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

We stock and install CWS-compatible sliding and patio door systems in Davie, with typical installed replacement costs running $1,800-$4,200 depending on panel count, impact rating, and frame material. Most CWS hardware failures - rollers, tracks, locks, and tandem assemblies - can be diagnosed and quoted same-day, with the part matched to your exact series before we arrive. The way most Davie homeowners discover a problem: the door sticks in the summer humidity, then won’t lock properly, then one morning it jumps the track entirely.

Which CWS Models This Applies To

CWS (Custom Window Systems) produces several sliding and patio door series that have been installed across Davie since the mid-2000s, particularly in the Pine Island Ridge area and newer developments west of University Drive. The most common we encounter are the Impact 5500 Series, Impact 8000 Series, and the non-impact EnergyVue 3000 line. Each uses distinct roller diameters, track profiles, and locking mechanisms that are not cross-compatible.

To identify your series, check the etched CWS logo on the glass corner and the sticker rail on the frame edge. The 5500 uses a 1-1/4 inch tandem roller with a stainless steel housing; the 8000 upgrades to a 1-1/2 inch heavy-duty tandem with a brass wheel option for coastal exposure. The EnergyVue 3000 uses a lighter 1-inch single roller that wears faster under the weight of impact glass retrofits. We carry OEM CWS rollers and tracks, plus a quality aftermarket line from Truth Hardware where the specification matches. Aftermarket saves roughly 15-20% on parts but voids any remaining CWS glass warranty if the roller failure caused frame stress. We document both options on your written quote.

Signs Your CWS Sliding & Patio Doors Is Failing

• The door requires shoulder weight to move. This usually means the tandem rollers have flattened or the axle bearings have seized. In Davie’s salt-air environment, we see this accelerate to 3-4 years on coastal-facing tracks versus 6-8 years inland.
• The handle lifts but the lock bolt doesn’t throw. The CWS mortise lock mechanism uses a zinc alloy housing that fatigues at the cam interface. Once the cam cracks, the lock appears to function but doesn’t engage the keeper - a security gap most owners don’t detect until they test it manually.
• Visible gap at the center meet stile when “closed.” This indicates the adjustable rollers have bottomed out and the panel has settled. On CWS 8000 Series doors, this also stresses the interlock gasket, which then tears and admits water during Davie’s summer storms.
• Grinding or popping sound during operation. The track itself has dimpled or the roller axle has bent. CWS tracks are extruded aluminum; once deformed, lubrication won’t fix it - the track section needs replacement, not just the roller.
• Condensation between glass panes. This is seal failure, not hardware failure, but CWS doors with failed seals often get forced harder, which then damages the rollers and lock. We flag both issues during survey so the quote addresses the root cause, not just the symptom.

Replacement Cost & What’s Included

What drives the range: impact-rated versus non-impact glass, panel dimensions over 96 inches wide (requires two technicians and a heavier roller spec), and frame condition. We quote the exact number before any work starts - Haven Clause 1. The 365-Day Done Right Promise covers all labor; parts carry the manufacturer’s warranty, which we register for you.

DIY or Call Us?

There is one thing a CWS owner can safely check: the weep holes at the track base. If they’re clogged with debris, water backs up and corrodes the roller axle. A toothpick or compressed air can clear them. Everything else carries risk. The tandem roller on a CWS 8000 panel supports 80-120 pounds of glass; if the panel tilts during removal, the glass can fracture or the frame distort. The mortise lock interfaces with a multi-point system - misalignment means the door won’t seal, and you’ll discover that during a storm.

We don’t recommend DIY roller or lock replacement on CWS doors. The specification tolerances are tight, and we’ve been called to jobs where a homeowner installed a generic 1-inch roller on an 8000 Series, which then ground the track to failure within six months. Measure it right the first time. Everything else follows from that.
