CWS Window Replacement: The Plantation Owner’s Guide

CWS window replacement in Plantation typically runs $340-$780 per opening for standard vinyl and aluminum units, with impact-rated CWS models landing between $890-$1,450 installed. We stock common CWS sash, frame, and hardware configurations for same-day replacement on most residential series, and we carry the measured survey to verify fit before ordering anything custom. Most Plantation homeowners discover a CWS window needs replacement when the sash won’t stay open, they feel draft at the meeting rail, or they spot frame separation at the weep holes after a heavy rain.

Which CWS Models This Applies To

CWS manufactures three residential lines you’ll find across Plantation: the WindPact Plus impact-rated vinyl series, the Aluminum Series 5000 non-impact line common in Jacaranda and Plantation Acres builds from 2015-2020, and the WindPact HD high-velocity impact line required for newer HVHZ compliance. The label is usually etched into the glass spacer or stamped on the frame jamb; if it’s worn off, we measure the frame depth (2-5/8″ for WindPact Plus, 3-1/4″ for HD), check the interlayer thickness at the edge, and match the balance shoe color code, white or black, which CWS uses to denote sash weight range.

We are an independent service provider, not affiliated with CWS. For WindPact Plus units, we typically source OEM sash packs direct from CWS distribution in Medley, but for the Aluminum Series 5000 we’ve found the aftermarket frame extrusions from CECO match the original sightline within 1/16″ and carry the same AAMA certification, at roughly 15% less lead time. The gotcha is the balance system: CWS switched from constant-force to block-and-tackle balances in 2019, and the shoe widths differ by 3/32″. We verify this with the sash removed, because ordering the wrong balance means a second trip and a delayed install.

Signs Your CWS Window Replacement Is Failing

• Sash drops or won’t stay open. The coil balance has lost tension, or the block-and-tackle shoe has cracked at the cam. In Plantation’s humidity, the nylon components fatigue faster than the manufacturer rates them; we see this at 8-12 years instead of the printed 15-year spec.
• Visible moisture between glass panes. The insulated glass unit (IGU) seal has failed. CWS uses a dual-seal system, but the PIB primary seal degrades faster in south-facing exposures above the garage or pool cage where surface temperatures hit 140°F.
• Frame corner separation or weep hole blockage. The fusion-welded vinyl joint has stress-cracked, or debris has packed the weep channels. Plantation’s banyan and oak pollen in March and April clog weep systems fast; water then pools at the sill and wicks into the wall.
• Difficulty locking or engaging the keeper. The sash has sagged on a worn balance, throwing the tilt-latch and lock alignment off by enough that the cam lock won’t rotate fully. This is progressive; the first sign is a lock that feels “mushy.”
• Air infiltration at the meeting rail or sill. The wool pile weatherstrip has compressed flat, or the fin seal has torn at the corners. CWS uses a specific 5/16″ pile height on WindPact Plus; generic 1/4″ replacements don’t fill the slot and leak within a season.

Replacement Cost & What’s Included

What drives the range: size, floor height, and whether the original install left proper shimming and flashing. We find CWS units in Plantation’s newer construction, particularly west of University Drive, were installed with minimal expansion gap; removing them without damaging the stucco takes longer. Every replacement includes new fasteners, low-expansion foam, and exterior sealant matched to the substrate. The written quote lists each line item; the invoice matches it. Haven Clause 1.

Workmanship and materials carry our 365-Day Done Right Promise. If the sash doesn’t operate smoothly, the lock doesn’t engage flush, or the weep system drains slow, we return and correct it. The documentation you keep: the measured survey, the written scope with dollar figures, and the photo record of the completed install.

DIY or Call Us?

There’s a safe middle ground. You can verify the model from the label, check the weep holes with a pipe cleaner, and confirm whether the lock issue is debris or misalignment. What we don’t recommend: removing a CWS impact-rated sash without supporting the frame first. The WindPact HD units weigh 45-60 pounds for a standard double-hung; the tilt-latch release requires simultaneous pressure while the sash is angled, and an unsupported frame can rack, damaging the jamb liner and voiding the wall seal. We’ve been called to three Plantation homes in the past year where a homeowner cracked the IGU during removal or lost the balance shoe into the wall cavity.

Our crew carries the specific CWS balance tools, the sash support brackets, and the corner keys in stock. If you’re unsure whether the issue is the glass, the frame, or the hardware, call (754) 704-3597. We’ll schedule a free estimate, measure the opening, and give you a written price before any work starts.
