Fast, Reliable Window Installation Across Union Park
Window installation in Union Park runs $450 to $1,900 per opening for full-frame replacements of the original aluminum single-pane units still sitting in most of the neighborhood’s 1970s-through-1990s tract homes. The number that matters more, particularly on the older blocks off Colonial Drive and Hiawassee Road, is what the project earns you through Orange County wind-mitigation insurance discounts after permits close and the inspection passes. If your windows predate Florida’s 2002 building code, they predate the performance standard your insurance carrier now looks for, and replacement is less an upgrade than a paper trail. Call (954) 280-4413 for a free estimate on any window job in Union Park. Unlike most window companies working the east Orlando market, we pull the Orange County permit, register both warranty layers in writing, and hand you a fixed price before any glass gets ordered. The work goes through the building department, not around it, and we stand behind every install with a Done Right Promise.

Why TruePane Windows & Doors Is Union Park’s Preferred Window Installation Company
Union Park is not a gloss-over town. The homes are concrete block, the lots are tight, the storm season is real, and the customer base has lived here long enough to know when a contractor is cutting corners. The phone gets answered by a live person, 24 hours a day, every day. Not a voicemail tree, not a callback form. When a Union Park homeowner calls on a Tuesday evening because a southwest-facing picture window finally gave up its seal, they get a human being on the first ring who can schedule a real appointment. That has been the operating rule since Dale Kessler founded TruePane in 2008 on the back of a second-generation glazier’s conviction that out-of-true installs and voided warranties were problems worth fixing permanently.
Our technicians work every block in Union Park from the SR-50 corridor up to the Hiawassee/Goldenrod edge, and they treat each house as if their own mother lived there. Uniformed, background-checked, measuring every opening twice before anything gets ordered. The local knowledge matters here because so much of the housing stock was built in a short window of time using the same original aluminum extrusions, the same jalousie units, and the same builder-grade flashing. We know what’s inside the walls before the saw comes out because we’ve opened hundreds of them in this zip code. And when a homeowner tells us the aluminum frame is pitted and the glass is fogged between the panes, we already know the manufacturer, the failure mode, and the right replacement. We also know that Union Park’s proximity to major east Orange County thoroughfares means fast scheduling when you need the estimate, not endless back-and-forth with a regional dispatch desk in another time zone. Dispatch is coordinated from our Miami office; the crews doing the work serve Union Park directly and locally.
Our Window Installation Services in Union Park
Union Park’s original tract homes were built with what was cheap and available in 1970s and 1980s Central Florida. That means aluminum sliders, fixed lites, jalousie units on Florida rooms, and very little thought for thermal performance or wind resistance by today’s standards. What follows are the openings we replace most, week after week, in this neighborhood.
Casement Windows
Casement windows are the quiet workhorse of the Union Park replacement market, and we install more of them here than any other style. They crank open to catch the afternoon breeze that rollover storms leave behind, and they seal tightly against both wind-driven rain and the dry-season dust that filters through original tracks. In the Florida rooms and converted carports common on older Union Park properties, a casement assembly with a factory-applied finish and a properly flashed frame is often the first window the homeowners say actually works. A typical casement replacement in Union Park runs $550 to $1,400 per opening depending on size and impact rating.

Awning Windows
Awning windows solve a specific Union Park problem: the narrow horizontal opening up high on a 1980s block home, usually over a kitchen sink or in a secondary bath, where the original aluminum unit either leaks or will not lock anymore. Because they hinge at the top and open outward, they shed rainwater naturally, which matters on elevations that take the brunt of the daily wet-season thunderstorms. Awning replacements in Union Park generally land between $480 and $1,100 per opening, and for the house on Hiawassee with a row of original single-lites, this is a practical, quieter, and more energy-consistent upgrade.

Fixed & Picture Windows
Fixed and picture windows carry the largest glass area of any window type, and in Union Park’s southwest-facing living rooms, they soak up the most UV and heat. The original single-pane units on these elevations fail differently than sliders: the aluminum frames oxidize, the glazing seals break down under years of direct sun, and the insulating value declines to near zero. A modern fixed or picture window replacement runs $500 to $1,900 in Union Park, with variance driven by glass package, impact rating, and whether the homeowner wants a custom millwork-matched casing or a standard interior return. We coordinate with the homeowner’s architect or designer when the job calls for something beyond stock dimensions.

Single & Double Hung
Single and double hung windows remain the most common replacement style in Union Park’s older front elevations because they fit the original rough openings with minimal alteration and keep the traditional look many homeowners want. The catch is efficiency: a cheap vinyl hung unit in a 1979 Union Park block home will not perform the way a higher-DP assembly does, and the difference shows up on the wind-mitigation inspection and the summer cooling bill. Hung replacements in Union Park typically fall between $450 and $1,500 per opening, and we quote manufacturer lines side by side on paper so the comparison is literal, not verbal.

Trusted Brands We Service in Union Park
Union Park homeowners deserve a straight answer about what is going into their walls, which is why we quote three manufacturer lines side by side before a dollar is committed. TruePane is an authorized installer for more than a dozen manufacturers, and on Union Park jobs we find ourselves quoting ES Windows, ECO Window Systems, and CGI most often, depending on the opening and the wind-zone requirements. ES Windows gives us the clean architectural look for custom casement and picture work. ECO Window Systems holds its own on thermal performance for the tighter budget. CGI is the go-to when the homeowner wants a full impact package across the entire home and wants the insurance credit to match. We hold no brand loyalty beyond what serves the job, and we carry local stock for Union Park service calls so a warranty follow-up is a days-long thing, not a weeks-long one.
Common Window Installation Problems We See in Union Park Homes
When you replace windows in Union Park long enough, the same failure modes keep showing up. These four get the most calls.
- Fogged insulated glass units in original aluminum frames. The argon has leaked out, the seal has failed, and the U-factor is degraded to the point that the window now insulates about as well as a single pane. In Union Park’s daily hot-cold swing, this failure accelerates fast, and an opening that looks fine from across the street is actively costing money.
- Jalousie windows on Florida rooms and screened additions that cannot be weatherstripped. These louvered glass-slat units were everywhere in 1970s Union Park construction, and every one of them leaks rainwater around each slat and fails current wind and energy code provisions. There is no repair, no retrofit, no weatherstrip kit that fixes a jalousie. Full-frame replacement is the only permitted path.
- Pitted and oxidized aluminum frames on non-coastal homes. Union Park is far enough inland that homeowners do not expect the level of surface degradation their frames actually show. The daily UV load and the seasonal thermal cycling break down the original aluminum finish faster than salt air would in a gentler climate.
- Rotted wood door jambs and sill pans on southwest-facing elevations. The original builder flashing was often absent, and Union Park’s afternoon storm pattern means wind-driven rain finds every gap. Once water gets into a wood jamb on a patio door or a garden window, the rot advances within a few wet seasons.
Pricing for Window Installation in Union Park, FL
Price is the thing most Union Park homeowners want to know before they will even book an estimate, and we respect that. A straightforward single-hung replacement on the SR-50 side of the neighborhood likely lands between $450 and $650. A full-frame casement replacement in an impact-rated assembly runs $800 to $1,400. Custom picture windows, architect-specified millwork, and jamb extensions on older block homes can push a single opening past $1,900. The variables are real: glass package, design pressure rating, whether the opening needs new framing or flashing, and whether the homeowner’s architect wants a level of finish beyond a standard interior return. What does not change is the way we price. The quote is fixed in writing before anything is ordered, and there are no change orders hiding in the fine print. Call (954) 280-4413 for a free line-item estimate on your Union Park windows.

FAQs – Window Installation in Union Park
A jalousie window has no sealed frame, no thermal barrier, and no weatherstrip that survives a Central Florida storm. Each glass slat pivots independently, which means every louver edge is a leak point, and there is no practical way to seal the assembly to meet current Florida Building Code wind and energy provisions. A repair or a retrofit cannot bring a jalousie into compliance, and an inspector will not pass it. Full-frame replacement is the only legal path. Call (954) 280-4413 and we will walk you through the options for replacing a jalousie in Union Park.
Wind-mitigation credits in Orange County are tied directly to the design pressure rating of the window or door assembly and whether the installation documentation proves it meets current code. A 1980s original aluminum slider will not earn the credit because it was never tested to the pressure rating your carrier now wants. A properly documented, impact-rated or high-DP replacement will. We register both manufacturer warranty layers in writing before the truck leaves your driveway, and your permit inspection provides the paper trail the insurance carrier asks for. Call (954) 280-4413 for a free estimate that includes the wind-rating documentation.
Custom casement and picture windows specified by an architect for a Union Park home typically run six to ten weeks from order to install, depending on the manufacturer and glass package. The lead time is driven by the factory schedule, not by our labor, and we are candid about that before the contract is signed. The price gets fixed in writing before the order goes in, so a six-week factory delay does not become a surprise line item on the final bill. Call (954) 280-4413 to discuss your architect’s drawings and we will give you a realistic timeline.
Union Park’s inland climate delivers year-round UV that breaks down the original anodized and painted finishes on 1970s-to-1990s aluminum frames faster than coastal salt air alone would suggest. The daily cycle of heat, rain, and rapid drying stresses the old finish until it pits and oxidizes, especially on south and west elevations. Once the surface is compromised, the frame starts losing structural integrity at the corners and the glazing seal follows. Replacement is the durable fix. Call (954) 280-4413 for a free assessment of your Union Park windows.
No. The original aluminum slider frames in Union Park’s earliest tract homes were never tested to current design pressure ratings and cannot be retrofitted to pass. Replacing only the glass leaves the same non-compliant frame in place, and the Orange County permit process will not accept it. Full-frame replacement with a properly rated assembly is the only path to code compliance and insurance credits. Call (954) 280-4413 and we’ll show you what a compliant replacement costs for your specific openings.
