AfterTherma-Tru Custom & Geometric Windows in West Palm Beach: What to Know First
As an independent Therma-Tru service provider in West Palm Beach, we measure, order, and install custom and geometric windows from Therma-Tru’s current and legacy lines, with most projects quoted within 48 hours of survey and installed on a scheduled date we commit to in writing. If the number isn’t on the page, it isn’t in the price - Haven Clause 1 means your written quote and your final invoice are the same document. This page is for Therma-Tru owners in West Palm Beach, Lake Worth, and along Flagler Drive who need arched, circular, trapezoid, or oversized custom windows and want the price named before anyone picks up a tool. Call (561) 354-3861 to schedule your free measured survey.
How Therma-Tru Products Fail - and How We Fix Them
- Decorative glass delamination in Classic-Craft Canvas and Fiber-Classic collections. The simulated divided lite (SDL) grilles and beveled glass clusters in these entry door systems trap moisture at the glazing edge when the butyl seal degrades. In West Palm Beach, the salt air and afternoon thunderstorms accelerate this. We remove the sash, document the seal failure with photos, and specify OEM replacement insulated glass units rather than field-reglazing, which voids the glass warranty.
- Structural sag in arched transoms from the 2014-2019 Therma-Tru Arch Kit program. The aluminum reinforcement channel in these units was undersized for spans over 48 inches in high-wind zones. We find the telltale corner gap at the springline during survey, specify a heavier-gauge replacement frame from Therma-Tru’s current Impact Arch system, and sister the rough opening if needed.
- Impact-rated geometric window fastener corrosion in coastal installations. Therma-Tru’s 3-point locking hardware on impact-rated custom shapes uses zinc-coated fasteners that weep rust in salt-air environments within 7-10 years. We replace with 316 stainless steel equivalents, document the fastener grade in your photo record, and note the change on your warranty paperwork.
- Thermal stress cracks in oversized rectangular units from the 2016-2020 Direct Set line. These fixed custom windows lacked expansion clearance in frames over 60 inches when installed with rigid foam backer. We cut back the foam, install a compressible backer rod and silicone joint, and replace the glass with a heat-strengthened lite rated for the exposure.
- Rot at the sill of full-lite custom doors with integral transoms. The weep system in Therma-Tru’s 8’0″ full-lite units with half-round transoms clogs with Florida sand and insect debris. We rod the weeps, replace the sill pan with a sloped pan flashing, and install insect-resistant weep baffles - not caulk, which traps water.
Our Therma-Tru Custom & Geometric Windows Process
- 1
Measured survey you keep. We arrive with a laser measure, a moisture meter, and a camera. Sonia Raman or a verified crew member records rough opening dimensions, sightline clearances, and existing frame condition. You receive the marked drawing before we leave.
- 2
Diagnosis and parts decision. We identify your Therma-Tru series by the etch mark in the glass corner or the frame stamp. OEM glass, sash, or frame components are specified when available; when Therma-Tru has discontinued a profile, we source from a verified aftermarket supplier and note the substitution in writing.
- 3
Written scope and fixed price. The quote lists every line item - material, labor, disposal, permit if required - and states what is not included. You sign once. The price does not change.
- 4
Scheduled install with verified crew. Haven Clause 3: your technician’s license number is provided before arrival. We protect floors, remove the unit, install the replacement, and shim to plumb within 1/8 inch over the height.
- 5
Testing and documentation. We operate every sash, verify lock engagement, and check weep flow with a water test. You receive a dated photo record of the completed work and the 365-Day Done Right Promise in writing.
- 6
Cleanup and final invoice. The invoice matches the quote line for line. No change orders, no surprises.

We have installed and serviced Therma-Tru products in West Palm Beach since 2012, and we stock no inventory - every unit is specified to the opening, not sold from a warehouse.

Our crews are background-checked, uniformed, and identified by license number before they arrive. Live phone coverage is available 24/7 - you will reach a person, not a queue.
FAQs
No - as an independent Therma-Tru service provider, we use OEM parts where available and document every component by serial number. The glass and frame warranties remain intact; our workmanship is guaranteed separately under the Haven Standard.
Most Therma-Tru custom units require 4-6 weeks from survey to install, with the install itself completed in one scheduled day. Complex shapes or impact-rated glass may extend lead time; we state the expected date in writing at quote.
Yes, if Therma-Tru still produces the profile. We photograph your existing grille width, shadow box depth, and glass etch pattern, then order from the current catalog or specify a custom shop build. If an exact match is impossible, we show you the sample before ordering.
Replace, if the frame shows rot or the glass is delaminated. Field repairs on integrated transom systems rarely last in West Palm Beach’s wet climate; we specify a new unit with updated weep design and a sloped sill pan. Call (561) 354-3861 and we will assess at no charge.
Yes, when the scope triggers Florida Building Code requirements - typically for impact-rated replacements, structural modifications, or openings over 48 square feet. We pull the permit, schedule inspection, and pass it. The permit cost is listed in your written quote.
