CGI Patio Door Installation in San Francisco: What to Know First
CGI patio door installation in San Francisco typically runs $1,900 – $4,200 for a standard sliding or hinged unit, depending on the series, frame condition, and whether we’re replacing an existing door or cutting a new opening. As an independent CGI service provider, Meridian Windows and Doors San Francisco installs and retrofits the full CGI lineup, with most jobs completed in one to two days once the door arrives. We put the price in writing before work starts, and every installation carries our 365-Day Done Right Promise.
This page is for CGI owners in San Francisco who need a patio door installed correctly the first time, whether the old unit has failed or the house is ready for an upgrade. If you’re still deciding between repair and replacement, we’ll walk you through that during the estimate. Call (831) 273-7126 and we’ll schedule a time that works.
How CGI Products Fail – and How We Fix Them
CGI builds a serious impact-rated door, but every product line has its known weak spots. Here’s what we see on San Francisco jobs, and what we do about it.
- Roller wear on the Sentry sliding series. CGI’s Sentry sliding patio doors carry a lot of glass weight on two bottom rollers. After years of coastal air and daily use, those rollers flatten or seize, and the door starts dragging. We replace them with OEM-spec rollers when available, or a matched aftermarket set that carries the same load rating, and re-shim the track so the door rolls clean.
- Header sag above wide openings. Wide CGI patio door spans, particularly on newer builds with open floor plans, can develop a subtle header deflection over time. The symptom is a door that locks fine in winter but binds in summer. We check the header with a laser level before touching the door, and if there’s deflection, we address it before setting the new unit.
- Frame corrosion at the threshold on Coastal-line units. San Francisco’s marine layer is relentless. Aluminum frames on older CGI Coastal units can develop pitting at the threshold, which throws the door out of square and lets moisture in. We inspect the sill, replace corroded sections where possible, and flash the new threshold properly.
- Laminated glass delamination on impact doors. Impact-rated glass is a sandwich of glass and a polymer interlayer. If a CGI door has been exposed to years of direct sun on a south-facing San Francisco exposure, we occasionally see edge delamination, a hazy line creeping in from the frame. The fix is an insulated glass unit replacement, which we order to CGI’s exact glass spec.
- Adjustment drift on multi-point locking systems. CGI hinged patio doors use multi-point locks that throw bolts at three points. Over time, the connecting rods stretch slightly and the door won’t latch cleanly. We re-time the mechanism and replace any bent or worn rods, which is usually far cheaper than replacing the door.
Our CGI Patio Door Installation Process
Every CGI patio door job follows the same sequence, so nothing gets missed.
- 1
Site inspection and measurement. Elliot Vance or one of our lead techs measures the rough opening in three places, checks the floor for level, and confirms the door swing or slide direction. He also looks at the existing flashing and the condition of the surrounding framing.
- 2
Parts and unit decision. We determine whether the door needs a full replacement or component-level repairs, and we spec the correct CGI series and glass package for the exposure. OEM parts come from CGI’s distribution network; for discontinued parts, we source matched aftermarket equivalents that meet the original spec.
- 3
Written price. You get the number in writing before any work begins. It includes the door, hardware, labor, disposal, and any framing correction. It does not move at the door.
- 4
Removal and prep. We pull the old unit, inspect the framing for rot or water damage, and repair anything questionable. If the rough opening needs correction, we do it now, not after the door is in.
- 5
Installation. The new CGI door is set, shimmed, leveled, and fastened per the manufacturer’s installation instructions. We flash and seal the exterior, insulate the gap, and trim the interior cleanly.
- 6
Operation test and walk-through. We cycle the door a dozen times, verify the lock throw, and walk you through the operation. Elliot does his own final walk-through on every job, because he’d rather find the gap than hear about it from a homeowner.
What CGI Patio Door Installation Costs in San Francisco
Here are the numbers we quote most often, with materials and labor included:
- Standard CGI Sentry sliding patio door replacement: $1,900 – $2,800
- CGI Estate hinged French patio door replacement: $2,600 – $3,800
- CGI Coastal impact-rated door with full frame replacement: $3,200 – $4,500
- Roller, track, or lock repair (no door replacement): $225 – $650
What moves the price: rough opening condition, whether the existing frame is salvageable, glass package, and access. A third-floor walk-up with a narrow stairwell costs more than a ground-floor slider. We’ll give you an exact written quote after the site inspection.

Every project gets a written price before work starts, and the 365-Day Done Right Promise is in writing on every job: if it fails within a year, we come back at no charge. Our techs are background-checked and uniformed, and a live person answers the phone around the clock. The Garrison Code is what we will and will not do on a job site: show up on time, protect the floors, clean up the debris, and leave the job better than we found it.
FAQs
Yes. We install to CGI’s published installation specifications, using OEM parts where they’re available and matched equivalents when they’re not. As an independent CGI service provider, we’re not authorized by CGI, but our workmanship carries its own written 365-Day Done Right Promise. Call (831) 273-7126 to discuss your specific door.
Most CGI patio door installations are completed in one to two days once the door is on site. If we’re ordering a custom size or a specific glass package, the lead time is typically two to four weeks. We’ll give you a firm schedule in writing before work begins.
If the frame is solid and the glass is intact, repair is usually the cheaper route. Roller, track, and lock work runs $225 – $650. If the door is more than 15 years old, the frame is corroded, or the insulated glass is failing, replacement makes better financial sense. We’ll give you an honest recommendation during the estimate, not the one that pads our invoice.
We stock the common failure items: rollers, lock rods, handles, and weatherstripping for the major CGI series. Oddball or series-specific parts we order from CGI’s distribution network, usually arriving within a week. If a part is discontinued, we’ll find a matched aftermarket equivalent that meets the original load and fit spec.
