CGI Construction in Half Moon Bay, CA | Seaside Contractors
We provide independent CGI construction and finishing service across Half Moon Bay, from quartz countertop slab installs to standing seam metal roofing built for the fog belt. The thing that separates our CGI work here is simple: we detail every exterior and moisture-exposed component for salt air and wind-driven rain, because we’ve seen what happens to coastal assemblies that aren’t. If you’re planning a kitchen, bath, or roof project with CGI materials, call (833) 589-8103 before you sign anything.
We’re not manufacturer-affiliated or authorized by CGI. We’re a full-scope general contractor that has worked with their countertop, cabinetry, glass, and metal roofing lines on San Mateo County coast projects for years. That independence means we’ll tell you when a CGI line is right for your Half Moon Bay home, and when another material on our truck fits better. One contractor, every trade. From Half Moon Bay service area coastal cottages to bluff-side custom builds, we handle the full scope.
Why Half Moon Bay Residents Choose Us for CGI Service
CGI makes a broad range of products, and most contractors in Half Moon Bay know maybe one or two of their lines. We work across their quartz and natural-stone countertop programs, frameless glass shower hardware, cabinetry, and standing seam metal roofing, which means we can spec CGI where it makes sense and swap to a better-suited material where it doesn’t. Glen Sorrento grew up on the Peninsula and studied building construction technology at College of San Mateo before spending two-plus decades on nearly every project type the coast throws at a builder. He’s the one who walks your job and gives you the straight answer on whether a CGI slab is worth the upsell for your specific kitchen.
We maintain OEM CGI components for the fit-and-warranty items: glass clamps, panel clips, cabinet hardware. For commodity fasteners and sealants, we upgrade to stainless or hot-dip in the marine zone, which is standard practice for us but rare enough among inland crews that we’ve made a lot of repair money fixing their work. Half Moon Bay homeowners call us because they want one accountable team that knows CGI materials and knows what salt air does to them.

Common CGI Construction Problems We Solve in Half Moon Bay
- Quartz countertop seams and sink cut-outs wicking moisture. In fog-belt kitchens, standard adhesive lets moisture creep into the seam and wick up through the sink rim. The edge dulls and discolors long before the field surface shows anything. We cut and set rims with sealed edges and marine-grade adhesive, then test every seam before the backsplash goes in.
- Frameless glass shower hinges and clamps pitting and seizing. Chrome or standard-plated hardware in a salt-air bathroom near the water starts pitting within a few seasons. The hinge seizes, the clamp corrodes, and the door eventually sags. We substitute stainless hardware on every glass enclosure we install in Half Moon Bay. No exception.
- Cabinet boxes and toe-kicks swelling at the bottom edge. Coastal kitchens with slab-on-grade floors pull moisture up through the concrete, and cabinets set tight to the slab wick it into the toe-kick. The box delaminates, the doors stop aligning. We install a vapor break under every cabinet run and leave the bottom edge off the slab where the floor system allows.
- Standing seam metal roof panel cut-edge and fastener corrosion. On bluff-side homes, wind-driven rain and salt spray find every exposed cut edge and every standard fastener. We detail flashing for the marine zone, use stainless fasteners throughout, and hem exposed cut edges rather than leaving raw metal for the fog to eat.
- Improper coastal-permit sequencing. Exterior CGI work on bluff homes often needs a Coastal Development Permit before the city will even look at building plans. We sequence material orders and interior template work around the permit calendar so you’re not paying for cabinets sitting in a warehouse while the coastal commission reviews your re-roof.
CGI Service in Half Moon Bay: What Local Conditions Mean for Your Equipment
Half Moon Bay sits in a foggy, salt-laden coastal zone where construction must be engineered for moisture and marine air. Decay-resistant framing, stainless or hot-dip fasteners, corrosion-rated flashing, and continuous wind-driven-rain detailing are the baseline here, not upgrades. The same job 20 minutes inland over the hill in San Mateo or Redwood City is built to a completely different durability standard. That gap is where most CGI installation failures on the coast begin.
Here’s the specific thing about Half Moon Bay that shapes how we work: projects on bluffs and exposed hillsides often need a Coastal Development Permit on top of city building review. An exterior change like a standing seam metal roof or a re-sided wall can sit in that coastal-permit queue for months. We sequence material orders and cabinet and countertop templates around the permit calendar, not the other way around. A contractor who orders the metal roof panels before the permit clears is paying storage fees and watching the material sit in a yard while the coastal commission works through its backlog. We’ve run enough jobs here to know the rhythm.
CGI Models & Products We Service in Half Moon Bay
We work across CGI’s quartz and natural-stone countertop surfaces for kitchen and bath slab programs, their frameless glass shower enclosures and hardware, their cabinetry lines for kitchen and vanity installations, and their standing seam metal roofing systems. For repairs and replacements, we use OEM CGI components where warranty and fit depend on it: glass hinges, panel clips, cabinet hardware. For commodity items like fasteners and sealants, we use quality aftermarket products, always upgrading to stainless or hot-dip grade in the marine zone. We keep a rotating local stock of common CGI hardware so we’re not waiting on a distributor truck from the East Bay when your shower door needs a clamp swapped this week.

FAQs – CGI Construction in Half Moon Bay
Yes, if they’re installed correctly for the moisture level. The slab itself is non-porous and doesn’t absorb fog, but the seams and sink cut-outs will wick moisture if set with standard adhesive and left unsealed. We detail every edge and rim for marine exposure, and the countertop will hold up as well as it would inland. Call (833) 589-8103 to have us look at your existing slab or spec a new one.
Most bluff-side and exposed-hillside homes in Half Moon Bay do, yes. The Coastal Commission overlay applies to significant exterior changes, and the review can add months. We handle the permit sequencing and build material orders around it so you’re not paying for a roof that’s waiting on paperwork. Call (833) 589-8103 and we’ll tell you what your specific address triggers.
Salt air. Chrome and standard zinc-plated hinges and clamps pit and seize within a few seasons of marine exposure. We install stainless hardware on every glass enclosure in Half Moon Bay, which costs slightly more up front and lasts decades longer. If your existing hardware is already pitting, we can swap it before the door sags and stresses the glass.
It can be, when the cut edges and fasteners are detailed for wind-driven rain and salt spray. The panel system itself performs well, but the difference between a roof that lasts 40 years and one that starts corroding at year five is all in the detailing. We’ve re-flashed and corrected enough poorly installed metal roofs on the bluffs to know exactly where the first failures show up.
If the moisture has reached the box structure and the bottom edge is delaminating, replace. A patch on a swollen toe-kick fails again because the moisture source hasn’t stopped. We reset new cabinets on a vapor break and detail the bottom edge for the slab condition, which fixes the problem rather than hiding it. Call (833) 589-8103 for a straight answer on your specific cabinets.
