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

We stock and install CWS-compatible sliding and patio door systems in Jupiter, with typical installed prices running $1,800 to $4,200 depending on the series and whether impact-rated glass is required. Most CWS hardware failures - rollers, tracks, locks, and tandem roller assemblies - can be diagnosed and quoted same-day, with replacement parts matched to your exact model year and series. Most Jupiter homeowners discover a problem when the door starts sticking in the track during humid mornings, or when the lockset won’t engage after a heavy rain season has swollen the frame.

Which CWS Models This Applies To

CWS sliding and patio doors fall into several series that share some hardware but not all. The most common we encounter in Jupiter are the CWS 312 Series (single-panel slider), CWS 5400 Series (multi-slide and lift-slide systems), and the CWS Impact Series (HVHZ-rated for coastal Palm Beach County). The critical compatibility point is the roller assembly: CWS uses a proprietary tandem roller on the 5400 Series with a 1-1/4 inch wheel diameter and a 3/16 inch axle pin that does not interchange with standard PGT or CGI hardware. The 312 Series uses a simpler single-ball-bearing roller that is more widely available as aftermarket, though we prefer OEM for load distribution reasons.

To identify your series, check the vertical jamb sticker - usually on the hinge side of the fixed panel - for a six-digit CWS order number beginning with the series prefix. If the sticker is sun-faded (common on west-facing Jupiter installations after seven to ten years), measure the roller housing width and the track profile: the 5400 track is a dual-rail extrusion at 2-1/2 inches wide, while the 312 uses a single-rail at 1-7/8 inches. We carry both OEM CWS rollers and a verified aftermarket equivalent from Prime-Line on our trucks, and we document which we used in your photo record.

Sightline Windows & Doors Jupiter is an independent service provider, not affiliated with CWS. We source parts through verified CWS distributors and maintain cross-reference sheets for series compatibility because we’ve learned - particularly on the Indiantown Road corridor jobs - that guessing at roller specs costs everyone a second trip.

Signs Your CWS Sliding & Patio Door Is Failing

• The door sticks or requires shoulder force to move. Usually the tandem roller bearings have seized from salt-air corrosion or the axle pin has worn eccentric. In Jupiter’s coastal environment, we see this at six to eight years on non-impact units and eight to twelve on impact-rated frames with better sealing.
• The door drops on the handle side and scrapes the sill. The roller height adjustment screw has backed out, or the roller housing itself has cracked from repeated impact against the track stop. CWS 5400 housings are aluminum and fatigue faster than the stainless-steel versions used by some competitors.
• The lockset won’t engage or the thumb turn spins freely. The CWS mortise lock mechanism has worn at the cam, or the strike plate has shifted due to frame settlement. On impact-rated units, the heavier door puts more cycle load on this component.
• Visible daylight or water intrusion at the sill after rain. The sill track cap seal has degraded, or the weep holes are blocked with organic debris. Jupiter’s afternoon thunderstorms test this directly; we clear and test weep function on every service call.
• The screen door jumps the track or won’t roll. Screen roller assemblies are smaller and use a 3/4 inch nylon wheel that degrades faster than the door rollers. They’re often overlooked until the mesh frame starts dragging on the track edge.

Replacement Cost & What’s Included

For Jupiter homeowners, CWS sliding and patio door repairs typically break down as follows: roller assembly replacement runs $280 to $520 installed depending on OEM versus aftermarket and whether the track requires resurfacing; lockset or mortise lock replacement is $340 to $680; full track and sill cap replacement ranges $720 to $1,400; and complete panel replacement (when the frame is bent or the glass is compromised) starts at $1,800 and runs to $4,200 for impact-rated, low-E configurations. These prices include the measured survey you keep, the written scope, the part, the labor, and the documented photo record.

What drives the range: the series (5400 parts cost more than 312), whether the door is impact-rated (heavier hardware, different glass package), and whether we find secondary damage when we open the frame. We quote the full scope before any work starts - Haven Clause 1 - and the invoice matches the quote. The 365-Day Done Right Promise covers the installation and the part; if the roller we installed develops play or noise inside a year, we replace it and document why.

DIY or Call Us?

An owner can safely check three things: verify the lockset is fully engaged before forcing the door (a disengaged lock can mimic a roller failure), clear weep holes with a pipe cleaner, and vacuum the track of sand and organic debris. These are diagnostic steps, not repairs.

Where DIY goes wrong: the tandem roller on a CWS 5400 is under significant panel load - a 96-inch by 80-inch impact-rated panel weighs over 200 pounds - and removing it without supporting the door risks panel drop, frame bend, or personal injury. The roller adjustment screw is also easy to strip if you don’t know the CWS-specified torque. We carry the jack, the roller press, and the torque driver on our truck. Call (772) 362-5402 and we’ll quote it in writing before we start.
