Remodeling Company in Hillsborough, CA
Home remodeling in Hillsborough runs from $9,000 for a small bathroom refresh to $130,000 for a major whole-home renovation, with most kitchen and bath projects landing between $14,000 and $45,000. We’re Elmstead Remodeling, a Cedarwell company, and we handle gut renovations of 1920s Spanish Colonial estates, seismic retrofits for hillside homes, and modern whole-house updates that must clear the city’s Architectural Review Board. Our crews work with the clay-heavy soils, mature coast live oak root zones, and unreinforced masonry chimneys that surface in nearly every older Hillsborough project. Call (949) 850-9896 to schedule your free estimate.
Why Hillsborough Homes Are Different
Hillsborough is California’s wealthiest entirely-residential municipality, with zero commercial zoning and no apartments, which means every construction project faces scrutiny from the Architectural Review Board and a building department known for exacting standards. The housing stock is almost exclusively large single-family estates on minimum half-acre lots, with a significant core of 1920s – 1950s formal-style homes featuring original unreinforced masonry chimneys, galvanized or early copper plumbing, and knob-and-tube wiring that surfaces in nearly every gut renovation.
The western neighborhoods rise sharply into the Santa Cruz Mountains foothills, and the wet-season saturation of clay-heavy hillside soils creates recurring slope instability, retaining-wall failures, and drainage-system overload on upper-elevation estates. The San Andreas Fault corridor runs roughly 2 – 3 miles west through Crystal Springs Reservoir, making seismic retrofitting of older unreinforced foundations and cripple-wall systems a standard line item across the city. Hillsborough’s tree-protection ordinance shields mature coast live oaks that sprawl across nearly every estate lot; any construction within the drip line requires a certified arborist’s sign-off and root-zone protection plan before permits issue, adding weeks and specialized costs that neighboring Burlingame or San Mateo projects rarely incur.
Styles & brands we work with
Our Main Hillsborough Services
Most Hillsborough homeowners who call us start with one of these three projects, each shaped by the city’s unique building requirements and estate-scale homes.
General Contractor in Hillsborough
We coordinate multi-trade estate projects that must satisfy the Architectural Review Board while integrating seismic retrofits, drainage corrections for hillside lots, and period-accurate restoration of original clay roof tile or heritage lime plaster. Every project gets a written price before work starts, background-checked uniformed technicians, and our 365-Day Done Right Promise. General Contractor in Hillsborough covers our full build-management approach for these complex, board-reviewed jobs.
Bathroom Remodeling in Hillsborough
Estate bathrooms in Hillsborough often require gut-level work: replacing galvanized supply lines, updating electrical for heated floors and modern fixtures, and selecting materials that satisfy both the homeowner and the Architectural Review Board’s material standards. We use Kohler, Moen, and Grohe fixtures with manufacturer warranties you can verify, and we protect original hallway millwork and period tile with drop cloths and careful demolition sequencing. Bathroom Remodeling in Hillsborough details our process for these precision jobs.
Kitchen Remodeling in Hillsborough
Hillsborough kitchens typically involve opening walls between formal dining and cooking spaces while preserving or matching original crown molding, coffered ceilings, or heritage plaster. We source cabinets from KraftMaid and Wellborn, countertops from Cambria and Silestone, and manage the electrical upgrades that knob-and-tube removal demands. Our crew uses quiet tools during family rest hours where possible and asks before moving any furniture or artwork. Kitchen Remodeling in Hillsborough explains how we handle these sensitive renovations.

Home Remodeling in Hillsborough
Home remodeling in Hillsborough means reconciling period estate architecture with modern seismic, electrical, and plumbing codes in a city where every project passes the Architectural Review Board. We regularly open walls in 1930s Mediterranean Revival homes to find knob-and-tube wiring and galvanized pipes, then design systems that meet current code without destroying original plaster crown or custom millwork. Our Home Remodeling hub explains our full-service approach; here’s how we handle the most common Hillsborough project types.
Whole House Remodel
Signs you need it
Your 1920s – 1950s estate still has original knob-and-tube wiring, galvanized plumbing, unreinforced masonry chimneys, and a floor plan that doesn’t match how your family lives now.
What it costs in Hillsborough
A whole house remodel in Hillsborough typically runs $45,000 – $130,000, with most estate-scale projects landing in the upper half of that range once seismic retrofitting, arborist consultations for coast live oak protection, and Architectural Review Board compliance are factored in.
How we do it
We sequence the work by floor to keep your family in residence where possible, protect original features with custom-built dust containment, coordinate the certified arborist and geotechnical reports the city requires, and deliver a written price before any demolition begins.
Luxury Home Remodeling
Signs you need it
You’re updating a formal estate with original architectural details you want preserved and enhanced, not stripped out for a generic modern look.
What it costs in Hillsborough
Luxury home remodeling in Hillsborough starts around $45,000 for focused high-end renovations and extends well above $130,000 for whole-estate work involving custom millwork replication, imported materials, and extended Architectural Review Board design review.
How we do it
We photograph and catalog every original molding profile, plaster finish, and hardware specimen before touching anything, replicate missing elements with local specialty millwork shops, and install KraftMaid or Wellborn cabinetry with Cambria or Silestone surfaces that meet the board’s material-quality expectations.
