CGI Construction in Pacifica, CA | Milpitas Construction
We provide independent CGI window and door service across Pacifica, from full replacements on 1940s bungalows in Pedro Point to CGI repair in South San Francisco and sliding-door track rebuilds on bluff-edge homes in Rockaway. The one thing that makes our CGI work different here: we start every job at the rough opening and fasteners, because Pacifica’s salt fog eats hardware long before the glass or sash shows any wear. Call (877) 752-4194 for a free estimate from a crew that works CGI products in this fog belt every week, without any manufacturer affiliation steering the diagnosis.
Why Pacifica Residents Choose Us for CGI Service
We are not a CGI authorized dealer, and that’s deliberate. We’re an independent general contractor that installs, repairs, and replaces CGI windows and doors along the San Mateo coast, which means we answer to you, not to a product-line quota. Our CGI work covers sliding patio door systems in aluminum and vinyl frames, vinyl double-hung and single-hung window series, fiberglass entry and patio door systems, and aluminum-framed units built for coastal exposures. We carry OEM rollers, weatherstripping, glazing gaskets, and frame hardware where CGI still produces them, and we’ll tell you plainly when a corroded frame needs replacement instead of a patch job.
Ken Stafford, owner of Milpitas Construction, grew up near the Milpitas BART station when that corridor was still warehouse lots and family-owned shops, and he’s spent two-plus decades working residential builds across the Bay Area’s soil shifts and seismic quirks. His dad was a finish carpenter who kept a tidy conscience, and that’s where the no-shortcuts habit comes from. When we quote a CGI job in Pacifica, we quote it for the conditions this coast actually delivers, not for a dry inland garage.

Common CGI Construction Problems We Solve in Pacifica
- Salt-fog corrosion at aluminum frame corners and screw splines. West-facing units in Linda Mar and Rockaway show white pitting and chalky oxidation within a few seasons. The glass is usually still sound; the frame hardware is what fails first.
- Fog-driven condensation and failed perimeter seals on vinyl units. When interior and exterior sealing was done for inland conditions, wind-driven moisture gets into the rough opening and rots the framing around the window. We see this constantly on 1950s stucco homes near the bluffs.
- Roller and track failure on CGI sliding patio doors. Salt grit and sand carried onshore off Rockaway and Linda Mar pack into the bottom track, grind the rollers flat, and turn a smooth door into a two-hand shoulder shove.
- Galvanized fasteners and flashing corroding before the unit does. A door installed with big-box electroplated screws will shed them within a few seasons of Pacifica fog. The CGI unit can be fine while the hardware holding it is powder. We replace with corrosion-rated materials.
- Fog-belt rot around window sills and exterior trim. Persistent marine layer moisture keeps wood and stucco sills damp nine months a year. By the time the window shows sticking or the drywall inside gets soft, the rough opening usually needs real carpentry, not just caulk.
CGI Service in Pacifica: What Local Conditions Mean for Your Equipment
Pacifica’s salt fog attacks door and window hardware faster than the units themselves. Frame screws, hinges, and flashing that would last decades with CGI service in San Bruno or Millbrae are already failing here within a few years. That means a CGI replacement or repair job on the coast usually starts with inspecting the rough opening and fasteners, not the sash. On a Linda Mar job, our crew pulled a set of CGI sliding patio doors whose tracks were packed with salt grit and whose frame corners had pitted white, while the glass and sashes were still sound. We replaced the OEM rollers and weatherstripping, re-flashed the sill with corrosion-rated materials, and resealed the perimeter for fog-belt moisture. The doors now slide clean and the homeowner avoided a full unit swap. Out of 94044, this is standard procedure; it is not optional.
CGI Models & Products We Service in Pacifica
Our crew works on the full CGI roster that shows up in Pacifica homes: aluminum and vinyl sliding patio door systems, vinyl double-hung and single-hung window series, fiberglass entry and patio door systems, and aluminum-framed window and door units spec’d for coastal exposure. For repairs, we use OEM CGI parts for rollers, weatherstripping, glazing gaskets, and frame hardware wherever they’re still in production. When OEM is discontinued or back-ordered, we’ll tell you and offer a quality aftermarket equivalent, never a cheap substitute that salts out in a year. If you’re planning a broader remodel, our CGI sales & service page covers the full scope of what we handle. For window replacement and impact window installation along the coast, we stock common CGI frame hardware locally so a Pacifica visit does not stall on a parts order from back east.

FAQs – CGI Construction in Pacifica
Because salt grit and sand from the onshore wind get into the bottom track, pack around the rollers, and destroy them within a few seasons. The door itself is usually fine. We clean the track, replace the OEM rollers and weatherstripping, and adjust the alignment so the door slides clean again. Call (877) 752-4194 if yours is binding.
It shortens the hardware life dramatically, especially on west-facing exposures. Aluminum frame corners pit white, galvanized screws corrode to dust, and perimeter seals fail from constant damp. It is not a warranty issue, it is an environment issue. Coastal-grade installation is what buys you time. We do that.
If the pitting is cosmetic and the frame is structurally sound, we can clean it, treat it, and reseal the corners to slow further corrosion. If the screw splines or corner joints have lost structural integrity, the unit gets replaced. We’ll show you which one you have before you spend a dollar.
Window and door replacement typically does not trigger a geotechnical review, but any addition, deck work, or structural change on Pedro Point bluff-edge properties often does. If the project moves beyond swapping the unit in the existing rough opening, we’ll flag that before pulling permits. Call (877) 752-4194 and we’ll tell you which path applies to your house.
Yes. We handle the flashing, the rough opening rebuild, and the surrounding roof edge as part of the same contract. On Pacifica homes where salt fog is already chewing through the roof flashing, leaving that work to a separate trade just stacks callbacks. One crew, one accountable fix.
