Fast, Reliable General Contractor Across Monte Sereno
Finding a General Contractor who understands Monte Sereno’s specific realities matters more here than almost anywhere else in the Bay Area. This is not a tract-home town. Nearly every project we take on in Monte Sereno involves an older custom home on a hillside lot with mature trees, strict design review, and the kind of hidden conditions that turn a six-week remodel into a six-month headache if nobody planned for them. We have been working in and around Monte Sereno long enough to know what those conditions look like before we open the first wall. Call (866) 472-1908 to talk through your project with Noel Carvalho directly.
Why San Bruno Construction Is Monte Sereno’s Preferred General Contractor Company
Monte Sereno homeowners tend to ask sharper questions than most. They have seen remodel horror stories, they have talked to neighbors who went through design review, and they want someone who can speak to the actual mechanics of a project, not just smile and promise a timeline. That is exactly how Noel Carvalho runs San Bruno Construction. We walk the property, look at the slope, check the existing foundation, and talk through what the city will require before we put a number in front of you.
Our reputation in Monte Sereno has been built on doing what we say we will do. When we tell a homeowner on Daves Avenue that their addition will trigger a tree protection report, we are telling them that because we have done additions on Daves Avenue. When we quote a kitchen remodel in the hills above Highway 9, that quote includes allowances for the things we know we will find once the drywall comes down. Monte Sereno is not a place where you can wing it. The city’s design guidelines see to that.

Hire a General Contractor in Monte Sereno
Hire a General Contractor in Monte Sereno who understands what the city’s compatibility review means for your timeline and your budget. Monte Sereno’s residential design guidelines require a level of architectural scrutiny that neighboring Saratoga and Los Gatos simply do not impose to the same degree. Even a straightforward interior remodel can trigger design review, and any exterior work almost certainly will. That is not a reason to avoid the work. It is a reason to hire someone who has already navigated the process and knows what the planning department will ask for before you submit.
What does hiring us actually involve here? An inspection-first approach. We do not open a load-bearing wall in a 1970s Monte Sereno home without knowing what is behind the drywall, because we have seen what is behind the drywall in those homes. And we write allowances into every contract, so when the inevitable hidden condition appears, it is handled as a documented change order, not a vague “extra” at the end.
Inspection Before Demolition
Every Monte Sereno remodel starts with a careful look at what is actually in the walls, the crawl space, and the attic. Hillside homes built in the 1960s through 1980s often hide cloth-wrapped wiring, undersized framing, and failed waterproofing. We find it before the demolition crew does, so the pricing reflects reality.
Written Change Orders, Never Verbal Extras
If we find something the inspection could not have predicted, work stops. You get a written description of what we found, what it costs to fix, and what the options are. Nothing proceeds until you approve it. That is how we keep a Monte Sereno remodel predictable even when the house is not.
General Contractor Services in Monte Sereno
General Contractor Services in Monte Sereno mean something different than they do in a flat, tract-built neighborhood. The lots are large, the homes are custom, and the terrain is unforgiving. You need someone who can coordinate framing, electrical, plumbing, roofing, windows, siding, and hardscaping under one contract, and who knows how to sequence that work around the rainy season. Monte Sereno’s Mediterranean climate means dry summers and wet winters, so exterior work gets scheduled accordingly. Drainage and erosion control on hillside sites are not afterthoughts, they are part of the plan from day one.
Our sub-service range covers everything from a single bathroom to a full second-story addition. Here is what Monte Sereno homeowners most often hire us for:
Kitchen and Bath Remodels
A kitchen remodel in Monte Sereno typically runs $14,000 to $45,000, and a bathroom remodel $9,000 to $28,000, depending on footprint and material choices. Those figures assume you are working within an existing footprint. Moving plumbing or load-bearing walls changes the number, and on hillside homes that is common.

Additions and ADUs
A home addition in Monte Sereno runs $45,000 to $130,000, and an ADU can run anywhere from $90,000 to $220,000 depending on whether you go with a site-built structure or a prefab unit from a brand like Abodu or Plant Prefab. Hillside foundation work, pier-and-grade-beam systems, and tree protection requirements all affect the final figure, so we scope these carefully before quoting.

AfterCommon General Contractor Problems We See in Monte Sereno Homes
- Cloth-wrapped wiring behind original drywall. Homes built in the 1960s and 1970s in Monte Sereno frequently still have original branch wiring that no longer meets code. Once walls are open, the electrical upgrade is mandatory, and it is not cheap. We look for this before we quote, not after.
- Undersized framing on hillside additions. Sloped lots put lateral loads on structures that flat lots do not. Older additions often skimped on shear wall and beam sizing. A permit-triggered structural upgrade can add $5,000 to $15,000 to a project, and we make sure that number is on the table before work begins.
- Failed waterproofing on deck and balcony connections. Monte Sereno’s wet winters find every gap. We regularly see ledger boards with dry rot and missing flashing where decks meet the house. If you are doing any exterior work, we inspect these connections as part of the scope.
- Design review surprises. Homeowners sometimes assume an interior remodel skips city review. It often does not. Monte Sereno’s compatibility review can require architectural drawings and neighborhood notification, and tree removal or even root-zone encroachment can trigger an arborist report. We build that into the timeline so you are not blindsided.
Pricing for General Contractor in Monte Sereno, CA
Here are the numbers Monte Sereno homeowners ask about most often, based on the projects we have scoped in and around the 95030 zip code:
| Project Type | Monte Sereno Price Range |
|---|---|
| Kitchen Remodel | $14,000 – $45,000 |
| Bathroom Remodel | $9,000 – $28,000 |
| Home Addition | $45,000 – $130,000 |
These ranges reflect today’s Monte Sereno market, where custom homes on large lots mean bigger footprints, higher-end material selections, and more engineering than the Bay Area average. What moves the number within each range? Structural work, electrical upgrades, foundation scope, and your material picks. Cambria countertops cost more than a standard quartz, but the difference matters less than whether we find undersized framing once the wall is open. That is why we quote allowances and write change orders the way we do. Call (866) 472-1908 for a free estimate, and we will walk the property and give you a number that reflects your actual house, not a generic formula.

FAQs About General Contractor in Monte Sereno
Expect to find something the original builder left behind. Cloth-wrapped wiring, missing insulation, undersized headers, or dry rot at exterior connections are all common in 1960s and 1970s custom homes in Monte Sereno. The cost of fixing these issues is not optional once the wall is open and the inspector is involved. That is why we inspect before we quote, and we write allowances into the contract so those costs are anticipated, not shocking. Call (866) 472-1908 to schedule an inspection of your home before you commit to a remodel number.
Monte Sereno’s residential design guidelines require compatibility review that goes beyond what Saratoga or Los Gatos require. Even an interior remodel that changes the building envelope or roofline will likely need architectural drawings and city review. Exterior changes almost always do. Budget four to eight weeks for design review on top of your construction timeline, and if trees are involved, add time for an arborist report. We handle the paperwork and sequencing so the waiting does not become your second job.
Yes. Monte Sereno’s hillside lots and mature oaks and redwoods mean many projects need pier-and-grade-beam foundations to protect root zones, plus arborist reports and tree protection plans as part of the permit package. We coordinate the structural engineer, the arborist, and the city so you have one point of contact. This is not a specialty service we occasionally dabble in. It is a routine part of building in Monte Sereno.
A change order is a written document that describes a change in scope, the reason for it, and the exact cost, signed by you before any additional work begins. On a 1970s ranch in the hills above Highway 9, our crew opened a load-bearing wall for a kitchen remodel and found cloth-wrapped wiring and undersized framing that no longer met code. We stopped work, priced the electrical and structural upgrades as a written change order, and got the homeowner’s approval before proceeding. No vague extras, no end-of-project surprises. That is the standard on every San Bruno Construction job.
We pull the permits, schedule every inspection, and stay on site until the final sign-off is complete. Monte Sereno’s planning and building department is thorough, and hillside work gets scrutinized. That is fine. We would rather the inspector catch something than have you discover it five years later. Every project we run in Monte Sereno ends with a closed permit file and a final walkthrough with Noel Carvalho.
