AfterCGI Windows & Doors in San Francisco, CA | Juniper Windows & Doors
We service and repair CGI windows and doors across San Francisco, from the salt-fogged avenues of the Sunset to the sheltered slopes of Noe Valley. We’re an independent crew, not a CGI factory outlet, which means our diagnostics come from years of field work on these exact products in this exact climate. The one thing that sets our CGI work apart here? We know what the west-side salt fog does to vinyl frames and weep hardware, because we’ve fixed it hundreds of times. Call (682) 281-2168 for a free estimate on any CGI window or door that’s sticking, leaking, or off track.
Led by Sean Mackey, our team has spent years working on CGI vinyl lines across the Bay Area, and we’ve built a reputation for putting the real number on the table before a single screw turns. This page covers what actually goes wrong with CGI products in San Francisco, what it costs to fix, and why our repair-first approach usually saves you money over a full replacement. If you own CGI windows in San Francisco, this is the page that explains what’s happening to them.
Why San Francisco Residents Choose Us for CGI Service
CGI windows are built for coastal conditions, but San Francisco pushes them harder than most owners realize. The west side gets hammered by salt-heavy ocean fog and steady onshore wind for months at a time. The east side deals with sun-to-fog thermal swings that fatigue hardware in ways a hot, dry climate never would. Our CGI sales & service work across the city means we’ve seen every failure mode these units can throw at you, and we carry the parts to fix most of them same-visit.
Sean Mackey grew up in Silverlake and spent enough summers watching his uncle reframe old Craftsman windows to know he wanted to work with his hands for a living. He sharpened the technical side of that instinct at Los Angeles Trade-Technical College, focusing on construction technology and building envelope fundamentals. That’s the stuff that actually explains why a low U-factor window keeps your living room from turning into a greenhouse every July, and why a failed weep system lets fog moisture track inside your wall. He’s been doing windows and doors for well over a decade, and his rule applies to every job: “If it belongs on the page, I’ll put it there – number, timeframe, or trade-off.”
We’re an independent provider of CGI service in San Francisco, not a manufacturer warranty center. What you get instead is a crew that fixes the problem in front of us, sources OEM-equivalent parts that match CGI profiles exactly, and gives you a written price before work starts. Every job is covered by our 365-Day Done Right Promise, parts and labor, in writing.
Common CGI Windows & Doors Problems We Solve in San Francisco
- Salt-laden fog corroding vinyl frames and weep-hole hardware. West-facing elevations in the Outer Sunset and Outer Richmond bear the brunt of Pacific moisture. We regularly find corroded weep-hole inserts and frame tracks that cause sticking sashes and interior water staining. The fog isn’t just damp air around here; it’s a slow salt bath for anything exposed to it.
- CGI horizontal roller and 3-lite slider tracks packing with windblown grit. San Francisco’s constant construction dust and street grit settle into slider tracks faster than owners expect. The result is rough rolling, panels that jump the track, and tandem rollers that flat-spot and fail. We see this on 46th Avenue units just as often as on Mission Street ones.
- CGI double-hung balance springs and tilt-latch cams fatiguing from thermal cycling. San Francisco’s sun-to-fog pattern stresses metal components differently than a steady climate. Balances that hold a sash perfectly in Daly City may drop or bind here after years of daily expansion and contraction. Sash drop and mid-travel resistance are two of the most common calls we get.
- CGI casement and awning operators seizing from humidity in the gearbox. Coastal humidity infiltrates the crank mechanism, strips the spline, and suddenly the window won’t close flush against the weatherstrip. It’s a specific failure point that looks like a broken operator but often stems from a corroded internal gear.
- Weep holes blocked or mis-drilled, causing interior water staining. On San Francisco’s west side, this is the root cause of most interior water damage we’re called to inspect. The holes are either clogged with salt residue and debris, or they were drilled at the wrong angle at installation, and water backs up into the frame. Getting this wrong means water inside your wall cavity, not just on the sill.
CGI Service in San Francisco: What Local Conditions Mean for Your Equipment
Here’s the thing generic CGI pages never tell you: San Francisco’s west side gets a salt-heavy marine layer that behaves like a light industrial coating on your windows, but only on the elevations that face the ocean. The Sunset and Richmond districts sit in that fog belt for weeks at a stretch during the summer, and the onshore wind drives fine salt precipitate into framing channels, weep systems, and roller tracks. The sheltered east side around the Mission or Potrero Hill gets almost none of this; those units age like standard vinyl anywhere in the Bay Area. What that means for CGI owners is simple: if you live west of Twin Peaks and your windows face the Pacific, your weep holes and track hardware are going to demand attention years before the same window on a Bernal Heights east wall would. We’ve pulled apart enough CGI sliders near Taraval and 46th to know exactly what that salt fog does to a tandem roller set: it pits the metal, roughens the track, and eventually causes flat-spotting that makes the panel feel like it’s rolling over gravel. That’s not a generic window problem; it’s a San Francisco microclimate problem with a specific fix, and it’s the first thing we check when a west-side owner calls about a slider that’s suddenly hard to move.
CGI Models & Products We Service in San Francisco
We work on the full CGI vinyl lineup that’s common in San Francisco homes: Vinyl Single & Double Hung Windows, Horizontal Roller Windows, and the 3-Panel Sliding (3-Lite Roller) Windows you see on so many Sunset and Richmond back walls. Impact-rated units are a specialty; we understand how the laminated glass and heavy-gauge frames change the service approach. For hardware, we source OEM-equivalent CGI components from aftermarket suppliers who match the original profiles: rollers, balances, operators, vent locks, weatherstrip, and weep seals. Our service trucks carry the common parts for most CGI models, so the majority of our San Francisco calls are completed in a single visit. When a frame is cracked or a sash is rotted beyond repair, we’ll tell you honestly and help you price our Window Replacement in San Francisco rather than patch what won’t hold.
CGI Service Pricing in San Francisco
Most CGI repairs in San Francisco run between $180 and $600, depending on the hardware and the extent of the wear. Weep-hole clearing and track cleaning starts around $180 to $250. A tandem roller replacement on a 3-lite slider typically lands in the $260 to $400 range, including parts and labor. Double-hung balance and tilt-latch replacements run $200 to $350 per window. Casement operator replacements with a stripped spline repair usually cost $280 to $450. A full impact-rated CGI window replacement, when a repair genuinely won’t hold, starts around $1,400 per opening and climbs with size and installation complexity. Every estimate is free and comes as a written, line-item price before work begins, so the number we quote is the number you pay. Call (682) 281-2168 to schedule your free estimate; we’ll tell you honestly whether it’s a repair or a replacement.

FAQs – CGI Windows & Doors in San Francisco
Windblown grit and salt fog settle into the bottom track, roughening the surface and causing the tandem rollers to bind and eventually flat-spot. On west-side elevations, the salt precipitate accelerates the wear. The fix is usually replacing both roller sets and clearing the track of debris; in most San Francisco homes, this restores smooth rolling without replacing the entire window. If your slider has jumped the track more than once, the rollers are likely the culprit, not the panel. Call (682) 281-2168 and we’ll diagnose it on site.
Yes. Most drop or resistance problems come from fatigued balance springs or broken tilt-latch cams, both of which we replace with OEM-equivalent parts matched to CGI’s profile. Units on San Francisco’s fog-belt elevations wear these components faster than sheltered ones do. A double-hung that won’t stay up is dangerous and usually repairable in one visit.
Yes, and the damage is mechanical, not cosmetic. The salt content in Pacific fog deposits inside weep channels and track hardware, corroding metal parts and blocking drainage. West-facing windows in the Sunset and Richmond take the worst of it. What starts as a sticking window becomes interior water staining if the weep system fails; cleaning and reseating those channels is the first thing we do on a west-side service call.
No. We are an independent windows and doors crew serving San Francisco, and we’re not authorized by, affiliated with, or sponsored by CGI. What we bring instead is field experience on these exact product lines across the city, plus OEM-equivalent aftermarket parts that match CGI profiles. Our 365-Day Done Right Promise covers every repair we complete.
Repair is usually the right call unless the frame is cracked, the sash is rotted, or the same failure keeps repeating. Hardware replacements like rollers, balances, operators, and weeping systems cost a fraction of a full unit and extend the window’s life by years. Our Window Installation in San Francisco makes sense when the frame itself is compromised or if the glass seal has failed and the unit is out of warranty. Call (682) 281-2168 for a free inspection; we’ll tell you which route saves you money long-term.
