AfterCGI Windows & Doors in San Francisco, CA | Hale Windows & Doors
We provide independent CGI window and door service across San Francisco, from the Outer Sunset to the Western Addition. The one thing that makes our CGI work different here is that we’re not manufacturer-affiliated, so our advice, repair or replace, is based on what your building actually needs. Call (252) 675-6980 for a free estimate on Window Repair in San Francisco. We know CGI’s product lines cold, and we know how San Francisco’s preservation rules, fog, and older housing stock change the repair equation for them.
Why San Francisco Residents Choose Us for CGI Service
Spencer Odell, our owner, spent his teenage summers re-glazing single-pane windows in older craftsman bungalows, where he learned early that a bad seal costs homeowners far more than the install ever should have. He carried that lesson into nearly two decades of measuring, ordering, and setting windows and doors, and into how we approach every CGI job in San Francisco. We’re an independent company, part of the Threshold Group, founded in 2009. We stock OEM CGI replacement sashes, balances, and weatherstrip for common series, and for discontinued lines we use aftermarket components that meet or exceed original specs. When we quote a job, you get a written price before any work begins, and every repair carries a written guarantee; if it fails, the second visit is free. That’s the 365-Day Done Right Promise, and it applies to every CGI window and door we touch in San Francisco.
Common CGI Windows & Doors Problems We Solve in San Francisco
- Rusted-shut steel casements in the Sunset and Richmond. The 1930s – 40s CGI steel casement windows in these districts rust at the hinges and latch points from decades of salt-laden fog air. They seize shut, and wind-driven rain leaks into the wall cavity. We repair what’s salvageable and replace what isn’t, using stainless steel hardware on the new work.
- Sash sag and failed counterbalance springs in Victorian and Edwardian flats. CGI vinyl single-hung windows in these older buildings rarely sit in square rough openings. The stress sags the sash and kills the balance springs, which leaves drafts and condensation. We reset the frame, replace the balances, and seal the opening properly.
- Galvanic corrosion on high-rise storefront systems. Along the fog belt, CGI aluminum storefront and curtain wall systems develop corrosion where stainless steel fasteners meet aluminum frames, especially on ocean-facing elevations. That corrosion eats the weather seals and lets water through. We replace the fasteners, restore the frames where possible, and reseal.
- Flashing failures on garden and bay windows in Marina-style flats. The roof-to-window transition on CGI garden and bay windows fails often in these 1920s – 30s buildings. Water rots the underlying wood header, and you don’t see it until plaster stains appear inside. We pull the window, repair the header, and reflash the transition correctly.
- Condensation and fogged glass on coastal exposures. San Francisco’s damp, cool air means constant condensation on single-pane and failed-seal CGI units near the coast. When the glass seal is gone, the unit won’t perform. We replace the glass where the frame is sound, and the full unit where it isn’t.
CGI Service in San Francisco: What Local Conditions Mean for Your Equipment
Here’s the San Francisco reality that most window companies from outside the Avenues miss. In the Sunset and Richmond districts, the original 1930s – 40s steel casement windows are often rusted shut or leaking, and because they sit flush with the stucco, swapping them for modern vinyl or fiberglass units usually requires custom panning and stucco repair. A general contractor from San Jose or Sacramento will underestimate that job every time. We don’t, because we’ve done it repeatedly. When we handled our Window Replacement in San Francisco for a set of rusted-shut CGI steel casements in a 1930s stucco flat in the Outer Sunset recently, we custom-panned each opening, repaired the stucco, and installed CGI Vinylmax single-hung units with stainless steel hardware to handle the salt air and wind-driven rain. The owner told us the living room was finally usable on foggy evenings without a blanket. The new units passed the city’s seismic anchoring inspection without a hitch.
San Francisco’s Planning Department also changes how CGI work plays out here. Any street-facing window change on a building rated as a potential historic resource, even if it’s not in a designated district, can trigger a Historic Resource Evaluation. On CGI replacements in areas like the Western Addition or Inner Sunset, we often have to document original wood profiles and match them in a modern frame rather than defaulting to a standard vinyl extrusion. That’s the difference between a contractor who works in San Francisco and one who just visits.
CGI Models & Products We Service in San Francisco
We service the CGI product lines most common in San Francisco’s housing mix. The CGI Vinylmax Series, both single and double hung, shows up in Victorian and Edwardian flats throughout the Mission, Noe Valley, and the Haight. The CGI 3000 Series Horizontal Roller is common in postwar Sunset and Richmond tract homes. The CGI 8000 Series vinyl impact windows appear on higher-wind coastal elevations, and the CGI Aluminum Series storefront and curtain wall systems dominate post-1970s high-rises downtown and along the Embarcadero. For common series, we stock OEM CGI replacement sashes, balances, and weatherstrip locally for fast turnarounds. For obsolete lines, we use aftermarket parts that meet or exceed original specs. Our depth across these lines is why homeowners and HOA boards across San Francisco call us first for CGI sales & service.

FAQs – CGI Windows & Doors in San Francisco
Yes, but with conditions. San Francisco’s Planning Department requires a Historic Resource Evaluation for any street-facing window change on a building rated as a potential historic resource, even outside a designated district. In practice, that often means the new window must match the original wood profile and color in a modern frame rather than defaulting to a standard vinyl extrusion. We handle that documentation and match the profiles in the CGI line where possible. Call (252) 675-6980 and we’ll tell you what applies to your building before you spend a dime.
Because caulk isn’t the problem. In Richmond District flats from the 1930s – 40s, the original CGI steel casements often sit flush with the stucco, and the failure is usually at the hinge and latch points, where decades of salt-laden fog air have rusted the hardware and broken the weather seal. Caulk over that just traps the moisture. The fix is restoring or replacing the hardware, and often custom panning and flashing rework. Call (252) 675-6980 for an exact diagnosis, estimates are free.
If the frame is square and the roller track is intact, we can replace just the glass. If the frame is rusted, sagging, or the track is worn, glass-only is a short-term fix that will fail again. We’ll tell you straight which one applies to your unit. Call (252) 675-6980 and we’ll assess it on site.
Insert replacement fits a new CGI unit inside the existing frame. Full-frame replacement removes the entire old frame down to the rough opening and installs a new one with fresh flashing. In San Francisco, the choice often comes down to preservation rules and the condition of the original frame. If the frame has rot from wind-driven rain or rust from salt air, full-frame is the smarter long-term investment. Call (252) 675-6980 and we’ll walk you through the tradeoffs for your specific building.
Yes. The salt-laden air near the coast corrodes hardware faster than inland, and the constant damp promotes condensation on seals. We recommend annual inspection and lubrication of hinges and latches on CGI steel casements and aluminum storefront systems, and prompt replacement of any failed weatherstripping. It costs less than a rotted header. Call (252) 675-6980 if you want us to take a look.
