CWS Window Replacement: The Wellington Owner’s Guide

Replacing a CWS window in Wellington typically runs between $850 and $1,400 installed, depending on the series and whether the sash, glass unit, or full frame needs to come out. We stock CWS-compatible replacement sashes and hardware on our trucks and can complete most single-unit replacements in one visit. Most owners call us after they’ve felt a draft around the meeting rail on a humid afternoon, or noticed the latches no longer catch square when the frame has shifted.

Key Takeaways:

• CWS windows are regional to Florida’s impact-rated market; the parts are specific, and a generic sash from a supply house will not seat correctly.
• We identify your series by the corner-balance stamp and the number etched on the spacer bar, then quote OEM and quality aftermarket side by side.
• Both manufacturer warranty layers are registered in writing before our truck leaves your driveway.

Which CWS Models This Applies To

Most CWS units we service in Wellington fall into three families: the single-hung impact series, the horizontal roller series, and the fixed/lite picture units often paired with operable companions. The part you need depends on which has failed. On single-hungs, it is usually the spiral balancer or the tilt-latch shoe at the bottom of the sash. On horizontal rollers, the tandem roller assembly binds after years of fine Wellington sand working into the track. On fixed units, it is almost always the seal failing on the glass pack itself.

Here is the gotcha we see on CWS specifically: the sash profile is not interchangeable across series. A sash from the impact single-hung will not fit the non-impact version of the same nominal size, because CWS changes the frame depth to accommodate the heavier laminated glass. If you measure only height and width, you’ll order the wrong part. We match by the size, the frame profile depth, and the series stamp. For most homeowners, a quality aftermarket equivalent from a Florida-rated manufacturer performs as well as the OEM part at about 15 to 20 percent less, and we put both options on paper so you decide with full information.

Signs Your CWS Window Replacement Is Failing

• The sash drops when you raise it halfway. The spiral balancer has lost tension or the tilt-latch shoe has snapped. On CWS single-hungs, this usually shows up first in peak summer humidity when the channel swells.
• The window rolls hard or sounds like it’s dragging gravel. Wellington’s fine, sandy soil gets into the roller track and grinds down the nylon wheel until the assembly rides on the steel hub. You’ll hear it long before it stops rolling.
• Condensation between the panes. The glazing seal has failed. Florida sun and humidity are rough on spacer bars, and once moisture gets in, the glass pack cannot be cleaned. It gets replaced, not repaired.
• The locking lever won’t seat without forced effort. The frame has settled or the keeper has worn, and when you force the lock on an impact-rated CWS, you’re stressing the weld at the sash corner. That weld is the first place a forced sash fails.
• Rust bleed from the corner of the roller track. The stainless track screws have pulled through the end caps, letting the roller assembly pivot and scrape the aluminum. We see this most often on western-facing elevations that take afternoon sun.

Replacement Cost & What’s Included

Here is where Wellington pricing lands for CWS window replacement, installed:

• Glass pack replacement (failed seal or cracked lite): $280 to $520
• Balancer and tilt-latch shoe replacement (single-hung): $180 to $320
• Roller assembly replacement (horizontal roller): $220 to $390
• Full sash replacement, impact-rated CWS-compatible: $650 to $1,100
• Complete window replacement (sash and frame): $850 to $1,400

Every quote is parts plus labor, itemized in writing before any work begins. There are no surprise line items at the end. The workmanship is covered under the Done Right Promise, and we register both manufacturer warranty layers in writing before we pull the truck away. If the pane is not true, the job is not done.

DIY or Call Us?

One honest paragraph before you pick up a screwdriver: CWS impact-rated windows carry heavy laminated glass inside a balanced, tensioned sash. If you decompress a spiral balancer without the right retention tool, it releases with enough force to cut to the bone. The same goes for a loaded tilt-latch shoe. We do not recommend a homeowner take apart an impact sash. What you can safely do is clean the track, inspect the visible roller ends for wear, check that all lock screws are snug, and take a photo of the spacer-bar etching for us so we arrive with the right part. If the track is clear and the window still struggles, call (561) 349-4826. We’ll diagnose it on site, show you the part that failed, and quote the fix before we touch anything.
