CGI Windows & Doors in Longwood, FL | TruePane Windows & Doors
CGI windows and doors in Longwood are built for impact, but the equipment still ages, shifts, and leaks like any other aluminum or laminated glass product. We service, repair, and restore CGI windows and doors across every Longwood neighborhood, from the historic village to the 1970s ranch tracts off Wekiva Springs Road. The thing that separates our CGI work here is knowing which parts fail first under Central Florida’s heat-cool cycling, and when a repair in the historic district needs a Certificate of Appropriateness before anyone touches the sash. Call (754) 238-2201 for a straight answer and a free estimate.
Why Longwood Residents Choose Us for CGI Service
We are an independent CGI service provider. We do not wear a factory patch, and we do not need one to do this work correctly. Our crews have pulled and repaired enough CGI sashes across Longwood’s concrete-block ranch tracts and the historic district to know exactly which frames, balances, and hinge sets fail under Central Florida’s thermal cycling. That knowledge comes from hands-on repetition, not a training webinar.
Dale Kessler, our owner, learned to read a rough opening the way a doctor reads an X-ray at Miami Dade College’s vocational program, and he has been measuring, sourcing, and setting windows in South Florida for going on three decades. The rule he keeps on the whiteboard still governs every CGI job we touch in Longwood: measure it right the first time, or plan on coming back. We would rather spend an extra ten minutes on the ladder than make a second trip that wastes your afternoon. When you call TruePane, a live person answers. Every time. We will tell you what we can fix, what should be replaced, and what it will cost before any work begins.
Common CGI Windows & Doors Problems We Solve in Longwood
CGI products earn their reputation in a storm, but everyday wear in Longwood exposes failures most homeowners never see coming. Here is what we handle most often:
- Fogged insulated glass in CGI Classic Series fixed panels. Longwood’s afternoon thunderstorm pressure cycles stress the perimeter seal on older glass packs, and the inland heat-cool swings break it faster than coastal salt air ever could. The result is condensation between the panes that will not wipe away. We source factory-original insulated glass packs where glazing dimensions allow, and the repair is typically done in one visit.
- Balancer and tilt-latch failures in CGI Classic Series single-hungs. The original aluminum inserts on Longwood’s 1970s ranch homes were retrofitted into channels that now collect humidity, and the pivot shoes bind inside the frame. The window either will not stay up or will not tilt in for cleaning. We replace the balances with correct-tension parts and square the channel before reinstalling the sash.
- Roller lift-off and track galling in CGI Estate Series sliding doors. Pollen, oak tassels, and daily condensation pack into the bottom runner on west-side Longwood homes, and the rollers eventually gall the aluminum track. The panel jumps the rail or jams halfway open. We pull the door, clean or replace the rollers, and flatten the track where galling has started. If the panel has twisted, we say so plainly.
- Flashing-gap mold growth around non-impact CGI inserts. Many original 1970s rough openings were never properly flashed for Longwood’s humidity, and dark streaks at the interior sill are the tell. We pull the interior stops, inspect the opening, install a full-perimeter flashing pan, and reset the unit. This is a repair, not a band-aid.
- Historic district compliance failures. In the Longwood Historic Village, a homeowner who installs a standard CGI double-hung without approval can have the permit challenged and the work flagged. We handle the Certificate of Appropriateness paperwork, match lite patterns to the original sash, and coordinate with the Historic Preservation Board before installation.
CGI Service in Longwood: What Local Conditions Mean for Your Equipment
Longwood contains one of Seminole County’s few nationally registered historic districts, the Longwood Historic Village, and that fact changes how CGI windows and doors are serviced here. The city’s Historic Preservation Board requires a Certificate of Appropriateness before any window or door replacement in the district, and the city will reject a standard double-hung vinyl insert if its muntin profile or lite pattern does not match the original wood sash. That regulatory gate does not exist in Altamonte Springs, Lake Mary, or Casselberry. Contractors who skip it and pull only a standard Seminole County building permit will have that permit challenged. What this means for CGI owners in the village is simple: the sash must be historically accurate before it can be impact-rated. Everywhere else in Longwood, the opposite problem dominates. The 1970s and 1980s concrete-block ranch tracts off Wekiva Springs Road and around Sanlando Springs are aging into mass window-replacement territory, and most of the original single-pane aluminum sliders do not meet current Florida Building Code wind-load minimums. We work both markets. The historic district demands precision and paperwork. The ranch tracts demand honest retrofit assessment and code compliance. Knowing which situation you are in before we quote saves hours and headaches.
CGI Models & Products We Service in Longwood
We service the CGI Estate Series aluminum impact windows, the Classic Series single-hungs and sliders, the Estate Series hinged and sliding glass doors, and the Sentinel Series impact windows found in newer Longwood construction. Our approach to parts is straightforward: we source factory-original CGI balances, rollers, sash locks, and insulated glass packs whenever the glazing dimensions allow, and we install high-quality aftermarket PVD-coated hinges and marine-grade weatherstripping when an OEM part is known to fail early in Longwood’s humidity. We keep common CGI rollers, balances, and weatherstripping on the truck for most Longwood jobs, which means less waiting on freight from the distributor. If you need a part we do not carry, we will tell you the lead time before we quote.
CGI Service Pricing in Longwood
CGI service pricing in Longwood depends on the model, the failure, and whether the opening is in the historic district or a standard ranch tract. Fogged glass pack replacement on a Classic Series fixed panel typically runs $280 to $520. Balancer replacement on a single-hung ranges from $180 to $320 per window. Sliding door roller replacement runs $225 to $400, and a full flashing pan installation around an existing CGI insert starts at $350. Historic district work carries an additional compliance cost because the Certificate of Appropriateness filing and board review take time and paperwork. Every quote is a written, line-item estimate, and there are no surprise charges added after the work is done. Call (754) 238-2201 to schedule a free estimate, and we will put the numbers on paper before anyone picks up a tool.

FAQs - CGI Windows & Doors in Longwood
No. A standard off-the-shelf CGI double-hung insert will usually be rejected in the Longwood Historic Village because the muntin profile and lite pattern must match the original wood sash. The city requires a Certificate of Appropriateness from the Historic Preservation Board before any permit is issued, and replacement windows must reproduce the original lite configuration. We handle that matching process, build the custom stops and divided lites as needed, and file the paperwork. Call (754) 238-2201 if you live in the village and need a CGI window replaced.
The difference comes down to tree cover and drainage patterns. Longwood’s west-side 1970s tracts sit under heavier oak canopy, and oak tassels combine with daily condensation to pack the bottom roller track on long CGI Estate Series sliding doors. Lake Mary homes tend to have newer landscaping and less debris in the runners. The fix is the same either way: pull the panel, clean or replace the rollers, and dress the track. Call (754) 238-2201 for a free estimate on a sticky slider.
Yes, in most cases. The fog is moisture between the panes caused by a broken perimeter seal, and the repair is to replace the insulated glass pack, not the entire window. We source factory-original glass packs where glazing dimensions allow, and the frame stays in place. If the frame joinery has failed or the sash is out of square, replacement becomes the honest call. Call (754) 238-2201 and we will tell you which situation applies to your window.
The Certificate of Appropriateness requires that replacement windows match the original sash in lite pattern, muntin profile, and overall proportions, and that the Historic Preservation Board reviews the application before the city issues a building permit. Standard double-hung vinyl inserts are often non-approvable in the village. We prepare the application, provide the board with the material specs and lite-pattern drawings, and handle the follow-up questions. Call (754) 238-2201 to find out whether your opening is in the historic district and what the process will involve.
It depends on the condition of the existing frame and the opening. If the original CGI aluminum frame is square, the joinery is sound, and the opening is flashed correctly, an insert is the more cost-effective route. If the frame has corroded at the corners, the rough opening was never properly flashed, or the lite pattern must change for code, full-frame replacement is the right call. We will measure the opening twice, check the frame with a straightedge, and tell you which path makes sense for your house. Call (754) 238-2201 for a free estimate.
