PGT Custom & Geometric Windows in Boca Raton: What to Know First
We provide independent PGT custom and geometric window service in Boca Raton, from arched impact units in Royal Palm Yacht & Country Club to oversized geometric assemblies in Boca West. Most measured surveys are scheduled within 48 hours, and the written quote you receive is the price on the invoice - Haven Clause 1, no exceptions. Custom PGT work runs $2,800-$7,500 depending on glass package, shape complexity, and whether the opening needs reframing.
This page is for homeowners who already own PGT windows and need custom or geometric shapes replaced, upgraded, or repaired - or for those specifying new PGT custom units and want an installer who documents every measurement before ordering. Call (561) 200-8592 to schedule your measured survey. “Measure it twice, write it down, then we can talk price.”
How PGT Products Fail - and How We Fix Them
- WinGuard laminated seal degradation in arched tops. The curved geometry of WinGuard Architectural Series half-rounds concentrates thermal stress at the springline, where the laminated glass meets the anodized frame. In Boca Raton’s salt-air corridor, we’ve tracked seal failures at 8-12 years, not the 15+ you’d expect inland. We replace with OEM laminated glass specified to PGT’s 2020+ interlayer standard, or source from Cardinal’s LoĒ-366 line when the project calls for better SHGC.
- PGT EnergyVue geometric sash warping. The thinner vinyl profiles in EnergyVue custom shapes - particularly trapezoids and octagons - can rack out of square when the rough opening wasn’t plumbed for the specific geometry. Sonia Raman and her crew see this in 2016-2019 Boca Raton builds where the framer treated a geometric window like a standard rectangle. We measure diagonals to 1/16″, rebuild or shim the subsill as documented evidence, and reorder only after the opening is verified.
- Custom aluminum frame galvanic corrosion at miter joints. PGT’s pre-2018 aluminum custom shapes used a dissimilar metal clip at the miter that reacts with Boca Raton’s coastal atmosphere. The symptom looks like paint bubbling at the corner; the cause is corrosion under the finish. We strip to substrate, treat with chromate conversion coating, and reassemble with stainless hardware - or spec CGI’s 575 Series if the customer wants to change brands entirely.
- Oversized PGT unit structural deflection. Custom picture windows over 72″ wide in the WinGuard line require intermediate support that some installers omit to save trim work. The glass doesn’t fail; the frame does, showing a visible bow at center. We add PGT-approved mullion posts or split the opening into a true divided-lite configuration, documented in the photo record you keep.
- Geometric hardware mismatch on retrofits. PGT changed its roto operator spline in 2021, and custom shapes often ship with newer hardware than the adjacent standard windows. The old crank won’t fit the new sash. We inventory both spline profiles and match by production date, not by “looks close enough.”
Our PGT Custom & Geometric Windows Process

- 1
Measured survey you keep. We document every opening in a written scope: rough width, rough height, diagonal check, sill level, and sightline clearance. You get a copy before we leave.
- 2
Diagnostics with photo evidence. Failed seal, frame deflection, or hardware issue - we photograph the condition and note the PGT series, glass stamp, and production markings visible on the spacer bar.
- 3
Parts decision: OEM or verified equivalent. For warranty-active units, we source PGT OEM. For out-of-warranty work, we may spec ES Windows or ECO Window Systems equivalents with matching DP ratings and U-factors, documented in writing.
- 4
Written price before any work starts. Haven Clause 1. The measured survey and the quote are the same document. No change orders.
- 5
Installation by verified crew. License numbers on record, uniformed, background-checked - Haven Clause 3. For custom shapes, the same tech who measured installs; no handoffs.
- 6
Test, photo record, warranty. Operate every sash. Flash-test seals. Document with dated photos. Activate your 365-Day Done Right Promise.

Why Boca Raton Homeowners Call Sightline Windows & Doors Boca Raton for PGT Work

We’ve installed and serviced PGT, CGI, CWS, ES Windows, and ECO Window Systems across Boca Raton since 2012 - including that run of impact-rated sliding door replacements in Broken Sound where every rough opening needed reframing for current code. The Haven Standard governs every job: written price first, verified crew, evidence on every visit, no surprises.
If PGT lead times stretch or a series is discontinued, we specify from our other seven lines by performance tier, not by what we have in stock. The 365-Day Done Right Promise is stamped on every contract, not offered as a courtesy. Calls are answered live, 24/7.
FAQs
No - PGT’s warranty covers manufacturing defects regardless of who installs or services the unit, provided the work doesn’t damage the product. We document every step so warranty claims are clean. For warranty-active jobs, we use PGT OEM parts and note serial numbers in your file. Call (561) 200-8592 to schedule.
Typically 4-6 weeks for custom shapes, with 2-3 weeks for standard geometric sizes in stock configurations. The measured survey happens within 48 hours of your call; fabrication time is fixed by PGT’s queue. We don’t quote install dates until the unit is in our warehouse and inspected. Call (561) 200-8592 to start the survey.
Yes, if the series is still in production. We record the glass stamp, frame finish code, and grille pattern from your existing unit and cross-reference PGT’s current catalog. For discontinued series, we source the closest CGI or CWS equivalent and document the match criteria in writing. Call (561) 200-8592 for a free second opinion on any approach.
We replace when the frame is compromised, the glass package is obsolete, or repair costs exceed 60% of replacement. We repair for isolated seal failures with sound frames, hardware issues, or sash-specific problems. The decision is in writing, with both options priced, before you commit. Call (561) 200-8592 to schedule diagnostics.
Yes, for any replacement that alters the opening size or changes the impact rating. Boca Raton Building Department requires permits for impact-rated modifications and final inspection for HVHZ compliance. We pull permits, schedule inspections, and pass them - documented in your photo record. Call (561) 200-8592 to confirm your project’s permit status.
