Fast, Reliable Window Replacement Across Union Park
Window replacement in Union Park almost always comes down to one question: will the new windows pass Orange County’s wind-mitigation inspection and cut your insurance premium, or will they just look nicer for a year? Most homes here were built between 1972 and 1995 with single-pane aluminum frames, and those units cannot meet today’s Florida Building Code for wind load or energy performance. TruePane Windows & Doors replaces them with properly rated, permitted, compliant windows – and we register both warranty layers in writing before our truck leaves your driveway. Call (954) 280-4413 to talk through your house, your windows, and what a compliant quote actually includes.
Why TruePane Windows & Doors Is Union Park’s Preferred Window Replacement Company
We have been pulling permits through Orange County’s building department long enough to know what their inspectors look for on a Union Park tract home. The homes off SR-50 and over near Hiawassee Road have a specific set of problems: oxidized aluminum frames, failed seals on original single-pane units, and jalousie windows that will never pass a wind-mitigation inspection no matter how many slats you replace. Our crews know these houses because we have worked on hundreds of them. We measure every opening twice, quote manufacturer lines side by side on paper, and file the permit before the first window comes out.
TruePane is led by Dale Kessler, a second-generation glazier who founded the company in 2008 on a simple rule: if the pane is not true, the job is not done. That rule governs every install in Union Park. Our technicians are background-checked and uniformed. They work in your home the way they would work in their own mother’s. And when the job is finished, you get our Done Right Promise in writing. If something is not right, we make it right. No paperwork fights, no arguing.
We serve Union Park directly. Dispatch and scheduling are coordinated from our South Florida metro office, but the crews working on your windows are local, trained in Orange County’s residential window replacement scope, and familiar with the specific failure modes of 1970s through 1990s Central Florida tract housing.
Our Window Replacement Services in Union Park
Full Frame Replacement
Most Union Park homes need full frame replacement, not an insert. The original aluminum frames on homes built in the 1970s and 1980s are pitted, oxidized, and were never designed to hold a modern impact-rated or energy-efficient window. A full frame replacement removes everything down to the rough opening, lets us flash and seal that opening to current Orange County inspection standards, and gives you a window that actually carries a DP rating high enough to satisfy a wind-mitigation report. For a typical 1,800-square-foot concrete-block home in Union Park, full frame replacement on 10 to 14 windows runs roughly $9,500 to $21,000 depending on the manufacturer line and glass package.

Insert Window Replacement
Inserts make sense in Union Park only when the existing frame is still square, sound, and free of corrosion. That is rare on original aluminum frames from the 1980s, but it does happen on some of the early-1990s builds closer to Goldenrod where frames were better protected. An insert replacement in Union Park typically runs $600 to $1,100 per opening. We will tell you honestly whether an insert will pass inspection or whether it is a short-term fix that leaves an out-of-true frame in place.

Storm Window Replacement
For Union Park homeowners who want a second layer of protection without replacing every window at once, storm windows can buy time and cut energy loss. But here is the thing: storm windows do not change the underlying window’s wind rating or code compliance. If your goal is the wind-mitigation insurance credit, storm windows alone will not get you there. We install them where they make sense – Florida rooms, screened additions, detached structures – and we are straight with you about what they will and will not do for your insurance report. Expect to pay $350 to $700 per storm window in Union Park, installed and sealed.

Energy-Efficient Upgrade
Union Park’s inland Central Florida climate punishes windows year-round. Intense UV radiation degrades vinyl glazing seals and oxidizes aluminum frames faster than coastal salt air alone. The daily wet-season cycle – torrential afternoon thunderstorms followed by rapid drying – causes wood jambs and sill pans to swell, rot, and lose their weather seal within a few years of any moisture intrusion. Replacing original single-pane units with Energy Star-rated double-pane Low-E windows changes the inside of a Union Park home in July. A typical energy-efficient window replacement package for a 1970s tract home runs $8,000 to $18,000 for a full house, and most homeowners see the difference on their first electric bill after the first full cooling season.

Trusted Brands We Service in Union Park
We are an authorized installer for more than a dozen manufacturer lines, and we quote them side by side on paper so you can see exactly what you are buying. For Union Park’s wind-zone requirements and UV exposure, we frequently recommend Andersen for proven long-term performance, PGT for impact-rated glazing that meets Orange County’s inland wind-speed requirements, and Simonton for double-hung replacements on 1980s tract homes where the original frame openings are a standard size. We keep common components and hardware in local stock for Union Park jobs, which means we are not waiting on a regional warehouse to finish your install.
Common Window Replacement Problems We See in Union Park Homes
- Failed seals on original single-pane aluminum windows. Within a decade of Florida UV and wet-season humidity, the glazing seals on original aluminum units fail and the frames oxidize and pit. Homeowners end up with fogged, impossible-to-clean glass that does not meet current energy code.
- Jalousie windows that leak at every louver pivot. In Union Park’s oldest blocks, jalousie windows still appear regularly on Florida rooms and secondary bedrooms. They cannot be weatherstripped or flashed for wind-driven rain, so during the daily afternoon thunderstorms they leak, and they fail every Orange County wind-mitigation inspection.
- Rotting hollow-core exterior doors and aluminum patio door sills. The daily wet-dry cycle in Central Florida causes wood jambs and sill pans to swell and rot. By the time a homeowner sees the damage, the rough opening usually needs a fusion-welded frame to pass a wind-load test.
- Windows installed without a permit by a previous owner or handyman. We see this often in Union Park. A homeowner paid cash for windows a decade ago, no permit was pulled, and now the wind-mitigation inspection flags them. The only fix is a compliant reinstallation with a proper Orange County permit.
Pricing for Window Replacement in Union Park, FL
Here are real numbers for Union Park, not vague ranges you would see on a national website. A single full-frame replacement window on a typical concrete-block tract home runs $800 to $1,500 installed, depending on the manufacturer, glass package, and whether you choose impact-rated glazing. A full house of 10 to 14 windows runs $9,500 to $21,000. A simple insert replacement runs $600 to $1,100 per opening. Storm windows run $350 to $700 each. What moves the price: the DP rating required for your specific opening, whether we are replacing a jalousie with a structural frame (yes, that costs more than a standard opening), the manufacturer line you choose, and whether the existing rough opening needs any remediation before we set the new frame. Call (954) 280-4413 for a free estimate. We give you a written line-item quote with both warranty layers registered in writing before the truck leaves your driveway.

FAQs - Window Replacement in Union Park
Orange County enforces the Florida Building Code’s inland wind-zone requirements, which for most Union Park homes means the window assembly must carry a DP rating of at least DP 35 to DP 45, depending on the specific opening location, the home’s exposure category, and the roof height and geometry. A licensed contractor submits a product approval sheet or NOA (Notice of Acceptance) with the permit application that documents the exact DP rating for each window. A cheap quote that omits product approvals will fail the permit review before it ever gets scheduled for inspection. Call (954) 280-4413 and we will tell you what your specific home needs based on its address and construction year.
No. The wind-mitigation credit is based on the entire window assembly, including the frame’s structural rating, not just the glass. Original 1980s aluminum frames in Union Park were not engineered or tested to meet current Florida Building Code wind-load requirements, and they cannot be retrofitted to pass. Replacing only the glass leaves the frame non-compliant, which means the orange county wind-mitigation inspector will flag it and your insurance discount will not apply. You need a full frame replacement with a rated product and a passed inspection. Call (954) 280-4413 for an exact quote on your specific openings.
Jalousie windows are louvered glass slats that pivot open on metal levers. They create hundreds of linear feet of unsealed joint around every slat edge. No weatherstripping or sealant can close those gaps to a wind or water standard, and the frames themselves were never tested or rated for wind-load resistance. Replacing the slats gives you new glass in a frame that still fails every current wind and energy code provision. In Union Park’s oldest blocks, where these units still appear on Florida rooms and secondary bedrooms, the only legal and practical path is a full-frame replacement with a properly rated window. Call (954) 280-4413 and we will assess your jalousie openings and quote the replacement.
A compliant Union Park window replacement permit drawing should include the specific window product approvals (NOAs), the DP rating for each opening, the anchoring schedule and fastener type, the flashing and sealing details at the rough opening, and the scope narrative that matches Orange County’s residential window replacement permit category. Low-bid quotes often omit the product approvals, the anchoring schedule, or the flashing detail drawing, which means the permit gets rejected or the inspection fails on the first visit. TruePane includes all of this in every quote, because a permit without the right documentation is just a fee with extra steps. Call (954) 280-4413 for a compliant, line-item quote.
Yes. Original single-pane aluminum windows are essentially thermal holes in a Union Park home. They transmit heat directly into the house during Central Florida’s 90-degree-plus summers and allow conditioned air to escape year-round. Replacing them with Energy Star-rated double-pane Low-E units reduces the home’s cooling load measurably, which lowers the energy audit score that Orange County uses for new permits and resale disclosures. The exact reduction depends on the window package you choose and the number of openings, but every Union Park homeowner we have worked with sees a meaningful drop after the first full cooling season. Call (954) 280-4413 and we will quote the specific Energy Star package for your home.
