Therma-Tru Custom & Geometric Windows in Delray Beach: What to Know First

Therma-Tru custom and geometric windows in Delray Beach are typically repaired or replaced within one to two weeks of your first call, depending on whether we are matching an existing fiberglass line or ordering a full custom unit. TruePane Windows & Doors is an independent Therma-Tru service provider, not a manufacturer-authorized shop, which means we quote honestly on both OEM and quality aftermarket parts without a brand script. Most geometric window jobs in this area run between $850 and $4,200, and we will put the number in writing before any work begins.

If you own a Therma-Tru radius window, eyebrow arch, or oversized trapezoid that has started to fog, bind, or leak around the frame, this page lays out exactly what we see in Delray Beach homes, what causes it, and how we fix it. Call (561) 940-2917 and a live person answers, day or night.

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

• SlimLine radius and eyebrow units losing their seal. Therma-Tru’s SlimLine series uses a narrow fiberglass frame profile that looks clean on arched openings but leaves very little room for thermal expansion. In Delray Beach, the combination of salt air and afternoon heat cycling pulls the glass-to-frame seal apart faster than on a full-width frame. We see fogged eyebrows on homes off Linton Boulevard and in Lake Ida every month. The fix is a complete reglaze with a marine-grade sealant, not a patch, and we will tell you if the sash itself is sound enough to keep.
• Geometric windows binding in the frame after settlement. Shaped windows (trapezoids, octagons, half-rounds) put uneven load on the frame corners. With Therma-Tru’s fiberglass line, the corners are mechanically fastened, and over two decades of Florida humidity the fasteners can work loose enough to let the sash drop a few millimeters. The window still looks fine but will not open or close without forcing it. We square the rough opening, reset the fasteners, and re-shim the unit so the load distributes evenly.
• Water intrusion at the arched top of radius units. Many Delray Beach homes with Therma-Tru radius windows were flashed with builder-grade tape that fails in the intense UV exposure we get here. The arch is the first place water shows up, and by the time the homeowner sees a stain on the drywall, the sill pan has been wet for a season or more. We pull the unit, inspect the opening, install a proper sill pan and flashing system rated for coastal Florida, and reset the window as an independent Therma-Tru service provider.
• Hollow-core interior trim cracking on shaped windows. Therma-Tru bundles a lot of their geometric units with a composite interior trim that looks like wood but does not hold paint well in humid rooms. Kitchens and bathrooms in Delray Beach show this first, with cracking at the joints where the radius meets the straight runs. We replace the trim with solid PVC or real wood, primed correctly for a humid climate, so the joint does not reopen in a year.
• Oversized openings with under-engineered support. When a Delray Beach home has a Therma-Tru oversized trapezoid or a large arched transom, the original builder sometimes did not add the required structural header support because the window was ordered late in the project. The result is a window that bows slightly, cracks the exterior caulk line, and lets air in around the perimeter. We add the structural support, re-flash, and reset the window. This is the most expensive repair we do on Therma-Tru lines, and usually the most necessary.

Our Therma-Tru Custom & Geometric Windows Process

Here is how a Therma-Tru job runs with us, from first phone call to final walkthrough:

1. 1
   You call, a person answers. You describe the window, the symptoms, and where the house sits. We ask about the age of the unit and whether you have any paperwork from the original install.
2. 2
   We schedule the site visit. A background-checked, uniformed technician meets you at the house, measures the opening twice, and inspects the frame, glass, sill, and flashing. We take photos before touching anything.
3. 3
   We write the diagnosis on paper. You get the failure explained plainly, the repair options laid out side by side including OEM Therma-Tru parts versus quality aftermarket, and a price for each path. If it is a replace, we quote the exact unit specified.
4. 4
   We do the work. Most single-window repairs happen in one visit. For full custom replacements with odd angles or oversized glass, we order and return within one to two weeks. Technicians wear uniforms, backgrounds are checked, and the opening gets measured again before the new unit goes in.
5. 5
   We test and we document. Water test on exterior sealed joints, operation test on the sash, and a final inspection against the original work order. Both manufacturer warranty layers are registered in writing before the truck leaves, if a new unit is involved.
6. 6
   The ninety days after. If anything is not done right, we come back and make it right. No paperwork fight, no fine print. That is the Done Right Promise.

What Therma-Tru Custom & Geometric Windows Costs in Delray Beach

Straight numbers help, so here is what Therma-Tru custom and geometric work runs in the Delray Beach market:

• Reglaze a fogged SlimLine eyebrow or radius unit: $850 to $1,900 depending on glass package and access.
• Reset and re-flash a single geometric window (trapezoid, half-round, octagon): $1,100 to $2,600 including sill pan replacement.
• Full replacement of an arched or curved Therma-Tru unit with a new custom fiberglass window: $2,400 to $4,200 for typical residential sizes.
• Oversized or second-story shaped windows: add 30 to 45 percent for access equipment and structural support.

What moves the price is access, glass type (impact-rated costs more), whether the opening needs structural work, and whether the existing frame can be reused or must come out entirely. We write every quote as a fixed number. No change orders after the fact, no surprise line items. If it is not in writing, it is not a guarantee, it is a conversation.

Why Delray Beach Homeowners Call TruePane Windows & Doors for Therma-Tru Work

We have served this community since 2008 through a craft tradition that started with Dale Kessler, who grew up in the Lake Ida neighborhood and spent his early years watching his father repair storefronts along Atlantic Avenue. TruePane was founded in 2008 on a simple rule: if the pane is not true, the job is not done. That governs every Therma-Tru custom and geometric window we touch. Our techs are trained to work on more than a dozen manufacturer lines including PGT, CGI, CWS, and ES Windows, so when a Therma-Tru unit is better served by a different replacement product, we quote them side by side on paper and let you decide with full information. We stand behind the work with the Done Right Promise and The Keystone Standard: both manufacturer warranty layers registered in writing, durations stated, before the truck leaves your driveway.
