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

We install, replace, and service Therma-Tru custom and geometric windows throughout West Palm Beach, and most jobs are done in a single visit with labor quoted up front in writing. An arched or radius Therma-Tru unit with a failed seal or a binding sash typically runs $400 to $950 to repair, while a full custom geometric replacement lands between $1,200 and $3,400 depending on glass package, size, and frame condition. We are an independent Therma-Tru service provider, not a Therma-Tru dealer, which means we quote what the opening actually needs rather than what a sales catalog says fits. If you have a Therma-Tru window that is fogged, stiff, or out of square, call (561) 264-1279 and a live person will answer.

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

Therma-Tru is better known for its entry doors, which means its window lines carry a recurring problem: the frames are engineered for door-slab integration, not always for the racking and humidity loads of a south Florida wall opening. In West Palm Beach, we see the same failures repeat across specific product generations.

• Smooth-Star radius units with seal failure at the apex. The curved laminated glass in Smooth-Star radius windows is bent at the factory, and the apex of the bend is where the insulated glass seal lets go first. Years of afternoon sun on a west-facing wall in West Palm Beach accelerates it. We reglaze with curvature-matched IGUs rather than forcing a flat aftermarket unit into a radius frame, which is the shortcut that leaves a visible gap.
• Classic-Craft geometric sashes that bind after the house settles. Classic-Craft geometric windows, especially octagons and half-rounds, have sash rails that were milled tight from the factory. Once the rough opening moves even an eighth of an inch, the sash starts dragging. The fix is re-shimming the frame to reestablish the reveal, not sanding the sash, which voids Therma-Tru’s finish warranty.
• Therma-Tru casement geometries with stripped operator arms. The casement operator hardware on older Therma-Tru geometric units was sourced from a now-discontinued supplier. Homeowners strip the crank arm trying to force a warped sash closed, and the operator fails. We match the tooth count and throw length with a current aftermarket operator rather than telling the customer the window needs to be replaced.
• Transom and eyebrow windows with exterior trim rot at the lower chord. Therma-Tru’s round-top and eyebrow transoms use a trim board at the base of the curve where water pools after a West Palm Beach afternoon storm. Once the paint film cracks, the composite absorbs moisture and swells. We cut the rot, refit with a PVC shoe, and re-flash the sill so the same repair is not needed again in three years.
• Oversized geometric picture windows that ship with undersized glazing beads. On Therma-Tru’s larger fixed geometric units, the factory glazing bead is a single-piece vinyl extrusion that shrinks slightly over time in south Florida heat. The bead pulls away at the corners, letting air and water through. We replace it with a color-matched bead cut to the actual opening dimensions, which is a detail the factory spec sheet does not cover.

Our Therma-Tru Custom & Geometric Windows Process

Here is how a typical Therma-Tru job goes when you call (561) 264-1279.

1. 1
   The call. A live person answers. We ask what the window is doing, not just what brand it is. If you have the original order paperwork, we pull the dimensions from it. If not, we measure on site.
2. 2
   Twin measurement. A background-checked technician measures the opening twice, checks the frame for square with a level and diagonal tape, and notes the reveal on all four sides. If the frame has racked, we say so before quoting anything.
3. 3
   The parts decision. We quote OEM Therma-Tru parts when they are the right call and current production when OEM supply is backordered or discontinued. You see both options on paper, side by side, with prices.
4. 4
   The written quote. Fixed price, line by line. No allowances, no “may increase” language. If we find hidden damage during the job, we stop and show you before spending another dollar.
5. 5
   The install or repair. Uniformed techs set the unit plumb and square, seal the perimeter, and tool the caulk joint clean. We register both warranty layers in writing before the truck leaves the driveway.
6. 6
   The Done Right walk. We open and close every sash, run a water check on the exterior, and have you do the same. If it is not square, plumb, and sealed, it is not done. That is the standard on the first visit and the baseline for every callback.

What Therma-Tru Custom & Geometric Windows Costs in West Palm Beach

Honest numbers for Therma-Tru work in the West Palm Beach market, based on what we have actually billed over the last several years:

• Glass seal replacement, fixed geometric unit: $380 to $650 per lite, depending on glass size and whether it is curved or flat
• Sash re-shim and square (binding Classic-Craft or Smooth-Star unit): $280 to $520 with new shims and re-sealing
• Full replacement of a custom radius or geometric Therma-Tru window: $1,200 to $3,400 installed for standard impact-rated glass, more for oversized or laminated upgrades
• OEM hardware replacement (casement operator, locking handle): $90 to $260, parts and labor together

What moves the price: whether the glass is curved or flat, the overall width of the rough opening, access to the exterior side of the frame, and whether the original sash can be saved or must be re-milled. The estimate is free and the number we quote is the number you pay. Call (561) 264-1279 and we will put it in writing.
