AfterTherma-Tru Custom & Geometric Windows in Miami Shores: What to Know First
We’re an independent Therma-Tru service provider in Miami Shores, and we install and repair custom and geometric Therma-Tru windows, including arched, radius, oval, and oversized units. Most custom-shape repairs run between $300 and $1,800 depending on glass type and frame complexity, and we quote the job before we order a single part so you know exactly where you stand. If you own a Therma-Tru product with a curved or unusual opening, call (727) 483-7883 and we’ll walk you through what’s actually wrong over the phone first.
How Therma-Tru Products Fail - and How We Fix Them
- Sash warping on radius frames. Therma-Tru’s fiberglass and composite frames hold their shape better than wood, but we still see bowed sashes on wide arch-top units in Miami Shores, especially on west-facing walls. The heat load softens the frame material just enough to break the weather seal. We check the frame square first, then realign or replace the sash, never just caulk over it.
- Glass seal failure on geometric picture windows. Odd-shaped Therma-Tru units, trapezoids and half-rounds especially, tend to have insulated glass units that lose their inert gas fill faster than standard rectangles. The edge seal on a steep angle works harder in the humidity we get off Biscayne Bay. The fix is a custom IG unit fabricated to the exact radius, not a field repair that fogs again in two years.
- Hardware fatigue on casement and awning shapes. Therma-Tru’s crank-out casements and awnings made in geometric sizes put more stress on the hinge sets than a standard double-hung ever does. We’ve replaced more stripped operator arms on Miami Shores Therma-Tru units than any other single part. We stock common replacements and order OEM for anything with a warranty still live.
- Flashing failures at the apex of arched openings. The top of an arch is where water gets in if the original install cut corners on flashing. We see it on Therma-Tru units installed during the big South Florida build-out years. Our fix is a full remove-and-reframe of the opening with proper head flashing, not surface sealant.
- Frame stress cracks on oversized openings. Therma-Tru makes a strong product, but put a 6-foot-tall geometric unit in a wall that settles, and fiberglass will eventually crack at the corner radius. We’ve repaired clean hairline cracks on Therma-Tru FrameSaver and pulse-line units with structural epoxy that keeps the frame serviceable, and we’ll tell you honestly when a full sash replacement is the smarter money.
Our Therma-Tru Custom & Geometric Windows Process
- 1
Call us. A live person answers, day or night. We ask about the window shape, the symptom, and the age of the unit to figure out if this is a common Therma-Tru pattern or something unusual.
- 2
We inspect the opening. We measure the frame, check for square, and look for the root cause, not just the visible damage. On geometric units, that means checking the radius at multiple points.
- 3
We decide OEM versus aftermarket with you. If your Therma-Tru warranty is active, we order OEM parts to keep it intact. If it’s long expired, we show you quality aftermarket options that cost less and hold up just as well in this climate.
- 4
We do the repair or replacement. Custom glass units get fabricated to exact radius and dimension. Frames get squared, sealed, and flashed correctly. No shortcuts on the apex flashing, ever.
- 5
We test the seal and operation. We check for air movement around every edge, run the hardware through full cycles, and confirm the frame is draining properly.

What Therma-Tru Custom & Geometric Windows Costs in Miami Shores
Here’s what we typically see on Therma-Tru custom and geometric work in Miami Shores:
- Glass replacement on an arched or radius Therma-Tru window: $350 - $900 per unit, depending on radius and glass type (low-E, impact-rated, or standard insulated).
- Full geometric window replacement (custom shape, standard glass): $1,200 - $2,800 per opening, installed.
- Impact-rated geometric window replacement: $1,800 - $4,200 per opening, installed. Miami Shores code requires impact-rated or shuttered openings on new work.
- Hardware repair (hinges, operators, locks) on Therma-Tru casement or awning shapes: $180 - $450 per window.
- Full-frame replacement for an oversized arch-top unit: $3,000 - $6,500 depending on size and structural work needed.
What moves the price: the radius tightness, whether you need impact glass, whether the frame itself is compromised, and how much flashing work the opening needs. We give you a written, line-item quote before we order anything. Call (727) 483-7883 to schedule a free estimate.

We measure, order, and handle the install from start to finish, and we board up the opening securely if the old glass is compromised while the new unit is in production.
