count, water exposure, and whether you’re going Estate or Targa. Every estimate is free, written, and line-itemed, fixed pricing with no change orders. Call (239) 899-6411 and we’ll walk the house with you.

FAQs - CGI Windows & Doors in Marco Island
If the water reached the bottom rail, the weatherstripping is done, no question. The sash itself only needs replacement if the glass seal has failed, the frame channel is pitting, or the sash no longer sits square in the track. Flood residue works into the wool pile and rubber bulb, and once it crystallizes with salt, air and water move through. We come out, pull the sash, inspect the channel, and tell you which one you actually need. Call (239) 899-6411 for a free inspection and a line-item estimate.
Almost never on a Mackle-era frame. The original aluminum frames were built for single-pane, non-impact glass, and they don’t have the structural depth or the glazing channel to carry a code-approved impact laminate. On most Marco Island homes, the frame itself has pitting at the track, so anything short of a full-frame replacement leaves you with the same weak point. We’ll tell you if you’re the rare exception, but expect a full-frame swap. Call (239) 899-6411 for a straight answer on your specific opening.
Salt is the culprit. Airborne salt from the Gulf and the tidal canals settles into the multipoint lock gear track on the Targa casement. Months of non-use let it cake and harden. When the owner returns for season and cranks the handle, the salt has already seized the gear track. The handle snaps or spins free. It’s not a defect in the window, it’s the environment. We rebuild the track and replace the locking points with OEM parts. Call (239) 899-6411 and we’ll get your casement locking again before the next storm watch.
Most Estate collection moving parts are still available: rollers, weatherstripping, locking points, and balances. What’s getting scarce is trim hardware and some frame extrusions from the earliest Estate runs. If we can get the OEM part, we use it to preserve your design wind rating. If the specific piece is discontinued, we tell you before touching the window, and we walk through the replacement math honestly. Call (239) 899-6411, and we’ll check your series number against current availability.
This is almost always a failed sill wedge or corner seal combined with wind-driven rain stacking against the face of the house. Marco Island’s east side catches the full brunt of afternoon storms with no dune line to break the wind. The seal at the bottom corners lets go first. We reset the glass, replace the corner seals, and re-flash the sill pan so the water sheds outward. Call (239) 899-6411 and we’ll identify the exact failure point.
