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

TruePane Windows & Doors installs, services, and replaces Therma-Tru custom and geometric windows across Coral Gables, FL. Most custom shape jobs (arches, circles, ovals, triangles, oversized openings) take two to four weeks from template to install, depending on the glass package and frame reinforcement required. Pricing runs honest and itemized: we walk the opening, measure twice, and hand you a written line-item quote before any work starts.

Call (954) 507-3613

This page is for Coral Gables homeowners who own Therma-Tru windows and are dealing with a failing custom shape: a fogged arch over the front door, a leaking picture window, a geometric unit that binds in summer humidity. If that sounds like your house, call (954) 507-3613 and a live person will answer.

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

Therma-Tru built their name on entry doors, and their matching sidelight and transom window lines carry that same engineering. But the custom and geometric units see failures that stock rectangular windows never do. Here is what we find in Coral Gables homes:

• Therma-Tru Classic-Craft transoms and radius units lose their seal at the apex. The curved glass sits under constant thermal stress from Florida sun beating on the top arc. The polyisobutylene seal eventually separates, moisture enters, and the homeowner sees fog at the top of the arch. The fix is not a quick defog. We template the opening, source a matching dual-pane insulated glass unit with the same Low-E spec, and reset the sash. Dale Kessler has pulled enough of these to know exactly what happens.
• Sidelight frames around Therma-Tru entry systems rot from the bottom up. In Coral Gables, the humidity and summer rain find the wood-composite joint at the sill. Therma-Tru reinforced their frame construction over the years, but older installations from the 1990s and early 2000s were not sealed the way current ones are. We cut out the rotted section, rebuild with a composite replacement, then flash and caulk to keep water from ever sitting on that joint again.
• Therma-Tru Smooth-Star window openings warp. These fiberglass units are tough, but hurricane-panel retrofits that overlap the frames can trap heat and cause bowing over time. The glass does not fail first. The frame does. We true the opening, shim correctly, and reset the unit so it closes square instead of scraping the gasket.
• Oval and eyebrow windows in Therma-Tru telescoping systems stick in July. The geometry of a curved sash in a Florida climate means the vinyl or fiberglass expands more than the glass. Homeowners in the Biltmore and Hammock Oaks areas call us every summer about this. We plane the sash rails, reset the balance, and lubricate with a dry silicone before testing the full open-close cycle.
• Therma-Tru insulated glass developed a hazy film that won’t wipe off. That haze is between the panes. It’s a failed seal, not a dirty window. Coral Gables salt air accelerates it, especially on homes near the water. We pull the IGU, order a replacement from our glass suppliers who stock Therma-Tru-compatible dimensions, and reseal with fresh glazing tape. You get a clear view, not a smear that returns in six months.

Our Therma-Tru Custom & Geometric Windows Process

Here is how a Therma-Tru custom or geometric job goes at TruePane Windows & Doors. It’s the same process every time because that is the only way a forty-two-year reputation holds:

1. 1
   Walk and measure. A background-checked, uniformed technician comes to your Coral Gables home, inspects the opening, and measures it twice. For geometric shapes we template the actual curve rather than trusting the old frame’s dimensions.
2. 2
   Diagnose the real failure. Is it the glass, the seal, the frame, or the install? We pull the stops and look at what is happening inside the wall cavity before recommending anything.
3. 3
   Parts decision. For glass and seals, we always recommend OEM-spec Therma-Tru replacement units when available. For frames and hardware where OEM is discontinued or backordered, we use a proven aftermarket equivalent and tell you exactly what you are getting before we order it.
4. 4
   Quote in writing. No verbal estimate, no “we’ll figure it out later.” Line items for every part, every labor hour, and the warranty registration. If it is not in writing, it is not a guarantee, it is just a conversation.
5. 5
   Set and seal. We install the unit, flash the perimeter, and check plumb, level, and square. Then we run a water test on the exterior seam before we clean the glass and hand you the job.
6. 6
   Paperwork. Both manufacturer warranty layers get registered in writing before the truck leaves your driveway. We note the durations, we note who to call, and we leave you a copy signed by the technician.

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

Therma-Tru custom and geometric window pricing in Coral Gables runs wide because the shape drives the cost. Here is what we see on real jobs:

What moves the price in Coral Gables is mostly the sculpted glass and the engineering behind it. A true arch with a curved IGU costs more than a square unit with an arched frame. An impact-rated geometric unit with Miami-Dade product approval costs more than a non-impact one. If you want a square deal, call (954) 507-3613 and we will come measure and put your exact price in writing. Estimates are free.
