Remodeling Company in Larkspur, CA
Mason Remodeling is the remodeling company Larkspur homeowners call when they want a written price before any work starts and a crew they can identify by name and photo before the door opens. Larkspur is not a tract-home town. It’s a place of 1930s bungalows off Magnolia Avenue, 1950s ranchers climbing the hills above Sir Francis Drake Boulevard, and newer builds tucked against the redwoods near Baltimore Canyon. That mix means every project here starts with questions other cities never ask: how the foundation sits on the slope, what the original framing can carry, and whether the city will want drawings before a single wall moves. Call (803) 680-2547 and we’ll tell you what’s possible, what it costs, and what we’ll put in writing.
Why Larkspur Homes Are Different
Larkspur sits in a narrow valley between Corte Madera Creek and the ridge that separates it from Kentfield, and that geography shows up in the housing stock. Older homes in the flats, particularly the streets off Magnolia Avenue near the historic downtown, frequently sit on post-and-pier foundations that have settled unevenly over 80 or 90 years of wet winters. Walk the floors in some of those houses and you’ll feel the slope before you see it. That’s not a defect; it’s the natural history of building on bay-margin soil. But it changes the remodel math. A bathroom gut in a 1938 bungalow often means sistering floor joists and re-leveling a section of subfloor before tile goes down, and that cost belongs in the written estimate, not discovered as a surprise change order.
Homes in the hills above Madrone Canyon and up toward the King Mountain Open Space face a different set of conditions: steep driveways that complicate material staging, retaining walls that must be respected during excavation, and decks that were built under older code and need structural review before any addition ties into them. Wildfire-adjacent zones in the upper reaches of Larkspur also bring upgraded siding and ventilation requirements under current California building code. Add in a planning department that reviews carefully and an active HOA presence in several of the newer subdivisions, and you have remodel projects that reward whoever did the homework before demolition day. That’s the work we do.
Styles & brands we work with
Our Main Larkspur Services
Larkspur homeowners tend to reach out for two kinds of work: whole-project leadership through a complicated remodel, and bathroom overhauls in homes where the existing layout fights the plumbing. Each service has its own Larkspur page with local pricing and scope details.
General Contractor in Larkspur
Acting as General Contractor in Larkspur means running the permits, the subs, the inspections, and the schedule on jobs where the homeowner should not be the one coordinating electricians and structural engineers. In Larkspur, that coordination often includes older-home structural surprises and hillside access planning. We deliver a written price with scope defined before demolition starts, and the 365-Day Done Right Promise applies to every general contracting project we complete.
Bathroom Remodeling in Larkspur
Bathroom Remodeling in Larkspur usually starts with the question of whether the footprint can stay put or must move to make the room usable. In 1940s and 1950s homes, the original bathrooms are often small, with cast-iron drain stacks in stubborn locations. We handle the plumbing reality of those older builds, then bring the finishes up to what Larkspur buyers and owners expect. Larkspur bathroom remodels typically run $9,000 to $28,000 depending on whether walls move and what’s hiding behind them.
Home Remodeling in Larkspur
Larger Home Remodeling in Larkspur projects, the kitchen-and-family-room reconfigurations and whole-home updates, put the most pressure on the old framing and the hillside foundation. We sequence that work so the house remains livable as long as practical, and we keep the paperwork straight with the city so inspections don’t stall the schedule. Every home remodel in Larkspur gets a written guarantee stating coverage terms, exclusions, and duration: 365 days from the completion date.

What pushes a Larkspur project toward the top of a range is almost always the structure hiding behind the drywall: settled foundations in the flats, shear-wall upgrades on the hillsides, or old plumbing that no longer meets Marin County code. We write every price before we open a wall, and we don’t come back later with a bigger number unless the scope actually changes and you approve it in writing first.
