CWS Window Replacement: The Davie Owner’s Guide
CWS window replacement in Davie typically runs $340 to $890 per opening installed, depending on whether the job is a sash-and-track swap or a full-frame replacement. We stock CWS-compatible hardware, glazing beads, and sash assemblies for same-day repair on most series, and we carry full replacement units for the 4000, 5000, and 8000 impact lines in our Davie warehouse. Most homeowners in Davie discover a CWS window part has failed when the sash won’t stay up on its own, the locking mechanism grinds instead of catching, or they notice daylight between the frame and sash after a storm season.
Which CWS Models This Applies To
CWS manufactures several distinct product tiers, and the replacement approach differs materially between them. The 4000 series non-impact vinyl window uses a lighter-duty balance system and snap-in glazing bead; the 5000 and 8000 impact-rated lines use reinforced frames, heavier laminated glass, and a completely different sash retention clip. We also service the CWS 6000 aluminum line found in some Davie townhome builds from 2016 to 2020.
To identify your exact model, check the spacer bar between the glass panes for a stamped CWS logo and series number, or look for the manufacturer’s sticker in the head jamb, usually on the operator side. The critical measurement is the daylight opening: the clear glass width and height, not the frame outside dimension. A 3050 CWS unit measures 36 inches by 60 inches in daylight opening; ordering by rough opening instead is the most common compatibility error we correct in Davie.
We are an independent service provider, not affiliated with CWS. For most repairs, we use OEM-spec CWS parts sourced through verified distribution channels. In some cases, a quality aftermarket equivalent meets the original spec at lower cost; we note this in writing on the quote and explain the difference. The 8000 series impact lock, for instance, has a single aftermarket source that matches the zinc-alloy composition; the 4000 series balance shoe has several, and we default to OEM only because the channel-width tolerance is tighter.
Signs Your CWS Window Replacement Is Failing

- The sash drops or won’t stay open. This points to a failed coil balance or broken balance shoe in the jamb liner. In Davie’s humidity, the nylon balance shoes in pre-2019 CWS 4000 series units tend to crack after seven to ten years, especially on south-facing elevations where heat cycling accelerates the degradation.
- Visible moisture between glass panes. The insulated glass unit (IGU) seal has failed. CWS units from the 2015 to 2018 production window used a dual-seal system that held up well in Florida’s salt air, but we’ve replaced failed IGUs in Pine Island Ridge homes where the original sealant degraded faster on west-facing walls.
- Lock mechanism turns but doesn’t engage the keeper. The cam lock has worn or the keeper has shifted. On CWS impact units, the keeper is mounted through a reinforced strike plate; if the plate itself has cracked from overtightening or frame flex, the repair requires more than just a new lock.
- Air infiltration at the sash perimeter. The weatherstrip has compressed or the glazing bead has pulled away. CWS uses a flexible vinyl glazing bead that can shrink in sustained heat; we’ve measured gaps up to 3/16 inch on older Davie installations where the bead was never reseated after a glass replacement.
- Frame corner separation or visible bowing. The window frame itself is failing, usually from structural settling or impact stress. This is beyond part-level repair and requires full-frame replacement, which we confirm with a plumb and level reading during our measured survey.

AfterReplacement Cost & What’s Included
For Davie homeowners, CWS window replacement pricing breaks down as follows:
| Service Level | Typical Range | What’s Included |
|---|---|---|
| Sash/balance hardware repair | $340 - $520 | OEM or spec-matched part, labor, adjustment, photo record |
| IGU (glass-only) replacement | $480 - $720 | Measured IGU, low-E coating match, argon fill, installation, 365-Day Done Right Promise |
| Full sash replacement | $620 - $890 | Complete sash assembly, hardware transfer or new, alignment, operation test |
| Full-frame replacement | $1,400 - $2,800 | Removal, new CWS unit, flashing, trim, permit if required, final inspection documentation |
What moves the price: the series (impact-rated 8000 units cost more than 4000 vinyl), the glazing specification (tempered, laminated, or impact), and whether the opening requires structural repair. Every quote we write in Davie is based on the measured survey the customer keeps; the written scope and the final invoice are the same document. Haven Clause 1. No change orders unless the customer requests additional work in writing.
The 365-Day Done Right Promise covers all replacement work. If the sash doesn’t operate smoothly, the lock doesn’t seat flush, or the weatherstrip shows compression gaps within a year, we return and correct it. The promise is written into the Haven Standard, not offered as a courtesy.
DIY or Call Us?

There is one thing a CWS owner can safely check: remove the sash and inspect the balance shoe for visible cracking, or run a dollar bill around the closed sash to test seal compression. Beyond that, replacement parts require precise measurement and proper tooling. A coil balance under tension can release suddenly; laminated glass in an impact unit is heavy and requires two trained handlers; and an improperly seated IGU will fail again within months.
We do not recommend DIY replacement of CWS impact hardware or glass units. The warranty on the part is void if installation deviates from manufacturer spec, and the safety risk is real. Our technicians are background-checked, uniformed, and identified by license number before arrival, per Haven Clause 3. Call (754) 254-8492 to schedule your free estimate. We’ll measure the opening, identify the exact series and part, and give you a written price before any work starts.
FAQs
How long should a CWS window part last in Davie’s climate?
Hardware components in CWS 4000 and 5000 series units typically last 10 to 15 years in Davie’s subtropical conditions, though south- and west-facing elevations may see balance shoe or weatherstrip degradation closer to 7 years due to UV exposure and heat cycling. Impact-rated 8000 series hardware generally lasts longer because the frame construction reduces flex stress on the moving parts. Call (754) 254-8492 for an exact quote on replacement - estimates are free.
Can the part be repaired instead of replaced?
Some CWS components can be adjusted or reseated: a misaligned keeper, a balance shoe that has slipped its track, or glazing bead that has pulled loose. But once a coil balance has lost tension, an IGU seal has failed, or a lock cam has worn its detent, repair is temporary at best and the part should be replaced. We note in writing whether your issue is adjustable or requires new components. Call (754) 254-8492 for an exact quote - estimates are free.
How long does a CWS window replacement take?
A hardware or balance replacement on a standard double-hung takes 45 to 90 minutes per opening. An IGU replacement requires two visits: one to measure and order the exact glass specification, then a return visit of about an hour per unit to install and seal. Full-frame replacement is typically a full day for three to five openings, including removal, installation, and trim work. Call (754) 254-8492 to schedule - estimates are free.
Do you stock CWS parts in Davie?
We stock CWS-compatible balances, locks, keepers, and glazing bead for the 4000, 5000, and 8000 series in our Davie warehouse, along with common sash assemblies for same-day repair. Less common parts or custom sizes require one to three business days to source through verified distribution. We confirm availability during the measured survey and note it on the written quote. Call (754) 254-8492 for an exact quote - estimates are free.
