CGI Windows & Doors in Altamonte Springs, FL | TruePane Windows & Doors
We provide independent CGI windows and doors service across Altamonte Springs, from ThermaFit sash rebuilds to full-frame 8700 slider replacements, and we also offer CGI service in Casselberry. The one thing that makes our CGI work here different is simple: we show up at the first estimate with pre-filled condominium association consent forms and product spec sheets, because in Altamonte Springs, no window or door job in a condo moves without COA sign-off and a Seminole County permit. If you’re living in one of the older complexes along SR-436 and your CGI units are fogging, dragging, or binding, call (954) 280-4413 and we’ll walk you through the whole process before you spend a dime.
Why Altamonte Springs Residents Choose Us for CGI Service
We have rebuilt more CGI windows and doors in Altamonte Springs condos than any independent shop we know. That is not a brag. It is a count of every failed ThermaFit sash we have re-glazed, every hinged patio door we have re-gasketed, and every 8700 slider we have re-hung along the SR-436 corridor, from the blocks around Cranes Roost Park down to the Altamonte Mall. Dale Kessler grew up resealing jalousie windows in South Florida humidity, went through the building trades program at McFatter Technical College, and spent two decades putting impact-rated units into coastal buildings before founding TruePane. He teaches every tech the same rule he was taught: if it is not right on paper, it will not be right on the wall. We arrive with that paperwork.
We are not authorized by CGI. We say that plainly because it matters. Independence means we stock hard-to-get CGI parts without a factory quota telling us what to push. It means when we look at a fogged ThermaFit sash, we tell you the honest repair-versus-replace math, not the number a manufacturer rep needs us to hit this quarter. And it means when a job in Altamonte Springs needs condominium association approval before the permit can be filed, we bring the consent forms to the first visit, not the third.
Beyond CGI, we are an authorized installer for more than a dozen manufacturer lines, including, PGT, and ES Windows. That breadth matters when a repair no longer makes sense and you want side-by-side quotes on paper before choosing a replacement. We are happy to show you that comparison. It is a square deal, and it is how we have worked since 2008.
Common CGI Windows & Doors Problems We Solve in Altamonte Springs
- Fogged ThermaFit sashes from seal failure. In Altamonte Springs, the intense year-round UV and daily summer thunderstorms hammer west-facing condo units especially hard. We regularly see ThermaFit vinyl impact windows near Cranes Roost Park with interior fogging after eight to twelve years of direct afternoon sun. The seal goes, moisture gets in, and the glass starts to look like a shower door. We replace the failed sash with a genuine CGI unit so the impact rating and the thermal performance both hold.
- Frame oxidation on hinged patio doors from the 2000s. Older lanai thresholds in Altamonte Springs pool water during summer downpours, and that standing water creeps into the bottom corners of CGI hinged patio doors. The aluminum oxidizes, the corner joints swell, and the door starts to bind. We can often re-gasket and repair the frame if caught early. If the oxidation has compromised the structural corner, we tell you straight and quote a replacement door.
- Dragging CGI 8700 sliding doors in original 1980s condo units. The heavy impact glass in an 8700 slider sits on roller assemblies that wear down after decades of use. In aging Altamonte Springs buildings, we see doors that jump the track, drag across the sill, and take two hands to move. That is a safety issue, not just an inconvenience. We replace rollers with genuine CGI parts matched to the original track and re-hang the panel so it moves with one finger.
- Binding multi-point locks on French doors. Condominium slabs settle over decades, and when they do, the frames shift a fraction of an inch. That fraction is enough to misalign a CGI multi-point lock so the deadbolts will not throw without forcing the handle. We fix the alignment, replace worn lock kits when needed, and make sure the door actually locks the way it was designed to.
- Leaking exterior flanges after caulk failure. The caulk around a window flange does not last forever, especially under Central Florida’s UV load. When it fails, water finds its way behind the frame and into the drywall. We pull the old caulk, inspect for hidden rot or damage, and re-caulk with a sealant rated for Florida exposure before the leak becomes a mold problem.
CGI Service in Altamonte Springs: What Local Conditions Mean for Your Equipment
Here is the thing most contractors will not tell you until they are already behind schedule. Altamonte Springs is one of the few Central Florida cities where every window or door replacement in a condominium requires both a Seminole County building permit and written condominium association approval before work starts. That dual-track process does not exist in the single-family suburbs immediately north of SR-436 or in areas with CGI service in Longwood. If a contractor shows up unprepared, a straightforward CGI window swap can sit idle for a month waiting on the next board meeting. We learned this years ago, and we adjusted how we work because of it. Our techs arrive at CGI estimates in the Altamonte Mall corridor complexes with pre-filled COA consent forms and product spec sheets already in hand. In a seventh-floor unit at The Enclave at Altamonte, our crew replaced two failed CGI ThermaFit casements that had blown seals and were dripping condensation into the drywall after summer storms. We pulled the old sashes, reset new genuine CGI impact sashes with fresh glazing tape, re-caulked the exterior flanges, and then walked the COA approval form down to the management office so the board could sign before we filed the Seminole County permit. The condo’s maintenance log now shows those units will not leak again for another decade. That is how the dual-permit reality should be handled, and it is how we handle every CGI job in Altamonte Springs.
CGI Models & Products We Service in Altamonte Springs
We service the full CGI residential line: the ThermaFit Series vinyl impact windows, the Estate Collection aluminum impact windows and doors, the 8700 Series sliding glass doors, and the Classic Collection single-hung and casement units. When a repair must match existing impact glass and structural frames, we use genuine CGI replacement sashes, rollers, and multi-point lock kits. For cosmetic hardware and weatherstripping, we often specify aftermarket parts that meet Florida Product Approval and run 20 to 30 percent less. We keep common CGI parts stocked locally so most Altamonte Springs service calls finish in a single visit. If a unit is older than twelve years with seal failure or track damage, we show you repair versus full-frame replacement costs side by side before you spend anything. You deserve to see the math on paper, and we put it there.

FAQs - CGI Windows & Doors in Altamonte Springs
Yes. In Altamonte Springs, every window or door replacement in a condominium requires written COA approval before a Seminole County building permit can be filed, regardless of who does the work. We bring pre-filled COA consent forms to the first estimate so your job does not stall waiting on the next board meeting. Call (954) 280-4413 and we will walk you through the exact sequence for your building.
We replace the failed sash with a genuine CGI unit. The fogged glass cannot be un-fogged, but the frame stays in place and the impact rating is preserved when the new sash is matched correctly. On a ThermaFit unit older than twelve years, we will also show you the full-frame replacement cost so you can compare before deciding. Estimates are free.
Yes. All replacement windows and doors in Seminole County must carry Florida Product Approval numbers under the Florida Building Code, and every CGI impact door we install carries that approval. The wind-speed design requirements inland are lower than coastal counties, but the product approval requirement is the same. We verify FL# documentation on every unit before it goes in.
Seal failure on west-facing ThermaFit sashes. Direct afternoon sun on units near Cranes Roost Park and the Altamonte Mall corridor breaks down the seal after eight to twelve years, and the interior glass fogs. We replace more of those sashes in Altamonte Springs than any other single CGI repair. Call (954) 280-4413 for an exact quote on your unit.
Both. We use genuine CGI replacement sashes, rollers, and multi-point lock kits when a repair must match existing impact glass and structural frames. For cosmetic hardware and weatherstripping, we specify aftermarket parts that meet Florida Product Approval and cost 20 to 30 percent less. We will show you both options on paper and let you decide.
