Therma-Tru Custom & Geometric Windows in Hialeah: What to Know First
We install and service Therma-Tru custom and geometric windows throughout Hialeah, including arched transoms, radius tops, unusual angles, and oversized openings. Most custom Therma-Tru jobs take two to four weeks from measurement to install, depending on the glass package and frame profile, and pricing reflects the geometry: custom shapes run higher than stock rectangles because the tooling, labor, and glass cutting are one-off. Call (386) 977-5410 for a free estimate and a written line-item quote.
This page is for the Hialeah homeowner with a Therma-Tru window that does not fit a standard opening: the half-round over the entry door, the trapezoid in the stairwell, the octagon in the den. If you have been told by another contractor that your window shape is “special order” and the quote reflects confusion more than work, you are in the right place.
How Therma-Tru Products Fail - and How We Fix Them
- Therma-Tru casement and awning units in Hialeah develop sag at the hinge side on geometric shapes. A trapezoid or parallelogram window carries weight differently than a rectangle, and over years of Florida humidity cycling, the corner welds at the bottom hinge start to pull. You will see the sash drop a quarter inch and the crank get stiff. We reset the sash, repair or replace the hinge hardware, and re-square the opening so the load sits true. If the weld has actually cracked, we replace the sash frame, not just the hardware.
- Radius and arched Therma-Tru windows lose their seal where the curved glass meets the sash frame. The curved glass unit is bent to a specific radius at the factory, and the flexible sealant around that curve hardens faster in Hialeah’s heat than Therma-Tru’s literature suggests. You will see condensation inside the glass on the arc, near the pointed tip of an eyebrow window. We de-glaze the unit, clean the channel, install a new insulated glass unit matched to that radius, and re-seal it with a sealant rated for our humidity. This is one of the most-frequent Therma-Tru repairs we do west of the Palmetto.
- Therma-Tru deadbolts and lock hardware on French-style geometric units drift out of alignment. The multi-point locks Therma-Tru uses on their hinged geometric units depend on the slab hanging square. After a few seasons of Miami-Dade heat and rain, the strike plates move a sixteenth of an inch. The door still operates, but the lock throw gets partial and then fails. We re-hang the panel, adjust the strikes, and re-align the multipoint gearbox. No new hardware needed in most cases.
- Custom Therma-Tru trim and brickmold delaminate on the sun-side of Hialeah homes. The composite brickmold Therma-Tru specs is durable, but in full south and west exposure the outer skin can separate from the core after ten to twelve years. Homeowners near Amelia Earhart Park and Palm Springs North see this more often because the lots are open and the sun is unforgiving. We replace the brickmold with the correct Therma-Tru profile and finish it to match the adjacent window trim.
- Oversized geometric Therma-Tru units bow their headers if the original rough opening was never reinforced. A large half-round over a double door carries real weight, and if the original builder skipped the header splices or used undersized lumber, the opening settles. The window pins and the frame cracks at the top arc. We pull the unit, correct the header with proper LVL or steel reinforcement, and reinstall the Therma-Tru unit on a square opening. If the opening is not square, nothing else matters, and we will not set a $2,000 window into a bad hole and call it done.
Our Therma-Tru Custom & Geometric Windows Process
- 1
Call and schedule. A live person answers at (386) 977-5410. We book a time that works for you and show up when we say.
- 2
Measure and document. Our tech opens the window or door, checks the rough opening for square, photographs the label on the frame that identifies the Therma-Tru series, and records the exact geometry, jamb depth, and glass package.
- 3
Parts decision. We determine whether an OEM Therma-Tru part is required to preserve your warranty or whether a quality aftermarket part will serve just as well. For visible components like sash frames and glass we stay OEM. For internal hardware like rollers, balance springs, and weatherstripping, we use aftermarket parts from suppliers we have run for years.
- 4
Written quote. We put a fixed price on paper with no allowances and no change orders unless you change the scope.
- 5
Do the work. We install, replace, or repair the window or door, register every warranty layer in writing, and test the operation at least ten full cycles before we call it done.
- 6
The Done Right Promise. If anything is not right, we come back and make it right. No arguing, no fine print.
What Therma-Tru Custom & Geometric Windows Cost in Hialeah
Here is what we see in Hialeah homes, based on jobs we have completed across the city:
- Arched or half-round transom replacement (glass only): $420 to $780
- Full arched or radius window replacement (standard glass package): $1,100 to $2,200
- Geometric trapezoid or octagon replacement (up to 36 inches): $900 to $1,800
- Oversized geometric window (48 inches or larger, impact glass): $2,200 to $4,500
- Custom Therma-Tru hinged door with curved top panel: $2,800 to $5,600
What moves the price: impact-rated glass adds 30 to 45 percent over standard insulated glass, low-E coatings run $150 to $400 per unit depending on size, and any opening that needs structural correction before we set the window will add material and labor. There is a permanent 5 percent discount for seniors and veterans. We will quote it in writing. Call (386) 977-5410.
Why Hialeah Homeowners Call TruePane Windows & Doors for Therma-Tru Work
We have been fixing and installing windows in Hialeah since 2008 as a company with a second-generation glazier’s foundation.

Every Therma-Tru job carries the Done Right Promise and the Keystone Standard - both manufacturer warranty layers registered in writing, with durations stated, before the truck leaves your driveway. We are also an authorized installer for PGT, CGI, CWS, and ES Windows, so if a Therma-Tru replacement does not fit the budget, we can quote you side-by-side on paper. The decision is yours, with real numbers.
FAQs
Yes. We order insulated glass units cut and bent to the exact radius or angle of your Therma-Tru frame, matched to the original glass package. This typically takes two to three weeks from order to install in Hialeah. Call (386) 977-5410 with the model number on the frame label and we will get you a written quote.
It depends on the part and the repair. We stay with OEM Therma-Tru components on visible frame and sash work to keep your warranty intact, and we use quality aftermarket parts only on internal hardware that the warranty would not cover anyway. As an independent Therma-Tru service provider, we do not claim any manufacturer authorization, but we do understand which repairs keep the warranty safe and which ones kill it. We will tell you plainly before any work begins.
Usually not. A fogged crescent or arch is a failed insulated glass unit, and we can replace just the glass in most Therma-Tru frames. You only need a full window replacement if the frame itself is cracked, rotted, warped, or the opening has settled out of square. We will inspect and tell you the truth, and the estimate is free.
Measurement takes 30 to 60 minutes at your home, glass and frame fabrication takes two to four weeks depending on the shape and glass package, and installation typically takes one day for a single unit. Larger jobs with multiple openings run two to three days. We will give you a written schedule before you commit.
Yes, when the job requires it under Miami-Dade building code. Impact-rated window installations and structural header work need permits, and we pull them and schedule the inspections. If it is a like-for-like replacement that the county does not require a permit for, we will tell you that too and quote accordingly.
