CGI Construction in San Francisco, CA | Toolbox Contractors
We provide independent CGI window, door, and patio door service across San Francisco – repair, replacement, and new installation for homes from the Richmond to Visitacion Valley. The one thing that makes CGI work different here is the seismic movement: San Francisco’s pre-1940 wood-frame buildings shift, settle, and get retrofitted, which means CGI units set into these walls need to be installed and serviced by someone who understands what the structure underneath is actually doing. Call (855) 382-3257 for a straight answer and a free estimate.
Why San Francisco Residents Choose Us for CGI Service
We’ve pulled, reset, and replaced CGI units across San Francisco’s older housing stock long enough to know how these windows and doors actually age in fog-belt damp, salt-laden air, and the constant micro-movement of a wood-frame city. Our crew has worked on CGI aluminum sliding patio doors in the Sunset where the ocean air had pitted the track finish, CGI vinyl double-hungs in the Mission District where the walls had shifted out of square, and multi-panel sliders in Pacific Heights where the original rough openings were never flashed properly. Norm Castellano leads our team, and he came up through construction technology at San Bernardino Valley College before spending decades on framing, roofing, and full gut-and-rebuilds – so when a CGI unit fails, we look at the wall behind it, not just the part in front of us. We’re an independent contractor, not affiliated with or authorized by CGI, and we tell you that up front so there’s no confusion about warranty status. What we offer is honest assessment: repair when the frame and glass are sound, replacement when they’re not.

Common CGI Construction Problems We Solve in San Francisco
- Corroded aluminum tracks and steel hardware from fog and salt air. Homes in the Outer Sunset, Outer Richmond, and anywhere within a few blocks of the Bay deal with persistent salt-laden moisture that attacks CGI door tracks, hinge hardware, and fasteners. Rollers seize, finishes pit, and doors get harder to move every season.
- Sliding doors that jump track or refuse to latch. The out-of-square openings typical of soft-story buildings and hillside homes in San Francisco cause CGI sliders to bind, lift off their rollers, and fail to lock. This isn’t a hardware defect – it’s the building moving, and the fix means resetting the unit plumb and square, not just swapping rollers.
- Moisture intrusion at sills and rough openings in Edwardian and Victorian walls. Many CGI units in San Francisco were set into openings that were never flashed or sealed for wind-driven rain. Water works into the sill, rots the surrounding wood framing, and shows up as peeling paint or a soft spot under the window.
- Fogged insulating glass from seal failure. The wide day-night temperature swings in San Francisco, combined with seismic racking that shifts older walls, stress the glazing seals on CGI units. Fogged glass is the visible symptom; the underlying cause is often movement.
- Windows that stick seasonally. When a San Francisco house settles and re-settles through wet winters and dry summers, CGI vinyl frames can bind in their openings. The window that’s fine in September sticks in February, and the fix is usually an adjustment plus a look at what the wall is doing.
CGI Service in San Francisco: What Local Conditions Mean for Your Equipment
Here’s the thing about San Francisco that changes how CGI windows and doors are spec’d and serviced – and it’s not true in Oakland, Daly City, or anywhere else nearby. San Francisco’s soft-story ordinance requires seismic retrofit of the ground-floor garage level on two- to four-unit wood-frame buildings. That retrofit stiffens and often re-levels the structure, which sounds like good news until you realize what it does to the walls above. Openings that were framed decades ago are now in a different plumb and square than they were when the original CGI units went in. A door that latched fine in 1995 is suddenly binding, dragging, or leaving a gap at the corner. We see this constantly in neighborhoods with dense Edwardian and Victorian rowhouse stock – the Mission, Noe Valley, the Castro, Bernal Heights. On a two-unit Edwardian off Valencia Street, the upstairs owners had a CGI sliding patio door at the rear that hadn’t latched in years. The soft story below had been retrofitted, the rear wall had shifted, and the original opening was out of square and never flashed, so water had been working into the sill. We pulled the door, repaired and re-flashed the rough opening, reset a new CGI slider plumb and square, replaced the worn roller hardware, and the door now latches and seals through the wet season. That’s the San Francisco-specific reality: service here means dealing with what the retrofit did to the wall, not just what the fog did to the hardware.
CGI Models & Products We Service in San Francisco
We work on the full CGI line that shows up in San Francisco homes: aluminum sliding patio doors, vinyl single-hung and double-hung windows, sliding glass and multi-panel door systems, and vinyl-framed sliding windows. When a unit is recent enough to justify it, we use OEM CGI replacement hardware, rollers, and glazing. When OEM availability or cost no longer makes sense – which happens more often with older discontinued lines – we use quality aftermarket parts and tell you honestly which side of that line your unit falls on. We keep common rollers, latch hardware, and glazing options stocked locally so San Francisco jobs don’t stall waiting on parts. Our broader CGI sales & service work has taught us which units hold up and which ones don’t, and we bring that experience to every job we touch.

AfterCGI Service Pricing in San Francisco
San Francisco labor rates run higher than the surrounding region, and so do the materials. Here’s what CGI-related work typically costs in the city, based on the scope we see in our San Francisco service area work:
| Service | Typical Range |
|---|---|
| Window Replacement | $5,310 – $17,700 |
| Impact Window Installation | $9,440 – $29,500 |
| Garage Conversion | $35,400 – $94,400 |
What drives the cost here more than anywhere else is the condition of the rough opening. A CGI window going into a freshly retrofitted wall with plumb, square framing is a straightforward install. A CGI window going into an Edwardian wall with rot, out-of-square framing, and a soft-story garage below is a different job entirely. Our free estimates include a look at the opening, not just the unit. Call (855) 382-3257 for an exact quote.

FAQs – CGI Construction in San Francisco
In most cases, yes. San Francisco’s Department of Building Inspection requires permits for window and door replacement when the openings are altered, when the building is a potential historic resource, or when the work involves structural changes. Rooftop and upper-floor work on hillside lots often triggers additional Planning review. We handle the permit path through DBI and Planning as part of the job, and we’ll tell you during the estimate what your specific building will require. Call (855) 382-3257 and we’ll walk you through it.
No – window replacement alone won’t trigger a soft-story retrofit, but it’s more connected than most people think. San Francisco’s mandatory retrofit program applies to the ground-floor garage level of two- to four-unit wood-frame buildings with specific design conditions, and it triggers on its own based on the building, not your windows. That said, we see a lot of owners replace windows first and then retrofit later, which is why we always check the plumb and square of the openings. If a retrofit is coming, it changes how we set the new units. We’ll tell you what we see.
In San Francisco, the usual cause is out-of-square openings from structural movement – soft-story settling, hillside creep, or the after-effects of a seismic retrofit. The rollers bind, the panel lifts, and the latch no longer lines up. The real fix is resetting the door plumb and square in the opening, which often means addressing the framing around it, not just lubricating the track. We do that work regularly. Call (855) 382-3257 for an assessment.
Fog-belt damp and Bay salt corrode the aluminum and steel components – rollers, hinge hardware, fasteners, and door tracks – faster here than almost anywhere in California. Units within a few blocks of the ocean or Bay get it worst. Seized rollers and pitted finishes are the visible signs. Regular cleaning and hardware replacement extend the life of the unit, but when the corrosion has gone deep, replacement is the smarter spend. We’ll tell you which is which.
Yes, and it’s a common pairing here. San Francisco’s soft-story retrofit program has made garage conversions more complex but also more common, and CGI windows and doors are a solid fit for the new living space. The catch is that the garage level was never designed for living, so the rough openings are often out of square, under-flashed, or built into a wall that’s about to be stiffened. We handle the full garage conversion scope, including setting the CGI units correctly. Call (855) 382-3257 for a free estimate on the whole job.
