CGI Construction in Half Moon Bay, CA | San Bruno Construction
We provide independent CGI window and door service throughout Half Moon Bay, CA, including the 94019 ZIP code. What makes our CGI work different here is simple: we’ve spent years detailing these products against the marine layer, salt air, and wind-driven rain that define this stretch of coast. Call (866) 472-1908 to schedule a free estimate. Our crews know which CGI failures show up first in Half Moon Bay and how to fix them without pushing a full replacement when a repair is the honest answer.
Why Half Moon Bay Residents Choose Us for CGI Service
We’re not a manufacturer call center. We’re local contractors who install, strip, re-flash, and repair CGI windows and patio doors in Half Moon Bay’s coastal conditions every season. That means we know what a fogged insulated glass unit looks like on a home off Kelly Avenue in June, and we know the difference between a slider that needs new rollers and one that needs a full frame replacement. Noel Carvalho, owner at San Bruno Construction, grew up off El Camino Real in San Bruno and has spent more than two decades running residential projects across San Mateo County, including coastal work where salt corrosion is the first thing to check on any window hardware.
We’re independent CGI service providers. Not authorized, not sponsored, not warranty-backed by the manufacturer. That independence matters because it lets us tell you the truth about what’s worth fixing and what isn’t. We source OEM CGI sashes, glass, and hardware when your frame is sound, and we spec stainless or hot-dipped galvanized aftermarket fasteners and flashing when that’s what the salt air requires. And we deliver CGI sales & service with one accountable point of contact, so you’re not chasing three different vendors to fix a single window wall.

Common CGI Construction Problems We Solve in Half Moon Bay
- Fogged or failed insulated glass seals. Half Moon Bay’s marine layer keeps exterior glazing cool and damp for much of the year, so failed seals present as persistent interior condensation rather than quick overnight fogging. We replace failed IG units with OEM-compatible glass and reseal the sash correctly.
- Salt-corroded hinges, rollers, and fasteners on CGI sliders and casements. The coastal air accelerates corrosion on exposed metal, causing stiff operation and pitted hardware that inland installations never see. We strip and replace worn hardware with stainless or hot-dipped galvanized parts.
- Wind-driven rain intrusion at sill pans and rough openings. Many CGI units in Half Moon Bay were set into older wood-frame coastal walls with flashing intended for rain resistance rather than hard shedding. We re-flash openings to direct water away from the structure, not just resist it.
- Vinyl frame distortion and cracked corner welds. Years of onshore wind loading and UV exposure through fog-bright days can distort frames and crack welds at the corners, breaking the weather seal. We inspect welds carefully and tell you honestly when replacement beats patching.
- Sticking CGI sliders with condensation dripping onto sills. This combination of symptoms usually means a failed glass seal feeding moisture into a soft rough opening, plus corroded rollers grinding against the track. It’s a repair we see regularly in the fog belt.
CGI Service in Half Moon Bay: What Local Conditions Mean for Your Equipment
Half Moon Bay’s marine layer is the big differentiator. Exterior glass and metal here sit near dew point for much of the year, which means window seal failures and hardware corrosion surface as constant condensation and stiff operation, not the dry-season symptoms inland crews expect to find. On a wood-frame home off Kelly Avenue, our crew found CGI sliding windows that stuck hard and dripped condensation onto the sills, with rusty rollers and a failed glass seal feeding water into a soft rough opening. We pulled the units, re-flashed the openings to shed wind-driven rain, and set new CGI sliders with stainless rollers and hardware. The windows now glide and the sills stay dry. That’s what local knowledge gets you: a diagnosis that accounts for fog, salt, and damp wood before we touch a single fastener.
Half Moon Bay sits at the coastal edge of San Mateo County, and construction here is not like Burlingame or Millbrae. The air itself works against exposed metal. Untreated steel fasteners rust fast in the damp, salty air, and joints that would shrug off a dry-season sprinkle get tested hard by wind-driven rain. We detail every penetration to shed water away from the rough opening, and we never reuse corroded hardware when we reinstall a unit.
CGI Models & Products We Service in Half Moon Bay
Our crews work on the full range of CGI residential products common in Half Moon Bay’s housing stock, including CGI Sentinel vinyl single-hung and double-hung windows, CGI sliding glass patio doors, CGI vinyl casement and awning units, and CGI series vinyl slider windows used in coastal remodels. When a frame is sound, we source OEM replacement sashes, glass, and hardware to keep the original unit performing. When a frame is distorted or the corner welds are cracked, we tell you plainly that replacement is the better investment, and we never imply CGI covers the work. For coastal Half Moon Bay homes, we spec stainless or hot-dipped galvanized aftermarket fasteners and flashing to survive the salt air regardless of the part’s origin.
CGI Service Pricing in Half Moon Bay
What you’ll pay depends on the scope, not on guesswork.

FAQs – CGI Construction in Half Moon Bay
Constant fogging on CGI windows in Half Moon Bay usually means a failed insulated glass seal, not just humidity inside your home. The marine layer keeps exterior glazing cool and damp, so a compromised seal shows up as persistent interior condensation. The fix is replacing the failed IG unit and resealing the sash, which we handle with OEM-compatible glass. Call (866) 472-1908 for an exact quote, estimates are free.
In most cases, yes. Stiff CGI sliders along the Half Moon Bay coast typically suffer from salt-corroded rollers and hinges rather than structural frame failure. We strip and replace worn hardware with stainless or hot-dipped galvanized parts, and we check the track for pitting and grit. If the frame itself is distorted, we’ll tell you honestly and walk you through replacement options. Call (866) 472-1908 and we’ll diagnose it on site.
No. San Bruno Construction is an independent CGI service provider, not an authorized dealer, warranty station, or sponsored installer. Our independence means we diagnose and repair real failures rather than steering every job toward a factory replacement. We source OEM parts when they’re the right call and aftermarket stainless hardware when coastal conditions demand it.
Flashing on a coastal Half Moon Bay home must be detailed to shed wind-driven rain, not merely resist it. The sill pan needs positive slope to the exterior, the rough opening needs a continuous drainage path, and all penetrations need sealed, lapped flashing that directs water away from the structure. Salt air accelerates corrosion, so we spec stainless or hot-dipped galvanized fasteners for anything exposed. Call (866) 472-1908 for an inspection and quote.
Yes. A leaking CGI window in Half Moon Bay can feed water into the rough opening, rot the surrounding framing, and eventually damage adjacent wall sheathing or ceiling drywall below a roofline. If you’re seeing stains, soft drywall, or persistent dampness near a coastal window, the leak may already be spreading. Call (866) 472-1908 for a free estimate before the damage grows.
