PGT Custom & Geometric Windows in Lantana: What to Know First
As an independent PGT service provider in Lantana, we measure, order, and install PGT custom and geometric windows with written pricing delivered before any work starts - typically 4-6 weeks from survey to installation for standard custom shapes, 8-10 weeks for oversized or radius units. Our PGT jobs in Lantana run from $2,800 for a single arched impact window to $18,000+ for full-opening geometric assemblies on oceanfront homes.
This page is for Lantana homeowners who already own PGT products or are specifying them for new construction or renovation - and need a crew that knows the difference between a Winguard Architectural fixed geometric and a WinVue custom radius without reading the label twice. Call (561) 461-2062 to schedule your free measured survey. You’ll keep the document; the written quote will match it exactly.
How PGT Products Fail - and How We Fix Them
- Winguard Aluminum fixed geometric windows: The thermal break in the frame separates at the weld corners on radius tops after 6-8 years of Lantana’s salt-air exposure, especially on east-facing elevations within a quarter-mile of the beach. We see this on Hypoluxo Island and the beachfront corridor. Our fix: remove the sash, re-weld the corner with PGT-specified 6063-T6 alloy, and reinstall with new glazing tape - not silicone, which voids the thermal-break warranty.
- WinVue vinyl custom shapes: The narrow stiles on trapezoid and pentagon units rack out of square during installation because the vinyl profile lacks the aluminum reinforcement channel found in Winguard. We measure diagonals to 1/16″ before ordering and install with temporary bracing until the sealant cures - skipping this step is why we get callback requests on other installers’ WinVue jobs.
- Winguard Architectural oversized fixed units: The laminated glass plies delaminate at the edges when the setting block is omitted or placed off-center, a mistake we trace to crews who treat a 96″ x 120″ unit like a standard double-hung. We use PGT’s specified setting-block schedule - two blocks minimum, spaced at quarter points - and photograph placement before the bead goes in, per Haven Clause 4.
- Custom radius top windows (all PGT lines): The radius template supplied by PGT is cut from the architectural drawing, not field-verified, and Lantana’s block-and-stucco construction often deviates 3/8″ or more from plan. We build our own radius template on-site with 1/4″ lauan, test-fit it dry, and fax the verified profile to PGT’s custom shop - this adds three days to the order but eliminates the $1,200+ cost of a mis-cut unit.
- PGT impact-rated geometric units with integrated blinds: The cordless lift mechanism binds in trapezoid and triangle shapes because the tilt rail geometry changes across the slope. PGT’s OEM blind insert is the only repair option - aftermarket blind retrofits lack the impact-rated clearance and will interfere with the glazing bead. We order the OEM insert by PGT part number and document the old unit’s serial before removal.
Our PGT Custom & Geometric Windows Process

- 1
Measured survey you keep. Sonia Raman or a verified crew lead arrives with a laser measure and rough-opening checklist. We record frame squareness, wall thickness, and exposure - east-facing salt-air in Lantana gets noted for hardware specification.
- 2
PGT series identification and diagnostics. We locate the PGT serial label (usually on the hinge stile or head jamb) to confirm the exact series, glass package, and original order date - this determines warranty status and available parts.
- 3
OEM versus quality aftermarket decision. For hardware and weatherstrip, we default to PGT OEM. For glass replacement on out-of-warranty units, we specify equivalent laminated glass from our certified supplier with matching thickness, interlayer, and Miami-Dade NOA - documented on the written quote.
- 4
Installation with temporary bracing and documented setting. Custom and geometric units get braced until sealant cures. We photograph setting-block placement, shim locations, and final reveal before trim goes back.
- 5
Operational test and photo record delivery. Every moving part is cycled. The photo record uploads to your file by end of day. The invoice matches the original written quote - Haven Clause 1 and Clause 5.
- 6
365-Day Done Right Promise activation. The warranty document is dated and signed before we leave. If the reveal opens up or the sealant checks, we return and make it right - written into the Haven Standard, not offered as a courtesy.

AfterWhat PGT Custom & Geometric Windows Costs in Lantana
| Scenario | Typical Range |
|---|---|
| Single arched or radius top, Winguard Aluminum, impact-rated | $2,800 - $4,500 |
| Trapezoid or pentagon replacement, WinVue vinyl, standard glass | $1,900 - $3,200 |
| Oversized fixed geometric, Winguard Architectural, 72″+ dimension | $5,500 - $9,000 |
| Full-opening assembly with multiple custom shapes, impact-rated | $12,000 - $18,000+ |
| Glass-only replacement, laminated impact, custom cut | $800 - $2,400 |
What moves the price: radius complexity (true radius versus elliptical), impact rating versus non-impact, glass size and thickness, and whether the original frame can be preserved or requires full replacement. Lantana’s salt-air exposure within 1,500 feet of the Intracoastal or ocean often specifies upgraded hardware finish - noted on the survey, priced on the quote.

Why Lantana Homeowners Call Sightline Windows & Doors Lantana for PGT Work

We’ve logged work on homes from Hypoluxo Island to the Lantana Heights corridor - enough to know that a PGT Winguard unit facing the Atlantic fails differently than one on a west-facing inland elevation. Our crew leads carry license numbers, not just business cards, and every technician is background-checked under Haven Clause 3.
If PGT lead times stretch or a series discontinues, we specify equivalent performance from CGI, CWS, ES Windows, or ECO Window Systems - matched by U-factor, SHGC, and impact rating, not by what’s in the warehouse. The 365-Day Done Right Promise covers every installation. And the photo record you receive is the same documentation we keep - evidence, not marketing.
Measure it right the first time. Everything after that is just paperwork.
FAQs
No - if the repair uses PGT OEM parts and follows PGT’s published installation guidelines. We verify your unit’s warranty status by serial number before ordering parts, and we document OEM part numbers on every invoice. Using aftermarket glass or non-specified sealants will void coverage. Call (561) 461-2062 and we’ll check your warranty status at no charge during the free survey.
Standard custom shapes ship from PGT’s Venice, Florida facility in 4-6 weeks. Radius tops and oversized units run 8-10 weeks. We do not quote delivery dates we cannot verify - your written scope includes the expected ship week based on PGT’s current custom queue, updated if it slips. For urgent cases, we maintain relationships with CGI and CWS custom shops that can sometimes beat PGT’s timeline by two weeks on equivalent impact-rated units.
Repair makes sense when the frame is square, the thermal break is intact, and the failure is isolated to glass, hardware, or sealant. Replace when the frame has racked more than 1/4″ out of square, the thermal break is compromised at multiple corners, or the original unit predates 2010 and uses discontinued PGT profiles. We document both options with line-item pricing - no default to the more expensive choice.
Yes, with conditions. PGT maintains archival profiles for 15 years on most series. We send your unit’s serial number, field-verified dimensions, and a photo of the exterior finish to PGT’s custom shop for confirmation. If the original profile is discontinued, we specify the closest current PGT equivalent and note visible differences on the written quote before you approve. Lantana’s strict HOA requirements in communities like Lantana Heights mean we also verify exterior color match against association records when applicable.
Locate the PGT serial label - usually a white sticker on the hinge stile or head jamb - and photograph it. Note whether the issue is air infiltration, water intrusion, glass failure, or operation. Check if the problem is isolated to one unit or repeats across multiple windows on the same elevation. Bring us that information, plus any prior repair invoices, and we’ll diagnose during the free survey. Call (561) 461-2062 - a live person answers, 24/7.
