AfterTherma-Tru Custom & Geometric Windows in Weston: What to Know First
We provide independent Therma-Tru custom and geometric window service in Weston, from arched and curved units to oversized openings and specialty shapes. Most custom Therma-Tru orders run 4-6 weeks for fabrication, with installation scheduled once the unit clears our pre-arrival inspection. Our written quote, delivered after the measured survey, is the same document that governs the final invoice - no change orders, no surprises.
This page is for Weston homeowners who already own Therma-Tru windows and need a replacement, repair, or new custom opening filled - or who are comparing Therma-Tru against PGT, CGI, CWS, and ES Windows for a shaped or oversized installation. Call (754) 812-9260 to schedule your measured survey. The written price follows.
How Therma-Tru Products Fail - and How We Fix Them
- Classic-Craft arched top lights develop seal creep in Weston’s humidity. The curved rail in the Classic-Craft CA2868 and CA2872 series carries a thermal break that can gap when seasonal expansion exceeds the butyl bead’s tolerance. We see this most in Weston homes west of Bonaventure Boulevard where afternoon heat buildup is severe. Our fix: full sash removal, clean-back to bare frame, and re-glazing with a hybrid silicone-polyurethane seal rated for 150% joint movement. We document the before condition with frame-read photos the customer keeps.
- Smooth-Star geometric units show corner delamination on trapezoid and pentagon configurations. The welded corners in Smooth-Star’s shaped line - particularly the 15° and 22.5° miter cuts - stress differently than standard 90° joints. The vinyl can cold-flow at the weld nub over five to seven Florida summers. We cut back to sound material, sleeve the joint with an aluminum corner key on impact-rated jobs, and re-weld with a heat-profile matched to Therma-Tru’s original spec. OEM corner keys are available; we stock the common angles to avoid a parts hold.
- Fiber-Classic oversized units sag at the header on openings over 72″ wide. The pultruded fiberglass in Fiber-Classic is stiff but not immune to dead-load deflection when the original installer skipped the structural support bracket. We’ve corrected three of these in Weston Hills alone, all with the same omission: no LVL or steel header reinforcement behind the fin. Our fix is structural first - we bring in a licensed framer if needed - then set the unit on a bed of setting block and cap bead, checked for level at three reference points. Measure it right the first time. The window does not care how confident you were.
- Therma-Tru impact-rated custom shapes lose their DP rating when aftermarket glass is substituted. The DP-50 rating on Therma-Tru’s impact geometric line depends on the laminated lite being sourced from their approved IG fabricator list. We’ve seen independent glaziers swap in generic SentryGlas without updating the NOA, which voids the wind-borne debris certification. We source through Therma-Tru’s verified supply chain or, when the OEM lead is excessive, we document the substitute with a Florida Product Approval cross-reference letter. The customer gets the paperwork.
- Direct-Set picture units in coastal Weston develop weep-path blockage from salt crust. The minimal frame profile on Direct-Set custom shapes leaves a narrow weep channel that crystallizes shut with salt accumulation - particularly on second-story installations catching the easterly flow off the Everglades. Water ponds in the sill track and rots the sub-sill. Our fix: disassembly, ultrasonic cleaning of the weep system, replacement of any corroded hardware with 316 stainless, and a modified weep cover with larger free area. We photo-document the corrosion stage so the homeowner understands why cleaning alone wasn’t sufficient.
Our Therma-Tru Custom & Geometric Windows Process
- 1
Measured survey. Sonia Raman or a senior tech arrives with a laser measure, level, and the printed Therma-Tru sizing matrix for the series in question. The customer receives the marked-up dimension sheet before we leave. This is Haven Clause 1: Have it in writing.
- 2
Diagnostics and parts decision. We identify the series, manufacturing date (stamped on the spacer bar or etched in the corner lite), and whether OEM or quality aftermarket parts are appropriate. Some Therma-Tru geometric hardware is on 8-10 week backorder; we maintain relationships with two aftermarket machine shops that reproduce the critical profiles.
- 3
Written quote, same document. The measured survey becomes the scope of work. Price, timeline, and warranty terms are fixed. The customer signs once.
- 4
Fabrication and pre-arrival inspection. For custom orders, we inspect the unit at our receiving bay before scheduling installation. We’ve rejected three units in the past eighteen months for geometric tolerance issues - out-of-square arched frames that would have failed our three-point check.
- 5
Installation and live testing. The crew arrives uniformed, with license numbers provided in advance per Haven Clause 3. We set, seal, and operate every moving part. Impact units get a post-installation deflection check.
- 6
Photo record and 365-Day Done Right Promise. The customer receives a link to time-stamped installation photos and the written warranty document. If it’s not done right, we make it right - stamped on every job, not offered as a courtesy.

AfterWhat Therma-Tru Custom & Geometric Windows Costs in Weston
These are the price ranges we have written on Therma-Tru custom and geometric jobs in Weston over the past twenty-four months. Every job starts with our free measured survey; these figures are for planning, not quoting.
| Scenario | Typical Range |
|---|---|
| Smooth-Star geometric replacement (trapezoid, pentagon, circle-top) | $1,800 - $3,400 per opening |
| Classic-Craft arched top light, seal repair/re-glaze | $680 - $1,200 |
| Fiber-Classic oversized unit (72″+ wide), full replacement with structural correction | $4,200 - $6,800 |
| Direct-Set custom shape, weep system rebuild and hardware replacement | $920 - $1,650 |
| Impact-rated geometric, full unit with DP-50 certification documentation | $2,800 - $5,200 per opening |
What moves the price: unit size, whether the original frame is reusable, structural correction requirements, and whether the glass package needs to match an existing low-E coating for HOA compliance. Weston has seven active HOAs with specific tint and reflectivity rules; we verify against the governing documents before ordering. Call (754) 812-9260 for your written estimate - the measured survey is free, and the price we write is the price you pay.
Why Weston Homeowners Call Sightline Windows & Doors Weston for Therma-Tru Work
We are not a Therma-Tru dealer. We are an independent Therma-Tru service provider with eighteen thousand documented openings since 2012, and we carry eight manufacturer lines - PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux - so we can specify what the opening requires rather than what is in stock.
The Haven Standard governs every engagement. Haven Clause 1: the written price before any work starts. Haven Clause 3: verified crews, background-checked, with license numbers provided before arrival. Haven Clause 4: evidence on every job, the photo record you keep. The 365-Day Done Right Promise is not a courtesy; it is stamped on every completion document.
Our Weston customers tend to be methodical. They read three-star reviews. They want prices on the page. They text us photos of their failing unit and we respond with what we found, not what we felt about it. That is the customer we built this company for.
FAQs
It depends on the series age and whether the repair used OEM-specified parts and methods. Therma-Tru’s original warranty on fiberglass and steel units runs twenty years on the frame and five on the hardware, but it excludes damage from improper installation - which is what we often find in Weston geometric jobs. We document the original installation condition with photos so you have evidence if a warranty claim is viable. For units past warranty, our repair carries its own one-year workmanship guarantee. Call (754) 812-9260 and we’ll review your specific unit.
Four to six weeks for standard custom shapes; eight to ten weeks if the unit requires a non-standard radius or if the glass package is on allocation. We do not promise expedited fabrication - the lead time is the lead time - but we do hold the unit at our receiving bay for pre-installation inspection so you are not waiting for a re-order. The installation itself is typically one day for a single opening, two days for oversized or multi-unit jobs.
Usually, yes, but with caveats. Therma-Tru has updated its color formulations twice since 2018; the “Pebble” fiberglass finish from 2016 does not match the current batch. We maintain a library of retired color chips and can order custom-matched paint through our finisher, but we will tell you honestly if the match will be acceptable at ten feet versus acceptable at arm’s length. The customer gets that assessment in writing before we proceed.
Repair when the frame is sound and the failure is isolated to seal, hardware, or glass. Replace when the frame shows deflection, the corner welds are cracking, or the unit is pre-2010 and parts are obsolete. We have recommended repair on roughly forty percent of the Therma-Tru geometric calls we’ve run in Weston - we are not in the business of selling units that don’t need selling. The measured survey includes our recommendation and the price for both paths, so you decide from documented information.
Yes, when the replacement alters the opening size, changes the egress configuration, or involves impact-rated installation in a wind-borne debris region. Weston falls under Broward County’s amended Florida Building Code; permit requirements are strict and inspection failures are expensive. We pull the permit, schedule the inspection, and correct any punch items at our cost. The permit documentation is included in your job packet. Call (754) 812-9260 to schedule your measured survey - estimates are free.
