CWS Sliding & Patio Doors: The West Palm Beach Owner’s Guide

We stock and install CWS-compatible sliding and patio door replacement units in West Palm Beach, with installed pricing typically running $1,800 to $4,200 depending on frame material, impact rating, and opening size. Most CWS series units are available for measured survey within 48 hours, and we carry common roller, track, and handle hardware on our trucks for same-day field repairs when the frame itself is sound. Homeowners usually discover the problem when the door sticks during afternoon humidity, when rollers grind audibly across the track, or when they notice daylight between the sash and the jamb that wasn’t there last season.

Which CWS Models This Applies To

CWS produces sliding and patio door systems across several series, and the parts are not interchangeable between lines. The CWS 312 Series uses a 1-3/4 inch roller housing with a stainless steel axle, while the CWS 5500 Series shifted to a 2-inch nylon-tandem roller assembly with a wider load plate. The CWS Impact Series and CWS Estate Collection use heavier-duty hardware to meet Miami-Dade HVHZ requirements, with track depths running 2-1/2 inches versus the 2-inch standard on non-impact units.

To identify your series, check the etched marking on the glass spacer or the label on the door jamb; CWS stamps the series code and manufacturing date, not just the NFRC rating. We match against this code when ordering, not against visual similarity. For rollers and handles, we stock both OEM CWS hardware and verified equivalents from Truth Hardware and Prime-Line that meet the same load and cycle specifications; the OEM part runs 15-20% higher, and we note the source on your written quote so you choose. Sightline Windows & Doors West Palm Beach is an independent service provider, not affiliated with CWS.

Signs Your CWS Sliding & Patio Door Is Failing

• The door requires shoulder weight to move. This usually means the roller axle has flattened or the bearings have seized, often from salt-air corrosion along Flagler Drive and other waterfront properties where we work regularly. The roller housing deforms slowly, so owners adapt until the track itself starts to wear.
• Visible gap at the meeting stile or sill. The interlock weatherstrip compresses permanently after 6-10 years in South Florida’s UV exposure, or the door has dropped on its rollers and no longer sits plumb. Either way, you’re losing conditioned air and gaining water intrusion risk during West Palm Beach’s summer storms.
• Grinding or popping sound when operating. The roller has cracked or the track has developed a burr from metal-on-metal contact. Continuing to operate it scores the track, turning a $180 roller replacement into a $900 track-and-roller job.
• Lock mechanism spins without engaging. The mortise lock gearbox has stripped, common on CWS units with multipoint hardware after heavy daily use. The handle feels loose because the internal cam no longer throws the bolts into the keepers.
• Condensation between glass panes. The insulated glass unit (IGU) seal has failed; this is not a hardware issue but often presents alongside roller problems on older installations. The glass must be replaced, not defogged.

Replacement Cost & What’s Included

The range reflects frame material (vinyl versus thermally broken aluminum), impact rating requirement, and whether the rough opening needs correction. Every quote we write in West Palm Beach includes the measured survey you keep, the specific part numbers, labor, disposal, and the 365-Day Done Right Promise under Haven Clause 5: No Surprises. If the number isn’t on the page, it isn’t in the price.

DIY or Call Us?

An owner can safely check whether the door is obstructed by debris in the track or whether the lock thumbturn is simply loose; a vacuum and a Phillips screwdriver handle that. What we caution against: removing a CWS sliding panel without understanding the anti-lift block location, or attempting to extract a seized roller without supporting the 80-120 pound sash weight. The panel can drop, the glass can fracture, and the track can bend. We carry the suction cups, panel jacks, and alignment gauges on every truck; the tools to do this safely cost more than most homeowners will spend for a single repair. If you’re uncertain which CWS series you have, or if the door has dropped more than 1/4 inch, call (561) 354-3861 and we’ll schedule a measured survey. The estimate is free, and you’ll have the written scope before any work starts.
