CGI Construction in Colma, CA | Daly City Construction
We provide independent CGI service across Colma’s 94015 ZIP, from residential window replacements on the few blocks of housing here to serious door and glazing work on cemetery support buildings. The thing that separates our CGI work in Colma from anywhere else is that we plan every job around what’s underground before we touch what’s above it. Plot maps, old vaults, undocumented graves. You don’t open a trench near a chapel foundation without checking first. Call (866) 505-5254 for a free estimate on any CGI door, window, or patio system in Colma.
Why Colma Residents Choose Us for CGI Service
We work on CGI doors and windows constantly across Daly City, Colma, and South San Francisco, so we know how these products actually fail in coastal fog and damp soil rather than how a brochure says they should perform. Condensation at aluminum sills, corrosion at the bottom rail of a steel entry door, fogged dual-pane units from the temperature swings that ride in off the Pacific. That’s the real-world stuff.
Noel Cabrera, our owner, grew up in Daly City’s Westlake district and trained in construction technology at City College of San Francisco before putting in years of hands-on residential and light commercial work across San Mateo and San Francisco counties. He’s spent enough time on Colma jobs where the fog never fully burns off to know that moisture detailing matters more than anything else on a door or window opening here.
We’re an independent contractor. We are not authorized, sponsored, or endorsed by CGI. What we bring instead is field experience, documented workmanship, and a parts approach that favors OEM CGI hardware and glazing when a unit is still serviceable and honest replacement advice when it isn’t.

Common CGI Construction Problems We Solve in Colma
- Fog-belt condensation and water infiltration at CGI aluminum window frames and sills. Colma sits in the fog belt just inland of Daly City, and that persistent damp shows up as interior staining and failed perimeter seals on older 94015 homes. We reset openings with new flashing and sealed thresholds instead of just caulking over the damage, which is what actually holds here.
- Corrosion and finish breakdown on CGI steel entry doors. Year-round damp plus salt-laden coastal air attacks the bottom rail and hinge-side edges first. We see this on residential doors and on mortuary support buildings alike. When the frame is still solid, we repair. When the corrosion has eaten into the structural steel, we say so and recommend replacement.
- Roller and track failure on CGI sliding patio doors. Moisture exposure and grit intrusion eventually bind the rollers and make the door hard to latch. On Colma streets where fog sits until mid-afternoon, the rollers take on that grit and humidity cycle repeatedly. We clean, replace, and realign tracks and swap in quality aftermarket rollers where OEM units are no longer available.
- Thermal seal failure in CGI dual-pane units. The coastal temperature swing stresses the spacer and desiccant inside sealed glass, and that’s how you get fogging between panes that won’t wipe off. We source OEM glazing components when the sash is still serviceable. Once the seal is gone throughout, replacement glazing is the fix.
- Perimeter water intrusion around CGI door and window openings on cemetery-adjacent structures. When the soil around a chapel or mortuary building stays saturated through most of the year, any gap at the sill or threshold pulls moisture inward. We address the flashing and drainage at the opening, not just the visible leak line.
CGI Service in Colma: What Local Conditions Mean for Your Equipment
Here’s what makes Colma genuinely different from any neighboring city, and why it matters for CGI door and window work. Colma’s cemeteries hold more than 1.5 million burials across roughly 17 cemeteries, meaning the dead outnumber the living here by about a thousand to one. Every excavation, including trenching to run utilities or regrade the ground around a chapel or mortuary building, has to be cleared against individual cemetery plot maps, not just city records. Undocumented graves and old vaults sit under what looks like open ground. That changes how we plan any site work near CGI door and window openings on cemetery-adjacent structures. We can’t assume a clean dig, so we sequence the job differently: verify the plot maps and easements first, then open the ground carefully, then do the window or door work. On a chapel utility upgrade near the Colma border with Daly City, we replaced fogged CGI dual-pane windows and a corroded CGI steel entry door on a small mortuary support building. We found perimeter water infiltration at the aluminum sills from years of fog-belt condensation, reset the openings with new flashing and sealed thresholds, and swapped the failed door hardware. The building stayed dry through the wet season, and the cemetery operator had our crew document the work against their plot map before we backfilled the utility trench.
CGI Models & Products We Service in Colma
We service CGI residential entry and interior door series in both steel and fiberglass, CGI aluminum and vinyl window lines including single-hung, sliding, and fixed units, CGI sliding patio door systems, and CGI storm and security screen and door products. The parts call is straightforward: OEM CGI hardware and glazing components when the unit is repairable and the assembly still has life in it, and proven aftermarket weatherstripping, rollers, and thresholds where OEM parts are discontinued or priced beyond reason. We stock the common wear items that give out in fog-belt conditions, so a roller or seal replacement on a Colma sliding patio door doesn’t mean a two-week parts wait. When frame corrosion or seal failure is extensive, we tell owners directly that replacement is the smarter investment than chasing a repair that won’t survive this climate. We don’t push replacement when a repair is honest work, and we don’t sell a patch job when the unit is already done.

AfterCGI Service Pricing in Colma
CGI-related pricing in Colma depends on what’s actually failing and whether the opening needs structural work around the door or window. Here’s how typical scopes land:
| Service | Price Range |
|---|---|
| Window Replacement | $4500 – $15000 |
| Impact Window Installation | $8000 – $25000 |
| Roof Repair | $400 – $1800 |
Roof repair enters the picture more often in Colma than people expect, because water getting past a failed roof edge or parapet is frequently what’s actually feeding the moisture problem at a CGI window or door below. We’ll look at the whole opening, including what’s above it, before we quote. Every estimate is free and line-itemed, so you know what’s parts, what’s labor, and what’s site work like plot-map verification or flashing replacement. Call (866) 505-5254 and we’ll put a number on it.

FAQs – CGI Construction in Colma
Yes. The burial records don’t move, and the plots stay where they are. What changes is the sequence of work: we coordinate with the cemetery operator and their plot maps before any excavation or ground disturbance, then set the new CGI windows from the exterior or interior without trenching near grave sites. We’ve done exactly this on chapel and mortuary support buildings in Colma, and the operators appreciate that we document everything before backfilling. Call (866) 505-5254 if you manage a cemetery building with failed glazing, and we’ll walk the site with you first.
Colma’s persistent coastal fog and damp year-round air put constant moisture against aluminum frames and sills, which eventually compromises the perimeter seals and lets condensation work inward. The dual-pane seal itself fails when temperature swings between fog-cool mornings and warmer afternoons stress the spacer and desiccant. It’s not a manufacturing defect, it’s the climate here. We address it by resetting the opening with proper flashing and drainage, not just by recaulking the sills, because recaulking alone fails again in a season or two. Call (866) 505-5254 for a free estimate on resealing or replacing fogged CGI units.
It depends on where the corrosion is. Bottom rail and hinge-side surface rust on an otherwise sound steel door is repairable with proper prep, treatment, and resealing. But when rust has eaten into the structural steel at the corners or around the lock and hinge reinforcements, the door is no longer doing its job, and replacement is the honest call. In Colma’s damp, salt-laden air, we lean toward replacement earlier than we would in an inland city, because a repair that’s marginal in dry air fails faster here. We’ll show you the corrosion and tell you straight what it needs.
For like-for-like window and door replacement in existing openings, Colma typically does not require a building permit, unless the opening size changes structurally or the building sits on cemetery-adjacent property with its own easement conditions. Any work that involves ground disturbance, trenching, or structural changes does trigger review and coordination with the city and possibly the cemetery operator. We handle permit pulls and coordinate plot-map clearance when a job requires it. Permit work is part of the scope, not an afterthought.
The fog belt means two things for a sliding patio door in Colma: constant moisture on the track and rollers, and grit that gets tracked in when things dry out. The combination binds rollers, grinds tracks, and makes latching hard. Regular roller replacement and track cleaning, along with good threshold sealing, keep the door sliding without binding. We stock common CGI-compatible roller sets specifically because we replace them so often on Colma and Pacifica doors. Call (866) 505-5254 for a free estimate on getting your sliding door moving again.
