  • 365-Day Done Right Promise: if the work isn’t right within a year of completion, we make it right at no cost.
  • Tamalpais-Homestead Valley permits go through Marin County, not a town building department, and we handle that path from first filing to final inspection.

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

A garage converted into a guest room and home office

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.

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.

Trusted Brands We Service in Tamalpais-Homestead Valley

We install and service specification-grade materials from brands that hold up in Marin County’s fog, dry summers, and wet winters. For cabinetry, we work with KraftMaid and Wellborn. For surfaces, Cambria, Silestone, and Caesarstone. Fixtures come from Kohler, Moen, Toto, and Grohe. We also keep relationships with local suppliers so Tamalpais-Homestead Valley customers aren’t waiting on a cabinet door shipped from across the country when a hinge fails. If you have existing materials from a prior remodel or a brand preference, we’ll write the allowance and price it accordingly, and we’ll tell you if a particular brand’s lead time will push your calendar.

Common 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.
