CWS Window Replacement: The Jupiter Owner’s Guide
CWS window replacement in Jupiter typically runs $340-$780 per opening installed, depending on the series, glass package, and whether the frame is salvageable. We stock CWS-compatible frames, sashes, and hardware for same-day replacement on most residential series, and we carry the full CWS catalog for special-order jobs. Most Jupiter homeowners discover the problem when a sash won’t stay open, water beads inside the glass, or the lock no longer draws the meeting rail tight against the weatherstrip.
Which CWS Models This Applies To
CWS built its Florida reputation on three residential lines you’re likely to find in Jupiter homes: the Aria series (vinyl impact-rated, common in 2016-2021 builds), the Estate series (aluminum impact with thermal break, frequent in Tequesta and Abacoa), and the Classic series (non-impact vinyl, often in original construction from the 2005-2015 window boom). The label is usually etched in the corner of the glass or stamped on the sill track; if it’s worn off, measure the visible glass width and height, the overall frame depth, and whether the meeting rail is interlocking or flat. That combination tells us the series and the replacement path.
We are an independent service provider, not affiliated with CWS. For most Jupiter jobs we source factory-original CWS sashes and frames; on discontinued series we match with ES Windows or PGT equivalents that meet the same Miami-Dade and HVHZ ratings. The aftermarket decision matters on Aria double-hungs from 2017-2019, where CWS changed the pivot-bar width from 5/16″ to 3/8″ mid-production. Order the wrong bar and the sash tilts out of the jamb. We measure on site before ordering, not after.
Signs Your CWS Window Replacement Is Failing

- Sash drops or won’t stay open. The coil balance or block-and-tackle system has lost tension. In Jupiter’s salt air, the galvanized spring housing corrodes faster than inland specs predict; we replace with stainless hardware on coastal jobs.
- Fog between the glass panes. The insulated glass unit (IGU) seal has failed. CWS IGUs from 2012-2018 used a dual-seal system that held well in dry climates but allowed edge migration in Florida’s 85%+ summer humidity; replacement requires the exact glass thickness and spacer color to match sightlines.
- Lock won’t draw the sash tight. The keep or cam has worn, or the frame has settled. On aluminum Estate series, we check for rail twist first; a twisted meeting rail eats locks and weatherstrip together.
- Visible water staining on the sill. Weep channels are blocked with sand and organic debris, or the sill track cap is cracked. Jupiter’s afternoon storms drive water hard; if the weep system can’t drain, the sub-sill rots.
- Frame corner separation or sealant failure. Vinyl expands roughly 1/8″ per 10 feet of frame in summer heat. CWS vinyl corners are fusion-welded, but the sealant bead at the frame-to-wall interface degrades; we cut out and re-bed with backer rod and OSI Quad Max, not generic caulk.

AfterReplacement Cost & What’s Included
| Component | Typical Range (Jupiter) |
|---|---|
| CWS IGU replacement (glass only, sash salvageable) | $340-$520 |
| Full sash replacement (CWS OEM, including balance hardware) | $480-$680 |
| Complete frame-out replacement (same size, impact-rated) | $620-$780 |
| Discontinued series, custom-matched equivalent | $560-$740 |
The range depends on three factors: whether the existing frame is square within 1/8″ (if not, we reframe), whether the job requires a ladder set over 20 feet (Jupiter’s two-story coastal homes often do), and whether the replacement must match a specific HOA color or grid pattern. Our quote includes the measured survey you keep, the written scope, the CWS or equivalent product, installation, sealant, trim touch-up, and disposal. The price on the page is the price on the invoice. Haven Clause 1.
Every replacement carries our 365-Day Done Right Promise. If the sash doesn’t operate smoothly, the lock doesn’t engage flush, or the weep system backs up, we return and correct it. The photo record from your job documents the condition before and after; you receive a copy.
DIY or Call Us?

An owner can safely check three things: whether the weep holes are clear (a pipe cleaner or compressed air, from outside), whether the lock keep is loose (a Phillips screwdriver, but stop if the screw spins), and whether the sash tilt latches engage fully. Beyond that, replacement work involves tempered glass, ladder access, and frame alignment to 1/16″ to maintain impact rating. CWS impact windows rely on a continuous frame-to-wall attachment pattern; miss a fastening schedule and the assembly fails under design pressure. We don’t recommend owner replacement on impact-rated units.
Measure once, quote it straight, install it right - that’s the whole business. If your CWS window is showing any of the symptoms above, call (772) 362-5402 to schedule your free estimate.

FAQs
IGU seals typically fail at 12-18 years in coastal Palm Beach County, sooner if the home is within a mile of the Intracoastal and sees direct salt spray. Frame and hardware often outlast the glass by a decade. Call (772) 362-5402 for an exact assessment of your units - estimates are free.
Fogged IGUs cannot be defogged permanently; the desiccant inside the spacer is saturated and the seal is broken. A drilled vent with a valve is a temporary cosmetic fix that voids any remaining warranty and drops the U-factor. We replace the IGU or full sash. Call (772) 362-5402 for a written quote on either option.
A single IGU or sash swap takes 90-120 minutes on site. A full frame-out replacement runs 3-4 hours per opening, including removal, reframing if needed, installation, sealant cure time, and cleanup. We schedule by the job, not by the hour, so the time doesn’t change your price. Call (772) 362-5402 to book.
We carry CWS-compatible balances, locks, keepers, and weep covers for same-day repair on Aria and Estate series. Full sashes and IGUs are ordered to measured size and typically arrive in 5-7 business days; we store them at our Jupiter warehouse and call to schedule installation the day they land. Call (772) 362-5402 to confirm availability for your series.
