Fast, Reliable General Contractor Across Los Gatos
Hiring a General Contractor in Los Gatos means navigating a town with two very different sets of rules. The flatlands around downtown follow one playbook. The hillside parcels in ZIP 95033 follow another. We manage both under one contract, so you’re not coordinating architects, the Heritage Preservation Committee, and Santa Clara County fire inspectors on your own. If you’re planning a remodel or addition anywhere in Los Gatos, call us at (855) 901-7266 for a free, honest scope review.
Our team has worked on Craftsman bungalows in the Almond Grove neighborhood, mid-century ranches near Blossom Hill Road, and engineered hillside builds off Bear Creek Road. Each comes with its own permit sequence and material requirements. The point of hiring one contractor is that we already know which track your project falls into before the first permit is filed.
Why San Mateo Construction Is Los Gatos’s Preferred General Contractor Company
Los Gatos homeowners tend to ask sharper questions than most. They want to know whether the window package meets the Historic Preservation Committee’s standard or whether the roofing assembly carries a Class A fire rating for WUI compliance. Those are the right questions, and we answer them with product-level detail, not vague assurances.
We carry relationships with more than 50 brand-name suppliers, which matters in Los Gatos because different neighborhoods demand different material tiers. A downtown Victorian needs custom wooden windows that match the original profiles. A hillside addition needs PGT impact-rated glazing and fire-resistant siding. We help you choose from vetted brands like Boral and CGI rather than whatever a subcontractor happens to have in stock. Noel Carrington, our owner, personally reviews every Los Gatos estimate before it leaves our office, because the dual permitting environment here leaves no room for sloppy scoping.

General Contractor Services in Los Gatos
General Contractor Services in Los Gatos cover full-scope remodeling, additions, and new structures, managed under one contract from roofline to foundation. Homeowners call us when a project touches multiple trades and multiple permit tracks. A kitchen remodel here typically runs $14,000 – $45,000 depending on the neighborhood and the age of the house. A bathroom remodel runs $9,000 – $28,000. Those ranges assume code-compliant work, which is the only kind worth doing in this town.
Remodeling and Renovation
We handle kitchen and bath remodels, whole-home renovations, and structural upgrades. In Los Gatos, a 100-year-old Craftsman needs seismic retrofits and material matching before you even get to the finishes. We sequence that work so the structural inspection happens before the cabinets go in.

Additions and ADUs
Room additions and ADU construction in Los Gatos run $45,000 – $130,000 and $90,000 – $220,000 respectively. Hillside parcels usually need engineered foundations and retaining walls, which we quote as line items upfront. We also build through prefab partners like Abodu and Dvele when the site conditions support it.

Construction Company in Los Gatos
A Construction Company working in Los Gatos has to understand what the town actually enforces. We recently completed a hillside addition in the Santa Cruz Mountains portion of ZIP 95033, where steep slopes required an engineered foundation and retaining wall. Our crew used fire-rated roofing and siding to meet the county’s WUI standards, and we documented every inspection sign-off to ensure the homeowner could qualify for insurance discounts. The project passed final inspection without a single change order, thanks to a detailed scope of work and draw schedule agreed upfront.
Exterior Systems
Roof replacement in Los Gatos ranges from $8,000 – $20,000. On hillside parcels, we specify GAF, CertainTeed, or Owens Corning Class A assemblies that satisfy the county’s fire-safe standards. Impact window installation runs $8,000 – $25,000, and we stock PGT and CGI lines for both WUI and non-WUI zones.
Permit and Inspection Management
We pull permits and manage inspections for every project. In Los Gatos that can mean a Heritage Preservation Committee review for a downtown window swap and a county fire inspection for a hillside siding replacement, sometimes on the same job. One contractor, one accountable point of contact.
Trusted Brands We Service in Los Gatos
We maintain curated access to brand-name products across every system in your home. On the exterior side, that includes Boral siding, PGT and CGI windows and doors, and Tamko roofing products alongside GAF and CertainTeed. We stock common local replacement parts for Los Gatos jobs and can source specialty lines fast. When a downtown project calls for period-appropriate custom windows and a hillside project calls for impact-rated glazing, you don’t want to be limited by a contractor with three supplier relationships. You want options, and we help you choose between them honestly.

AfterCommon General Contractor Problems We See in Los Gatos Homes
- WUI zone misclassification. A homeowner starts a hillside remodel assuming standard materials are fine, then fails a county fire inspection because the roofing or siding isn’t fire-rated. We verify the property’s WUI status before quoting, so the first quote is the right quote.
- Skipped Heritage Preservation Committee review. Downtown remodels in Old Town can trigger a design review that requires period-appropriate materials. Skipping it means a stop-work order and a redesign. We check the address against the town’s historic inventory early.
- Vague allowances for fire-resistant materials. A cheap quote might include a line item for “roofing” without specifying the assembly. When the compliant product costs 30% more, the budget blows up. We write exact product names and ratings into every Los Gatos estimate.
- Foundation surprises on hillside parcels. Slopes in the Santa Cruz Mountains portion of Los Gatos frequently require engineered caissons or retaining walls. We include a geotechnical review in our scope for any addition or ADU on a slope over 15%, so the foundation number is real.

FAQs About General Contractor in Los Gatos
Hillside homes in Los Gatos within the Wildland-Urban Interface zone must use Class A fire-rated roofing assemblies, which typically means GAF, CertainTeed, or Owens Corning products installed with fire-resistant underlayment. Call (855) 901-7266 and give us your address; we’ll verify your WUI status and quote the exact assembly required.
No, only properties within the town’s designated historic district or on the historic inventory require Heritage Preservation Committee review. We check your address against the town’s records before quoting, so you don’t get surprised by a design review after the fact. Call us for a free scope check if you’re unsure.
Documented compliance with WUI fire-safe building codes can qualify Los Gatos homeowners for insurance discounts and, in some cases, continued coverage on hillside parcels. Insurers increasingly ask for proof of Class A roofing and fire-resistant siding before renewing policies in the 95033 ZIP. We provide an inspection and compliance package at project closeout.
A cheap quote usually contains vague allowances, skips WUI verification, and doesn’t account for Heritage Preservation Committee review or engineered foundations. A compliant quote names exact products, includes permit and inspection fees, and sequences the dual permitting tracks. Call (855) 901-7266 for a free, line-item estimate that won’t change once work starts.
We file on both tracks in parallel and sequence the work so no inspection blocks another. That means submitting Heritage Preservation Committee documentation for downtown components while the county reviews the fire-safe assemblies for the hillside portion, so the project moves without stop-work delays. It’s the main reason Los Gatos homeowners hire one contractor instead of three.
If you’re planning a remodel, addition, or ADU anywhere in Los Gatos, call (855) 901-7266 for a free estimate. We’ll tell you which permit track you’re on, what it means for your materials, and what the work will actually cost.
