Fast, Reliable Custom Windows & Doors Across Union Park
A custom window or door job in Union Park runs anywhere from $1,800 for a single architectural grille unit up to $25,000+ for a full curtain wall or oversized glass panel system. Most mid-range custom projects on the CBS ranch homes that define this community land between $4,500 and $12,000. We’re TruePane Windows & Doors, and we’ve been setting custom glass and millwork in unincorporated Orange County long enough to know one thing cold: the permit desk at the Orange County Building Division sets the schedule, not the labor. Call (813) 320-9346 for a free estimate, and we’ll walk you through what’s actually buildable on your lot.
Union Park is different from Orlando or Oviedo, and it matters. Every custom window and door replacement here routes through Orange County Building Division, not a city hall. That changes the approval workflow, the documentation you need before ordering glass, and the realistic timeline. We plan around that reality from the first measurement.
Why TruePane Windows & Doors Is Union Park’s Preferred Custom Windows & Doors Company
TruePane was founded in 2008 by Dale Kessler, a second-generation glazier who grew up around window and door shops and learned early that out-of-true installs and voided warranties were problems worth fixing permanently. Years of combined community service runs through this company. We hire local, train apprentices into journeymen, and act like a company that plans to be in Union Park thirty years from now. That’s not a slogan. It’s how we bid, how we staff, and how we answer the phone.
Union Park homeowners call us because we know the housing stock. The single-story CBS ranch homes built here between the late 1960s and mid-1980s have specific rough opening dimensions, specific header conditions, and specific failure modes we’ve seen hundreds of times. A background-checked, uniformed technician measures every opening twice, quotes manufacturer lines side by side on paper, and registers both warranty layers before the truck leaves the driveway. That’s The Keystone Standard, and it’s written into every job we do.
When you call (813) 320-9346, a live person answers. Not a voicemail tree, not a callback form, not a regional call center. That matters when you’re trying to schedule a permit inspection or confirm a glass order. Our customers in Union Park know they can reach a person at 2 p.m. on a Tuesday or 2 a.m. on a Saturday.

Our Custom Windows & Doors Services in Union Park
We focus on the work most Custom Windows & Doors contractors in this market won’t touch. Custom shapes, architectural grilles, oversized glass panels, and full glazing systems for residential and commercial work. If you’re in Union Park and the opening is not a standard size, this is what we do.
Custom Shape Windows
Round-tops, arches, trapezoids, gable-end glass, and geometric transoms. Union Park ranch homes often have original rectangular aluminum openings that can be reframed to accept a custom arch or eyebrow window, but the structural openings in concrete block walls require careful header work. We measure the true rough opening, specify the exact radius or angle with the manufacturer, and file the Orange County product approval docs before the glass is fabricated. A custom shape window in Union Park typically runs $1,800-$4,500 installed, depending on the radius, glass package, and whether the opening requires reframing.

Architectural Grilles & SDLs
Simulated divided lites and architectural grilles are detail work. Done wrong, the muntins look chunky and the sightlines are off. Done right, a SDL package on a Marvin or Andersen unit reads like true divided light at a fraction of the cost. We quote these side by side on paper so you see the true SDL, the spacer bar, and the glass package in the same document. On a Union Park CBS ranch, a SDL upgrade adds $400-$1,200 per unit depending on the pattern and profile. Most homeowners doing a whole-house replacement add this to the front elevation only, where it shows from the street.

Oversized Glass Panels
Fixed picture windows, floor-to-ceiling glass, and multi-panel sliding walls. In Union Park’s inland climate, oversized glass needs a low-E coating and a warm-edge spacer to keep the July humidity from fogging the unit. We specify argon or krypton fill depending on the size and wind-load requirements. A single oversized fixed panel, 60 to 96 inches wide, typically runs $2,800-$7,500 installed. The wide range reflects glass thickness, impact versus non-impact, and whether the existing CBS rough opening needs widening, which is common on 1970s-era homes with narrow window bands.

Commercial Storefront Glazing & Curtain Wall Systems
Union Park’s commercial strips along East Colonial Drive and the retail clusters near Alafaya Trail include storefronts that are 30 to 50 years old, with aging aluminum frames and single-pane glass. We replace storefront glazing, aluminum entry systems, and full curtain wall sections on commercial buildings. Commercial glazing in Union Park requires Orange County product approval and, on occupied buildings, phased installation to keep the business open. Curtain wall replacement on a Union Park storefront typically starts around $12,000 and goes up from there, driven by the system, the glass package, and the phasing plan.

Custom Windows & Doors in Union Park: The Permitting Reality
This is the paragraph that matters if you live in Union Park and you’re pricing a custom job. Union Park is unincorporated Orange County. That means every window and door permit routes through the Orange County Building Division, not a city hall like Orlando or Oviedo. Approved product specs, FBC wind-load compliance documentation, and structural calculations must be filed before the first cut. Your designer may specify a window, but Orange County decides whether that window is approved for your block home.
We handle this end to end. Before we order a single piece of glass for a Union Park project, we verify the product approval number, pull the structural calcs, and file the permit documents. You don’t chase that paperwork. We do.
Trusted Brands We Service in Union Park
We are an authorized installer for more than a dozen manufacturer lines, including Andersen, Pella, Marvin, Milgard, Jeld-Wen, PGT, CGI, and ES Windows. We also work with ECO Window Systems on high-end architectural projects in Union Park. Because we stock local parts and maintain manufacturer relationships across the board, we can often get replacement sashes, glass units, and hardware faster than a contractor who orders through a third party. When you’re replacing an oversized panel and the seal fails under warranty, the speed of the parts matters. We register both warranty layers in writing, with durations stated, on every job.
Common Custom Windows & Doors Problems We See in Union Park Homes
- Original aluminum jalousie windows in converted Florida rooms: These are common in Union Park rear additions and enclosed patios. The jalousie panels are completely non-compliant with current Florida Building Code energy and structural requirements. A simple glass swap is not legal. The entire frame must be pulled and a compliant unit installed with approved product specs filed to Orange County.
- Custom architectural glass specified without Orange County product approval docs: We see this on designer-driven projects. The designer specifies an imported glass system, the permit gets filed, and Orange County rejects it because the product approval number is missing or expired. The long-lead fabrication window passes, and the install date moves. We catch this before ordering.
- Oversized panels that arrive factory-sized for the wrong rough opening: CBS ranch homes in Union Park have specific rough opening dimensions that rarely match modern factory defaults. If the rough opening is not measured twice and the structural condition of the header is not checked, the panel arrives oversized or undersized. That triggers reframing after the fact, which drives cost and schedule overruns.
- High-end wood jamb assemblies that swell within one Union Park summer: The inland humidity here is hard on wood jamb material. A beautiful mahogany or oak jamb assembly installed without proper flashing and sealing will swell, the seal will break, and the insulated glass unit will fog. We flash jambs with butyl tape and specify moisture-resistant jamb materials on exterior applications.
Pricing for Custom Windows & Doors in Union Park, FL
Here are honest numbers for the Union Park market, not vague ranges pulled from a national site. A single custom shape window in Union Park runs $1,800-$4,500. Architectural grilles and SDLs add $400-$1,200 per unit. A single oversized fixed panel runs $2,800-$7,500. Commercial storefront glazing starts around $12,000. A full curtain wall system on a Union Park commercial building starts at $25,000 and goes up quickly with system type and glass package. Residential whole-home custom replacement on a CBS ranch typically lands between $15,000 and $40,000, driven by window count, glass package, impact requirements, and whether any openings need structural reframing.
What moves the price in Union Park specifically? The permit path. Unincorporated Orange County requires product approval docs and wind-load documentation on every custom window and door. That is a fixed cost and a fixed timeline. We quote line-item, in writing, before ordering anything. The price does not change once work starts, unless you ask us to change the scope. No change orders, no surprises. Call (813) 320-9346 for a free estimate. We measure, we quote, and we register your warranties before the truck leaves.

FAQs - Custom Windows & Doors in Union Park
Because Union Park is unincorporated. Orange County Building Division reviews and approves every window and door permit, including product approval numbers, FBC wind-load compliance, and structural calculations. You cannot legally order custom glass and then file the permit later. The permit must be approved with the product specs on file before fabrication begins. We prepare and file all of that documentation for you. Call (813) 320-9346 and we’ll start with a measurement and a permit review.
No. Original aluminum jalousie frames from the 1970s are not compliant with current Florida Building Code energy or structural requirements. Installing new glass into a non-compliant frame does not fix the underlying problem and will not pass an Orange County inspection. The entire frame must be pulled and replaced with a compliant unit. We do this regularly on Union Park Florida rooms. A replacement typically runs $1,800-$4,500 depending on the opening size and glass package. For an exact quote, call (813) 320-9346.
We work directly with the designer and the architect. Before anything is ordered, we verify the specified product has a valid Orange County product approval number. We check the rough opening dimensions against the factory specs. We coordinate the lead times. On a recent job near Union Park Elementary, our crew retrofitted a converted Florida room off a 1970s CBS ranch where the original aluminum jalousie panels had no FBC-compliant straps. We pulled the old frames, flashed the jambs with butyl tape, installed a Marvin casement unit with low-E insulated glass and argon fill, then submitted the approved product specs to Orange County before the inspector walked. That is how coordination works when it is done right. Call (813) 320-9346 to start.
Your neighbor’s contractor gave a labor estimate because he hadn’t priced the materials, the permit documentation, or the long-lead fabrication. At TruePane, we fix the price in writing before we order anything because we know what the materials cost, what Orange County requires, and what the schedule actually is. The 90-Day Done Right Promise applies to the workmanship. The Keystone Standard registers both warranty layers in writing before the truck leaves the driveway. A labor estimate that balloons later is not a square deal. We don’t work that way. Call (813) 320-9346 for a fixed, line-item quote.
In most cases, no. Interior courtyards that are fully enclosed by the home’s exterior walls are not exposed to wind-driven debris or direct wind load in the way an exterior elevation is. That said, Orange County Building Division makes the final call based on the building envelope and the orientation. We verify wind-load zones and FBC exposure categories before recommending a glass package. In some cases, laminated glass is required for safety glazing even when impact rating is not required. For a clear answer on your specific courtyard, call (813) 320-9346 and we’ll have a technician look at it.
