Remodeling Company in Hillsborough, CA
Mason Remodeling handles general contracting, bathroom remodeling, and whole-home remodeling across Hillsborough, California. Most of the homes here sit on large lots with mature landscaping, narrow winding roads, and strict architectural oversight, which means every project needs more planning than a typical Peninsula job. If you’re weighing a remodel in Hillsborough, call (803) 680-2547 for a written price before any work begins.
Why Hillsborough Homes Are Different

Hillsborough is not a standard suburban grid. The town’s minimum lot size rules have kept density low, and many properties date from the 1920s through the 1960s, with a fair number of estates built even earlier. That changes how we work. Clay soils expand and contract through wet winters and dry summers, and we see the result in foundation movement, cracked driveways, and doors that bind seasonally. Many older Hillsborough homes have redwood framing, plaster walls, and roofs built before modern seismic codes, so a simple bathroom remodel can uncover structural work that a newer tract home would never require.
The town’s hillside terrain matters too. Some streets climb steeply, lots slope in two directions, and drainage is a real design question on nearly every addition or ADU. We plan for retaining walls, proper grading, and setback rules that are tighter than in neighboring cities. Permits move at their own pace here, and the planning department asks for architectural detail that most homeowners don’t expect. That’s the reality of building in Hillsborough, and it’s why upfront planning and written pricing matter more than a verbal estimate.
Styles & brands we work with







Our Main Hillsborough Services
Most Hillsborough homeowners call us about one of three things: a full-scale remodel, a bathroom that needs reworking, or a general contractor to manage a larger project. Each service has its own dedicated page below.
General Contractor in Hillsborough
General contracting in Hillsborough usually means running a project that touches framing, electrical, plumbing, and finishes at the same time. The homes here are older, and that’s the single biggest variable. A kitchen remodel often starts with opening a wall and finding wiring that predates modern code or framing that needs reinforcement. Isaac Pruett and the crew coordinate each trade in sequence so the job doesn’t stall between phases. You’ll know who is on site by name and photo before they arrive, and every crew member carries a photo ID badge. See General Contractor in Hillsborough for the full scope.

Bathroom Remodeling in Hillsborough
Bathroom remodels in Hillsborough frequently involve working around original cast iron plumbing, water-damaged subfloors, and layouts that were designed for a different era. That’s why our written pricing comes after we look at what’s behind the walls, not before. Schluter strips, waterproofing, and proper ventilation are standard, because the Peninsula’s damp winters will find any shortcut. We stock specification-grade fixtures from Kohler, Moen, and Toto, and every job ends with a written guarantee covering 365 days from completion. Read more on our Bathroom Remodeling in Hillsborough page.

Home Remodeling in Hillsborough
A whole-home remodel here is a different animal than a cosmetic refresh. We’re often working around a family that’s still living in the house, staging work in phases, and coordinating with the town’s design review process. Hillsborough lots are large, but the homes themselves can have awkward additions from multiple decades, so the real work is making the old and new flow together. The 365-Day Done Right Promise applies to every whole-home project: if something isn’t right within a year of completion, we make it right at no cost. Details are on our Home Remodeling in Hillsborough page.

FAQs About Remodeling Company in Hillsborough

That depends on the permit. Simple remodels that don’t require design review can often start within a few weeks. Anything that needs Hillsborough’s architectural review process takes longer, sometimes several months. Call (803) 680-2547 and we’ll give you a realistic timeline for your specific project.
Some Hillsborough properties fall under homeowners association rules, and those approvals run alongside town permits. We handle both tracks, which saves you from juggling two approval processes. The written estimate includes the scope of any HOA-required documentation.
No. You approve a written price before we begin, and that’s the price. If we uncover something unexpected, we stop and discuss it with you before doing work that wasn’t in the original scope. No surprise invoices, no verbal estimates that grow on the final bill. Call (803) 680-2547 for a free estimate.
