PGT Custom & Geometric Windows in Coral Gables: What to Know First
PGT custom and geometric windows in Coral Gables typically take 2-4 weeks from measurement to installation, and most jobs run between $900 and $2,800 per opening depending on glass package, frame finish, and whether the shape is arched, radius, or a true polygon. We’re an independent PGT service provider, not a dealer showroom, which means we measure, order, and install exactly what your opening needs without a markup on top of a markup. If you own a PGT home in Coral Gables and the window is a circle, an arch, a trapezoid, or something the original builder swore was “standard” but isn’t, this page is for you. Call (904) 478-8983 and Ed Winslow or one of our techs will actually pick up.
How PGT Products Fail - and How We Fix Them
- WinGuard Vinyl radius units pulling away at the weld corners. Coral Gables heat cycles expand and contract vinyl more aggressively than most climates. On PGT WinGuard custom arches we regularly see hairline separations at the radius welds, especially on south-facing elevations. The fix is either a full sash replacement through PGT’s custom shop or, when the frame is sound, a weld reinforcement with our vinyl bonding process. We’ll tell you which one your window actually needs.
- Aluminum custom shapes losing their powder coat within 5-7 years. PGT’s aluminum custom lines, particularly the older 7700 series shaped units, hold up structurally but the original powder coat doesn’t love Coral Gables’ salt air and afternoon sun. We see pitting and chalking around the mullion joints on geometric windows on Granada and Biltmore-area homes. We strip, prep, and recoats to match PGT’s current finish specs, or we order a new sash if the corrosion has reached the frame.
- Arched transom windows with failed PolySeal gaskets. PGT’s custom arched transoms use a PolySeal gasket that dries out faster in Coral Gables’ humidity swings than in inland Florida. The symptom looks like a mystery leak or a fogged unit, but the real cause is often a gasket that’s turned brittle. We replace the gasket with PGT-spec material before recommending a glass replacement, which saves the homeowner a thousand dollars on a window that doesn’t actually need new glass.
- Geometric fixed units with unexplained glass stress cracks. Trapezoid and diamond picture windows from PGT’s 7700 and WinGuard lines occasionally develop stress cracks that don’t trace back to impact. In Coral Gables we see this on homes with mature tree canopies where the frame shifts slightly as roots move. We diagnose by checking the reveal around the glass, and if the opening is moving, we’ll prescribe a frame adjustment or re-shim rather than just swapping the glass and waiting for the next crack.
- Oversized custom sliders with bearing wear. PGT’s custom sliding glass units in Coral Gables, especially wide-span openings, wear out the roller bearings faster than spec sheets suggest because of the fine coral dust in the air here. What sounds like a structural problem is usually a $40 part. We carry PGT-spec rollers and keep them in the truck.
Our PGT Custom & Geometric Windows Process
- 1
Measure twice, order once. We come to your Coral Gables home and measure every leg of the opening, every radius, every diagonal. Custom shapes have no tolerance for a rounding error.
- 2
Parts decision. We confirm whether the unit is under PGT warranty (which affects replacement parts sourcing) and whether OEM or a quality aftermarket component is the right call. We show you the difference before we order anything.
- 3
Order and prep. If it’s a new custom unit, we order through our PGT supply chain. If it’s a rebuild, we strip the old hardware, clean the frame channels, and prep the opening.
- 4
Install or repair. Our background-checked, uniformed techs set the new unit, anchor it to Coral Gables code, seal with Florida-rated flashing, and pull the reveal so the window operates true.
- 5
Test and walk. We cycle the window, check locking points, run water on the exterior, and show you the finished product before we leave.
- 6
The guarantee. Every job is covered by the Done Right Promise. If it’s not right, Ed Winslow makes it right.

Why Coral Gables Homeowners Call Winslow Windows & Doors for PGT Work
Ed Winslow grew up in Coconut Grove, a few blocks from the Biltmore, and he’s been working Coral Gables homes for more than two decades. He studied building construction technology at Miami Dade College and has spent his entire working life dealing with South Florida sun, salt air, and hurricane season. That means when we look at a PGT custom window in Coral Gables, we know what this climate does to vinyl welds, powder coat, and gaskets. We carry PGT-spec parts, we know which series your window actually is, and we won’t upsell a glass replacement when a gasket swap fixes the leak. If the job isn’t done right, the Done Right Promise means we come back. We also service CGI, CWS, ES Windows, and ECO Window Systems, so if your home has a mixed-brand window package (very common in Coral Gables), you’re still calling one number. My name is on the truck. That means I’m the one accountable if anything’s off - and it never is.
FAQs
Yes. We template the existing opening, confirm the PGT series from the corner etch or spacer bar, and order an exact match from our PGT supply chain. Coral Gables homes specifically have a lot of arched and radius transoms from 1990s-era builds, and we match those every week.
Call (904) 478-8983 if you want someone to look at the opening and tell you what’s actually possible. Estimates are free.
Not if it’s done correctly. We’re an independent PGT service provider, which means we’re not authorized by PGT, but we use PGT-spec parts where the warranty is active, and we document the work. On older units where the warranty has long expired, we’ll often recommend a quality aftermarket part that outperforms the original at half the cost.
Call (904) 478-8983 and we’ll look up your window’s production date and tell you exactly where you stand.
We repair wherever repair makes sense, which is most of the time. We reglaze, replace gaskets, swap hardware, re-weld vinyl corners, and re-powder-coat aluminum frames. Replacement only comes up when the glass is failed, the frame is structurally compromised, or the cost to rebuild exceeds 70% of the price of new. Call (904) 478-8983 for a straight recommendation, not a sales pitch.
Most custom PGT units take 2 to 4 weeks from measurement to delivery, and installation adds one day. Templated shapes (arches, full-rounds, true polygons) run on the longer end. We’ll give you a firm timeline before you pay anything.
Call (904) 478-8983 to get the clock started, and remember there’s no trip charge for Coral Gables homes when you’re in our home county.
Yes, when the job calls for it. Coral Gables requires permits when the opening size changes or the structural frame is touched. We handle the permit paperwork, pass the inspections, and your job isn’t finished until the city signs off. If it’s a like-for-like window swap, the permit often isn’t required, and we’ll be honest about that instead of charging you for paperwork you don’t need.
