AfterCWS Window Installation: The Davie Owner’s Guide
CWS window installation in Davie typically runs $340-$780 per opening for standard vinyl and aluminum replacement units, with impact-rated CWS systems landing between $890-$1,450 installed. We stock CWS frame components, sash hardware, and glazing beads on our Davie trucks, and most CWS part replacements or full-unit swaps are completed in a single visit. Homeowners usually discover a problem when the sash won’t stay open, they feel draft around the meeting rail, or they spot moisture between the glass lites after a Florida storm season.
Which CWS Models This Applies To
CWS produces three residential lines you’ll find across Davie: the WindPact Plus impact-rated vinyl series, the Aluminum Series 1000/2000 non-impact frames common in Pine Island Ridge homes built 2005-2015, and the Custom Vinyl line with integrated nail fins for new construction. The critical compatibility gotcha: WindPact Plus sashes from 2016-2019 used a proprietary interlock profile that differs by 3/16 inch from post-2020 production. If your CWS label (inside the head jamb or on the sash corner) shows a date code starting with 16-19, call us before ordering replacement sashes or the meeting rail won’t seal.
We carry both OEM CWS hardware and quality aftermarket equivalents from Truth and Caldwell. For the Aluminum Series 1000, we typically recommend OEM balances and keepers; the aftermarket versions fit but wear faster in Davie’s salt-air corridor within three to four years versus seven to ten for CWS factory parts. For glazing beads and weatherstripping, aftermarket EPDM equivalents perform identically at roughly half the part cost.
Signs Your CWS Window Installation Is Failing
- Sash drops or won’t stay open. The coil balance system has lost tension. In CWS vinyl units, this is usually a broken balance shoe or a rusted pivot bar after Florida humidity cycles. The sash becomes a safety hazard if it slams shut unexpectedly.
- Visible moisture or fog between glass panes. The insulated glass unit (IGU) seal has failed. CWS IGUs use a dual-seal system; once the primary PIB seal degrades from Davie’s UV exposure, argon escapes and condensation follows. This cannot be repaired; the IGU needs replacement.
- Draft at the meeting rail or frame perimeter. Compression weatherstripping has flattened or the sill track has bowed from thermal expansion. We measure the gap with a feeler gauge; anything over 0.125 inch at the meeting rail means air and water are getting through.
- Difficulty locking or unlocking. The sash has shifted in the frame, or the multipoint lock mechanism has corroded. CWS multipoint hardware from 2012-2017 used a zinc alloy that pitts in coastal Davie; we replace with stainless-steel equivalents.
- Frame corner separation or visible cracks. Vinyl profiles expand and contract roughly 0.004 inches per degree Fahrenheit. After a decade of Davie temperature swings, welded corners can stress-crack, especially on south-facing elevations. Full-frame replacement is usually the sound repair.

AfterReplacement Cost & What’s Included
| Service | Typical Range in Davie |
|---|---|
| CWS balance/keeper hardware replacement (per sash) | $180-$290 |
| CWS IGU replacement (per lite, standard size) | $340-$520 |
| CWS sash pack replacement (retrofit, per opening) | $580-$890 |
| CWS full-frame replacement, standard vinyl | $890-$1,250 |
| CWS full-frame replacement, impact-rated WindPact Plus | $1,250-$1,780 |
What drives the range: size (anything over 40 × 60 inches jumps a labor tier), second-story access requiring scaffolding, and whether the original installation used proper flashing or we need to remediate water damage in the rough opening. Every quote we write in Davie includes the measured survey you keep, a line-item scope with part numbers, and the 365-Day Done Right Promise stamped on the document. The price on that paper is the price on the final invoice. Haven Clause 1.
DIY or Call Us?
There is safe checking and there is risky work. A homeowner can verify the CWS model label location and photograph any visible damage; that saves us ten minutes on arrival. What goes wrong fast: removing a CWS sash without supporting the balance assembly sends the coil spring into the frame cavity or, worse, toward your face. We’ve extracted springs from Davie drywall and once from a homeowner’s forearm. The balance system stores roughly 15 pounds of tension in a standard double-hung. We do not recommend DIY balance, IGU, or full-frame replacement.
If you are holding a competitor’s written estimate for CWS work, bring it to us. Our Free Second Opinion means we review their scope and pricing at no charge, then write our own measured survey so you have two documented numbers to compare. Call (754) 254-8492 to schedule.
FAQs
Seven to twelve years for hardware in coastal Davie, twelve to twenty for the vinyl frame itself, and eight to fifteen for IGUs depending on elevation and exposure. South-facing units in Pine Island Ridge typically hit the shorter end from thermal cycling and salt air. Call (754) 254-8492 for an exact assessment of your openings; estimates are free.
No. Once the IGU seal fails and moisture enters the airspace, the desiccant inside the spacer bar is saturated and the low-E coating may have degraded. Defogging services drill holes and apply a coating; we have measured the resulting U-factors and they perform 30-40 percent worse than replacement IGUs. We replace the glass unit with a new CWS-compatible IGU under the 365-Day Done Right Promise. Call (754) 254-8492 for a written quote.
One to two hours per opening for sash or IGU replacement, four to six hours for full-frame replacement including interior trim remediation. A typical Davie home with eight to twelve openings is a two-day job. We do not promise same-day completion for full-frame work; the install requires proper curing time for sealants and flashing tape. Call (754) 254-8492 to schedule your measured survey.
Yes. We carry WindPact Plus and Series 1000/2000 balances, keepers, tilt latches, glazing beads, and common IGU sizes. For custom-color CWS frames or oversized units, we order factory-direct with a ten to fourteen day lead time and confirm the part number against your measured survey before anything ships. Call (754) 254-8492 to verify stock for your specific model.

Measure it right the first time. Everything else follows from that. Sonia Raman and our crew have served Davie for several years now, including full-frame replacements in Pine Island Ridge where the original 1990s CWS aluminum units had welded corners that finally stress-cracked after two decades of Florida thermal cycles. We write the price before we lift a tool, and we leave you the photo record when the job is done.
