Custom Windows & Doors in Union Park - Free In-Home Measure, Written Price

Fast, Reliable Custom Windows & Doors Across Union Park

Custom window and door work in Union Park almost always starts the same way: an opening that doesn’t match anything in a catalog. The homes here, mostly concrete-block tract builds from the 1970s through the early 1990s, were framed around narrow aluminum units that have spent forty or fifty years under Central Florida sun. When those openings need something better, a stock replacement won’t fit right, won’t seal right, and won’t pass Orange County wind-mitigation inspection. Our Custom Windows & Doors team handles the full-frame tear-outs, the custom buck framing, and the millwork that this housing stock actually requires. We measure every opening twice, quote manufacturer lines side by side on paper, and register both warranty layers in writing before the truck leaves your driveway.

Why TruePane Windows & Doors Is Union Park’s Preferred Custom Windows & Doors Company

We’re not the cheapest bid in Union Park, and we’ve never tried to be. We’re the company homeowners call after a pocket insert fails to stop air leakage, or after a big-box install leaves them with a door that binds in July. Our founder, Dale Kessler, is a second-generation glazier who started TruePane in 2008 with one rule on the whiteboard: if the pane is not true, the job is not done. That rule still governs every custom window and door we set in Union Park.

Our technicians are background-checked and uniformed. They work in your home the way they’d work in their own mother’s. We’re an authorized installer for more than a dozen manufacturer lines, including, PGT, and CGI. When we quote a custom job, you see the options on paper, side by side, with actual numbers, not a sales pitch over the phone. And every job carries the Done Right Promise: if it’s not done right, we make it right. No paperwork fights, no arguing.

Union Park sits in unincorporated Orange County, which means permitting for custom window and door replacements runs through the county building department, not a municipal office. We handle that process on every job. It’s not an add-on service. It’s part of doing the work correctly.

Our Custom Windows & Doors Services in Union Park

Most of what we do in Union Park falls into three categories: custom shape windows, architectural grilles and SDLs, and oversized glass panels. Here’s how each one plays out in this specific housing stock.

Custom Shape Windows

Union Park’s 1970s and 1980s tract homes sometimes surprise people. A rounded-top window on a front elevation, an angled unit in a stairwell, a half-round over a door that’s been there since 1983. When those fail, which they do after four decades of UV exposure breaking down glazing seals, you can’t order a stock replacement. We build custom shape windows to the exact rough opening, with frames rated for Orange County’s design wind speeds and glazing that actually handles Central Florida heat. The price for a custom shape window in Union Park typically runs $850 to $2,400 per unit, depending on size, shape, and whether impact-rated glass is required for your wind-mitigation report.

Architectural Grilles & SDLs

Simulated divided lites, or SDLs, give a window the look of individual panes without sacrificing insulation. In Union Park, where many original windows were true divided lites with single-pane aluminum frames, homeowners often want to keep that traditional look while gaining the thermal performance of a modern insulated glass unit. We spec SDL patterns to match the original sightlines precisely, so the new windows read as original to the house but perform like a 2026 build. Grille and SDL work adds roughly $140 to $380 per window, depending on the pattern and whether it’s applied to one side or both sides of the glass.

Oversized Glass Panels

Concrete-block construction in Union Park means some openings are genuinely large, especially on rear elevations facing backyards and patios. Homeowners here are increasingly replacing old aluminum sliders with fixed oversized glass panels to open up sightlines. This work requires engineering that accounts for wind load on a wide span, plus careful handling, because a single oversized panel can weigh several hundred pounds. A custom fixed glass panel in Union Park typically runs $1,800 to $5,500 installed. The biggest variable is whether the opening needs structural reinforcement, which it often does on 1970s block walls.

Trusted Brands We Service in Union Park

We’re an authorized installer for more than a dozen manufacturer lines, and for Union Park customers we regularly work with PGT, CGI, and Ply Gem for impact-rated and energy-efficient custom units. We also service and replace existing windows and doors from nearly every major brand, regardless of who did the original install. If you have a Marvin unit with a failed seal or a Pella door that won’t latch clean, we can source the parts, order replacement glass, and get it set correctly. We keep common components in stock locally, which shortens turnaround on service calls for Union Park homeowners. If a part has to be ordered from the manufacturer, we tell you that upfront and give you a real timeline.

Common Custom Windows & Doors Problems We See in Union Park Homes

• Full-frame tear-outs, not pocket inserts. Union Park’s original 1970s-1990s tract homes are overwhelmingly concrete-block with masonry openings sized for narrow aluminum frames. Custom window and door replacements typically require full-frame tear-outs with custom buck framing, not simple pocket inserts, to meet Orange County’s wind and thermal code requirements. A pocket insert can’t correct a rotted sill pan or a buck that’s out of square.
• Jalousie windows that cannot be saved. In Union Park’s oldest blocks, jalousie windows still appear regularly on Florida rooms and secondary bedrooms. Those horizontally louvered glass slats contribute near-zero insulation value in Central Florida’s 90°F+ summers and fail every current wind and energy code provision. No repair or retrofit exists. A full-frame replacement is the only legal and practical path.
• Aluminum frame oxidation and seal failure. Union Park’s inland Central Florida climate delivers intense year-round UV radiation that degrades vinyl glazing seals and causes aluminum frames to oxidize and pit faster than coastal salt air alone would suggest. Once the seal fails, the window fogs, loses its insulating gas, and starts leaking air. Custom replacements solve this with low-E glass and argon fill, not another coat of caulk.
• Wood door jambs and sill pans swelling from storm cycles. The daily wet-season cycle of torrential afternoon thunderstorms followed by rapid drying causes wood door jambs and sill pans to swell, rot, and lose their weather seal within a few years of any moisture intrusion. On 1970s-era homes, we regularly see front doors that won’t latch in August because the jamb has swollen closed. Custom millwork and full-frame door replacements are the lasting fix.

The Local Reality Behind Custom Work in Union Park

Union Park’s original tract homes are concrete-block, and the masonry openings were sized for narrow aluminum frames that were standard in the 1970s and 1980s. That matters more than most homeowners realize. A modern window or door frame is physically thicker than the old aluminum profile it replaces, which means the rough opening often needs to be rebuilt with pressure-treated buck framing just to accept the new unit properly. This is not optional work. Orange County’s building department reviews wind and thermal code compliance on every permit, and if the buck is undersized, the inspector will flag it.

The wind-mitigation angle is the other piece. Union Park is not in the High-Velocity Hurricane Zone, but Orange County homes still face design wind-speed requirements that mandate properly rated window and door assemblies. Homeowners here often discover this only when they try to update their wind-mitigation inspection report to claim the insurance credit. A custom replacement that’s not rated and documented won’t get you the discount. We register both manufacturer warranty layers in writing before the truck leaves, and we provide the documentation your wind-mitigation inspector needs. In fact, homeowners’-insurance wind-mitigation credits are one of the biggest drivers of custom window and door replacement in Union Park, right alongside comfort and the fact that the original units are simply worn out.

On a 1983 concrete-block home off Hiawassee Road, our crew replaced a failing jalousie window on a Florida room with a custom-sized casement unit using impact-rated glazing and a fusion-welded frame. The old louvered sash had no weatherstripping and leaked during every afternoon thunderstorm, and the new unit required rebuilding the rough opening with pressure-treated buck framing to achieve the required U-factor and SHGC for Orange County’s wind-mitigation inspection. That’s a typical job here. It’s not a simple swap.
