CGI Door Installation Nationwide

CGI Door Installation: The San Francisco Owner’s Guide

CGI door installation in San Francisco typically runs $850 to $2,400 installed, depending on the panel type, hardware condition, and whether the frame needs retrofitting. We stock CGI-compatible parts on our trucks and can complete most single-door installations in one visit, usually within three to four hours. Most homeowners find out their CGI door has a problem the hard way: the panel binds against the jamb, a hinge shears off a mounting screw, or water starts seeping under the threshold after a storm.

This page is written for the CGI owner who wants it done once and done right. We’ll cover which models this applies to, what fails first, what a fair price looks like in San Francisco, and when DIY crosses into dangerous territory.

Key Takeaways

• Typical installed cost in San Francisco: $850 to $2,400 for a single CGI door replacement or installation
• Most common failure points: threshold seals, hinge hardware, sagging panels on older frames
• Turnaround: most jobs completed same-day once parts are confirmed
• Warranty: every installation covered in writing under our 365-Day Done Right Promise
• We’re independent: Meridian Windows & Doors is not affiliated with CGI, but we’re authorized to install and replace their full product line

Which CGI Models This Applies To

CGI manufactures impact-rated doors across several lines, and the installation details change depending on which one you own. The most common we see in San Francisco are the Estate Collection, the Sentry series, and the Targa line. Estate and Sentry doors use a reinforced aluminum frame with an interlocking center mullion on double doors. Targa is a more contemporary profile with a thinner stile and a different hinge prep. If you order a Sentry hinge for a Targa door, it won’t seat correctly. That’s the kind of mismatch that turns a simple swap into a frame rebuild, and we’ve seen it happen more than once.

To identify your model, check the bottom edge of the door panel. CGI stamps a product label there with the series name, production date, and a serial number. If the label is gone, measure the hinge to hinge spacing and the panel thickness. CGI doors in California are most commonly 1-3/4 inches thick, and the hinge spread ranges from 36 to 48 inches depending on the series. Send us those three pieces of information and a photo, and our crew can confirm compatibility before we schedule the visit.

On the OEM versus aftermarket question: for seals, sweeps, and rollers, quality aftermarket parts work fine and cost less. For hinges, strike plates, and multi-point lock assemblies, we recommend OEM. CGI’s hardware geometry is specific, and an aftermarket hinge that’s off by a millimeter will cause the panel to sag within a year. We stock both, and we’ll give you a straight recommendation based on what your door actually needs.

Signs Your CGI Door Installation Is Failing

• Water pooling at the interior threshold after rain. The threshold cap or sill pan has failed, and in San Francisco’s damp winters this won’t self-correct. Left unrepaired, it rots the subfloor beneath the door.
• The door drags or scrapes the sill. A hinge has worked loose or the frame has shifted. On older San Francisco homes, foundation movement is common, and a dragging panel is usually the first sign the frame needs re-shimming.
• The multi-point lock won’t throw all the way. CGI doors use a three-point locking system, and when one roller or hook is misaligned, the whole assembly binds. Forcing the handle is how lock rods get bent.
• You can see daylight or feel a draft around the panel edges. The weatherstripping has compressed or torn. On an impact-rated CGI door, the seal isn’t just comfort, it’s part of the door’s performance envelope.
• The door closes on its own or drifts open. The frame is out of plumb, and the hinges are carrying the door’s weight at an angle. Over time this shears hinge screws or strips the screw holes in the frame.

Replacement Cost & What’s Included

Here’s what a CGI door installation costs in San Francisco as of 2026. These are installed prices, including labor, fasteners, sealant, and a written warranty.

• Threshold replacement: $250 to $500
• Single hinge replacement with re-shimming: $180 to $350 per hinge
• Full weatherstripping and sweep replacement: $150 to $400
• Complete single-door installation (new CGI panel plus hardware): $850 to $1,500
• Double-door installation with new frame: $1,800 to $2,400

The cost driver is the frame. If the existing frame is square, level, and solid, the job is fast and the price sits at the low end. If the frame has pulled away from the rough opening or the subfloor has moisture damage, we’re rebuilding rather than swapping, and the price reflects that. We write the price down before any work starts, and it doesn’t move at the door. No change orders, no extras you find out about after the panel is off. Every CGI installation we do is covered in writing for 365 days. If it fails within that year, we come back and fix it at no charge.

DIY or Call Us?

Replacing a worn sweep or tightening a hinge screw is fine to do yourself. Those are low-risk fixes. But anything involving the multi-point lock assembly, frame re-shimming, or panel removal is where we tell people to stop. A CGI door panel weighs 80 to 150 pounds depending on the series and glass pack. When the hinge pins come out, the panel is free, and one slip is how crushed fingers and broken glass happen. That’s not a scare tactic. It’s what we’ve seen.

If you’re uncertain whether your issue falls on the safe side of that line, call us at (831) 273-7126 and describe what you’re seeing. We’ll give you a straight answer over the phone about what’s safe to attempt and what isn’t. A meridian is a fixed line you measure everything against. That’s the name, and it’s how we approach every job: a clear standard, communicated plainly, and met every time.
