AfterCWS Custom & Geometric Windows in West Palm Beach: What to Know First
We provide independent CWS custom and geometric window service in West Palm Beach, from arched impact units in El Cid to oversized geometric assemblies along Flagler Drive. Most CWS custom jobs run two to four weeks from measured survey to install, depending on glass tempering and profile availability. The price we write on the survey document is the price on the invoice - Haven Clause 1, no exceptions.
This page is for homeowners who already own CWS windows or are specifying them for a new custom opening and need a West Palm Beach installer who stocks the series, knows the failure patterns, and documents every step. Call (561) 354-3861 to schedule your free measured survey.
How CWS Products Fail - and How We Fix Them
- CWS 4120 Series impact casements: hinge-side frame fatigue in coastal exposures. The 4120’s extruded frame wall is thinner at the hinge jamb than competing PGT or CGI profiles. In West Palm Beach’s salt-air environment, we’ve tracked repeated stress cracking where the sash weight meets that thinner wall, especially on taller custom units. We sister the jamb with a CWS-compatible reinforcement extrusion and reset the sash to factory torque spec, not guesswork.
- CWS 5400 Series fixed geometric windows: seal decompression in south-facing gables. The 5400 uses a dual-durometer glazing wedge that stiffens in cold shipping but never fully recovers in South Florida heat. In Northwood and Flamingo Park jobs, we’ve found the wedge pulling away from the lite at the 2 o’clock and 10 o’clock positions on arched tops. We replace with a silicone-compatible setting block system that maintains compression across the temperature swing.
- CWS custom radius tops: glazing tape migration on retrofits. CWS ships radius units with a pre-applied glazing tape that flows under sustained heat if the installer doesn’t verify substrate temperature at time of application. We’ve peeled and re-glazed five of these in the past two years, always documenting the substrate reading with a photo the customer keeps.
- CWS 3120 Series single-hung custom sizes: balance shoe fracture in oversize sashes. When CWS stretches the 3120 beyond 42 inches wide, the coil balance housing sees load it wasn’t designed for. The symptom is a sash that holds at 12 inches open but drops below that. We spec a heavier-duty balance from the same OEM supplier CWS uses, not a generic, and we stamp the new load rating on the survey.
- CWS impact-laminated custom lites: edge delamination at exposed corners. CWS’s interlayer can wick moisture at exposed cutouts in geometric shapes where the standard rectangular lite has four protected edges. We’ve replaced three trapezoid units in the South End where the corner was field-notched after delivery. Our fix: factory-ordered notched lites with sealed edges, documented with the CWS order confirmation.
Our CWS Custom & Geometric Windows Process
- 1
Measured survey. Sonia Raman or a verified crew member arrives with a printed license number, measures the rough opening and the existing frame in three planes, and records sightline dimensions the customer keeps.
- 2
Series verification and diagnostics. We identify the CWS series from frame profile, spacer bar marking, or corner key detail, then note any failure pattern we’ve documented for that line.
- 3
Parts decision with written rationale. OEM CWS parts when available and warranted; quality aftermarket when the OEM part is obsolete or the improvement is measurable. We write the choice and the reason on the scope.
- 4
Install with photo record. Every step - substrate prep, fastener pattern, shimming, sealant backer rod - photographed and uploaded to the customer’s job file.
- 5
Operational test and documentation. Sash operation, lock engagement, water test where accessible, and a final photo set. The customer receives the survey, the scope, the photo link, and the 365-Day Done Right Promise in writing.

Why West Palm Beach Homeowners Call Sightline Windows & Doors West Palm Beach for CWS Work
We’ve installed and serviced CWS products in West Palm Beach since 2012, long enough to know which series extrusions changed in 2018 and which parts cross to current stock. When CWS lead times stretch, we can specify equivalent performance from PGT, CGI, ES Windows, or ECO Window Systems - always by U-factor and design pressure, never by what’s in the warehouse.
Every technician is background-checked, uniformed, and identified by license number before arrival - Haven Clause 3. The 365-Day Done Right Promise covers every job, and the photo record is standard, not an upsell. Calls are answered by a live person, 24/7.
FAQs
No. As an independent CWS service provider, we use OEM or equivalent parts and document the work so your product warranty remains intact. We keep CWS order confirmations and installation records on file for any future claim. Call (561) 354-3861 if you need a specific warranty question researched before we start.
Yes, for most series back to the early 2000s. We maintain cross-reference sheets for discontinued CWS hardware and have direct relationships with the same component suppliers CWS used originally. When an exact OEM part is unavailable, we specify the equivalent in writing with load ratings and finish codes.
Repair is viable when the frame is structurally sound and the failure is isolated to glass, seal, or hardware. Replacement makes sense when the frame has fatigue cracks, the custom shape is no longer available for partial rebuild, or the energy performance no longer meets current Florida code. We write both options with prices when both are possible.
Repairs typically finish in one visit. Full custom replacements require two to four weeks for CWS to fabricate, plus one day for install and seal. We don’t quote delivery dates we can’t verify - the written schedule comes from CWS’s confirmed ship date, not our hope.
No. Haven Clause 1 means the measured survey and the written quote are the same document. If we encounter concealed damage - rot in the rough opening, for example - we stop, photograph it, and write a revised scope before continuing. No change orders mid-stream.
