AfterCGI Windows & Doors in San Francisco, CA | Sightline Windows & Doors
We’re Sightline Windows & Doors, an independent CGI service provider working across San Francisco. If you own a CGI window or door here, the repair or replacement question is rarely simple: San Francisco’s Victorian and Edwardian framing, combined with salt-laden fog in the western districts, creates failure patterns you won’t see with CGI repair in Oakland or Daly City. We service every CGI model line, use OEM parts when the load path demands it, and write you a price before any tool is lifted. Call (509) 265-6387 for a free estimate.
Why San Francisco Residents Choose Us for CGI Service
Most window companies in San Francisco sell you a whole new unit before they’ve looked at the frame. We don’t. Since 2012, Sightline has installed or serviced more than 18,000 openings under the Haven Standard, which means the measured survey you get on day one is the same document as the final invoice. Sonia Raman, our owner, grew up watching her grandfather reglaze Craftsman bungalows in Silver Lake, studied building construction technology at LATTC, and spent two decades measuring and setting windows across Los Angeles County before bringing that discipline to the Bay. She reads rough openings the way a machinist reads a micrometer. If a CGI sash can be rebuilt and keep its original frame, we’ll say so in writing. If the frame is failing, we’ll show you the moisture readings and the rot, then price the full replacement honestly.
We’re CGI sales & service specialists who don’t answer to a manufacturer’s quota. That independence matters when a Planning Department reviewer wants to know whether a repair keeps the original sightline. We can answer that question because we’ve documented the before and after on every job since 2012.
Common CGI Windows & Doors Problems We Solve in San Francisco
- Fogged insulated glass units in the Outer Sunset and Outer Richmond. Salt fog saturates the edge spacer on street-facing IGUs. When the seal fails, argon escapes and condensation forms between the panes. We replace the IGU with a marine-grade low-e unit while keeping the original CGI frame, which often avoids a permit trigger.
- Sticking horizontal roller windows in Edwardian flats. Homes built between 1906 and 1915 have settled. The out-of-square opening transfers uneven load into the roller track, so the sash hops or seizes on the low side. We re-shim the track and replace worn rollers, typically without touching the frame.
- Pitted powder coat on aluminum-clad wood exteriors. Wind-driven salt aerosol in the Richmond and Sunset eats the street-facing finish years before the interior shows wear. We strip, prime, and refinish the cladding or replace the clad components where pitting has reached the wood substrate.
- Seized casement operator arms near the Pacific shore. Constant marine moisture corrodes zinc-plated steel gears inside the operator. The crank turns but the sash won’t move. We rebuild the operator with stainless steel replacement hardware that outlasts the original in this air.
- Dry-rotted sills hidden behind intact interior paint. In the Outer Sunset especially, we regularly pull sills that are fully rotted through on the exterior face while the inside looks fresh. Salt fog penetrates exposed end-grain from the street side. If the sill is the only failed component, we scarf in a replacement and keep the original CGI frame.
BeforeAfterCGI Service in San Francisco: What Local Conditions Mean for Your Equipment
San Francisco requires any window replacement on a building over 50 years old to go through Planning Department review if the new unit is not a like-for-like match in material, sightline, and operation. Even a single-family home is not exempt, because the city treats every visible window as character-defining under Articles 10 and 11 of the Planning Code. That means a CGI storm-rated unit with a thicker frame profile or different glass reflectance can fail review on a Victorian bay, even if it performs better in every measurable way. We know this because we’ve worked with homeowners on Waller Street, in the Richmond, and across the Mission who tried to shortcut the process and ended up with a stop-work order. The honest path is to document the existing window’s dimensions, operation, and sightline before you buy anything, then match those measurements with our Window Replacement in San Francisco that satisfies both the engineering requirement and the Planning Department’s like-for-like standard. We prepare that documentation on every survey.
One of our techs pulled a CGI OceanView fixed picture window from a Queen Anne on Waller Street after the owner noticed permanent fog between the panes. The edge seals had failed because the salt fog on that shaded north-facing wall never dried out, leaving silica beads visible inside the spacer channel. We replaced the IGU with a matching marine-grade low-e argon unit, kept the original CGI frame and exterior trim intact, and the job passed Planning review without a hearing. That’s what a like-for-like repair looks like in San Francisco.
CGI Models & Products We Service in San Francisco
We service the full CGI residential range: the Estate Collection, Targa Series, Classic Series, and OceanView Series. Each line has its own frame geometry, glazing package, and hardware set, and we stock the rollers, operators, weatherstripping, and stainless fasteners that fail most often in marine air. When a repair must preserve the original load path or glass coating, we use CGI OEM components. When the original part is the reason it failed, we source aftermarket equivalents that hold up better here. This covers Window Maintenance & Care for aging units, Energy-Efficient Upgrades like low-e argon IGU swaps, and Full Frame Replacement when the CGI frame itself has rotted or the rough opening shows hidden water intrusion.
CGI Service Pricing in San Francisco
Independent CGI service in San Francisco typically runs from $185 to $480 for hardware and weatherstripping repairs, $340 to $900 for an insulated glass unit replacement, and $1,200 to $3,800 for full-frame window replacement depending on size, floor level, and whether the opening needs structural shoring. Permit fees and Planning Department review time are line items on your written quote, not surprises added later. Your free estimate includes the measured survey, a written scope of work, and the specific CGI parts or aftermarket alternatives we’re pricing. Call (509) 265-6387 and we’ll put the number in your hand before you decide anything.

FAQs - CGI Windows & Doors in San Francisco
No. If the building is over 50 years old and the new window differs from the original in material, sightline, or operation, San Francisco’s Planning Department requires review under Articles 10 and 11 of the Planning Code, even for single-family homes. A hurricane-rated CGI unit with a deeper frame profile or different glass thickness can trigger that review on a Victorian bay. If the replacement is a true like-for-like match, no review is needed, but you’ll want that documented before the work starts. Call (509) 265-6387 and we’ll walk you through the specific requirements for your address.
Fogged IGUs from edge seal failure. The Outer Sunset sits in the fog belt, and the constant salt-laden moisture never gives street-facing glass a dry season. Seals fail, argon escapes, and the unit fogs. We replace the IGU while keeping the existing CGI frame, which typically avoids a permit trigger and costs far less than a full window replacement.
You need the hardware replaced, and usually not the sash. The operator arm’s zinc-plated gears seize in marine air long before the sash itself fails. We remove the old operator, rebuild the mechanism with stainless steel components, and re-set the sash travel. That’s a sub-$300 repair in most cases, not a window replacement. Call (509) 265-6387 and we’ll tell you what we’re seeing before we quote anything.
If the CGI frame is sound and the surrounding wall cavity shows no signs of water intrusion, an insert replacement is usually the right call. If the frame has rotted or the shims have compressed to the point where the opening is no longer square, full-frame replacement is the honest answer. We show you the moisture readings and the frame condition on the survey so you’re not making that decision blind. Estimates are free at (509) 265-6387.
Yes, in most cases. We can replace single-glazed sashes with low-e argon IGUs that fit the original frame, keeping the exterior profile and sightline intact. That typically satisfies the energy code’s U-factor requirement without triggering a Planning Department review. The catch is that the frame must be sound enough to carry the heavier glass. We’ll measure, tell you if it works, and write the price before anything is ordered.
