CGI Windows & Doors in Lake Mary, FL | TruePane Windows & Doors
TruePane Windows & Doors provides independent CGI window and door service throughout Lake Mary, including repairs, glass replacement, and full installations. We’re not a manufacturer-authorized dealer, which means we answer to you, not a quota. The one thing that makes our CGI work different here is the dual paperwork: every Lake Mary job sits inside both Seminole County’s permitting system and an HOA’s architectural review, and we’ve learned how to pull both sets of requirements before we ever quote a frame. Call (813) 320-9346 for a free estimate.
Why Lake Mary Residents Choose Us for CGI Service
We’ve been replacing and repairing CGI Windows & Doors in Lake Mary’s concrete-block homes long enough to know which Sentinel Series products clear Seminole County wind-load documentation without a second look, and which frame colors Heathrow’s Architectural Review Committee will actually sign off on. That’s not something you learn from a spec sheet. It comes from showing up, measuring twice, and paying attention when an HOA sends a homeowner back to the drawing board because the finish didn’t match the original builder palette.
Dale Kessler, our owner, started in this trade at Hillsborough Community College’s construction technology program, then spent the better part of two decades setting and sealing windows across Central Florida. His rule hasn’t changed: if it needs to be in writing to be true, we will put it in writing. That’s why we register both warranty layers on every CGI job before the truck leaves your driveway.
Our technicians arrive background-checked, uniformed, and prepared to work with OEM CGI hardware and insulated glass units whenever they’re available. When an older CGI frame is discontinued, we source marine-grade replacement seals and stainless hardware that match the original thickness and finish. Nothing gets patched with parts that compromise the wind-load rating.
Key Takeaways
- Independent CGI service, not manufacturer-affiliated or authorized.
- OEM CGI parts used whenever available; spec-matched aftermarket for discontinued frames.
- We pull Seminole County and HOA requirements before quoting any Lake Mary job.
- Both warranty layers registered in writing on every install, per The Keystone Standard.
- 90-Day Done Right Promise on workmanship. No paperwork fights.
Common CGI Windows & Doors Problems We Solve in Lake Mary
- White oxidation along the bottom rail of aluminum frames. Lake Mary’s inland sun beats hard on south- and west-facing elevations. We regularly see CGI aluminum frames on those exposures showing white powdery corrosion within 8 to 12 years. The humidity cycling doesn’t help; it drives moisture into micro-scratches and accelerates the breakdown. We’ll assess whether the frame can be cleaned, prepped, and refinished or if the structural integrity calls for a replacement sash.
- Fogged or hazy insulated glass units (IGU seal failure). Homes built between the mid-1980s and mid-2000s across Lake Mary often have original CGI double-pane units that start showing interior fogging at the 10-to-15-year mark. South and west elevations fail first. When the seal goes, the thermal performance is already gone. We replace the IGU with a Florida Product Approved CGI sash so the rating stays intact.
- Roller and caster wear on CGI sliding glass doors near pool decks. Trapped moisture around screen enclosures and pool decks corrodes tracks and wears rollers faster than you’d expect. A CGI slider that once glided starts to grind and bind. We replace rollers, clean and realign tracks, and correct any corrosion before it spreads into the frame itself.
- Sagging or misaligned casement hinges in larger window openings. Heathrow homes are known for bigger window-to-wall ratios. That means more glass, more weight, and more torque on the hinges of CGI Estate Series casements. Over time, the hinges sag and the sash no longer seats square. We replace the hardware, realign the frame, and make sure the window closes tight enough to keep its rating.
- Failed or leaking weatherstripping on original CGI frames. The daily heat-and-humidity cycle in Lake Mary is rough on gaskets and sweeps. Once weatherstripping hardens or tears, air and moisture get through. We use OEM or matched-thickness replacement seals and recheck the frame’s overall seal performance before we call the job done.
CGI Service in Lake Mary: What Local Conditions Mean for Your Equipment
Nowhere is the Lake Mary difference sharper than in Heathrow and the surrounding gated communities. The Architectural Review Committee there maintains a documented palette of frame colors, bronze and white being the two that matter for existing homes. That may sound like a detail. It’s not. A homeowner in Heathrow who replaces an original bronze CGI Estate Series casement with a standard off-the-shelf white vinyl window can receive a mandatory re-order from the HOA. The work doesn’t just fail compliance; it costs thousands to undo. We pull the community’s ARC guidelines before we quote any Lake Mary job. A mile north in Cgi in Sanford, that step rarely applies. In Lake Mary, it’s the difference between work that passes and work that gets torn out.
This matters doubly for CGI owners because the frame finish isn’t cosmetic. It’s tied to the product’s Florida Product Approval documentation. Lake Mary’s inland location means we’re outside Miami-Dade’s High Velocity Hurricane Zone, but Seminole County wind-load code still requires product approval paperwork on every replacement window and door. A bronze CGI frame with ARC approval but no matching county documentation fails just the same as a white one that never got ARC sign-off. We handle both. That’s not a bonus service here; it’s baseline competence for any Lake Mary replacement.
CGI Models & Products We Service in Lake Mary
We service the full range of residential CGI lines common across Lake Mary and nearby communities, including Cgi repair in Altamonte Springs, the CGI Sentinel Series Impact Windows, the CGI Estate Series Windows, and the CGI Estate Series Sliding Glass Doors. We also work on the CGI Commercial Series Storefront, which shows up on a handful of Lake Mary office and retail properties.
Our parts stance is simple: OEM first. When CGI hardware and insulated glass units are available, we use them. For older discontinued frames where OEM stock is gone, we source identical-thickness marine-grade aftermarket seals and stainless hardware that match the original specifications. We stock common CGI roller sets, casement hinge kits, and gasket profiles locally so our turnaround on Lake Mary and Cgi service in Winter Springs calls stays tight. If a frame or glass unit can’t be restored to its tested rating, we’ll tell you straight and recommend a full replacement rather than a cosmetic repair that puts your home’s wind-load rating at risk.
CGI Service Pricing in Lake Mary
CGI service pricing in Lake Mary depends on what failed and whether the repair restore the window or door to its original tested rating. Here’s what we typically see:
- Insulated glass unit replacement on a CGI double-pane: $350-$700 per unit, depending on sash size and low-e configuration.

FAQs - CGI Windows & Doors in Lake Mary
Yes. Seminole County requires a building permit for any replacement window or door, even when the opening size and style don’t change. The county also requires Florida Product Approval documentation on the replacement product. We pull the permit and submit the product approval paperwork as part of every Lake Mary replacement. In HOA-governed communities like Heathrow, ARC approval is an additional requirement above and beyond the county permit. Call (813) 320-9346 and we’ll walk you through what applies to your street.
In most cases, yes, as long as the sash and frame are structurally sound and the replacement IGU carries the matching Florida Product Approval documentation. We replace failed CGI double-pane glass with OEM IGUs when available, or spec-matched units for discontinued models. If the frame itself shows bottom-rail corrosion or hinge wear beyond repair, a glass-only fix becomes a temporary measure, and we’ll tell you before you spend on it.
Usually because the denial comes down to submission completeness, not the product itself. The Heathrow ARC approves bronze CGI windows when the finish, grid pattern, and glass type all match the original builder documentation for that specific home. A neighbor’s approval doesn’t guarantee yours if the home was built in a different phase or under a different builder spec. We pull the ARC guidelines for your address before quoting, and we submit the written approval request with the exact product details the committee needs. If it needs to be in writing to be true, we will put it in writing.
No. Seminole County code requires replacement windows to meet current Florida Energy Conservation Code minimums for SHGC and U-factor, but it does not mandate impact-rated products for homeowners who only want improved energy performance. That said, many Lake Mary homeowners choose impact-rated CGI Sentinel Series units anyway because they reduce insurance premiums and meet the wind-load documentation requirements permanently. We’ll quote both paths side by side on paper so you can see the difference in upfront cost and long-term value. Call (813) 320-9346 for an exact quote.
Yes, and in Lake Mary that’s one of the more common calls we get. Hard-to-open CGI sliders around pool decks and screen enclosures usually mean roller wear, track corrosion, or both. We replace the rollers, clean and realign the tracks, and address any frame corrosion before it spreads. No glass damage doesn’t mean no problem; a dragging slider is a warning sign, not a nuisance. The sooner you catch it, the cheaper the fix. Call (813) 320-9346 and we’ll assess it on the first visit.
