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

We stock and install CGI-compatible sliding and patio door systems in Weston, with typical installed replacement costs running $1,800 to $4,200 depending on the series, size, and whether the opening needs reframing. Most CGI rollers, tracks, and handle sets we carry on the truck, and full panel replacements usually arrive within 3-5 business days. Most Weston homeowners discover the problem when the door starts catching at the sill or when the lock no longer draws the panels tight against the weatherstrip, often after years of silent wear that the Florida humidity and salt air accelerated.

Which CGI Models This Applies To

CGI’s sliding and patio door lineup breaks into three series we see regularly in Weston: the Impact Resistant Series (ES, Estate, and Sentinel lines), the Commercial Series (CMR and CMR-HV), and the Architectural Series (SP6500 and SP9000). The part you need depends on which series you own, and the fastest way to confirm is the etched marking in the glass corner or the sticker on the frame edge, which carries a 6-8 digit SKU beginning with the series prefix.

Rollers differ materially between series. The Estate line uses a 1-1/4 inch stainless tandem roller with a Delrin wheel; the SP9000 takes a heavier 1-1/2 inch brass tandem assembly. Track caps and sill covers are not cross-compatible, even when the panel width matches. We carry OEM CGI rollers and track hardware, plus select aftermarket equivalents from Truth Hardware and Amesbury that meet the same load ratings. For impact-rated units, we stick with OEM on anything that carries the missile-impact certification, because the aftermarket path requires re-certification documentation most homeowners do not want to chase.

Sonia Raman keeps a compatibility sheet in every truck because she once watched a crew waste half a day on a Sentinel panel with an Estate roller that looked close enough. It wasn’t.

Signs Your CGI Sliding & Patio Door Is Failing

• The panel sticks or jumps when you slide it. Usually the roller bearings have seized or the wheel has flat-spotted from carrying weight on a damaged track. In Weston, we see this accelerate when irrigation spray hits the sill repeatedly, washing grease from the axle.
• Visible daylight between the panel and the jamb when the door is “closed.” The locking mechanism or keepers have worn, or the panel has dropped on degraded rollers and no longer aligns with the strike. This gap is where water enters during a driving rain.
• The handle turns but the lock bolt does not engage. The mortise lock internals have corroded, common in homes within two miles of the Everglades where overnight humidity stays above 85 percent for months. The mechanism can feel functional and still fail to throw.
• Condensation between the glass panes. The insulated glass unit seal has failed. For CGI impact-rated doors, this means the entire IGU needs replacement, not defogging, because the interlayer and glass assembly are laminated as a unit.
• The track itself is gouged or the sill cap is cracked. Debris grinding under the roller cuts channels into the aluminum, which then destroys every replacement roller you install. We check this first on every call because replacing rollers on a damaged track is wasted money.

Replacement Cost & What’s Included

For Weston properties, here is what we see on the ground:

The range depends on three factors: the series (Architectural parts cost more than Estate), whether the opening is plumb and square (reframing adds labor), and whether we are matching existing finishes to a multi-panel wall. Every quote we write in Weston starts with the measured survey you keep, and the final invoice matches that document, Haven Clause 1. The 365-Day Done Right Promise covers the installation and hardware function. IGUs carry the manufacturer’s warranty against seal failure, which runs 10-20 years depending on the series year.

DIY or Call Us?

An owner can safely check three things: vacuum the track of debris, confirm the door is not obstructed by a shifted threshold, and verify the lock keeper screws have not backed out. These take ten minutes and solve a portion of sticking complaints.

Beyond that, we recommend calling. CGI impact-rated panels weigh 150-250 pounds depending on size, and the roller adjustment screws sit under spring-loaded load. A panel dropped during a roller swap cracks tile, damages the frame, or injures hands and feet. The mortise lock cavity is machined to tight tolerance; forcing an incorrect replacement jams the mechanism and can damage the stile. We carry the right parts, the right shims, and the documentation that the panel still meets impact rating after our work. Call (754) 812-9260 to schedule your free estimate.
