CGI Construction in San Francisco, CA | Elmstead Remodeling San Francisco
We provide independent CGI window and door service across San Francisco, from the Sunset District to the Mission, with no manufacturer ties. What makes our CGI work different here is that we’ve spent years repairing and installing these units in buildings shaped by the city’s soft-story retrofit mandates and salt-heavy fog, so we know which models hold up and which need attention before the next inspection. Call (831) 480-4497 for a free estimate on any CGI repair or replacement in San Francisco, and we’ll give you a written price before any work starts.
Why San Francisco Residents Choose Us for CGI Service
We’ve worked on CGI windows and doors throughout San Francisco for years, and that local time matters. Our techs can tell you within the first few minutes whether a stiff Estate Collection casement just needs hardware lubrication or whether the aluminum frame has started pitting from decades of salt air off Ocean Beach. Graham Stein, owner of Elmstead Remodeling San Francisco and a General Contractor in San Francisco, learned the trade at Los Angeles Trade-Technical College and has spent nearly three decades swinging a hammer and managing crews across California. He writes out every cost before a single tool touches the floor, and he sets quiet hours so families aren’t chased out of their own homes during a window replacement. We use genuine CGI parts for critical components like locking mechanisms and weatherstripping, because fit and finish matter when a window needs to seal against San Francisco fog. For non-structural pieces like glazing beads or interior trim, quality aftermarket equivalents often perform just as well, and we’ll tell you which is which and why.

Common CGI Construction Problems We Solve in San Francisco
- Corrosion and pitting on aluminum frames in foggy coastal districts. The Sunset and Richmond see more salt air and damp fog than almost any other part of San Francisco, and older Sentinel Series units are the ones we most often find with frame corrosion that compromises the seal. We’ll assess whether the frame is salvageable or whether a new impact-rated unit is the better long-term call.
- Failed or stiff operating hardware on Estate Collection casements. Salt air exposure without regular lubrication seizes hinges and operators over time. We stock replacement hardware for the most common Estate Collection configurations, so turnaround in San Francisco is often days, not weeks.
- IGU seal failure showing interior fogging or mineral deposits between panes. We see this most often in homes with single-pane retrofits where interior humidity runs high, and the temperature difference between a fog-cooled exterior and a heated interior stresses the seal. A failed IGU is usually repairable without replacing the entire window, and we’ll price it both ways.
- Warped or misaligned sashes on Targa Series sliders. Pre-1940 wood-frame buildings settle, and the sliders that worked fine in 1990 can bind or drag after decades of that movement. We realign, adjust rollers, and replace tracks where needed, and we’ll tell you honestly if the frame has moved enough that a new install makes more sense.
- Weatherstripping failures on windows facing the prevailing wind. In San Francisco, the west-facing elevations take the brunt of the marine layer. When weatherstripping wears out, you get drafts, fog intrusion, and higher heating bills. We replace it with genuine CGI weatherstripping to restore the original seal.
CGI Service in San Francisco: What Local Conditions Mean for Your Equipment
Here’s a fact that doesn’t apply in Daly City, Oakland, or anywhere else across the bay: San Francisco’s mandatory Soft Story Retrofit Ordinance, Ordinance 66-13, requires seismic upgrades for thousands of wood-frame buildings with ground-floor garages or storefronts. Many of those buildings also need window and door replacements to accommodate the new shear walls and moment frames that the retrofit demands. So we regularly coordinate with structural engineers to make sure new CGI units don’t conflict with the structural work, and that the finished openings match what the building department will sign off on. In neighborhoods like the Marina and Mission, where soft-story ground floors are common, this code-driven demand means CGI window work here is often tied to a larger seismic project, and the sequencing matters. We help clients plan so the windows don’t get ordered too early or installed too late relative to the structural retrofit.
CGI Models & Products We Service in San Francisco
We work on the full CGI residential and commercial lineup: the Estate Collection, Sentinel Series, Targa Series, and CGI Commercial Series. For critical parts, we order genuine CGI components so locking mechanisms and weatherstripping match exactly. For non-structural items like glazing beads and interior trim, we’ll offer aftermarket options where they make sense and tell you the cost difference in writing. We keep common hardware and weatherstripping for the most frequent San Francisco failures stocked locally, which shortens turnaround on repairs across the city. If you’re looking for broader CGI sales & service context, that page covers the full picture, but here we focus on what actually fails in San Francisco’s climate and housing stock.

AfterCGI Service Pricing in San Francisco
What drives the cost on CGI work in San Francisco depends on three things: the condition of the frame, whether the building is mid-retrofit or already retrofitted, and whether we’re working on a third-floor window in a Marina District walk-up or a ground-floor unit with easy access. Here are the ranges we see most often:
| Service | Typical San Francisco Price Range |
|---|---|
| Impact Window Installation | $9,440 – $29,500 |

FAQs – CGI Construction in San Francisco
Yes. New CGI units with Low-E glass and thermal breaks meet or exceed Title 24 requirements for replacement windows in San Francisco. We verify code compliance on every installation, and we’ll flag any additional requirements that apply to your specific building, especially if it’s part of a soft-story retrofit where the building department is reviewing the whole envelope. Call (831) 480-4497 if you want us to check your specific situation.
In most cases we can replace just the IGU, or insulated glass unit, without replacing the entire sash, as long as the frame and operating hardware are still sound. We’ll quote it both ways so you can see the numbers. If the frame has corrosion from salt air or the hardware is failing, a new sash or full window may be the less expensive option over five years. Call (831) 480-4497 and we’ll come look.
No, impact windows are not automatically required by the Soft Story Retrofit Ordinance. The ordinance addresses structural conditions like soft-story ground floors, not window specifications. However, many clients choose impact-rated windows when replacing them during a retrofit, because the building is already open and the incremental cost buys windborne-debris protection in a city with coastal high winds. We’ll walk you through the options and what your structural engineer recommends.
Aluminum-framed CGI windows, especially the newer thermal-break models, generally resist corrosion better than untreated aluminum, but they still need maintenance in the Salt Air districts like the Sunset and Richmond. Vinyl windows don’t corrode, but they typically lack the structural rigidity that San Francisco’s seismic environment rewards. Our honest take: in a pre-1940 wood-frame building that’s settling, a well-maintained CGI aluminum unit often outperforms vinyl over the long term, provided the hardware is lubricated and the weatherstripping replaced on schedule. Call (831) 480-4497 and we’ll assess your specific elevations.
We service and repair CGI windows regardless of who installed them. Our own work carries the 365-Day Done Right Promise: if it’s not done right after the job is complete, we make it right. For units installed by others, we’ll diagnose the problem, tell you what’s covered under any remaining manufacturer warranty, and quote the repair or replacement honestly.
