CWS Sliding & Patio Doors: The Weston Owner’s Guide

We stock and install CWS-compatible sliding and patio door assemblies in Weston, with typical installed replacement costs running $890-$2,400 depending on panel size, impact rating, and whether the frame needs re-roughing. Most CWS rollers, tracks, and handle sets are available same-day from our local inventory, and we carry the full range of CWS series hardware on our trucks. Homeowners usually discover the problem when the door sticks in the wet season, the rollers grind against the track, or the locking mechanism quits engaging - all of which get worse fast in Weston’s humidity and salt-laden air.

Which CWS Models This Applies To

CWS sliding and patio doors fall into three main series you’ll see across Weston: the Windpact Plus impact-rated line, the Series 5500 vinyl sliding door, and the Series 7700 aluminum-framed patio door. The Windpact Plus carries a DP-50 rating and uses heavier tandem rollers with stainless-steel housings - a spec that matters because standard aftermarket rollers will flatten under the panel weight within a year. Series 5500 units use a narrower 1-1/4 inch roller assembly with a Delrin wheel, while the 7700 aluminum line takes a 1-1/2 inch stainless roller with an adjustable stem. The model number is stamped on the hinge-side frame edge or behind the handle escutcheon; if that label’s faded, we measure the roller axle diameter, track width, and panel weight to match the right part.

We are an independent service provider - not affiliated with CWS - and we source both OEM CWS hardware and verified aftermarket equivalents. For rollers specifically, we stock Precision and Prime-Line aftermarket lines that match CWS tolerances, but we default to OEM on Windpact Plus impact units because the interlock geometry is tighter and aftermarket tolerances can compromise the seal. On Series 5500 vinyl doors, we’ve had good field results with heavy-duty aftermarket rollers at roughly half the OEM unit cost, provided the axle length and wheel durometer match.

Signs Your CWS Sliding & Patio Door Is Failing

• The door sticks or requires shoulder force to move. This usually means the rollers have flattened or the bearings have seized. In Weston, we see this accelerate when irrigation spray hits the track repeatedly - the hard water deposits weld the roller to the axle.
• Grinding or squealing when you slide the panel. The roller housing has cracked or the wheel material has degraded. CWS Series 5500 Delrin wheels turn brittle after 6-8 years of UV exposure through Weston’s west-facing patios; the sound is the wheel fragmenting against the track.
• The lock tongue won’t extend fully or catches halfway. The multipoint lock mechanism has corroded internally. CWS uses a stainless-steel tongue with a zinc housing, and the galvanic reaction between those metals shows up reliably around year 7 in coastal Broward County air.
• Visible daylight between the panel and the frame when closed. The panel has dropped on worn rollers, or the interlock weatherstrip has compressed past recovery. On Windpact Plus doors, this gap also breaks the impact rating - the door may still latch but won’t meet code for wind-borne debris protection.
• The handle spins freely or pulls away from the door. The internal spindle has sheared or the mounting screws have stripped out of the aluminum stile. We’ve replaced handles on CWS 7700 series doors where the original zinc screws corroded completely through; we upgrade to stainless fasteners on every replacement.

Replacement Cost & What’s Included

The range depends on three factors: whether the frame opening is still square (re-roughing adds $200-$400), whether the existing CWS unit is a standard or custom size, and whether the failure damaged adjacent components - a seized roller left in service long enough will groove the track beyond repair. Every replacement we quote includes the measured survey you keep, the written scope with line-item pricing, installation by a background-checked and uniformed technician, and the 365-Day Done Right Promise stamped under the Haven Standard. The price we write is the price on the final invoice - no change orders, no surprises.

DIY or Call Us?

An owner can safely check three things before calling: whether the track is clear of debris (vacuum and wipe with a damp cloth), whether the door is actually unlocked (the CWS multipoint lock can feel engaged when it’s not), and whether the roller adjustment screw at the bottom of the panel will raise the door enough to clear the track. What you should not attempt: removing the panel from the frame. CWS sliding panels weigh 80-180 pounds depending on size and glass package, and the top-hung or bottom-roller configuration varies by series - a misjudged lift bends the track or shatters the glass. We’ve been called to Weston jobs where a homeowner dropped a Windpact Plus panel trying to reach the rollers; the re-order cost exceeded what our full service call would have run. If the roller is seized or the lock mechanism is internal, the safe move is to stop and call.

Measure it right the first time. The window does not care how confident you were.
