CWS Custom & Geometric Windows in Kendall: What to Know First

We install and service CWS custom and geometric windows in Kendall as an independent CWS service provider, with most measured surveys scheduled within 48 hours and written prices delivered before any work begins. A typical CWS custom or arched window replacement in this market runs from $1,800 to $4,200 depending on the series, the shape complexity, and whether the opening requires impact-rated glazing. We do not quote over the phone; Haven Clause 1 requires that the measurement and the written price be the same document, and you keep the survey.

This page is for Kendall homeowners who already have CWS products and need custom shapes replaced, arched tops re-glazed, or oversized geometric openings upgraded to current impact standards. If you are comparing CWS against PGT, CGI, or ES Windows for a new installation, we specify by performance tier and price range, not by margin. Call (786) 321-3319 to schedule your measured survey.

How CWS Products Fail - and How We Fix Them

• CWS Aegis series: seal failure in arched tops. The thermal break in Aegis geometric units can separate at the radius point where the extrusion is stress-formed, not mitered. We see this in Kendall’s 33176 and 33186 ZIP codes where afternoon sun loads hit the southern exposure hard. Our fix: we source the OEM radius extrusion from CWS’s Miami distribution point, never force a flat-gasket solution into a curved jamb, and document the dry-fit with photos before sealant application.
• CWS WindPact impact geometric units: corner delamination in oversized triangles and trapezoids. The laminated interlayer in WindPact custom shapes can creep at the acute-angle corners when the unit exceeds 60 inches on any leg. This is a known assembly tension issue, not impact damage. We fix it by specifying a thicker interlayer, 1.52mm SGP rather than 0.76mm PVB, on replacement units over that threshold.
• CWS Casement custom shapes: operator arm binding in salt-air environments. The stainless operator arms on coastal Kendall installations corrode at the pivot where the factory grease washes out. We replace with Truth Hardware operators that have sealed bearing pivots, and we re-grease on a two-year cycle as documented maintenance.
• CWS Picture window geometric assemblies: sill pan deflection in openings over 96 inches wide. The CWS sill extrusion is rated for 72-inch spans without a mullion; beyond that, the dead-load of laminated glass causes the sill to belly. We sister a structural sub-sill of 6063-T6 aluminum, break-bonded to the frame, and document the load calculation in the photo record.
• CWS Fixed geometric units: argon loss in radius-top configurations. The single-point seal at the apex of a CWS radius top is the failure path; argon escapes and condensation follows. We do not “re-gas” units in the field. We replace with a dual-seal warm-edge spacer system, and we test with a gas-fill analyzer before the unit leaves our Kendall staging area.

Our CWS Custom & Geometric Windows Process

1. 1
   Measured survey you keep. Sonia Raman or a verified crew member arrives with a printed license number, measures the opening to 1/16 inch, notes the existing CWS series marking on the frame edge, and records the sightline dimensions. You receive this document before we leave.
2. 2
   Diagnosis and parts decision. We identify whether your CWS unit is a current series or legacy line. If CWS has discontinued the extrusion, we source quality aftermarket that matches the thermal and structural spec, or we cross-reference to PGT or CGI equivalents if a full replacement makes sense.
3. 3
   Written scope and price. The quote references the survey document by date and job number. The price is fixed. No change orders. This is Haven Clause 1.
4. 4
   Fabrication and staging. Custom CWS geometric units typically fabricate in 4 to 6 weeks. We stage at our Kendall facility, inspect for glass defects and frame straightness, and photograph the unit before delivery.
5. 5
   Installation and dry-fit. We set the frame without sealant first, check plumb and level, then document the fit with photos. Only then do we apply sealant and secure. Measure once, document it, then cut.
6. 6
   Final test and photo record. We operate the unit, check for air infiltration with a smoke pencil, and deliver the documented photo record to you within 24 hours. The 365-Day Done Right Promise begins at this point.

What CWS Custom & Geometric Windows Costs in Kendall

What moves the price: impact-rated versus non-impact glazing, the number of mullions required, whether the stucco return needs repair after frame extraction, and whether we are matching existing CWS grid patterns that have been discontinued. We do not estimate these variables over the phone; the measured survey determines them.

Why Kendall Homeowners Call Sightline Windows & Doors Kendall for CWS Work

We are independently owned and operated under the Haven Standard, not a franchise, and we have measured and set frames in Kendall since 2012. Sonia Raman’s crew most recently finished a full impact-window retrofit on a block of townhomes near Dadeland Mall, including four CWS custom arched units that required radius extrusions no longer in active production.

Our technicians are background-checked, uniformed, and identified by license number before arrival. We carry eight manufacturer lines - PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux - so if your CWS series is discontinued or ill-suited to your opening, we specify by what the opening requires, not by what is in stock. The 365-Day Done Right Promise is stamped on every job, not offered as a courtesy. Calls are answered by a live person, 24/7.
