CGI Construction in Portola Valley, CA | San Mateo Construction
We provide independent CGI cabinetry and countertop service across Portola Valley, from full kitchen remodels to single-box repairs and refacing. We’re not a CGI dealer or factory agent, so our recommendations come from what we’ve watched hold up or fail on multi-acre wooded lots, not from a brand program. If you’re dealing with swollen frameless boxes, sagging soft-close hinges, or a countertop seam that’s opened up on a hillside foundation, call us at (855) 901-7266 and we’ll tell you straight what’s worth fixing and what isn’t.
Why Portola Valley Residents Choose Us for CGI Service
Most contractors in Portola Valley know the town’s building department and its WUI requirements. Fewer know CGI’s Euro-style frameless cabinets well enough to tell you why a door face is delaminating at the toe-kick, or whether an aftermarket glide will outlast the factory one on a west-facing wall. We do both. Noel Carrington, our owner, spent decades working residential jobs across San Mateo County, including our Stanford CGI service, and his background shows in the way we approach a CGI kitchen: we check the subfloor, the ventilation, and the wall squareness before we touch a box, because those are the things that determine whether the cabinets will stay true five years from now.
When a CGI panel doesn’t fit a hillside house with out-of-square walls, we fix it on site. We don’t route you to a manufacturer call center, and we don’t pretend a warranty claim will solve a drainage problem.

Common CGI Construction Problems We Solve in Portola Valley
- Swollen and delaminated door faces on frameless boxes. We see this constantly in Portola Valley kitchens that sit over hillside crawlspaces. Seasonal moisture migrates up through sloped, under-drained foundations, and the bottom edges of CGI doors take the hit first. We fix the drainage and ventilation before we replace or reface anything, or you’ll be back in the same spot in two years.
- Sagging soft-close hinges and drawer glides. The thermal swings here are real: dry Diablo-wind summers followed by cool, foggy nights. On west-facing walls with large glass, those temperature cycles work CGI hardware loose. We re-adjust or swap in quality aftermarket glides where the factory parts are discontinued.
- Chalking and hairline-cracking on painted CGI finishes. Full afternoon sun through unshaded south-facing glazing bakes exposed island panels and end gables. Tree-thinned lots make it worse. We match the finish and refinish or replace the affected panels, and we’ll tell you honestly whether the orientation of the room is going to beat the finish again.
- Countertop seams and sink cutouts opening up. On hillside foundations with minor seasonal movement, CGI quartz seams can separate just enough to catch a fingernail. This is a foundation issue first and a countertop issue second. We check what’s moving before we re-set the top.
- Out-of-square cabinet runs on custom homes. Portola Valley has a lot of architect-designed rebuilds and additions where nothing is perfectly plumb. Frameless CGI boxes are less forgiving than face-frame cabinets. We scribe, shim, and adjust on site rather than forcing a bad fit.
CGI Service in Portola Valley: What Local Conditions Mean for Your Equipment
Here’s what most cabinet pages won’t tell you: most of Portola Valley is mapped wildland-urban interface, which means even an interior kitchen remodel can trigger WUI-related review at the town level. We’ve seen cabinet and countertop plans get revised after geological and hillside reports come back, long before a single CGI box gets ordered. Add the narrow private lanes with weight limits that can’t take a full-size concrete truck, and you start to understand why Portola Valley projects run on a different clock than a flat Peninsula job. On a wooded lot off a narrow lane where we provide our Ladera CGI service, we tore out a 1990s kitchen and found the CGI frameless boxes along the exterior wall had swollen at the toe-kick from crawlspace moisture wicking up a sloped, under-drained foundation. We corrected the subfloor and ventilation first, then set new CGI shaker cabinets on a level, sealed base with aftermarket soft-close glides and a quartz top. The delivery came in a smaller truck because the lane couldn’t take a full-size hauler. That’s the job, and if you’ve lived here long, you already know it.
CGI Models & Products We Service in Portola Valley
We work on CGI’s Euro-style frameless cabinetry, including full-overlay doors with soft-close hardware and integrated handle profiles, plus their shaker and raised-panel collections in painted and stained finishes. We also service CGI quartz and granite countertop programs and their floating and furniture-style bath vanities. For parts, we use genuine CGI hardware and touch-up materials where they’re still available, and we switch to quality aftermarket hinges, glides, and fillers when a discontinued CGI profile or finish means a factory part can’t be matched. Most common hardware is on our truck, which keeps turnaround tight for Portola Valley jobs. For broader context, see our CGI sales & service page.

FAQs – CGI Construction in Portola Valley
Yes, it can. Because much of Portola Valley is mapped wildland-urban interface, the town’s planning review sometimes flags interior projects for WUI-related conditions, especially if the work touches an exterior wall, ventilation, or the building envelope. We’ve had cabinet layouts revised after review comments came back. The earlier we check the scope against the town’s requirements, the fewer surprises. Call (855) 901-7266 and we’ll walk through what your specific project is likely to trigger.
In our experience, the moisture is almost always coming from below: a sloped, under-drained crawlspace wicking water up through the foundation and into the toe-kick and lower door edges. Replacing the boxes won’t fix it. We correct the drainage and ventilation first, then set the new or refaced cabinets on a sealed, level base. On lots where we handle CGI service in West Menlo Park, this is the failure we see most.
Often not in Portola Valley. Many private lanes have weight limits and tight turns that rule out a full-size hauler or concrete truck. We stage deliveries in smaller vehicles and coordinate pours accordingly. It’s part of planning any Portola Valley job, and we account for it in the schedule and the quote.
They can, especially if the project touches a foundation, slab, or exterior wall on a sloped lot. The town’s reporting requirements sometimes come back with findings that revise cabinet or countertop plans before a single CGI box is ordered. We build that buffer into the timeline from the start—just as we do for our CGI in Los Altos Hills—so the delay doesn’t blindside you.
If the carcasses are sound, yes. We’ll reface or replace individual boxes and doors, and we’ll match the finish. But on a moisture-damaged hillside kitchen, we’ll tell you honestly when a full re-box is the cheaper long-run call. A reface over a compromised box is money you’ll spend twice. Call (855) 901-7266 for an on-site assessment and a straight recommendation.
