Therma-Tru Custom & Geometric Windows in Coral Springs: What to Know First
We service and install Therma-Tru custom and geometric windows in Coral Springs, including arched, radius, oval, and oversized openings. Most Therma-Tru custom & geometric jobs run between $1,800 and $6,400 per opening depending on glass package, frame material, and whether the opening requires structural rework. As an independent Therma-Tru service provider, we are not a Therma-Tru dealer and do not claim to be one, but we know these windows the way a mechanic knows a particular engine: where they hold up, where they give out, and what it takes to set them square.
This page is for Coral Springs homeowners who already have Therma-Tru windows, or who are considering them for a custom opening, and want straight answers about repair, replacement, and real costs. If you’re looking at a fogged arched window over the front entry or a radius unit that binds when the humidity climbs, call (727) 261-2215. A live person answers, and we’ll talk you through what you’re seeing.
How Therma-Tru Products Fail - and How We Fix Them
Therma-Tru built its name on fiberglass entry doors, but their window lines show up across Coral Springs homes, often paired with those same door systems or set into open foyers and transom walls. Here is what we actually see in the field:
- Therma-Tru Transom and Radius units losing their seal at the curve. Therma-Tru’s arched transoms and radius windows use bent frame stock and a curved insulated glass unit. The seal along the bottom arc carries more stress than on a square unit, and after eight to twelve years of Florida sun and humidity, the corner of the curve is where we first see fogging. The fix is a new curved IGU, not a whole new unit, when the frame is still sound.
- Weep-hole blockage in Therma-Tru casement and awning windows. Coral Springs sits on flat, low ground, and the summer storms roll in hard. Therma-Tru casement sidetrack weep slots are narrow, and once they clog with pollen, dust, and the fine sand that blows in from the Everglades, water pools inside the track and creeps under the sash. The symptom the homeowner notices is a musty smell or a water line on the interior sill. We clean the tracks, ream the weeps, and reset the sash with fresh drainage slope.
- Operator and hinge wear on Therma-Tru casement windows. On casement windows that face the afternoon sun in neighborhoods like Ramblewood or Maplewood, the hinge arms and crank gears take the brunt of repeated opening under load. A crank that spins without moving the sash is almost always a stripped gear, not a bad sash. Therma-Tru hardware varies by era, and some pre-2012 models use a gear set that is no longer in production. We stock several common aftermarket operators and will tell you honestly whether OEM hardware is worth the wait.
- Warp and binding on oversized geometric openings. A large triangular or trapezoid window over a staircase sees roof movement and truss uplift that square windows do not. On some Therma-Tru geometric units, the aluminum reinforcement inside the vinyl frame stops short of the corners, and that corner is exactly where we find a bow after a few years of truss shift. We check the rough opening for movement before assuming the window itself is the problem, because you cannot fix a window set into a moving hole by replacing the window.
- Film and mineral buildup on Therma-Tru glass in sprinkler zones. This one shows up in Coral Springs more than most places because so many homes run well or reclaimed water through sprinklers. Overspray hits the glass, evaporates, and leaves a mineral film that looks like the glass is failing from the inside. It is not a seal failure; it is hard-water etching. We can often restore the glass with the right cleaning compounds, saving the homeowner from buying a new sash they do not need.
Our Therma-Tru Custom & Geometric Windows Process
Here is how a Therma-Tru custom or geometric window job goes from first call to cleanup, done the TruePane way:
- 1
You call (727) 261-2215 and describe what you’re seeing. A live person answers. We ask about the window type, the age of the home, and whether the problem is visual, mechanical, or water-related. That tells us which technician to send.
- 2
We measure the opening twice, before anything else. On geometric windows, the rough opening is not always square anymore, and the measurements matter more than the brand. Dale Kessler reads every rough opening himself before he quotes it, which is why our customers rarely see a change order after the job starts.
- 3
We decide together: repair or replace, OEM or quality aftermarket. For a failed IGU in a sound frame, replacement glass is the honest call. For a frame that has racked or rotted, a full unit is the honest call. We show you parts options on paper, with prices, so you know what you are buying.
- 4
We do the work in one visit when the job allows. That means the old unit out, the new one set, shimmed, squared, and sealed. On custom geometric units, the glass is ordered to the exact radius and angle before we arrive, so we are not improvising on your front porch.
- 5
We test the window the way the weather tests it. We run water over the exterior on a hose setting that mimics a Coral Springs downpour, check the operation through a full cycle, and look for any light or air passage around the frame.
- 6
We register both warranty layers in writing before we leave. The Keystone Standard means the manufacturer warranty and our Done Right Promise are documented, with durations stated, before the truck pulls out of your driveway.
What Therma-Tru Custom & Geometric Windows Costs in Coral Springs
Straight numbers, because you should not have to guess. These are the ranges we see for Therma-Tru work across Coral Springs, including neighborhoods like Ramblewood, Cypress Run, and the Country Club area:
- Curved or radius IGU replacement (fogged glass, sound frame): $380 to $1,100 per unit, depending on radius and glass package
- Full arched or radius window replacement: $1,800 to $3,200 per opening
- Custom geometric unit (triangle, trapezoid, pentagon) replacement: $2,200 to $4,100 per unit
- Oversized opening with structural rework or new framing: $3,500 to $6,400 and up, depending on header work and load requirements
What moves the price: glass type (impact-rated Low-E adds cost), the radius or angle tolerances on the custom cut, frame material, and whether we find rot or movement in the rough opening once the old unit is out. We give written, line-item quotes so there are no surprise entries on the final bill. Call (727) 261-2215 for a free estimate, and we will come measure.
Why Coral Springs Homeowners Call TruePane Windows & Doors for Therma-Tru Work
We are a Coral Springs company in the way that matters: Dale Kessler grew up in Ramblewood, and the business has put down roots here on purpose. Our technicians are background-checked and uniformed, and they treat a customer’s home the way they would treat their own mother’s. Every job is backed by the Done Right Promise, which means if it is not done right, we make it right, no paperwork and no arguing.
We also carry the perspective that comes from being an authorized installer for more than a dozen manufacturer lines. When a Therma-Tru unit is not the right fix, or when its warranty math does not pencil out against the repair cost, we can quote PGT, CGI, CWS, or ES Windows side by side on paper. That comparison is part of the square deal we have built the company on: the homeowner sees exactly what they are buying, and why. If the pane is not true, the job is not done.
FAQs
No, not when the repair is done correctly. Independent glass replacement and hardware repair does not void a Therma-Tru warranty, provided the work does not modify the frame or the original installation in a way that causes the failure. We keep every Therma-Tru job within those bounds, and we register both warranty layers in writing so there is a paper trail if the manufacturer ever asks questions. Call (727) 261-2215 if you want us to check your specific unit.
Yes. We template every custom and geometric window on site, including radius, angle, and corner detail, and order the replacement glass or full unit to that exact template. The template is more accurate than a manufacturer’s drawing because it accounts for the way your house has settled since the original install. Call (727) 261-2215 and we will measure it right the first time.
Most custom Therma-Tru geometric and radius window replacements take one to three weeks from template to install, depending on glass lead time. Straight repair work on an existing frame is often same-day. We quote the timeline on paper before you commit, and we do not leave a job hanging between appointments. Call (727) 261-2215 for a specific date window on your job.
In most Coral Springs homes, if the frame is square and the sash is sound, replacing just the insulated glass unit is the better value. A new curved IGU runs $380 to $1,100, while a full replacement starts at around $1,800. If the frame has racked or the hardware is worn past service, replacement starts making more sense, and we will show you both numbers side by side.
It is our workmanship guarantee in writing. If the work is not done right, we make it right, no paperwork, no fine print, no arguing about who measured what. Both manufacturer warranty layers are registered and dated before the truck leaves the driveway, so you know exactly what is covered and for how long. That is The Keystone Standard, and it applies to every Therma-Tru job we do. Call (727) 261-2215 to schedule your free estimate.
