CGI Construction in Moss Beach, CA | Milpitas Construction
We provide independent CGI window and door service across Moss Beach, from replacement sashes and rollers to full impact-window and roof-scope installations on bluff-edge lots. The difference here is the salt. Moss Beach sits on a foggy marine terrace where west-facing CGI aluminum gets pitted and corroded within a few winters unless every fastener, flashing detail, and drainage plane is spec’d for coastal exposure. Call Milpitas Construction at (877) 752-4194 for a free estimate on CGI work that actually holds up out here. We’re an independent CGI service provider, not manufacturer-authorized or affiliated, and we say so plainly.
We also carry full-service CGI sales & service expertise across the Bay Area, and we’ve spent years working the coastal San Mateo County corridor from Pacifica down through Half Moon Bay.
Why Moss Beach Residents Choose Us for CGI Service
Most window crews in this area are inland generalists who don’t think about what salt fog does to aluminum. Our work in Moss Beach starts with the assumption that every exposed surface takes direct Pacific weather for about 200 days a year. We spec marine-grade stainless fasteners, we flash openings with actual drainage planes, and we read CGI’s published installation literature before we touch a single unit. Then we adapt it. A standard CGI install detail written for a Sacramento tract home will fail within two winters on a beach cottage off Highway 1, and that’s not a knock on CGI. It’s a reality of building on a marine terrace.
Ken Stafford grew up around Milpitas when that corridor was still warehouse lots and family-owned shops, and he got his construction foundation at Evergreen Valley College. The habit of doing work you’re not embarrassed to stand behind comes from his dad, a finish carpenter who kept a tidy garage and an even tidier conscience. That’s the standard we bring to every Moss Beach job: no shortcuts, no callbacks, no flash details that quietly rot a wall behind the siding. Build it right the first time – the Bay Area doesn’t give you a free pass on shortcuts.

Common CGI Construction Problems We Solve in Moss Beach
- Salt pitting and white corrosion on aluminum frames. West-facing CGI Series 200 and 300 sliders within a mile of the surf line start showing pitting on the frame corners and hinge edges after just two or three winters. We replace affected hardware with marine-grade stainless and treat the extrusion where it’s still structurally sound before recommending full unit replacement.
- Fog-driven condensation and interior finish failures. When a CGI unit gets flashed directly against wood siding without a drainage plane, the daily fog condenses inside the wall and the interior trim shows water staining within a season. We’ve fixed this exact failure on Moss Beach cottages and bluff homes, rebuilding rough openings with sill pans and an actual weep path so the water leaves the wall instead of pooling.
- Rust-jacked sill and jamb anchors from wrong fasteners. Earlier crews love standard galvanized screws. In Moss Beach that means rust jacking at the sill within a few winters, cracked stucco, and a window that slowly loosens out of its opening. We pull the old anchors, install stainless, and re-flash the opening properly.
- Sliding-door track corrosion and roller failure. Grade-level slider doors on beach cottages get wind-blown sand and salt packed into the track. Rollers wear out, the door gets heavy, and then the track itself starts corroding. We replace rollers with upgraded marine-grade parts and rebuild the track bed when it’s still viable.
- Undersized flashing on bluff-top remodels. Wind-driven winter rain off the Pacific hits windows at a different angle than inland rain patterns, and a standard head flashing will let water drive behind the top flange. On bluff-edge lots above the beach we install deeper head flashing and positive drainage details that actually handle driven rain.
CGI Service in Moss Beach: What Local Conditions Mean for Your Equipment
Here’s the part inland CGI pages never mention. Moss Beach has no city building department. Every window and door replacement routes through San Mateo County permitting, and on bluff-edge lots county coastal-development and geotechnical review can attach conditions to your openings that change the wind-load spec and anchoring requirements before a single CGI unit gets ordered. We saw this directly on a mid-century beach cottage off Highway 1: the original CGI aluminum sliders had corroded rollers and a sill flashed straight onto the siding with no drainage plane, so fog-driven rain was pooling inside the wall. We pulled the units, rebuilt the rough opening with a proper sill pan and marine-grade stainless anchors, and reset new CGI sliders with a drained flashing detail. The interior wall stayed dry through the first winter storms. That’s the service level Moss Beach demands, because between the salt fog and the county’s coastal-review process, the cheapest bid is rarely the one that doesn’t cost you twice.
If you’re on a bluff-edge lot above the Fitzgerald Marine Reserve side, expect county staff to ask about geotech and bluff setback before they stamp your permit. We’ve done enough County of San Mateo coastal submittals to know which details trigger review and which ones pass clean the first time. That alone can save a Moss Beach owner six to ten weeks.
CGI Models & Products We Service in Moss Beach
We work on CGI aluminum series windows and doors, including Series 200, 300, 400, and 500 sliding and casement lines, plus the CGI Elite and Elite 9000-series vinyl windows, custom aluminum storefront and multi-slide door systems for coastal view openings, and awning and fixed-picture units commonly specified on bluff-top remodels. Where a unit is still supported, we source genuine CGI replacement sashes, hardware, rollers, and weatherstrip. When an OEM part is discontinued or undersized for salt exposure, we use quality aftermarket marine-grade stainless hardware. We keep common CGI roller sets, weatherstrip profiles, and hardware kits on our trucks so most Moss Beach service visits happen in one trip instead of two.
One thing we don’t do is sell a full replacement when the frame is still sound. If the aluminum extrusion isn’t corroded through, we repair and re-flash. Replacement makes sense only when the frame itself is gone or the opening needs redesign for a new coastal wind-load spec.

FAQs – CGI Construction in Moss Beach
Yes. Moss Beach falls under San Mateo County permitting, and on bluff-edge lots any window or door replacement can trigger coastal-development review, geotech conditions, and revised wind-load anchoring requirements before work starts. We handle the submittal and the correspondence so you don’t get stuck reading county comment letters blind.
Persistent salt fog and wind-driven rain off the Pacific causes accelerated pitting and white corrosion on untreated or underspecified aluminum, especially on west-facing units within a mile of the surf line. We’ll assess whether the frame is still structurally viable, then either treat it, upgrade the hardware to marine-grade stainless, or quote full replacement if the extrusion is corroded through. Call (877) 752-4194 for a free look.
Yes, if the frame is sound and the failure is limited to rollers, track wear, weatherstrip, or anchors. We rebuild, re-flash, and reset the same door with marine-grade stainless hardware when possible. Replacement only makes sense when the frame is corroded through or the opening needs a new coastal wind-load design.
Daily fog condenses inside any wall where the window lacks a proper drainage plane, and wind-driven rain can blow behind the top flange if head flashing is too shallow. We install sill pans, positive weep paths, and deeper head flashing on every Moss Beach opening – details that inland crews skip and that inland homes don’t need.
Often, yes. Moss Beach has a large stock of mid-century and older beach cottages, and we regularly find aging framing, dry rot at sills, and undersized headers that won’t meet current coastal and seismic codes once we expose the rough opening. We’ll give you an honest assessment before any new CGI unit goes in, not after. Call (877) 752-4194 for an exact quote – estimates are free.
