Therma-Tru Custom & Geometric Windows in Coral Gables: What to Know First

We install and service Therma-Tru custom and geometric windows throughout Coral Gables, including arched, radius, oval, and oversized openings. Most custom-shape Therma-Tru projects run from two to six weeks from template to install, and we provide upfront line-item pricing before we cut the first piece of glass. If you own a Therma-Tru window in Coral Gables and it’s fogged, warped, or leaking around a curved frame, call (904) 478-8983. This page is for Coral Gables homeowners who want straight answers about their Therma-Tru windows – what fails, what it costs, and what we do differently.

How Therma-Tru Products Fail – and How We Fix Them

Therma-Tru builds a solid product, but Coral Gables heat, humidity, and hurricane cycles expose weak points in their custom geometric lines faster than in their standard rectangles. Here’s what we see most often on service calls between the Biltmore and Gables by the Sea:

  • Fogged insulating glass in Therma-Tru’s geometric shapes. Arched and radius windows put uneven stress on the seal where curved glass meets the frame. In Coral Gables, where afternoon temperatures climb past 90 and humidity sits above 70 percent, that seal flexes and fails faster than a flat window. We see fogging in Therma-Tru radius units as early as year seven or eight. The fix is a new custom-cut insulated glass unit matched to the original curve – and we template every arch by hand before ordering, because a quarter-inch miss means the sash will never seat right.
  • Frame rot at the base of decorative half-rounds and eyebrow windows. Weathered-in Therma-Tru wood-composite shapes collect water at the sill where the curve meets flat jamb. If the flashing was even slightly off, or the weep holes got painted over, water sits there. In a climate that averages 60 inches of rain a year, that’s a slow decay problem. We remove the rotted section, rebuild it with rot-resistant material, and re-seal with a marine-grade caulk that holds up in salt air.
  • Sash misalignment in oversized geometric openings. A 6-foot radius or oversized octagon carries more glass weight than the hinge hardware was designed to handle if the rough opening settled even a hair. Coral Gables sits on oolitic limestone, and houses shift. The symptom is a window that won’t close fully on the curved side. We re-shim, re-square, and replace worn hinges – sometimes with upgraded stainless hardware that stands up better to coastal air than factory zinc.
  • Clouded glass in Therma-Tru’s obscure and decorative geometric lines. If you have a beveled, leaded, or textured geometric window, the custom glass is often the first thing to go. Therma-Tru doesn’t keep every decorative pattern in production forever, so when a window fails, we work with specialty glass suppliers who can reproduce the texture and bevel. It’s one of the few times you’ll hear us recommend aftermarket over OEM, because matching the original look matters more than matching the part number.
  • Leaking at the seam where a geometric transom meets the main window below. In Coral Gables, driving rain hits these seams at angles flat windows never experience. The original gasket compresses, dries out, and shrinks. We replace it with a compression gasket cut to the exact radius and verify the drainage channels are clear before we finish the job. Skipping that second step is how leaks come back a month later.

Our Therma-Tru Custom & Geometric Windows Process

Every Therma-Tru job in Coral Gables follows the same path, whether it’s a small repair or a full replacement of an arched window package:

  1. 1
    Call and talk to a real person. When you call (904) 478-8983, someone picks up. We ask where you live, what shape the window is, and what’s going wrong. If you’re in our home county, there’s no trip charge.
  2. 2
    On-site inspection and measurement. We come out, measure everything twice, and check the rough opening, the flashing, and the condition of the frame. For custom shapes, we template the curve on site. That prevents expensive ordering errors.
  3. 3
    Upfront pricing. You get a written, line-item estimate before any work starts. Not a ballpark. Not a hand-wave. The number we quote is the number you’ll pay.
  4. 4
    Parts decision. We tell you when OEM Therma-Tru parts are worth the premium and when a quality aftermarket alternative will perform better for less. You decide. We stand behind either choice.
  5. 5
    Install or repair. Background-checked, uniformed technicians do the work. We protect your floors, remove the old unit cleanly, and set the new one square and level.
  6. 6
    Test and walk-through. We run water tests on the exterior, operate the window several times, and walk you through what we did. If it’s not done right, the Done Right Promise means we come back and make it right. Every job, every time.

What Therma-Tru Custom & Geometric Windows Costs in Coral Gables

Here’s what we tell Coral Gables homeowners to expect, based on years of Therma-Tru work in Gables Estates, Cocoplum, Snapper Creek, and the neighborhoods around Miracle Mile:

Scope Typical Coral Gables Range
Reseal a leaking geometric window $180 – $400
Replace fogged glass in one arched or radius unit $450 – $950
Rebuild rotted frame section $300 – $800
Replace a standard-size Therma-Tru geometric window $1,400 – $3,200 installed
Replace an oversized or custom radius window $3,500 – $7,500 installed

Glass size, curve complexity, frame material, and whether the opening needs structural work all move the number. You’ll also see a permanent $40 credit on any repair over $200, and seniors and veterans get 10 percent off every job. Call (904) 478-8983 for a free written estimate – no pressure, no vague ranges.

Why Coral Gables Homeowners Call Winslow Windows & Doors for Therma-Tru Work

We’ve been at this since 2011, and Ed Winslow – the owner whose name is on the truck – grew up in Coconut Grove and studied building construction technology at Miami Dade College. He spent more than two decades replacing windows and doors across Coral Gables before most national chains had a local crew worth calling. We know what salt air does to hardware, what limestone soil does to rough openings, and what hurricane code means for a 6-foot radius window facing the bay. If we’re working on your Therma-Tru and recommend a replacement from PGT, CGI, CWS, or ES Windows instead, it’s because the numbers support it – not because we get a better margin. And every job carries the Done Right Promise. Ed’s name is on the door – and on every job we do.

What Neighbors Say About Winslow Windows & Doors

★★★★★

"We sat out a hurricane behind the windows Ed put in. The gusts threw a neighbour's trampoline down the street and the loudest thing in our house was the kettle. I rang him after to say thank you and he answered his own phone, same as always."

TThaddeus Okonkwo
★★★★★

"Ed measured every opening himself and walked me through the product approval paperwork before I signed anything. When the inspector came he found the notice of acceptance taped inside a window like it should be and passed us first visit."

RRosalind Beaumont
★★★★★

"A tile roof repair and new windows from the same company meant one crew, one permit runner, and nobody blaming the other trade. Ed checked the roof work himself before the tarp came off."
