CWS Windows & Doors Nationwide

CWS Windows & Doors: The Boca Raton Owner’s Guide

We stock and install CWS-compatible windows and doors across Boca Raton, with most replacement parts available same-day and full unit replacements quoted at $4,500-$15,000 for window replacement or $8,000-$25,000 for impact window installation depending on series and opening count. Most Boca Raton owners discover a CWS part has failed when they feel salt air drafts around the sash, see condensation between panes after a summer storm, or find the lock mechanism grinding instead of latching tight. In coastal zip codes like 33432 and 33431, we’ve learned to check for frame swelling and hardware corrosion first, because the part that looks broken often isn’t the part that caused the failure.

Which CWS Models This Applies To

CWS Window Systems builds several product lines that circulate in Boca Raton’s 2005-2025 housing stock, and the part you need depends on which series is installed. The CWS 3120 single-hung and 3150 double-hung vinyl windows use a specific tilt-latch and balance shoe geometry that differs from the CWS 5400 casement series by about 3/16 inch in pivot bar width. The CWS impact-rated 9000 series, common in post-2017 construction near the Intracoastal, carries heavier laminated glass and correspondingly larger hinge assemblies that won’t retrofit onto standard frames.

To identify your part, look for the etched CWS logo in the glass corner and a paper label inside the frame head or sill track with a six-digit model prefix. We carry OEM CWS balances, tilt latches, and weatherstripping, plus quality aftermarket equivalents from Truth Hardware and Amesbury that match the spec at lower cost when the original part is back-ordered. One compatibility gotcha we’ve hit repeatedly in Boca Raton: the 3120 series made before 2012 used a coil balance with a 5/8-inch drum diameter, while post-2012 production switched to 3/4 inch. The two are not interchangeable, and forcing the wrong balance destroys the jamb liner in about six months of Florida heat cycling.

Signs Your CWS Windows & Doors Is Failing

• The sash won’t stay open or slams shut. This usually means the coil balance has lost tension or the balance shoe has cracked. In Boca Raton’s humidity, the nylon shoe degrades faster than the manufacturer rates it, and we’ve replaced balances in CWS units as young as eight years old that were spec’d for fifteen.
• Condensation between the glass panes. The insulated glass unit (IGU) seal has failed, allowing moist Gulf Stream air inside. Once the desiccant saturates, the fogging becomes permanent and the low-E coating starts deteriorating at the edge. We measure the daylight opening and order a replacement IGU to the exact 1/8-inch dimension rather than replacing the whole sash.
• Locking mechanism sticks or won’t engage. Salt air corrodes the zinc die-cast keepers and cams, especially on east-facing units within a mile of the Atlantic. The lock often fails secondarily, after the sash has sagged due to worn hinges or balances, so replacing only the lock without checking frame square wastes the repair.
• Visible daylight or drafts around the frame perimeter. The compression weatherstripping has flattened or the sill track has warped from UV exposure. In Boca Raton, south and west exposures see this first, sometimes in as little as six years on non-impact vinyl units.
• Cracking or chalking on the exterior frame surface. Titanium dioxide degradation in the vinyl capstock, accelerated by the combination of intense UV and salt spray. This is cosmetic until it reaches the substrate, but it signals the unit is approaching the end of reliable service life.

Replacement Cost & What’s Included

For CWS window replacement in Boca Raton, our installed pricing runs $4,500-$15,000 for standard window replacement and $8,000-$25,000 for impact-rated installation, with the spread driven by opening count, series selection, and whether the existing frame is preserved or fully replaced. A single CWS sash balance replacement, including parts and labor, typically falls between $180 and $340. IGU replacement in an existing sash runs $280-$520 depending on glass thickness and low-E specification. Hardware-only swaps, locks and keepers, are usually $95-$175 installed.

Every quote we write itemizes parts, labor, and disposal separately, and we deliver that number before any work starts, every time. Under Clause 1 of the Haven Standard, the price you sign is the price you pay, no change order required unless you add scope. Our workmanship on parts replacement carries a 365-Day Done Right Promise, and full unit installations include the manufacturer’s glass breakage coverage plus our installation warranty.

DIY or Call Us?

There’s a safe middle ground for CWS owners. You can inspect the label location, photograph the failed part, and check the sash for obvious cracks or corrosion without risk. What we don’t recommend: attempting to replace a coil balance or remove an impact-rated sash yourself. The balance is under significant tension, and the wrong tool slip can send hardware into the glass or your hand. Impact glass units weigh 40-60 pounds per sash and require two people with proper suction lifts.

We’ve also seen homeowners order what looked like the right part online, then discover the 5/8-inch versus 3/4-inch balance drum issue or a superseded lock keeper profile. The return shipping and second trip usually cost more than having us match it correctly the first time. If you’re unsure which CWS series you have, call us at (754) 254-8065 and we’ll walk you through the identification over the phone, no charge. Measure twice, document everything, then build.
