CGI Construction in Hillsborough, CA | Toolbox Contractors
We provide independent Hillsborough General Contractor service across the area, working on the cabinetry, countertops, and exterior building products installed in some of the Peninsula’s most expensive hillside estates. The thing that makes our CGI work here different is that Hillsborough isn’t just another stop on a route – it’s a town where every project has to survive design review on a sloped, often wooded lot, and the same kitchen job can need drainage work at the floor line on one street and fire-hardened vent detailing on the next. We’re not manufacturer-affiliated, so we specify and install what actually fits the house. If you have CGI cabinets or countertops that need attention in Hillsborough, call (855) 382-3257 for a free estimate.
Why Hillsborough Residents Choose Us for CGI Service
Most crews that touch CGI products know the boxes and the slabs. What they don’t always know is what happens to those products when they’re installed in a mid-century Hillsborough estate that’s been settling on a graded lot for fifty years. We do. Norm Castellano grew up in the Muscoy area northwest of San Bernardino, learned fundamentals through San Bernardino Valley College’s construction technology program, and spent the better part of two decades untangling jobs other contractors left behind. When CGI cabinetry racks out of square because a hillside slab moved, or finish edge banding lifts from Peninsula afternoon sun, that’s work we’ve seen and corrected before. As independent contractors, we’re not beholden to any manufacturer’s spec sheet we disagree with – we use what holds up in Hillsborough’s climate and passes the town’s design review. “Tell me what you’ve got and I’ll tell you what it actually needs.” That’s how Norm runs every job.

Common CGI Construction Problems We Solve in Hillsborough
- Racked and out-of-square cabinet boxes. CGI Ready-to-Assemble and semi-custom boxes arrive flat and get assembled on site. If the room floor isn’t leveled first – and plenty of Hillsborough slabs and subfloors have settled on graded lots – the boxes go together crooked and never sit right. We pull, re-square, shim, and anchor them properly.
- Sun-faded or lifting cabinet finishes. West-facing kitchen walls on Hillsborough estates take direct Peninsula sun through oversized windows. Edge banding peels, finishes fade unevenly. We repair or reface where the box is sound, and replace only when the damage has gone structural.
- Countertop seam movement. Older mid-century homes remodeled on their original footprint often have framing that was never designed for today’s stone loads. CGI quartz or granite tops telegraph that movement as visible seams or cracks. We address the framing or leveling issue before resetting the slab.
- Exterior vent and eave detailing that fails WUI review. CGI roofing and cladding accessories installed without fire-hardening awareness at fascia, vents, and eaves get flagged during Hillsborough’s wildfire-interface plan review. We correct the detailing so the project doesn’t stall.
- Moisture damage at the floor line on lower-lot homes. Hillsborough’s flats near the town center can hold drainage water. CGI cabinet bases sitting against that moisture wick it up and break down. We recommend replacement with properly detailed base protection rather than patching.
CGI Service in Hillsborough: What Local Conditions Mean for Your Equipment
Here’s the thing about Hillsborough that changes how we scope every CGI job. The town sits in one ZIP code, 94010, but the lower flats near the town center and the upper wooded hillside are completely different build environments. A CGI kitchen on a lower-lot street may need drainage-driven moisture control at the floor line – weep details, base protection, cabinet materials that don’t wick – because winter rains pool against foundations down there. Drive one street up into the hillside, and the same kitchen job needs fire-hardened exterior detailing at every vent, eave, and fascia penetration to clear the town’s WUI plan review. One street faces water, the next faces fire. No two blocks in Hillsborough get the same scope from us, because we set the work yard by yard, not town-wide. On a wooded upper-lot estate off the hillside streets above the flats, our crew tore out a mid-century kitchen where the CGI semi-custom boxes had racked after years of floor movement. We replaced them with new CGI cabinetry shimmed and anchored to level, rebuilt the counter run with a CGI quartz top, resealed the assembly hardware with quality aftermarket slides, and detailed the exterior vent penetration to the town’s fire-hardening expectations so the rebuild passed plan review without a re-submittal.
CGI Models & Products We Service in Hillsborough
We work on the full CGI lineup that shows up in Hillsborough homes: Ready-to-Assemble kitchen and vanity cabinetry, semi-custom all-plywood box lines, the quartz and granite countertop programs, and exterior building products like roofing and cladding accessories. Where CGI OEM hinges, slides, and assembly hardware exist and match the line, we use them. When OEM availability is slow – which happens more than the brochure suggests – we move to quality aftermarket brands and tell you exactly which is which before we install. We keep common hardware and matching finish materials stocked for fast turnaround on the Peninsula, so a CGI in Burlingame or Hillsborough repair doesn’t wait on a freight shipment from a distribution warehouse.

FAQs – CGI Construction in Hillsborough
Does Hillsborough’s design review affect a CGI kitchen cabinet install? It can. Hillsborough’s architectural review process applies to discretionary remodels, and if the work touches exterior venting or envelope detailing – which kitchen work often does on hillside homes – the review can add time and requirements. We’ve worked inside that process enough to submit what passes the first time.
My CGI cabinets are out of square after the floors settled – reface or replace? If the boxes are structurally sound but cosmetically tired, we lean reface. If they’ve racked badly from slab movement, patching just moves the failure. We’ll tell you which path makes sense after we check the leveling, and a quote for either route is free.
Can you match new CGI countertops to an existing estate kitchen? Yes. We match slab material and edge profile against the existing run, and we’ll flag any seam movement risk from the framing before we set stone. Call (855) 382-3257 for an exact quote – estimates are free.
How does the hillside location change a CGI remodel scope? On lower-lot Hillsborough streets we often add drainage-driven moisture control at the floor line. On upper hillside lots, we add fire-hardening detailing at vents and eaves to clear WUI plan review. Same ZIP, different scope — and we bring the same approach to CGI repair in Highlands-Baywood Park.
Are you authorized by CGI? No. We’re an independent construction and remodeling company. We work on CGI products regularly and use OEM parts where they exist, but no brand badge is behind our recommendations – the house is.
