AfterCWS Custom & Geometric Windows in North Palm Beach: What to Know First
We provide independent CWS custom and geometric window service in North Palm Beach, with measured surveys that produce written quotes before any work begins and a documented photo record when the job is finished. Most CWS custom and geometric window repairs or replacements in our market run between $890 and $4,200 depending on whether we’re addressing seal failure in an existing shaped unit or installing a new impact-rated geometric opening. Turnaround from signed quote to installation typically ranges from 10 to 21 business days for standard CWS custom shapes, though oversized or curved units may extend to 35 days due to glass tempering schedules.
This page is for North Palm Beach homeowners who already own CWS windows and need custom or geometric work - arched transoms, circular or elliptical accent windows, trapezoid gable units, or oversized impact-rated shapes that standard replacements won’t fit. If the opening isn’t right, the window isn’t right - that’s where we start. Call (561) 475-1246 to schedule your free measured survey.
How CWS Products Fail - and How We Fix Them
- CWS 3120 Series fixed geometric units: We see fogging between panes in North Palm Beach homes built 2015-2019, especially on south-facing gable windows where the black spacer bar absorbs heat and degrades the primary seal. The 3120 uses a rigid thermal break that doesn’t flex with our afternoon thunderstorm temperature swings the way newer CWS lines do. We replace with a warm-edge spacer and silicone primary seal, not just a glass swap, because the frame will fail the next unit if we don’t address the expansion differential.
- CWS 5400 Series impact-rated custom shapes: Laminated glass delamination at the curved edge of radius-top units - the interlayer separates where the glass was heat-formed, creating a visible bubble that starts at the apex and works down. This is a manufacturing stress point, not impact damage, and CWS warranty coverage on it varies by original purchase date. We document the delamination pattern with frame readings before requesting parts, because CWS will reject a claim without photographic evidence of the defect’s origin point.
- CWS 4100 Series operable geometric casements: Hardware fatigue in trapezoid and pentagon configurations where the sash weight distributes unevenly across the hinge side. The operator arm on the 4100 was spec’d for rectangular loads; in a shaped unit, the bottom hinge carries 60% more torque. We upgrade to a heavy-duty Truth Encore operator with a custom-length arm, or specify a fixed geometric with a nearby operable rectangular companion unit if the opening geometry allows.
- CWS 6200 Series oversized custom rectangles: Sagging at the center rail on units over 72 inches wide, particularly in second-story installations where the header settlement was never fully corrected. The 6200’s aluminum stile is rated for the load, but North Palm Beach’s sandy substrate lets footings shift more than the CWS engineering tables assume for South Florida. We measure the diagonal racking before ordering, then specify a reinforced subframe or split the opening into a mulled pair depending on what the structure will bear.
- CWS 8100 Series coastal-grade geometric accents: Anodized finish chalking on east-facing eyebrow windows within three miles of the Intracoastal, where salt spray concentrates in the laminar flow off the water. The 8100’s anodizing is 25 microns, adequate for most of Florida but thin for direct marine exposure. We can source 50-micron anodized replacement frames through our ES Windows relationship, or specify CWS’s own coastal upgrade if the lead time works for the project schedule.
Our CWS Custom & Geometric Windows Process
- 1
Measured survey. Sonia Raman measures every opening herself on the first visit. We record rough opening dimensions, squareness, plumb, and header condition. You keep the survey document; it becomes the basis for the written quote.
- 2
Diagnostic and parts decision. We identify the CWS series, document the failure mode with frame readings and photos, and determine whether OEM CWS parts, quality aftermarket equivalents, or a cross-manufacturer solution best serves the opening. We note the parts lead time in writing before you sign.
- 3
Written quote. Haven Clause 1: the price we write is the price you pay. No change orders for conditions we could have measured. The quote specifies glass type, spacer, hardware, and finish. We also note if the CWS warranty on your unit is still active and whether we can assist with a claim.
- 4
Fabrication and staging. Custom and geometric CWS units ship from the Tampa facility or, for impact-rated shapes, from the Miami assembly plant. We verify the unit against our survey before scheduling installation.
- 5
Installation and testing. We install to CWS specifications where they meet or exceed code, and to our own tolerances where they don’t. Every unit is checked for operable sash balance, fixed sash seal compression, and impact-rated fastener torque where applicable.
- 6
Documentation and guarantee. You receive the photo record of the completed work, the written scope, and the 365-Day Done Right Promise stamped under the Haven Standard. If it’s not done right, we make it right.

AfterWhat CWS Custom & Geometric Windows Costs in North Palm Beach
These are the price ranges we write on CWS custom and geometric window jobs in North Palm Beach, based on 2024-2025 measured surveys:
| Scenario | Typical Range |
|---|---|
| CWS 3120 series - seal failure, standard geometric shape (circle, half-round, quarter-round) | $890 - $1,450 |
| CWS 4100 series - hardware replacement, operable trapezoid or pentagon casement | $1,200 - $1,850 |
| CWS 5400 series - laminated glass delamination, radius-top impact unit | $1,650 - $2,400 |

| CWS 8100 series - full frame replacement, coastal-grade anodized geometric accent | $2,800 - $4,200 |
What moves the price: whether the rough opening needs correction, whether the unit is impact-rated (laminated glass, heavier hardware, permit and inspection), and whether we can use CWS stock shapes or must specify a true custom form. Permit and inspection for impact-rated work in North Palm Beach adds $180-$320; we pull the permit and schedule the inspection, included in the written scope. Call (561) 475-1246 for your exact quote - estimates are free, and we offer a free second opinion on any written estimate you’ve already received.
Why North Palm Beach Homeowners Call Sightline Windows & Doors North Palm Beach for CWS Work
We are an independent CWS service provider - not affiliated with or authorized by CWS - which means we can source across eight manufacturer lines including PGT, CGI, ES Windows, and ECO Window Systems when a CWS unit isn’t the best fit for your opening or your timeline. Our technicians are background-checked, uniformed, and identified by license number before arrival; Haven Clause 3 means the person at your door is the person on the record. Calls are answered by a live person, 24/7.
The 365-Day Done Right Promise applies to every job, not as a courtesy but as a clause in the Haven Standard that has governed every one of the 18,000+ openings we’ve touched since 2012. In North Palm Beach, we’ve done retrofit work in Lakeside Park where older concrete-block homes needed full rough-opening corrections before a single new unit could go in. We know what a quarter-inch assumption costs in this soil, in this salt air, with these temperature swings. We don’t make them.
FAQs
Will repairing my CWS custom window void the manufacturer warranty?
It depends on the original purchase date and whether the repair addresses a defect CWS covers. We document the failure mode with frame readings and photos before touching the unit, and we can assist with a warranty claim if your unit qualifies. If the warranty has expired or the damage is outside CWS coverage, we quote the repair independently. Call (561) 475-1246 and we’ll review your situation at no charge.
How long do CWS custom geometric parts take to get?
Standard CWS geometric shapes from the Tampa facility typically ship in 7-12 business days. Impact-rated custom units from the Miami plant run 14-21 business days. True custom forms not in the CWS catalog - a specific radius, an unusual ellipse ratio - can extend to 35 days for glass tempering and IG fabrication. We state the lead time in writing on every quote so you can plan around it.
Should I repair my CWS geometric window or replace the whole unit?
Repair makes sense when the frame is sound and the failure is isolated to glass, seal, or hardware - typically 40-60% of the replacement cost. We recommend replacement when the frame has shifted with the structure, when the anodized finish has failed on a marine-exposure unit, or when you want to upgrade from non-impact to impact-rated. We give you both numbers on the same quote so you can decide.
Can you match a CWS geometric window if CWS no longer makes that shape?
Yes. We maintain cross-reference specifications to PGT, CGI, ES Windows, and ECO Window Systems geometric lines, and we’ve successfully matched discontinued CWS profiles using manufacturer-agnostic subframes. The match is verified by sightline measurement and glazing stop dimension, not by visual approximation. We show you the cross-reference documentation before you commit.
Do you pull permits for CWS impact-rated geometric window work in North Palm Beach?
Yes. Impact-rated window installation in Palm Beach County requires a permit and passing inspection. We pull the permit, schedule the inspection, and include both in the written scope. The permit fee runs $180-$320 depending on the number of openings; it’s listed as a line item on your quote, not buried in overhead. Call (561) 475-1246 to schedule your free measured survey.
