AfterCWS Custom & Geometric Windows in West Park: What to Know First
We provide independent CWS custom and geometric window service in West Park, typically measuring and quoting within 48 hours of your call, with most custom CWS installations scheduled within two to three weeks of approval. Our written price, delivered after a measured survey you keep, is the price on the final invoice - Haven Clause 1, no exceptions. This page is for West Park homeowners who own a CWS product and need arched, curved, geometric, or oversized custom windows repaired or replaced by technicians who know the line. Call (786) 685-4706 to schedule your free estimate.
How CWS Products Fail - and How We Fix Them
- CWS Custom Series fixed geometric units with segmented arch tops develop seal failures at the mullion joints where the straight leg meets the radius. We’ve traced this to thermal cycling stress on the dual-seal spacer in South Florida’s high-humidity environment, particularly in West Park homes without consistent HVAC. We remove the sash, inspect the spacer for corrosion, and replace with a warm-edge spacer and new dual-seal silicone - not a surface patch.
- CWS impact-rated custom shapes in the Aegis line show laminate de-lamination at the curved edges of quarter-round and half-round configurations. The PVB interlayer separates when the original glazing bed was set too thin for the radius stress. We re-glaze with OEM-spec laminate thickness and a heavier glazing bed, documented with pre- and post-installation photos.
- Oversized CWS custom openings (single units over 60 inches in either dimension) sag at the header over time, causing the sash to bind. In West Park, we see this on 1980s-era additions near Park Road where the original rough opening wasn’t engineered for the weight of modern impact glass. We install a reinforced sub-frame and re-square the opening, not just trim the sash.
- CWS geometric windows with applied SDLs (simulated divided lites) lose adhesion between the exterior SDL bar and the glass surface. The aluminum SDL profile expands at a different rate than the glass in direct sun. We remove the failed bars, clean the glass surface with specified solvent, and re-apply with OEM-compatible VHB tape rated for the exposure.
- CWS custom radius windows with integral jamb liners accumulate moisture in the track channel, corroding the balance system. The weep slots clog with coastal salt and pollen common to West Park’s inland-but-close proximity. We clear the drainage path, treat corroded balances, and replace with stainless hardware - or recommend a full sash replacement if the corrosion has reached the jamb box.
Our CWS Custom & Geometric Windows Process
- 1
Measured survey. We arrive with the CWS spec sheets for your series, measure rough opening, sightline, and square - you keep the document.
- 2
Diagnostics. We identify the failure mode: seal, glazing, frame, or hardware. If it’s a geometric or custom shape, we verify radius, chord, and rise against CWS manufacturing tolerances.
- 3
Parts decision. OEM CWS parts when available and warranted; quality aftermarket when OEM lead times exceed six weeks or the part is discontinued. We document the choice in writing.
- 4
Written quote. Same document as the measured survey, with line-item pricing. No change orders permitted under Haven Clause 5.
- 5
Installation. Background-checked, uniformed technician, license number provided before arrival. Photo record at rough opening, during, and completion.
- 6
Testing and documentation. Operate sash, check drainage, verify lock engagement. You receive the photo record and the 365-Day Done Right Promise stamped in writing.

Price moves with glass type (annealed, laminated, or impact-rated), radius complexity, and whether the original frame is salvageable. We do not quote over the phone for custom geometry - the chord and rise must be field-verified. Call (786) 685-4706 for your free estimate; the written price arrives within 24 hours of measurement.
Why West Park Homeowners Call Sightline Windows & Doors West Park for CWS Work
We’ve worked the residential streets near Sunview Park long enough to know which West Park homes still carry original single-pane aluminum frames from the 1980s and which have been retrofitted once already. Sonia Raman reads a rough opening correctly the first time, and our crew has handled CWS, PGT, CGI, ES Windows, and ECO Window Systems across enough jobs to know when a CWS part is the right specification and when another manufacturer’s geometry fits the opening better. The 365-Day Done Right Promise applies to every job. Live phone coverage at (786) 685-4706, 24/7. Measure it right, say what it costs, do the work.
FAQs
No - if the repair uses OEM-specified parts and procedures. As an independent CWS service provider, we document every part number and installation method so your warranty remains intact. We do not perform modifications that CWS would classify as field-altered. Call (786) 685-4706 if you need us to review your warranty documents before work begins.
OEM CWS custom geometric glass typically ships in four to six weeks from order confirmation. For radius or arched units with impact-rated laminate, we verify the template with CWS before cutting to avoid a remake. We keep you updated on lead time at quote and again at order - no surprises, per Haven Clause 5.
Usually, yes. We record the CWS series, glass tint, grid pattern, and SDL profile during our measured survey. If CWS has discontinued that exact configuration, we identify the closest current equivalent and show you the sample before ordering. The photo record from your original installation helps us match sightline and reveal.
Repair when the frame is square and the failure is isolated to seal, glazing, or hardware. Replace when the frame has sagged, the corrosion has reached the jamb box, or the custom shape is no longer available and the mismatch would be visible from the exterior. We tell you which category you’re in at the measured survey, not after work starts.
Both. CWS produces custom and geometric windows in impact and non-impact configurations. We specify by what your opening requires - if you’re outside the High-Velocity Hurricane Zone or your local amendment doesn’t mandate impact, we don’t sell you what you don’t need. Our eight manufacturer lines let us source the right product, not the one in stock.
