Remodeling Company in Berkeley, CA
Mason Remodeling is a remodeling company in Berkeley, CA that works on the city’s older hillside homes, flatland bungalows, and everything in between. Berkeley construction is shaped by three things nobody tells you until you open a wall: redwood framing from the 1920s that’s harder than modern lumber, clay soil that moves with every rainy season, and permit requirements tied to the Berkeley hills’ fire zone. If you’re planning a kitchen, bath, or whole-home remodel, call (803) 680-2547 for a free written estimate before you touch anything.
Why Berkeley Homes Are Different
Berkeley’s housing stock runs older than almost anywhere else in the East Bay. A drive through the Elmwood or Northbrae neighborhoods shows you Craftsman bungalows and 1920s Mediterranean Revival homes with plaster walls, knob-and-tube remnants, and foundations poured before seismic codes existed. When we open a Berkeley wall, we expect to find things a newer Hayward or Fremont tract home never has: diagonal shiplap sheathing, fir studs that dull saw blades fast, and old cast-iron drain lines that snap rather than bend. The hills add another layer. Homes in the Berkeley hills sit on slopes where water runoff, retaining walls, and soil creep all influence how a remodel gets engineered. The flatlands have their own issue: expansive clay soil that swells in winter and contracts in summer, which causes the hairline cracks Berkeley homeowners know so well. Permits matter here too. The city reviews structural changes carefully, and any project in the hills triggers fire-safety and hillside-ordinance reviews. We plan for that review window from day one so it doesn’t stall your timeline.
Styles & brands we work with
Our Main Berkeley Services
Berkeley homeowners call Mason Remodeling for three jobs more than any others: full general contracting where one point of contact runs the whole project, bathroom remodels where waterproofing and venting matter in older homes, and whole-home remodels that bring century-old houses into this decade. Each has its own Berkeley page with full pricing and details.
General Contractor in Berkeley
When a Berkeley remodel spans framing, plumbing, electrical, and finishes, a General Contractor in Berkeley is the person who keeps every trade on schedule and every permit moving. In Berkeley’s older homes, that often means coordinating structural fixes alongside the cosmetic work: leveling floors, sistering old joists, replacing cast-iron waste lines. Mason Remodeling runs this as one written contract with one point of contact. You get the name and photo of your project lead before they arrive, and a written price before the first tool leaves the truck.
Bathroom Remodeling in Berkeley
Berkeley bathrooms hide problems behind the tile that newer homes never see: failed shower pans, galvanized supply lines, and floor framing softened by decades of slow leaks. Bathroom Remodeling in Berkeley starts with what’s behind the wall, not what’s in front of it. We demo to the studs when needed, fix the framing and rough plumbing, rebuild the waterproofing to current code, then finish with the tile, vanity, and fixtures you picked. Written pricing covers the whole job, including the repairs found during demo.
Home Remodeling in Berkeley
Whole-home work in Berkeley often means opening several rooms at once while the family still lives there, and that changes how the project is staged. Home Remodeling in Berkeley covers multi-room reconfigurations, kitchen-plus-bath packages, and updates that bring a 1920s house up to current electrical and plumbing standards. We sequence the work so you can still cook, sleep, and function, and the 365-Day Done Right Promise means if anything isn’t right within a year of completion, we return and fix it at no cost.

Two things push Berkeley prices higher than the surrounding East Bay. First, hillside work often adds engineering and access costs: if a concrete truck can’t reach the site, pumped concrete costs more. Second, older homes regularly need structural or utility upgrades once walls are open, and those get priced into the written estimate before we start, not added as a surprise change order after demo. We deliver a written price on every Berkeley project before any work begins, and the number on that page is the number you pay.
