Fast, Reliable General Contractor Across Foster City
Most Foster City homeowners call us when a builder-grade kitchen or bathroom has reached the end of its life, or when a growing family needs more square footage than a 1970s lagoon-front home was ever designed to offer. We know this city’s housing stock, its HOA rulebooks, and the bay mud underneath every street. Ken Stafford leads Milpitas Construction, and we’ve managed remodels, additions, and ADU projects throughout the 94404 zip code. Call (877) 752-4194 to schedule a free estimate, and we’ll walk your property before we talk numbers.
Why Milpitas Construction Is Foster City’s Preferred General Contractor Company
Foster City homeowners tend to be methodical. They read their HOA covenants, they ask about warranty implications, and they want a contractor who can explain why a specific foundation detail matters on engineered fill. That’s the conversation we’re built for. We’ve worked in the Islands, the Whaler Isle loop, and the Marlins Point development off Foster City Boulevard, so we arrive already familiar with the slab-on-grade construction, the original aluminum wiring, and the sewer laterals buried under 40-year-old landscaping.
Our local reputation comes from the way we handle the unglamorous parts of a project: pulling the original soils report before we move a wall, submitting architectural review packages that pass the first time, and scheduling dewatering before excavation. Homeowners in Foster City tell us that’s the difference between a contractor who quotes fast and one who actually finishes. We carry full general liability and workers’ compensation coverage, and every project gets a written line-item scope before we start.
You’ll work directly with Ken Stafford from first walkthrough to final punch list. No rotating project managers, no subcontractor roulette. The team that specs your KraftMaid cabinets is the same team accountable for the Cambria countertop install and the permit sign-off.
Styles & brands we work with
Hire a General Contractor in Foster City
Hire a General Contractor when your Foster City project touches structure, waterproofing, load paths, or anything regulated by the city’s building department and your HOA’s architectural committee. A kitchen remodel in a 1970s Foster City home runs $14,000 – $45,000, while a full bathroom remodel lands between $9,000 and $28,000. Home additions are a bigger conversation, typically $45,000 – $130,000 depending on square footage, foundation work, and whether you’re building on grade or over a crawlspace that’s actually a shallow slab over bay mud.
Warranty-Safe Interior Upgrades
The first thing we check is whether your home still carries builder warranty coverage. Pulling a load-bearing wall or rerouting rough-in plumbing without documentation can void it. We check the original plans, confirm what’s structural, and design the scope so your warranty stays intact.
Exterior Work That Clears HOA Review
Window replacements, paver driveways, fencing, and any visible exterior change in Foster City’s master-planned communities usually needs architectural approval first. We prepare the submittal package with material specs, color samples, and site drawings, then manage the approval timeline so construction isn’t waiting on committee meetings.
General Contractor Services in Foster City
General Contractor Services in Foster City means handling the whole project under one contract: demolition, rough-in, finishes, inspections, and the paperwork between. Cabinet installation runs $4,000 – $13,000, countertop installation $2,000 – $6,500, and a full kitchen remodel with structural changes starts around $14,000. Our crews handle the sequencing so you’re not coordinating an electrician, a plumber, and a cabinet installer on three different schedules.
Kitchen and Bath Remodels
Most Foster City kitchens we see are original builder packages: oak frames, laminate tops, fluorescent soffits. We replace them with KraftMaid or Wellborn cabinetry, Cambria or Caesarstone counters, and Kohler or Grohe fixtures, all spec’d by name so you know exactly what’s going in.
Additions and ADUs
Adding square footage in Foster City means dealing with the water table. We bring in a geotechnical engineer early, determine whether dewatering is required, and build on a foundation system matched to the bay mud. We also handle prefab ADU construction through manufacturers including Abodu, Dvele, and Mighty Buildings, which can shorten the on-site build time substantially.

Trusted Brands We Service in Foster City

For Foster City fencing, we install Jerith aluminum, Bufftech vinyl, and ActiveYards systems that hold up to the marine air better than untreated wood. For hardscaping, we use Belgard pavers on patios and driveways where HOA rules allow paver surfaces. Because we stock or have direct access to local inventory, Foster City projects don’t stall waiting on a distributor across the Bay. Fast turnaround, no mystery materials, and a warranty that covers both product and installation.

AfterCommon General Contractor Problems We See in Foster City Homes
- Excavation hitting groundwater at 18 inches. Foster City’s high water table means even a shallow dig for a new island footing can flood. We plan dewatering before we open the ground, not after the hole fills up.
- Original aluminum wiring and aging sewer laterals. Most 1960s – 1980s homes in the 94404 zip code still have aluminum branch circuits and clay or cast iron laterals under mature landscaping. Remodels that open walls or extend plumbing should address these while the walls are already open.
- HOA architectural review rejections. We see paver driveways and window replacements get flagged because the submittal lacked material specs or color samples. We handle the paperwork so the committee approves it the first time.
- Builder warranty voided by undocumented structural changes. Homeowners remove a wall or move a drain line, then discover the builder won’t cover a future foundation issue. We verify against the original soils report and structural drawings before any modification happens.

FAQs About General Contractor in Foster City
Yes, if the work is documented against the original structural plans and doesn’t modify load-bearing walls or rough-in plumbing without proper engineering review. We pull the original soils report and structural drawings before touching any wall, confirm what’s bearing and what’s not, and build your scope around those constraints. Call (877) 752-4194 and ask Ken to review your warranty language before you sign anything.
Interior bathroom remodels usually don’t require HOA approval unless you’re moving plumbing that affects shared walls, changing exterior vent locations, or modifying the unit’s footprint. Exterior changes like new windows, exhaust fans, or altered rooflines do require architectural review. We handle the submittal, and if your HOA has a specific form, we’ll fill it out with the right material specs and drawings.
Every addition in Foster City sits on engineered fill over bay mud, so we bring in a geotechnical engineer to check the original soils report and determine whether your design needs pier-and-grade-beam support or additional compaction testing. Excavation often hits groundwater within a couple of feet, which means a dewatering plan goes into the scope before we ever open the ground. Skipping that step is how foundations crack and basements flood.
A straight cabinet swap with no structural, plumbing, or electrical changes typically doesn’t require a building permit in Foster City. But once you move a sink, add an island with power, or remove any wall, permits are required and the city will want to see engineering on anything structural. We pull permits ourselves and stand behind the work through final inspection. Call (877) 752-4194 if you’re unsure whether your scope needs one.
We start with a soils report and property survey, then design the addition around the bay mud conditions and your HOA’s setback rules. After architectural review and city permits, we handle dewatering, foundation work, framing, rough-in, finishes, and final inspection. Most Foster City additions take four to seven months from permit approval to move-in, depending on square footage and weather. Ken Stafford manages the schedule personally, so you always know what’s happening this week and next.
