CGI Sliding & Patio Doors: The Fort Lauderdale Owner’s Guide

CGI sliding and patio door repair in Fort Lauderdale typically runs $340-$1,200 for part replacement and $1,800-$4,500 for full unit replacement, depending on whether we’re swapping a roller assembly, track system, or the complete impact-rated panel. We stock common CGI rollers, handles, and locking hardware on our trucks, and most part replacements are completed in a single visit. Most Fort Lauderdale owners first notice trouble when the door sticks during afternoon humidity spikes or when the lock won’t engage after a tropical storm season - signs that salt air has corroded the roller housing or the frame has shifted in its pocket.

Which CGI Models This Applies To

CGI’s sliding and patio door lineup breaks into three series we see regularly in Fort Lauderdale: the Impact Resistant 3750 Series, the Sentinel by CGI line, and the Estate Collection for higher-end installations. The 3750 Series uses a 2-1/4 inch roller housing with a stainless steel axle - most common failure point we find in beachfront properties from Harbor Beach to Lauderdale-by-the-Sea. Sentinel units carry a narrower 1-3/4 inch roller with a nylon wheel that degrades faster under UV load but runs quieter when new. Estate Collection hardware is proprietary; the mortise lock set and keepers aren’t interchangeable with the other two lines.

Identifying your model starts with the etched marking on the glass spacer or the interior frame label, usually found on the jamb side of the fixed panel. If the label is gone, measure the roller housing width and count the wheel count - single wheel versus tandem roller tells us which generation you have. We carry both OEM CGI hardware and qualified equivalents from C.R. Laurence and Truth Hardware where the spec matches; for Estate Collection locks, OEM is the only reliable path because the keeper geometry varies by production year. We are an independent service provider - not affiliated with CGI - and we source through their authorized distribution channel in Miami-Dade.

Signs Your CGI Sliding & Patio Door Is Failing

• The door sticks or skips along the track. This usually means the roller axle has corroded or the wheel bearing has seized. In Fort Lauderdale’s salt-air environment, we see this most often on east-facing doors within three blocks of the Intracoastal, where the roller housing floods with condensation overnight and the grease washes out by year four or five.
• You need two hands to lift the panel before it will slide. The roller has collapsed or the adjustment screw has backed out completely. On CGI’s tandem roller assemblies, once one wheel fails, the second carries double load and wears flat within weeks.
• The lock thumb-turn rotates but the bolt doesn’t throw. The mortise lock gearbox has stripped, typically from forcing the lock when the door is out of square. CGI’s earlier Estate Collection locks used a zinc alloy gearbox that cracks under torque; later runs switched to brass, but the footprint differs by 1/8 inch.
• Visible daylight between the sash and frame when closed. The panel has dropped on worn rollers or the interlock weatherstrip has compressed past recovery. This isn’t just an air leak - on an impact-rated unit, it compromises the design pressure rating and may void your wind mitigation inspection.
• Grinding or popping sound when operating. The track itself is damaged, usually from a failed roller dragging metal across aluminum. Once the track groove is scored, replacing rollers alone won’t fix it; the track cap or full sill replacement becomes necessary.

Replacement Cost & What’s Included

What drives the range: roller diameter and axle material (stainless commands a premium over plated steel), whether the frame pocket needs re-shimming, and access difficulty - second-story balconies in Coral Ridge or Galt Mile add ladder time. Every job gets a written line-item quote before work starts; the measured survey you keep and the final invoice are the same document. Our 365-Day Done Right Promise covers the installation and hardware function, not wear from continued salt exposure - we’ll document what we found and what to expect.

DIY or Call Us?

There’s a safe middle ground and a hard stop. An owner can check whether the roller adjustment screw has backed out - it’s visible at the bottom rail edge, usually a Phillips head - and whether debris is packed in the track drain holes. A vacuum and silicone spray on the track surface (never the rollers themselves) can buy time.

Where DIY goes wrong: lifting a CGI impact-rated panel to access rollers requires knowing the weight - a standard 6-foot panel runs 180-240 pounds - and the correct pry point to avoid bending the bottom rail. We’ve replaced too many frames where a homeowner used a screwdriver as a lever and kinked the interlock. The roller housing also sits in a pocket with a specific clip orientation; forced removal cracks the nylon retainer. If your door is out of square, adjusting rollers without checking the head jamb level makes the lock misalignment worse. Call (754) 666-7478 and we’ll measure it right the first time or measure it twice on someone else’s dime.
