CGI Windows & Doors in San Francisco, CA | Meridian Windows and Doors San Francisco
We provide independent CGI windows and doors service across San Francisco, from Ocean Beach to the Bayview. What makes our CGI work here different is simple: we know how salt-laden fog, pre-1940 wood framing, and strict preservation rules combine to stress CGI frames, rollers, seals, and sashes. The price goes on paper before any work starts, and every job carries our written 365-Day Done Right Promise. Call (831) 273-7126 to schedule a free estimate.
Why San Francisco Residents Choose Us for CGI Service
Our crew has spent years working on CGI windows and doors across San Francisco’s Victorian, Edwardian, and Mission Revival homes. That gives us field knowledge of how CGI products hold up to fog, salt air, and seismic demands, without any manufacturer authorization. We’re independent. That means when we spec a repair, we’re choosing the fix that serves your house, not one that protects a manufacturer relationship.
Elliot Vance owns Meridian Windows and Doors San Francisco and still walks every job site personally. He learned early that a 100-year-old frame and a modern double-pane unit rarely agree on the first measurement, especially in a city where the west side rots and the east side bakes. Our techs are background-checked, uniformed, and trained on the full CGI sales & service line. We carry OEM CGI hardware and seals when available, and proven aftermarket replacements when the OEM part is discontinued or weeks out.
Common CGI Windows & Doors Problems We Solve in San Francisco
- Fog-driven corrosion on CGI aluminum frames. West-side neighborhoods like the Richmond and Sunset get persistent salt-laden fog, and it pits the anodized finish on CGI aluminum frames within a few years. We address this at the frame level, replacing corroded hardware with stainless steel and resealing the affected sections.
- Roller assemblies seizing on CGI horizontal sliders. Fine sand and moisture intrusion worked into the original tracks, and the rollers on CGI sliders in the Richmond and Sunset often seize as a result. Our tech recently replaced the rollers on a CGI 3-panel sliding door in a 1920s Sunset District home where the tracks had locked up. Stainless steel carriers and a careful realignment, and that heavy panel now glides even on damp, foggy mornings.
- Thermal seal failure in CGI double hung units. When CGI double hung windows on the cooler west side lose their thermal seal, interior condensation between the panes appears during damp mornings. This is a common failure pattern, and it means the insulating gas is gone and the unit has lost its thermal performance.
- Warping of CGI wood-clad sashes on south-facing windows. In the sunnier Mission and Noe Valley microclimates, UV degrades the clad layer on CGI wood-clad sashes. Once the clad layer fails, moisture gets into the wood, and the sash starts to warp. We see this pattern regularly on south-facing exposures.
- Loose or failing hardware on casement windows near Ocean Beach. The constant salt spray and wind load near Ocean Beach works CGI casement hardware hard. We check crank assemblies, hinge rivets, and locking points, and recommend stainless or marine-grade replacements where the exposure justifies it.
CGI Service in San Francisco: What Local Conditions Mean for Your Equipment
In the Richmond and Sunset districts, the persistent salt-laden fog causes standard zinc-plated window hardware to corrode within a few years. That’s a specific, checkable fact that shapes how CGI equipment is maintained here. In fog-free Noe Valley, those same zinc-plated parts might last a decade or more. But on the west side, salt air and condensation sit on the metal every night, and the zinc plating gives up quickly. So many CGI owners in the Richmond and Sunset swap in stainless steel hinges and locking mechanisms despite the higher cost. It’s the difference between a repair that lasts three years and one that lasts fifteen. When we service CGI windows in these fog-belt neighborhoods, we always check the hardware material before we even look at the seals or the glass. If the hardware is zinc-plated and showing white corrosion bloom, we tell you straight: replace it now, or plan to replace it again soon. That’s the kind of local knowledge you don’t get from a manufacturer spec sheet.
CGI Models & Products We Service in San Francisco
We service the full CGI product range you’re likely to find in San Francisco homes: the CGI 7100 Series aluminum casement windows, CGI 8300 Series impact-rated sliding glass doors, CGI 9400 Series single hung windows, and the CGI Estate Collection wood-clad fixed windows. When we spec a repair, we start with OEM CGI hardware and seals when they’re available, because the fit is guaranteed and the warranty stays clean. For discontinued or slow-shipping parts, we use proven aftermarket replacements that match or exceed corrosion resistance. We’re candid about when a full sash or frame replacement beats repeated repairs. On a heavily corroded west-side frame, for instance, repeatedly patching pitted aluminum is throwing good money after bad, and we’ll say so.
CGI Service Pricing in San Francisco
Most CGI service calls in San Francisco run $180 to $340 for a diagnostic visit and common hardware repairs like roller replacement or hinge swaps. Replacing a failed thermal seal unit runs higher, typically $400 to $900 per sash depending on the glass spec and whether the frame is salvageable. Full frame replacement of a CGI window or door starts around $1,200 per opening and goes up with size, impact rating, and the condition of the surrounding framing, which in a pre-1940 San Francisco house is always a variable. The price goes on paper before any work starts, and it does not move at the door. Call (831) 273-7126 for a free estimate on your specific CGI equipment, and we’ll give you written numbers.

FAQs – CGI Windows & Doors in San Francisco
Impact-rated CGI windows are engineered for hurricane wind loads and debris impact, not specifically for seismic racking, but their reinforced frames and laminated glass do hold up better than standard units when a wood-framed San Francisco building flexes during an earthquake. The weak point is usually the connection between the window frame and the old wood rough opening, so on pre-1940 homes we pay close attention to shimming, anchoring, and perimeter sealant. Call (831) 273-7126 and we’ll evaluate your specific openings.
It depends on the district and the door’s position on the house. San Francisco’s landmark preservation rules are strict on street-facing elevations, and impact-rated doors with modern frame profiles often need approval. We’ve worked with homeowners in Victorians near Alamo Square where the planning department required a wood-clad exterior to match the original door style. CGI’s Estate Collection wood-clad options help. If you’re in a historic district, we can spec what the preservation office will likely accept, and you may still need the permit in hand before our Window Installation in San Francisco. Call (831) 273-7126 and we’ll talk through your district’s rules.
CGI wood-clad windows will hold up in the Sunset District as long as the cladding stays intact, but the fog and salt air are relentless on any gap or scratch in the clad layer. Once water gets behind the cladding and into the wood, the sash starts to swell and warp, and the thermal performance drops. We recommend annual inspection of the clad layer and immediate sealing of any breaches. If you’re seeing warping on south-facing sashes, especially in the Mission or Noe Valley microclimates, the damage is likely already beyond a simple repair. Call (831) 273-7126 to get an honest assessment before you spend more on repeated fixes.
Yes, in most Edwardian homes we can install CGI 9400 Series single hung or double hung inserts into the original openings without tearing out the interior trim or exterior siding. The retrofit approach preserves the original window shape and much of the character, which matters for homes in San Francisco’s preservation districts. The catch is that the existing frame must be square and rot-free at the corners. If we find rot around the sill or jamb, as we often do in the Richmond and Sunset where damp air sits against old wood for months, our Window Replacement in San Francisco is the right call. Call (831) 273-7126 and we’ll inspect the actual condition of your openings.
Yes, CGI casement windows near Ocean Beach take more maintenance than the same windows would in the Mission. The combination of salt spray, pressed-in fog, and constant wind loads works the crank assemblies, hinge rivets, and locking points hard. We recommend stainless steel hardware on any exposed window within a few blocks of the surf, and we check and lubricate the operating hardware at least once a year. If you’re already seeing white corrosion or stiff cranking, the hardware is telling you it’s time. Call (831) 273-7126 for an exact quote on your CGI casements, and the estimate is free.
