CGI Construction in Hillsborough, CA | Seaside Contractors
We’re an independent contractor providing CGI kitchen cabinet, countertop, and walk-in shower service across Hillsborough. The one thing that makes our CGI work different here is that we understand how this town’s hillside moisture, fog-belt sun, and design-review process affect every cabinet box and countertop seam. Call (833) 589-8103 for a free estimate from a team that has worked CGI products inside Hillsborough estates for years, not as a manufacturer rep, but as the contractor who installs, repairs, and stands behind the work.
Why Hillsborough Residents Choose Us for CGI Service
Most contractors in Hillsborough know framing and finishes. Few know the specific way a CGI all-plywood cabinet behaves after three wet winters against a hillside-grade wall. We do, because we’ve seen it. Our team has installed and serviced CGI sales & service product lines inside Hillsborough homes from the flat streets near the town hall to the steep lots off Hayne Road and Ralston Avenue. We know which CGI door profiles hold up under the south-facing sun exposure that bakes the west elevations of so many Hillsborough estates, and we know which hinge and glide packages start to bind when a home sits in year-round open-window humidity from pool evaporation and fog. Glen Sorrento, our owner, grew up on the Peninsula and studied building construction technology at College of San Mateo, then spent two-plus decades working projects from waterfront decks to full kitchen remodels. Let’s figure out what the job actually needs, then we’ll talk materials. That’s how we approach every CGI service call in Hillsborough.

Common CGI Construction Problems We Solve in Hillsborough
Here’s what we see on Hillsborough jobs, and why it happens here more than in neighboring towns:
- Toe-kick and vanity back swelling from slab moisture. Hillsborough’s winter rains soak into hillside soil, and groundwater wicks up through slabs and grade-level framing. The first sign is usually a swollen CGI toe-kick or a vanity back panel that’s soft behind the cabinet, not a visible plumbing leak. We trace the moisture path, then fix the cabinet and the drainage issue together.
- Painted and thermo-foil door faces checking on south and west elevations. Hillsborough estates catch strong afternoon sun and glare, especially on the west-facing rooms that overlook the bay side of the Peninsula. CGI painted and thermo-foil doors on those exposures can develop hairline checking or peel at the edges within a few seasons. We refinish or replace doors and match the sheen to the original CGI finish.
- Quartz slab edge and sink-rim chipping from settled cabinet boxes. Sloped lots mean framing moves, even on million-dollar foundations. When a CGI cabinet box goes slightly out of level, the counter slab takes the stress, and you see chipping at the sink rim or along the front edge. We relevel the cabinet, shim the box, and re-template the stone to the settled line before reseating it.
- Hinge and drawer-glide failure from persistent humidity. Homes with pools, guest houses, and fog-belt air circulation often leave windows open much of the year. CGI soft-close hinges and ball-bearing glides that would run quietly in a sealed house can start grinding or sagging in that environment. We replace with genuine CGI hardware when available, or a quality aftermarket part when the original is discontinued.
- Shower and vanity package seams opening on hillside walls. CGI frameless glass and vanity lines are designed for plumb, square substrates. Hillsborough’s sloped framing rarely is. We see gaps opening at the top of shower glass panels and vanity backs pulling away from out-of-square walls. The fix is leveling the substrate, not forcing the panel.
CGI Service in Hillsborough: What Local Conditions Mean for Your Equipment
Hillsborough’s own design-review and hillside/grading requirements mean even a modest kitchen or bath addition can trigger architectural review plus geotechnical and drainage review before a permit issues. That local scrutiny often pushes CGI cabinet and shower scopes into engineered retaining-wall and waterproofing work that a same-size project in CGI service in San Mateo or Burlingame would never require. On a gated estate off Hayne Road, our crew opened a kitchen wall for a CGI cabinet run and found the hillside-grade slab wicking moisture into the toe-kicks and vanity backs. We stripped the swollen boxes, installed a capillary break and sealed the slab edge, then reset new CGI all-plywood cabinets on adjustable legs with sealed sink rims and templated the quartz to the settled wall line. The homeowners got a dry, level kitchen without a full tear-out, and the drainage detail passed the town’s grading review. That’s the difference between a contractor who knows CGI cabinets and one who knows Hillsborough permitting. We’re both, and we plan for the review from the first site visit.
CGI Models & Products We Service in Hillsborough
We service the full CGI product range across Hillsborough’s 94010 zip code: ready-to-assemble all-plywood kitchen cabinets, semi-custom painted and stained cabinet lines, quartz and granite countertop programs, and frameless glass shower and vanity package lines. Our parts approach is straightforward: we use genuine CGI replacement doors, drawer boxes, glides, and hinges where the cabinet box is sound, and we’ll tell you when a quality aftermarket part is the better call because a CGI part is discontinued or backordered. On Hillsborough jobs we lean toward repair and refinish when the box is plumb and dry, and recommend full replacement only when moisture or settling has compromised the substrate. We stock common CGI hinge and glide parts locally for faster turnaround, and we order doors and drawer fronts to match your existing line rather than guessing at finishes.

FAQs – CGI Construction in Hillsborough
If the remodel changes the building envelope, adds square footage, or touches exterior walls, yes, it likely triggers Hillsborough’s architectural review plus geotechnical and drainage review. Interior-only cabinet and counter replacements usually do not, unless the scope includes a new window, door, or structural change. We’ll identify which path your project takes before any permit is filed. Call (833) 589-8103 and we’ll walk the site with you.
It’s almost always slab or grade-level moisture wicking up through the foundation, not a plumbing leak. Hillsborough’s hillside lots hold water after winter rains, and that moisture moves through concrete and framing into the lowest point of your cabinet box. We solve it at the source with a capillary break and sealed slab edge, then replace the damaged CGI components. Call (833) 589-8103 for a moisture check and cabinet assessment.
Yes, and this is common in Hillsborough homes on sloped lots. We level the cabinet boxes first, shim to the settled wall line, then template the CGI quartz to the actual wall rather than an idealized square room. This prevents the edge chips and sink-rim fractures you’d get from forcing a straight slab onto a crooked wall. Ask us about this when you call (833) 589-8103.
Possibly, if the shower extends the home’s footprint or changes exterior drainage. Hillsborough’s hillside and grading rules are stricter than neighboring towns, and a shower that captures exterior wall space can fall under drainage review. We’ll tell you honestly before you spend a dime. Call (833) 589-8103 for a straight answer on your specific plan.
No. Seaside Contractors is an independent contractor. We are not authorized, sponsored, or endorsed by CGI, and we don’t pretend to be. What we are is a team that has installed and serviced CGI product lines in Hillsborough homes for years, and we stand behind the work we do. Call (833) 589-8103 and we’ll show you the difference.
