CWS Custom & Geometric Windows in Boca Raton: What to Know First
We install and service CWS custom and geometric windows in Boca Raton as an independent CWS service provider - not a factory-authorized dealer, but a shop that stocks CWS hardware and has measured enough of these units to know where the tolerances tighten. Most CWS custom jobs in Boca Raton run three to five weeks from measured survey to installation, with the written price fixed before we order glass. If you’re looking for a quote that shifts after work starts, we are not the right fit.
This page is for homeowners who already own CWS products or are specifying them for new construction or renovation in Boca Raton, including the coastal zones where impact-rated custom shapes are required by code. Call (561) 200-8592 to schedule a measured survey. We will bring the written price to that first visit.
How CWS Products Fail - and How We Fix Them
- CWS Aegis series impact-rated geometric windows: The corner keys in trapezoid and pentagon configurations loosen under the expansion cycles of Boca Raton’s afternoon heat and overnight humidity shifts. We see this in west-facing gables from Spanish River Land to Boca West. Our fix is a full corner key replacement with marine-grade fasteners, not shims, and we reseal with Dow 795 to match the original glazing spec.
- CWS WindPact Plus arched tops: The curved sash on these units carries stress at the springline where the arch meets the jamb, and after five to seven years the thermal break separates at that point. We replace the sash rather than attempt a field repair, because a patched thermal break in an arched unit will fail again within two seasons.
- CWS custom oversized fixed glass: Units over 60 by 96 inches in CWS’s custom line rely on a heavier deadload shoe that we have found cracks under sustained load if the rough opening is out of plumb by more than 1/8 inch. We measure plumb before we quote, and if the opening is off, we price the reframing into the written scope so there is no change order later.
- CWS geometric casement operators: The roto gear in CWS’s custom casement line strips when homeowners force a unit that has settled slightly in its frame. We stock the OEM roto assembly and the aftermarket alternative; we will show you both and explain the warranty implications of each before we install either.
- CWS coastal anodized finish on custom shapes: The anodized layer on CWS bronze and black custom units chalks faster in Boca Raton’s salt air than the manufacturer’s inland spec sheets suggest, particularly within a mile of the Intracoastal. We document finish condition during our survey and note whether a factory recoat, a field-applied fluoropolymer touch-up, or full replacement is the honest recommendation.
Our CWS Custom & Geometric Windows Process

- 1
Measured survey you keep. Sonia Raman or a verified crew member arrives with a laser measure, level, and the CWS sizing manual. You receive a copy of every dimension, rough opening condition, and finish note.
- 2
Written scope and price. Haven Clause 1: the quote is the same document as the survey, with line-item pricing for glass package, hardware, labor, and any reframing. No verbal estimates. No “we will see once we start.”
- 3
Parts decision with documentation. For CWS units still under factory warranty, we source OEM parts when the lead time is reasonable. For out-of-warranty work, we may recommend a quality aftermarket equivalent and note the difference in writing.
- 4
Installation with photo record. Verified crews install per CWS’s fastening pattern for impact-rated custom shapes, which differs from standard rectangular units. We photograph every stage: rough opening, shimming, fastener placement, and final seal.
- 5
Operational test and sign-off. Every moving sash is cycled twenty times. Every fixed unit gets a light test for seal integrity. You sign the completion document; we file the photo record.
- 6
365-Day Done Right Promise activation. The Haven Standard warranty is stamped on your paperwork, not offered as a courtesy. If it is not done right, we make it right.

Why Boca Raton Homeowners Call Sightline Windows & Doors Boca Raton for CWS Work

We are not a single-brand shop. If your CWS custom unit is back-ordered or discontinued, we can cross-reference to PGT, CGI, ES Windows, or ECO Window Systems and specify a replacement that fits the same rough opening without reframing. Our crews are background-checked and uniformed under Haven Clause 3, with license numbers provided before arrival. Every job since 2012 has left a documented photo record, and every quote has matched the final invoice. The 365-Day Done Right Promise is written into the Haven Standard, not a verbal assurance we might remember differently later.
Sonia Raman learned the glazing trade at Los Angeles Trade-Technical College and has spent the better part of two decades measuring and hanging windows across South Florida, including impact-rated sliding door replacements in the Broken Sound neighborhood. She keeps a running log of every unit: brand, glass package, U-factor, date, and customer name. A warranty conversation five years out goes better when you have the paperwork.
FAQs
No, factory warranties on CWS products cover defects in materials and workmanship regardless of who performs the installation, provided the work follows CWS’s published installation instructions. We document our compliance with those instructions in the photo record you receive. For warranty claims still within the factory period, we use OEM parts and note the part numbers in writing. Call (561) 200-8592 if you need help determining whether your unit is still under factory coverage.
CWS custom geometric glass typically ships in three to four weeks from order, with arched and oversized units sometimes stretching to five weeks during peak season. We do not quote installation dates until the glass is in our warehouse, because promising a date on an unconfirmed factory lead time is how other contractors create “supply chain” change orders. Call (561) 200-8592 to check current CWS lead times for your specific shape.
It depends on the crack location and the glass package. A surface crack in the exterior lite of an insulated laminated unit can sometimes be addressed with a sash replacement, preserving the frame and hardware. A crack that breaches the laminate layer or extends into the sightline of a geometric shape usually requires full sash replacement, because the structural integrity of the impact rating is compromised. We test with a polarized light and show you the result before recommending either path. Call (561) 200-8592 for a free assessment.
We stock the most common CWS hardware - roto operators, corner keys, deadload shoes, and standard weatherstrip profiles - in our Boca Raton warehouse. Custom extrusions and glass must be ordered to the measured survey. If we can fix your unit with stocked parts, we will; if the lead time for a custom part exceeds what makes sense for your situation, we will tell you that directly and discuss alternatives. Call (561) 200-8592 to describe your issue and we will confirm parts availability.
It does not. Haven Clause 1 of the Haven Standard states that the written price before work starts is the final price. The only exception is if you change the scope - upgrading glass package, adding units, or requesting a finish not in the original quote. Even then, we stop work, document the change in writing, and obtain your signature before proceeding. No surprises. Call (561) 200-8592 to schedule your free estimate.
