CWS Window Installation: The Weston Owner’s Guide
CWS window installation in Weston typically runs $340-$780 per opening for standard vinyl and aluminum replacements, with impact-rated CWS units starting around $620 installed. We stock CWS frame components, sash hardware, and glazing beads for same-day repair on most series, and we carry the full CWS catalog for full-unit replacement when the frame itself has failed. Most Weston owners discover a CWS window problem when the sash won’t stay up on its own, or when they notice daylight between the frame and the wall after a summer storm season - both signs that the installation, not just the part, needs attention.
Which CWS Models This Applies To
CWS produces three residential lines you’re likely to find in Weston homes built between 2005 and 2020: the WindPact series (impact-rated, HVHZ-certified), the Elegance series (vinyl non-impact), and the Builder’s Choice aluminum line common in townhome developments near Bonaventure. The label is usually etched into the glass corner or stamped on the frame edge - look for a four-digit model prefix (WP for WindPact, EL for Elegance, BC for Builder’s Choice) followed by the glass thickness code.
Here’s where owners get tripped up: CWS changed its frame depth from 2-5/8″ to 3-1/4″ on the WindPact series in 2018, but kept the same model prefix. A WP-6200 ordered today will not slide into a 2016 WP-6200 rough opening without modification to the fin or the trim plane. We verify this with a digital caliper reading at three points - top, center, and bottom of the jam - before we write the scope. For hardware-only calls, CWS OEM balances and locks are compatible back to 2012, but the roller assemblies changed thread pitch in 2019; we stock both and match to what we remove.
We are an independent service provider - not affiliated with CWS - and we source both OEM and verified aftermarket equivalents. For CWS specifically, we use OEM glazing beads and weatherstripping because the kerf dimensions are proprietary, but we often specify Truth Hardware or Caldwell balances over CWS-branded units when the spec matches, because the warranty terms are better and the lead time is shorter.
Signs Your CWS Window Installation Is Failing

- Sash drops or won’t stay open. The coil balance system has lost tension, usually from corrosion in the balance shoe. In Weston, we see this accelerate on east-facing windows where morning condensation sits in the jamb pocket until 10 a.m. - the balance housing rusts through in 6-8 years instead of the 12-15 you’d expect inland.
- Visible gap between frame and wall, or light leak at the header. The installation flange has pulled, or the shims have compressed. This is common in Bonaventure and Windmill Reserve homes where the original installer used non-galvanized fasteners that react with the alkaline soil vapor.
- Condensation between glass panes. The IGUs seal has failed. CWS units from the 2012-2016 period used a dual-seal system that held up poorly in Broward’s UV load; we see this pattern enough that Sonia Raman keeps a separate log entry for it.
- Frame corner separation or vinyl warping. Heat buildup in dark-colored frames, especially on south and west exposures near Weston Town Center where reflected light compounds the issue. The CWS Elegance series in bronze or forest green shows this most.
- Lock won’t engage, or engages but sash still rattles. The keep has shifted due to frame flex, or the lock mechanism itself has worn. Often the symptom is the lock, but the cause is installation deflection - replacing the lock without shimming the frame is a temporary fix at best.

AfterReplacement Cost & What’s Included
| Service Level | Typical Range (Weston) | What’s Included |
|---|---|---|
| Hardware repair (balance, lock, roller) | $180-$340 | OEM or matched aftermarket part, removal and reset of sash, operational test, photo record |
| IGU replacement (glass only) | $280-$520 | New insulated glass unit, sealant and setting block, disposal, 5-year glass warranty |
| Sash replacement (frame + glass) | $420-$680 | Matched sash, hardware transfer, alignment and weatherstrip, photo record |
| Full frame replacement (standard vinyl) | $620-$940 | Removal, rough opening inspection, new CWS unit, insulation, interior/exterior trim, Haven Standard documentation |
| Full frame replacement (impact-rated) | $840-$1,380 | HVHZ-certified unit, permit pull, inspection coordination, 365-Day Done Right Promise |
The spread within each range comes down to three things: unit size (a 3050 double-hung vs. a 4030 picture window), wall condition (stucco repair adds $120-$200), and whether the original installation used proper flashing - we find about 30% of Weston retrofits from the 2005-2015 period did not, and we correct it because Haven Clause 4 (Evidence on Every Job) means we document what we found and what we did.
Every job leaves with a written scope, the measured survey you keep, and a photo record. The price on that scope is the price on the invoice - Haven Clause 1. No change orders for conditions we should have seen.
DIY or Call Us?

There is one thing a CWS owner can safely check: open the sash and look for the label. Model, date code, and glass thickness tell you most of what you need to know before calling. If you have a multimeter and know how to use it, you can also check for voltage at a motorized shade integration - but that’s rare in CWS residential units.
What we do not recommend: removing a fixed sash or operating sash without supporting the glass, adjusting or replacing coil balances (stored energy can release suddenly), or cutting stucco to access a fin without knowing what’s behind it. We’ve been called to three Weston homes in the past two years where a homeowner cracked the IGU trying to free a stuck sash, turning a $280 balance call into a $520 glass replacement.
We carry CWS-compatible balances, locks, rollers, and glazing beads on every truck. For full units, we measure, order, and schedule - typical lead time is 10-14 days for standard sizes, 4-6 weeks for custom geometries. Call (754) 812-9260 to schedule your free estimate; we’ll bring the calipers and the catalog.
FAQs
In Broward’s climate, a properly installed CWS vinyl unit should perform for 18-25 years; we’ve seen Builder’s Choice aluminum units go 15-20 before the thermal break degrades. The weak point is usually the balance system at 8-12 years, and the IGU seal at 10-15 years on pre-2017 units. Call (754) 812-9260 for an exact quote - estimates are free.
Sometimes. A balance can be re-tensioned if the shoe isn’t corroded, and a misaligned lock can be shimmed. But a failed IGU cannot be “re-sealed” in any durable way - the desiccant is saturated and the low-E coating may be compromised. We tell you which it is before we write the scope. Call (754) 812-9260 for an exact quote - estimates are free.
A hardware swap takes 45-90 minutes per window. A full-frame replacement runs 3-5 hours per opening, plus stucco or trim repair time. We schedule one opening per day for occupied homes, or multiple per day if the house is vacant. We do not promise same-day completion on full-frame work - the curing time for sealants and the inspection schedule make that unrealistic. Call (754) 812-9260 to schedule your free estimate.
We stock balances, locks, rollers, glazing beads, and weatherstripping for all CWS series on every truck. Full sashes and frames are ordered to measured spec - we do not carry inventory units because Haven Clause 1 requires the measurement and the quote to be the same document, and that only works when we’ve measured your opening. Call (754) 812-9260 for an exact quote - estimates are free.
Measure it right the first time. The window does not care how confident you were.
Ready to get a written price before any work starts? Call (754) 812-9260 to schedule your free estimate. We’ll arrive with a measured survey you keep, a documented photo record, and the CWS specification that matches your opening - not what’s in a warehouse.
