Why Mason Remodeling Is Tamalpais-Homestead Valley’s Preferred General Contractor Company

Homeowners in Tamalpais-Homestead Valley call us because we don’t start with a sales pitch. We start with a site visit, a tape measure, and a written scope. The lots up here off Panoramic Highway and along Homestead Boulevard aren’t flat suburban pads. They pitch, they drain, and they sit on geology that Marin County wants reviewed before anyone opens a wall. Our team has worked enough Tamalpais-Homestead Valley projects to know which remodels trigger geotechnical review and which ones sail through with a standard building permit. That local knowledge saves you weeks, not just dollars.
We also know what it means to let a crew into your home when you’re often home alone, or when your kids are doing homework in the next room. Every technician arrives in a clean marked uniform, shows a photo ID badge at the door, and was introduced to you by name and photo before the visit. That’s the Threshold Standard, and we don’t waive it. Isaac Pruett, who leads Mason Remodeling, built the entire operation around that standard, and it shows in how our crews treat your floors, your schedule, and your questions.
Styles & brands we work with







Hire a General Contractor in Tamalpais-Homestead Valley
Hire a General Contractor in Tamalpais-Homestead Valley when the work touches structure, plumbing, electrical, or a permit path that a handyman can’t legally and safely carry. A kitchen remodel here typically runs $14,000 to $45,000 depending on cabinet grade, countertop material, and whether you’re moving walls. A bathroom remodel lands between $9,000 and $28,000. A whole-home remodel, the kind where you’re living somewhere else for a stretch, climbs into six figures. What you’re paying for is a licensed party who pulls the right Marin County permits, coordinates the trades in the right sequence, and stands behind the work with a written guarantee.
Scoping and Written Pricing
Before we quote anything, we walk the site. Real dimensions, not napkin sketches. We confirm which walls are load-bearing, check the panel for electrical capacity, and look at how the hillside drains around your foundation. Then we deliver a written price with line items, allowances for cabinets and counters, and a draw schedule that ties payments to completed milestones. No verbal estimate that grows on the final bill. If the scope changes mid-project, you approve a change order in writing before that work starts.
Permits and Inspections in Marin County
Tamalpais-Homestead Valley is unincorporated. That means building, electrical, and plumbing permits go through Marin County, not a town hall down the street. We file the applications, schedule the inspections, and make sure the rough-in trades get signed off before drywall closes the walls. Skipping that sequence is how remodels stall for weeks and corrections get expensive.
General Contractor Services in Tamalpais-Homestead Valley
General Contractor Services in Tamalpais-Homestead Valley cover the full arc of a remodel: demolition, framing, rough-in electrical and plumbing, drywall, finishes, and final inspection sign-off. A small kitchen remodel, the kind where you keep the footprint but swap cabinets, counters, and a backsplash, runs $9,000 to $20,000 in this market. A cabinet installation alone is $4,000 to $13,000. A home addition starts around $45,000 and can reach $130,000 when you’re pushing into a hillside and adding structural steel. ADU construction, popular on larger Homestead Valley parcels, runs $90,000 to $220,000 depending on site access and foundation work.
Kitchen and Bathroom Remodels
We open kitchens up, move plumbing, and set cabinet runs that actually fit your walls. KraftMaid and Wellborn cabinetry, Cambria and Silestone counters, Kohler and Moen fixtures. You choose the finish, we write the allowance, and the price is set before the first cabinet box arrives.

Additions, ADUs, and Garage Conversions
Room additions and ADUs on Tamalpais-Homestead Valley’s slopes mean drainage plans, retaining walls, and sometimes geotechnical review. We scope that from day one so the permit path doesn’t surprise you. A garage conversion runs $30,000 to $80,000, and we’ll tell you honestly whether your existing slab and roofline can support the conversion before you spend money on drawings.

AfterCommon General Contractor Problems We See in Tamalpais-Homestead Valley Homes
- Load-bearing surprises on steep lots. Homes built into the hillside off Melrose Avenue and along Miller Avenue often have walls doing structural work that a flat-lot home doesn’t. We confirm load paths before demolition, not after the ceiling sags.
- Drainage-driven foundation movement. Water moves downhill fast in Tamalpais-Homestead Valley, and foundation cracks from poor hillside drainage are common. We scope drainage corrections into the remodel rather than ignoring the warning signs.
- Unpermitted prior work. Older homes in Homestead Valley sometimes have a bonus room or bathroom that was never permitted. Marin County sees this constantly. We bring that work up to code as part of the permit path instead of letting it poison your final inspection.
- Cabinet and countertop allowances gone wrong. A written allowance with a real dollar figure prevents the argument when you pick a quartz that costs $20 more per square foot. We line-item it. You approve it. Done.

FAQs About General Contractor in Tamalpais-Homestead Valley
Yes, in nearly every case. Tamalpais-Homestead Valley is unincorporated Marin County, so building, electrical, and plumbing permits go through county officials. Moving a sink, relocating a wall, adding circuits, or changing a gas line all trigger permits, and the county’s final inspection sign-off is what closes the job legally. We handle the full permit path from application to final sign-off. Call (803) 680-2547 and we’ll tell you exactly which permits your project needs before you spend a dollar on drawings.
Three things in Tamalpais-Homestead Valley specifically: slope and drainage, structural scope, and material grade. Steep lots often require retaining walls, drainage corrections, and sometimes geotechnical review, and that adds cost before framing begins. Written allowances for cabinets and counters keep the finish selections from becoming arguments. A kitchen remodel in this market runs $14,000 to $45,000; call (803) 680-2547 for a free estimate scoped to your actual house, not a ballpark.
A kitchen or bathroom remodel in Tamalpais-Homestead Valley generally takes 4 to 8 weeks from first demo to final inspection, assuming no structural surprises. Additions and ADUs run longer, sometimes 4 to 7 months, especially if Marin County requires geotechnical review on a steep parcel. We build a calendar into your written scope and update you at every milestone, so you’re never guessing when the crew shows up next.
You get a written change order with the exact price difference before any new work begins. No verbal side deals, no surprise invoice at the end. We write the change, you approve it, and the draw schedule adjusts accordingly. It’s how we keep projects honest from day one to punch list. Call (803) 680-2547 if you want to understand how change orders work before you sign a contract.
Yes, and Marin County’s ADU rules are more permissive than many neighboring counties, but steep lots bring real costs: foundation work, drainage, and sometimes structural reinforcement. A garage conversion in Tamalpais-Homestead Valley runs $30,000 to $80,000, and an ADU starts around $90,000 and can reach $220,000. We scope the site first, then tell you whether the numbers work before you commit to drawings. Call (803) 680-2547 and we’ll schedule a free site visit.
