Here’s how most San Francisco owners discover the problem: the door starts dragging, the handle goes loose, the lock doesn’t catch, or the rollers sound like they’re rolling over gravel. One morning it won’t lock and you realize you’ve been fighting the track for six months. That’s the point to deal with it before the panel comes off its rail entirely.

Key Takeaways:

• CGI doors use specific roller and lock hardware that isn’t interchangeable with generic big-box parts.
• We match parts by the glass label and frame measurements, not by guessing at the showroom.
• Written price before any work starts, same as every job we do in San Francisco.
• Warranty is straightforward: 365-Day Done Right Promise covers the repair and the new part for a full year.

Which CGI Models This Applies To

CGI builds sliding and patio doors across several product families, including the Estate Collection and Classic Collection, plus their hurricane-rated impact lines. The hardware differs between series more than most homeowners expect. What fits an Estate slider won’t always work on a Classic from three years earlier, and the impact-rated doors use heavier rollers built for the added glass weight.

To identify your door, look for the CGI label etched or printed on the glass corner, usually bottom left on the sliding panel. It shows the series, glass type, and sometimes the manufacturing date. If the label is gone, we match by measuring the panel height, the roller housing depth, and the lock backset – the distance from the edge of the frame to the center of the lock hole. That measurement catches more mismatches than anything else, because CGI has shifted that spec between production years.

On the OEM-versus-aftermarket question: we stock OEM-equivalent hardware for most CGI sliders, and we’ll tell you plainly when a quality aftermarket roller or latch is the better value. Some original CGI rollers were manufacturer-specific and we won’t substitute something close if it means the door won’t close tight against the weather stripping.

Signs Your CGI Sliding & Patio Doors Are Failing

• The door drags or catches when you slide it. The rollers under the panel have flat-spotted or the bearings are shot. San Francisco’s marine air accelerates corrosion on the steel bearing surfaces. Once a roller stops rolling, it starts gouging the track and then you’re replacing the track too.
• The handle moves but the latch doesn’t engage. The internal linkage inside the handle mechanism has worn or broken. On CGI doors this is typically a snap-in clip that fails after years of repeated motion. The fix is a new handle assembly, not a can of lubricant.
• The door won’t lock, or it locks but feels like it’s just grazing the catch. Most common cause is the lock misaligned relative to the strike plate, usually after the door settles or the track accumulates grit. If the lock has been forced repeatedly, the latch hook itself may be deformed.
• You hear grinding, squealing, or a metal-on-metal rasp when the door moves. That’s a roller bearing that has lost its seal and run dry. The grease disappeared years ago. Continuing to slide the door on a dead roller wears a groove into the lower track and turns a $200 roller job into a full track replacement.
• Condensation or fog between the glass panes. The insulated glass unit’s seal has failed. Note that CGI doors in coastal San Francisco zip codes deal with salt air and humidity year-round, and seal life on any insulated unit can run 10 to 15 years before moisture creeps in. The glass gets replaced, not repaired – the panel stays in place.

Replacement Cost & What’s Included

For most CGI sliding and patio door part repairs in San Francisco, here’s where the numbers land:

• Roller replacement (both panels): $180 to $340 installed, including new rollers and track cleaning.
• Handle and latch assembly replacement: $150 to $280 installed, depending on series and whether the lock mechanism needs replacement.
• Track repair or replacement: $220 to $520 installed for common aluminum tracks.
• Full sliding panel replacement (impact-rated CGI glass): $1,400 to $3,600 installed.

The range on full panel replacements comes down to the door size, glass rating, and whether the frame and track are still square and usable. Parts are priced separately from labor on every quote we write in San Francisco, so you see exactly what you’re paying for before the work starts. That price doesn’t move at the door. The repair and the new part are covered by our written 365-Day Done Right Promise: if it fails within the year, we come back at no charge.

DIY or Call Us?

There are two things worth doing yourself before picking up the phone. First, clean the bottom track. San Francisco pollen, dust, and that persistent fog moisture turn into a paste that loads up the track and makes good rollers feel shot. A shop vac and a stiff brush solve that in ten minutes. Second, check the visible screws on the handle and lock. Tightening a loose screw is safe and often stops the rattle.

What isn’t safe is pulling the sliding panel to access the rollers. A CGI sliding panel with impact-rated glass can weigh over 200 pounds. Once it’s off the track and in your hands, it’s one awkward twist away from shattering, damaging the frame, or putting someone on the floor. Adjustment screws on the bottom of the panel help sometimes, but forcing a door with a seized roller just chews up the track. At that point, call us at (831) 273-7126 – we’ll match the hardware from the label and do the job in one visit.
