CGI Windows & Doors in Windermere, FL | TruePane Windows & Doors
We provide independent CGI windows and doors service across Windermere, from full-frame impact replacements on Butler Chain lakefront estates to hardware and seal repairs on older CGI models. For homeowners looking beyond our area, we also offer Windermere Window Installation expertise that informs our regional approach. The work here is different because Windermere’s lakefront microclimate and custom home stock push CGI products harder than almost anywhere else in Orange County. Dale Kessler and our crew have rebuilt, retrofitted, and reinstalled CGI windows and doors in Windermere since before CGI became a household name in Florida impact glazing. If you need CGI service in Windermere, call (754) 238-2201.
Why Windermere Residents Choose Us for CGI Service
CGI is not a manufacturer line we picked up last year to chase a market. Our techs know the Estate Series, Classic Series, 1500 Series sliding glass doors, and 9010 Series single-hungs the way a mechanic knows a particular engine family, because we have been inside enough of them to know where they fail and why. Windermere homes present a specific set of problems: oversized picture windows on lake-facing elevations, multi-panel pocket sliders that carry more wind load than the original spec anticipated, and hardware that corrodes faster in the double humidity of open water and Florida sun. We arrive with OEM or CGI-equivalent weatherstripping and rollers on the truck, and we measure every opening twice before we order anything. Dale grew up in Kendall and trained at Miami Dade College’s vocational program, reading rough openings the way a doctor reads an X-ray. That discipline travels with every job we take in Windermere.
Common CGI Windows & Doors Problems We Solve in Windermere
- Deflection-driven seal failure around mullions. Oversized CGI picture windows on lake-facing elevations take wind fetch off the Butler Chain that inland homes never see. The sash deflects, the seal compound around the mullions breaks down, and you get fogging or visible moisture between the panes. We replace the failed IG unit and re-bed the mullion joints with material spec’d for the wind load on that specific elevation.
- Corroded stainless roller pins and track delamination in pocket sliders. Windermere’s humidity sits higher than inland Orange County because of the 13 interconnected lakes. Stainless pins that would last fifteen years in Ocoee will pit and bind in five or six on a lakefront pool deck. We replace rollers with OEM or CGI-equivalent hardware and check the track for delamination before we call the job done.
- Sills corroding on early-2000s CGI installs. We see this a lot on custom builds from 1998 through 2005. The original sills were not always bedded with the drainage plane current code requires, and lake moisture finds its way in. We pull the unit, rebuild the sill pan, and reinstall with proper flashing.
- Out-of-square frames on oversized fixed windows. Wind-driven rain and years of thermal cycling will bow a large fixed picture window out of true. The glass still looks fine, but the frame is no longer square, which means the weatherstripping will never seat right again. We order custom replacements to the exact sightlines rather than trying to shim a square unit into a parallelogram opening.
- Delaminating impact glass. When laminated impact glass begins to delaminate, the fix is not a seal job. It is a replacement unit. On lakefront Windermere homes, we do not push part-only fixes when the glass itself has been compromised, because a delaminated lite will not hold under the wind load it was rated for.
CGI Service in Windermere: What Local Conditions Mean for Your Equipment
Windermere is the only municipality in Orange County where lakefront setbacks for the Butler Chain require structural engineering sign-off on full-frame CGI impact replacements. That is not a rule we invented to make the job bigger. It exists because many second-story window walls on these lakefront custom homes are cantilevered out over water, and the original headers were sized for standard insulated glass, not the additional dead load of laminated impact glass. When we replace a CGI picture window on a home like this, the engineer checks the header, the cantilever, and the connection points before we order the unit. That is a Windermere-specific step that does not apply in Winter Garden or Ocoee, where Cgi repair in Ocoee follows simpler inland protocols, and it is one reason full-frame impact work here runs longer and costs more than a standard swap. We handle the engineering coordination, the permit, and the inspection all the way through final sign-off.
CGI Models & Products We Service in Windermere
We service the full CGI line that shows up in Windermere homes: Estate Series fixed and casement windows, Classic Series single-hungs and sliders, the 1500 Series sliding glass door, and the 9010 Series single-hung. Our parts approach is simple: we use OEM or CGI-equivalent weatherstripping, rollers, and hardware, and we stock the common wearing parts for Windermere’s older CGI installs so we are not waiting on a shipment for a roller replacement. When impact glass has failed or delaminated, we do not band-aid it. We order the correct replacement lite from CGI’s distribution network and schedule the swap around the homeowner’s timeline. For Windermere lakefront homes where full-frame replacement is required, we quote manufacturer lines side by side on paper so you see exactly what you are buying. Visit our CGI sales & service page for the full scope of what we handle.
CGI Service Pricing in Windermere
| Service | Typical Range in Windermere |

Windermere pricing runs higher than neighboring cities for two reasons: the custom dimensions on lakefront estates mean most replacement units are special-order rather than stock, and the engineering sign-off on cantilevered window walls adds a step that inland work never needs. Your free estimate includes measurements, a written line-item quote, and our assessment of whether a repair or replacement is the honest call. Call (754) 238-2201 to schedule yours.

FAQs - CGI Windows & Doors in Windermere
Yes, in almost every case. CGI’s current impact-rated units are available in the same frame profiles and sightlines as the older non-impact Estate Series, which means the exterior appearance stays consistent. The interior glass will be slightly thicker because laminated impact glass is two lites bonded with an interlayer, but the frame dimensions and reveal lines can be matched. The bigger issue on lakefront homes is structural: if your existing openings were framed for standard glass, the added dead load of laminated impact glass may require header reinforcement. In Windermere, lakefront setbacks on the Butler Chain also require structural engineering sign-off before we can pull the permit. We coordinate that engineering review as part of the quote. Call (754) 238-2201 and we will walk you through what your specific home needs.
It depends on the specific product line and the year it was manufactured. CGI’s heritage is Miami-Dade, and many of their current impact products are tested and approved under both Miami-Dade County and the Florida Building Code. While we focus on Windermere, similar product approval diligence applies to our Apopka Cgi service work. This matters for Windermere because Orange County enforces FBC, not Miami-Dade’s stricter NOA process, but lakefront homeowners who want the highest wind-load rating should check the product approval on the specific CGI model being quoted. When we quote a replacement, we provide the product approval number and the design pressure rating in writing so you can verify it yourself before you sign. Call (754) 238-2201 for a quote that spells all of this out on paper.
Because the stainless roller pins on multi-panel CGI sliders corrode from the inside out in Windermere’s humidity, and cleaning the track does nothing for a pin that is pitted and binding inside the roller housing. The lakes raise local humidity enough that stainless hardware that would hold up in inland Orange County fails years earlier here. The fix is replacing the roller assemblies, not lubricating them. We stock OEM and CGI-equivalent rollers for the common CGI slider models in Windermere and can usually complete a roller replacement on the first visit. Our Oakland Cgi service team uses the same stocking approach for fast repairs there. Call (754) 238-2201 and we will diagnose it over the phone.
Yes. CGI custom finishes are available through their distribution network, and we have spec’d that exact combination, white exterior with wood-tone interior, on Windermere homes for HOA approval. The lead time runs longer than a standard finish, typically a few weeks, because the units are run to order rather than pulled from stock. We submit the product spec sheet and color samples to your HOA or architectural review board as part of the process, and we register both warranty layers in writing before the truck leaves the driveway. If the HOA needs documentation, we handle that. Call (754) 238-2201 to get the spec package started.
Realistically, four to seven weeks from measurement to completed install. The unit itself is custom-ordered because Windermere’s lakefront homes rarely have standard-size openings, and CGI’s lead time on non-standard dimensions runs three to five weeks. Add in the structural engineering sign-off that Orange County requires for lakefront setbacks on the Butler Chain, plus the permit review, and you are looking at the timeline above. The actual install day is usually one day, sometimes two if we are rebuilding stucco reveals or replacing a corroded sill pan. We will give you a written schedule before you commit. Call (754) 238-2201 for an exact timeline on your specific windows.
