Therma-Tru Custom & Geometric Windows in Greenacres: What to Know First
We install and service custom and geometric Therma-Tru windows for homeowners in Greenacres, and most jobs are measured, built, and installed within three to four weeks. As an independent Therma-Tru service provider, we work on arched, radius, eyebrow, and oversized openings that box-store windows cannot touch. Call (754) 339-0784 and we’ll send a technician who has set more custom Therma-Tru openings in Palm Beach County than he can count.
This page is for Greenacres homeowners who own Therma-Tru windows and doors, or who want them, and need a shaped opening done right. If you live in the 33413, 33415, or 33463 zip codes, we work your neighborhood weekly. You are not getting a salesperson. You are getting a glazier who knows what a Greenacres thunderstorm does to a badly sealed radius window.
How Therma-Tru Products Fail, and How We Fix Them
Therma-Tru builds a solid window in its base and mid lines, but shaped openings put stress on every component. Here is what we find in Greenacres homes, and what we do about it:
- Radius and eyebrow units pulling away at the head. Therma-Tru’s arched casement and radius fixed units carry more glass area than the frame was originally jigged for in some production years. The weight of an arched top settles, and the frame corners creep. In Greenacres humidity, the exterior sealant fails at the crown first, before you see it from inside. We pull the unit, true the rough opening, reset the frame with fresh flashing and a drainage plane, and the bow disappears.
- Condensation fogging between panes on geometric picture windows. Therma-Tru’s insulated glass units on custom shapes, especially the trapezoid and pentagon configurations, rely on a perimeter spacer that flexes under Florida sun. Once the spacer kinks, the argon or krypton escapes and you get a fogged seal. Therma-Tru’s factory warranty covers glass seal failure for a stated term, but only if the unit was registered. We see unregistered units all over Greenacres. We source correct replacement IGUs, clock-glass matched where needed, and register the new unit so the warranty is live from day one.
- Operable geometric casements binding after rough-openings shift. A Greenacres slab home on sandy fill moves. A circular-top casement will bind at the top hinge before a rectangle ever does. We re-square the sash, shim the frame properly, and use a torque-calibrated driver so the hinge screws do not pull the jamb out of true. The previous installer usually just filed the strike plate. That is not a fix.
- Millions of hot sun on curved mullions. Therma-Tru’s multi-light geometric units use mullions that expand and contract at a different rate than the glass. After enough summers, the mullion beads separate and water gets in at the joints. We replace with the OEM profile or a true-match aftermarket extrusion, bedded in high-tack sealant, and painted on a jig so the finish does not look touched.
- Improper flashing around custom transoms over doors. Transom windows above a Therma-Tru entry door in Greenacres take wind-driven rain sideways during summer squalls. Most installs we see were flashed like a standard window, not like a unit sitting directly over a door opening. We re-flash with pan flashing that drains out, not in, and the drip edge goes on before the siding. That detail is why the sill does not rot.
Our Therma-Tru Custom & Geometric Windows Process
Here is how a Greenacres Therma-Tru custom window job goes with us, from the first call to the final walkaround:
- 1
You call (754) 339-0784. A person answers. You tell us what the window does, or what it looks like when the wind blows. We ask for rough measurements if you know them, and we book a visit that fits your week, not ours.
- 2
We measure the opening twice. Twice, every time. Rough opening width, height, diagonal, square, and the condition of the king and jack studs. On a shaped opening, we also trace the template on site and note every deviation from a true radius or angle. Dale Kessler taught every technician the same rule: read the opening before you touch a tape measure.
- 3
We decide parts on paper with you. For a repair, we tell you what is OEM Therma-Tru, what is a quality aftermarket match, what each costs, and what the warranty is on both. No surprises on the bill later. For a new custom unit, we quote the exact shape, glass package, frame color, and grid pattern in writing.
- 4
We install, flash, level, and seal. The unit goes in square, not just “close enough.” We use composite shims, not wood scraps from the truck. We flash the head, the sill, and the jambs. Every screw is set to spec. Every frame joint is sealed before the interior trim goes back.
- 5
We test and register. We open and close every operable sash a dozen times. We check the seal lines with bright light. Then we register both warranty layers in writing, in front of you, with the durations stated. If the pane is not true, the job is not done.
- 6
We leave your threshold clean. Drop cloths come up, glass fragments get swept, and the only sign we were there is a window that finally works.
What Therma-Tru Custom & Geometric Windows Cost in Greenacres
Custom shape work costs more than stock, and we do not pretend otherwise. What you pay depends on the shape, the glass package, the frame material, and whether we are repairing an existing Therma-Tru unit or building new. Here are realistic figures for Greenacres, based on jobs we’ve done in the city:
- Reglaze a fogged geometric fixed window (single IGU): $290-$540
- Reseal and re-flash a leaking arched Therma-Tru unit, including trim reset: $420-$780
- New custom half-round or eyebrow fixed window, standard insulated glass, mid-range frame: $900-$2,200
- New circular-top casement with operable sash and high-performance glass: $1,400-$3,100
- Oversized trapezoid or pentagon unit with impact-rated glass, installed and flashed: $2,800-$6,500
Crucial variable: if the original rough opening was never framed correctly, we have to correct the framing before we set the unit. Greenacres homes from the 1990s and early 2000s often have openings that were cut fast. That is a labor line on the estimate, and we tell you about it before we start, not after. Call (754) 339-0784 and we’ll measure the opening and put a written, line-item quote in your hand. Estimates are free.

FAQs
Most fogged, leaking, or binding Therma-Tru geometric windows in Greenacres can be repaired by replacing the glass unit, re-flashing the opening, or re-squaring the sash, which costs half or less of a full replacement. Replacement only makes sense when the frame itself is rotted or broken beyond structural integrity. Call (754) 339-0784 and we’ll tell you which one you have after we open it up.
Therma-Tru covers insulated glass seal failure and some frame issues for a stated term, but only if the original unit was registered, and the coverage can be voided by an out-of-true installation. We register every unit we install, and we will look up your existing registration if you have the paperwork. An exact answer for your unit takes one phone call at (754) 339-0784.
Most custom and geometric Therma-Tru units take three to four weeks from measurement to installation, depending on the glass package and whether the shape is stock-custom or full-custom. Rush orders are possible on some lines for an additional factory fee. Call (754) 339-0784 and we’ll give you a real production date, not an estimate of an estimate.
Yes, when the scope requires it. A same-size replacement of a single window typically does not need a permit in Greenacres, but an oversized opening, a structural header change, or an impact-rated retrofit usually does. We pull the permit, and we are on site for the inspection. If the pane is not true, the job is not done, and we do not call it done until the inspector says it passes.
No, unless we find something inside the wall that we could not see before opening it, and even then we stop, show you, and get your written approval before spending another dollar. We do not run change orders for things we should have caught at measurement. That is what measuring twice is for.
