Fast, Reliable General Contractor Across Kentfield
Most Kentfield remodels start with a simple question: what will this actually cost, and who exactly is walking through my door? We answer both before any work begins. Mason Remodeling has served Kentfield homeowners since 2004 as part of the Threshold Group family of home-service companies, and every project starts with a written price, a named crew, and a clear scope of work. Call (803) 680-2547 and you’ll reach a live person who can talk through your project the same day.
Kentfield sits in unincorporated Marin County, which means your building permits come from Marin County Community Development rather than a city hall. That single fact shapes how we approach every job here: county plan review on hillside lots off Sir Francis Drake Blvd often flags drainage, retaining, and geotech details before a remodel or addition permit gets issued. We plan for that reality from day one, so your calendar doesn’t quietly slip while paperwork sits in review.
Why Mason Remodeling Is Kentfield’s Preferred General Contractor Company

Kentfield homeowners tend to ask sharper questions than most. They want to know who’s on the crew, what’s in the written scope, and what happens if the subfloor reveals dry rot. That’s exactly how we like to work.
Our reputation in Kentfield is built on the boring stuff done right: permits pulled before demo starts, allowances set in writing, and change orders confirmed on paper before a single board moves. Isaac Pruett, our owner, holds every Kentfield project to the Threshold Standard, which means every technician is background-checked, identity-verified, and introduced to you by name and photo before arrival. When the crew shows up, they’re in clean marked uniforms with photo ID at the door.
We serve the neighborhoods around College of Marin, Kent Woodlands, and the streets off Sir Francis Drake Blvd. That local familiarity matters when a 1960s hillside home needs floor leveling before cabinets go in, or when a creek-adjacent lot off Murray Lane triggers extra drainage review from the county.
Styles & brands we work with







Construction Company in Kentfield
A Construction Company doing work in Kentfield needs to understand one thing before swinging a hammer: this is unincorporated Marin, and the county building department runs the show. When you hire Mason Remodeling for a room addition, a structural opening, or a whole-home remodel in Kentfield, we handle the Marin County Community Development permit process from submittal through inspection sign-off. That means plans, engineering where the hillside demands it, and a calendar that accounts for actual county review timelines, not an optimistic guess.
Scope and Allowances, Written Before Demo
Every Kentfield job starts with a written scope of work and an allowance schedule. Cabinet allowance, countertop allowance, fixture allowance: each one gets a number you approve before we order anything. If you’re looking at a kitchen remodel in Kentfield, expect the final number to land between $14,000 and $45,000 depending on layout changes and finish level. A smaller kitchen refresh runs closer to $9,000 to $20,000.
Hillside Framing and Drainage
Kentfield lots slope. A lot. That means floor leveling, retaining details, and drainage plans show up in more projects here than in flatland Marin towns like Corte Madera. We budget for that in the initial written price, so a sloped subfloor off Sir Francis Drake Blvd doesn’t become a surprise change order three weeks into the job.
Remodeling Contractor in Kentfield

A Remodeling Contractor working in Kentfield is really managing three things at once: the building, the county, and your calendar. Mason Remodeling does all three without drama. Bathroom remodels in Kentfield typically run $9,000 to $28,000, with smaller baths and tub-to-shower conversions starting around $5,000 to $12,000. Whole-home remodels and additions climb from there, $45,000 to $130,000 for an addition depending on square footage and site conditions.
Kitchens and Baths, Done to Kentfield Standards
On a sloped lot off Sir Francis Drake Blvd, our crew took a dated Kentfield kitchen down to studs. We re-leveled the subfloor, ran new rough-in for the sink and island, and handled the county permits through inspection sign-off. The homeowners chose Wellborn cabinetry with a Cambria quartz top, and because the scope of work and allowances were set in writing up front, the only change order was a hidden dry-rot repair found when the old counters came out. That’s how a Kentfield remodel should go.
Written Price Before Anything Gets Unpacked
We don’t do verbal estimates that grow by the week. You get a written price before any work starts, full stop. If something changes mid-project, you see the change order in writing and approve it before we proceed. No surprise invoices, no “we’ll figure it out later.”
Trusted Brands We Service in Kentfield
Kentfield homes deserve professional-grade materials, and we spec them by name. We regularly install KraftMaid and Wellborn cabinetry, Cambria and Silestone quartz surfaces, and Kohler, Moen, and Toto fixtures. For roofing work we use GAF, CertainTeed, and Owens Corning. For hardscape and driveway projects, Belgard, Unilock, and Techo-Bloc. And when site concrete or footing work is part of the job, we trust Sakrete bagged mixes for small pours and Sakrete’s engineered solutions for post bases and anchoring. We order local where possible and keep common finish components stocked with our Bay Area suppliers, which means fewer delays when a Kentfield job needs a matching Schluter strip or a specific Cambria slab pulled from inventory.

AfterCommon General Contractor Problems We See in Kentfield Homes
- Verbal walkthrough pricing. A contractor walks the rooms, names a number from memory, and three weeks later the hillside framing reality shows up as a five-figure change order. We price off a written scope and an allowance schedule, so the number you approve is the number you plan around.
- Skipped county permits. Kentfield is unincorporated, so interior work still falls under Marin County Community Development. Skip the permit on a remodel, and when you go to sell or refinance, the unpermitted square footage becomes a problem. Worse, you lose inspection leverage when rough-in has to be opened back up.
- Calendars that ignore plan review. Marin County plan review takes the time it takes. A contractor who promises a two-week start on a Kentfield addition without accounting for drainage and geotech review is setting you up for a stalled site. We build that time into the schedule from the start.
- Wet-season site access. Kentfield’s winter rains turn hillside work sites into mud. We sequence exterior-related work around the wet months where possible, and we flag it in the written timeline so your punch list doesn’t drag into the next rainy stretch.

What moves the number on a Kentfield job more than anything is site conditions: slope, drainage, access, and what’s hiding behind the walls. A kitchen on a flat, single-story Kentfield lot off College Avenue will price differently than a hillside remodel off Sir Francis Drake Blvd that needs retaining and geotech review. Every written price we give already accounts for those conditions, because we walk the site and look. Call (803) 680-2547 to get your specific number.

FAQs About General Contractor in Kentfield
Building permits for Kentfield are issued by Marin County Community Development, because Kentfield sits in an unincorporated part of the county. That means plan review happens through the county system, not a city building department. For a kitchen or bath remodel with no structural changes, plan review is usually straightforward, but anything touching drainage, retaining, or a hillside lot can add a few weeks to submittal. We handle the permit package, respond to county comments, and build the review timeline into your written schedule. Call (803) 680-2547 and we’ll walk you through what applies to your specific project.
A kitchen remodel in Kentfield runs $14,000 to $45,000, while a bathroom remodel runs $9,000 to $28,000. The biggest cost drivers here are site conditions first: hillside lots off Sir Francis Drake Blvd often need floor leveling, drainage work, or structural details that flat-lot homes in nearby Larkspur don’t. After that, it’s finish level. Cambria or Silestone quartz with custom Wellborn cabinets costs more than stock options, and your written allowance schedule will show exactly where those dollars sit. The best way to get your number is a free site walk, which we’ll schedule at (803) 680-2547.
Every change order is written, priced, and approved by you before the work proceeds. No exceptions. If we open a wall and find dry rot, you see the repair cost in writing and you decide. What you never get is a surprise line item on the final invoice. That’s the Mason Remodeling standard on every Kentfield job, and it’s why our contracts state plainly what’s included, what’s excluded, and how change orders work. Questions about a specific scope? Call (803) 680-2547.
Yes, though hillside lots add planning steps. A garage conversion in Kentfield typically runs $30,000 to $80,000, while an ADU construction starts around $90,000 and can reach $220,000 depending on site work, foundation design, and utility runs. Marin County will want to see drainage and geotech documentation on steeper lots, and some Kentfield parcels near creeks or steep slopes have additional setback and grading rules. We handle the county submittal, engineering coordination, and construction in one written proposal. Call (803) 680-2547 to talk through your lot.
A standard kitchen or bath remodel in Kentfield typically runs 6 to 10 weeks from signed contract to final inspection. Additions and ADUs run longer, usually 4 to 8 months depending on county plan review and site conditions. The variable for Kentfield specifically is the wet season: exterior-related phases like foundation work, drainage, and stucco get sequenced around winter rains whenever possible, which is why we plan those jobs with the calendar in the written schedule. You’ll know the timeline before you sign. Call (803) 680-2547 for a written estimate and schedule.
