CGI Windows & Doors: The San Francisco Owner’s Guide
CGI window and door replacement in San Francisco typically runs $5,310 to $17,700 installed for full units, while hardware and component swaps (rollers, balances, weatherstripping, locks) generally land between $220 and $850 depending on the part and access. We stock common CGI-compatible hardware on our trucks, and most component replacements go in same-day once we confirm the series and size. Most homeowners discover a failed part the hard way: a sliding panel that suddenly drags, a crank operator that spins without moving the sash, or a door that won’t seal against the morning fog anymore. That fog is exactly what makes CGI hardware work harder in San Francisco, where salt air and moisture cycles age rollers and weatherstripping faster than inland locations.
We’re an independent service provider, not affiliated with CGI. What we offer is straight parts knowledge, honest pricing in writing before work starts, and a one-year guarantee on every replacement we install.
Which CGI Models This Applies To
CGI builds impact-rated windows and doors for coastal markets, and San Francisco homeowners typically have either the Estate Collection, the Sentinel line, or older Classic-series units. The compatibility gotcha matters here: CGI changed its roller housing dimensions between the Classic generation and the current Sentinel series. A roller that fits a 2006 Classic slider will not seat correctly in a 2019 Sentinel frame, even when the door width is identical. If you’re trying to match parts yourself, pull the manufacturer label first. It’s on the side jamb of the window sash or the top edge of the door panel, and it lists the series code, the glass package, and the manufacturing date. That label is what lets us match hardware without guesswork.
For windows, the operator mechanism on CGI casement and awning units differs from standard hardware because of the reinforced frame design. You can’t swap in a generic operator arm and expect it to clear the impact-rated joinery. We order OEM hardware for operators and locking mechanisms, which matters for the product’s structural integrity. For rollers, tracks, and weatherstripping, we use OEM when it’s available and quality aftermarket equivalents when the OEM part is discontinued or backordered. We’ll tell you which choice we’re making and why, in writing, before we order anything.

Signs Your CGI Windows & Doors Is Failing
- Sliding panel drags or sticks mid-track. The roller wheels have flattened on one edge, which is common after eight to ten years of San Francisco fog exposing the bearings to constant moisture. The fix is new rollers, not track lube.
- Crank feels like it’s chewing gravel. The operator gear inside the housing has stripped teeth. On CGI units this often happens because the original installer didn’t set the sash plumb, so the operator has been fighting an misaligned window for years.
- Draft or visible light through a closed window or door. Weatherstripping has compressed or torn, usually along the bottom sweep on doors and the pile gasket on window sashes. Bay-facing elevations lose this seal first because of constant wind pressure.
- Lock or multi-point mechanism won’t fully engage. The lock body has shifted out of alignment with the strike plate as the frame settled, or internal pins have worn. On CGI multi-point hardware, this is a safety issue, not just a convenience fix.
- Condensation or haze between glass panes. The sealed unit has failed. The desiccant inside the spacer is exhausted and the insulating gas is gone. That means an insulated glass unit replacement, not a hardware fix.

AfterReplacement Cost & What’s Included
In San Francisco, expect these installed price ranges for CGI-compatible work:
- Roller replacement (sliding glass door): $220 – $460 per panel
- Weatherstripping replacement (window or door): $180 – $520 per unit
- Crank operator replacement (casement/awning): $310 – $710 per window
- Multi-point lock replacement: $410 – $850 per door
- Insulated glass unit replacement: $710 – $2,310 per sash
- Full window replacement (CGI-compatible): $5,310 – $17,700
The range depends on access – second-story windows on Victorian-era frames add labor time – and whether we’re doing a component swap or a full unit replacement. Every quote includes the part, the labor, haul-away of the failed component, and a written price before we start. No numbers move at the door. And because this is Bradford Remodeling Co San Francisco, every completed replacement carries our 365-Day Done Right Promise: if the part fails or the work doesn’t hold within a year, we come back and make it right at no charge.
DIY or Call Us?
You can safely identify your CGI series by reading the manufacturer label, and you can clean tracks and apply a dry silicone lubricant to a window that’s just sluggish. That’s the extent of what we recommend. Replacing rollers on an impact-rated door requires pulling a panel that weighs 150 pounds or more in some CGI configurations, and getting the panel out of the frame without damaging the track means knowing how to tilt it at the right angle. Multi-point lock swaps are even less forgiving – those mechanisms sit inside a reinforced steel rail, and the lock body is under spring tension through the actuation gears. If it’s not timed correctly, the door doesn’t just fail to lock; it can jam shut in the locked position, which turns a morning repair into a lockout. Curtis Lane has pulled more than a few of these apart over the past two decades, and the ones that went smoothly were always the ones where the homeowner didn’t attempt it first. If you’re in San Francisco and you’re seeing any of the symptoms above, call (831) 610-5598 and we’ll give you the straight number before anyone picks up a tool.
FAQs
Rollers and weatherstripping on CGI units in San Francisco typically last 8 to 12 years before they need replacement, with west-facing and ocean-adjacent elevations failing on the early end of that range due to constant salt-air exposure. Operators and multi-point locks can last 15 to 20 years when the frame stays plumb, but they fail early when the original install was out of square. Call (831) 610-5598 and we’ll assess what’s actually worn before recommending anything.
Roller assemblies and multi-point lock bodies generally cannot be meaningfully repaired once they fail. The internal components are small, machined parts that can’t be sourced individually. We recommend replacement of the full assembly when the housing shows wear, because patching a failing mechanism always costs more in a second visit than doing the full swap the first time. We’ll show you the failed part before we install the new one.
A typical roller or weatherstripping replacement on one panel takes 45 to 90 minutes once we’re on site, and a multi-point lock swap runs 90 minutes to two hours, including re-timing the actuation gears. Full window or door replacements take a day for one or two units and longer for multi-unit work. We’ll give you a time window in writing before the job starts.
We carry common CGI roller assemblies, pile gaskets, and operator arms for the Estate and Sentinel series on our trucks, so most component repairs are done in one visit. Less common parts, including multi-point lock bodies and insulated glass units, are ordered to spec once we’ve confirmed the series and size from the manufacturer label. We also stock hardware for other premium brands, including KraftMaid, Cambria, and Silestone.
Straight number, real scope, no surprises at close-out. That’s how we run every CGI windows and doors replacement in San Francisco. Call (831) 610-5598 to schedule your free estimate, and you’ll get a written price before any work begins.
