CWS Window Replacement: The Fort Lauderdale Owner’s Guide
CWS window replacement in Fort Lauderdale typically runs $340-$780 per opening for standard vinyl or aluminum units, with impact-rated CWS models landing between $890-$1,450 installed. We stock CWS-compatible frames, sashes, and hardware for same-day replacement on most series, and we carry the full CWS catalog for orders that need custom sizing. Most Fort Lauderdale owners discover a CWS window needs replacement when the sash won’t stay open, the frame weeps condensation between panes, or the locking hardware strips out after years of salt-air exposure along the Intracoastal corridor.
Which CWS Models This Applies To

CWS manufactures three residential lines you’ll find in Fort Lauderdale homes built between 2015 and 2025: the CWS 300 Series (single-hung vinyl, non-impact), the CWS 500 Series (impact-rated vinyl with reinforced frames), and the CWS 7000 Series (thermally broken aluminum impact). The model label is stamped on the top edge of the sash rail or inside the jamb liner; if the label’s faded, measure the visible glass dimensions and the frame depth, 2-5/8″ for vinyl, 3-1/4″ for aluminum impact.
Here’s where CWS compatibility gets specific: the 500 Series uses a proprietary interlock design that changed in 2019. Pre-2019 units carry a flat interlock; post-2019 units use a stepped profile for improved water management. We’ve seen Fort Lauderdale homeowners order a 2023 sash for a 2017 frame and discover the interlock won’t seat. The hardware spacing also shifted, 4-15/16″ center-to-center on pre-2019 locks, 5-3/16″ after. We verify this on every measured survey.
On OEM versus aftermarket: CWS sells replacement sashes and frames through their dealer network with a 20-year glass warranty. Quality aftermarket equivalents exist for hardware and weatherstrip, but we specify OEM for any structural component because the Miami-Dade Notice of Acceptance number, CWS carries NOA-14-0215.04 and NOA-19-0322.06, ties to the original manufacturing record. Mixing non-listed components voids that certification. Sightline Windows & Doors Fort Lauderdale is an independent service provider, not affiliated with CWS.
Before
AfterSigns Your CWS Window Replacement Is Failing
- Sash drops or won’t stay open. The balance system, typically a constant-force coil spring in CWS single-hungs, has lost tension. In Fort Lauderdale’s humidity, we’ve seen these corrode in 6-8 years instead of the 12-15 you’d expect inland. The sash becomes a safety hazard if it slams shut unexpectedly.
- Fog between glass panes. The insulated glass unit seal has failed. CWS units use a dual-seal system, but salt-air intrusion at the glazing edge breaks the butyl primary seal faster near the coast. The glass is done; it cannot be resealed to factory spec.
- Frame corner weeps water during storms. The sill dam or weep flap is clogged, or the frame joint sealant has degraded. CWS vinyl frames use a welded corner, but the weep channels are small and trap debris from Fort Lauderdale’s pollen-heavy springs.
- Lock hardware spins without catching. The zinc die-cast keeper has stripped threads or the cam has worn flat. CWS changed lock vendors in 2020; pre-2020 hardware has a coarser thread pitch that doesn’t interchange with current production.
- Visible daylight around the sash when closed. The pile weatherstrip has compressed or the bulb seal has torn. CWS uses a dual-fin pile on impact units that flattens to about 60% of original height after 7-9 years of daily operation.
Replacement Cost & What’s Included

| Component | Typical Range (Installed) | Notes |
|---|---|---|
| CWS 300 Series sash replacement | $340-$520 | Standard vinyl, non-impact |
| CWS 500 Series sash replacement | $580-$780 | Impact-rated vinyl |
| CWS 7000 Series full frame | $890-$1,450 | Thermally broken aluminum impact |
| IGU only (glass swap) | $280-$440 | When frame and hardware are sound |
| Hardware set (lock/keeper) | $85-$140 | OEM specified for NOA compliance |
What drives the range: frame condition, stucco repair extent, and whether the original installation used proper flashing. We find about 30% of Fort Lauderdale CWS replacements need sill pan correction because the original installer skipped the end dam seal. Our price includes the measured survey you keep, the written scope, permit pull if required, and the documented photo record. Every CWS replacement carries the 365-Day Done Right Promise under Haven Clause 5: No Surprises. The written price before any work starts is Haven Clause 1; the quote and the final invoice are the same document.
DIY or Call Us?
What you can safely check: verify the model label location, clear weep channels with a pipe cleaner, and confirm the lock engages fully. What goes wrong fast: removing a CWS impact sash without supporting the frame rails risks frame racking, and the constant-force balance stores enough energy to snap a finger if released wrong. We’ve been called to Fort Lauderdale homes where a homeowner cracked the IGU trying to force a sash tilted backward. The glass is tempered; when it goes, it goes everywhere.
Measure it right the first time or measure it twice on someone else’s dime. That’s why our measured survey happens before any unit is ordered. Call (754) 666-7478 to schedule yours. Estimates are free, and we also review competitor written estimates at no charge under our Free Second Opinion policy.
FAQs

Expect 15-20 years for vinyl frames and 20-25 for aluminum impact units, but salt-air exposure within two miles of the Intracoastal Waterway cuts that by 3-5 years if the exterior finish isn’t maintained. The IGU seal is usually the first failure point, 8-12 years in coastal zip codes. Call (754) 666-7478 and we’ll assess what your specific installation faces.
No. Once the IGU seal fails and moisture enters the air space, the desiccant inside the spacer bar saturates and the low-E coating begins to degrade. Defogging services drill vent holes that eliminate the insulating value and void any remaining warranty. Replacement with a new IGU is the only proper fix. Call (754) 666-7478 for an exact quote, estimates are free.
A standard sash swap takes 45-90 minutes per opening; a full-frame replacement runs 3-5 hours including interior and exterior trim work. We schedule one opening or the whole house, and we don’t leave until the documented photo record is complete. Call (754) 666-7478 to set a date that works.
We carry CWS-compatible balances, locks, keepers, and weatherstrip for the 300 and 500 Series on every Fort Lauderdale truck. Full sashes and frames are ordered to the measured survey, typically 10-14 business days for standard sizes, 4-6 weeks for custom geometry. If your hardware failure is urgent, we can often match function with a compatible interim part while the OEM order arrives. Call (754) 666-7478 to confirm what’s in stock for your series.
