Why Sawyer Remodeling Is Mill Valley’s Preferred General Contractor Company

Mill Valley homeowners keep hiring us for one reason: we put the price in writing before a single tool gets picked up. That’s The Relay Visibility Guarantee, and it’s been our standard since 2005, when Sawyer Remodeling joined the Relay Home Co. family. Live arrival time, photo updates before and after, and a digital invoice you pay from a link. No invoice surprises, no ghosting between visits.
Luca Romano, who runs our General Contractor team, insists on background-checked, uniformed crews on every Mill Valley job. You know exactly who is walking into your home before they arrive. Our Mill Valley projects come with the 365-Day Done Right Promise: if it’s not done right, we make it right, backed in writing. Every repair also carries a written guarantee and a free second visit if it fails. That’s not an upgrade. It’s the default.
We work across Mill Valley: Sycamore Park, Tam Valley, Strawberry, Homestead Valley, and the hillside streets off Cascade Drive. When you call, a live person answers. Not a voicemail loop. Not a callback queue. After 20 years of remodeling work in the Bay Area, we’ve learned that Mill Valley homeowners want specifics, not vague promises.
Styles & brands we work with







Licensed General Contractor in Mill Valley
Licensed General Contractor work in Mill Valley means exactly that: a state-licensed company that pulls permits, passes inspections, and carries insurance on every job. When you’re planning a remodel on a sloped lot near Blithedale Canyon or Miller Avenue, the City of Mill Valley’s building department often requires geotechnical review and hillside grading sign-off before framing can start. Our team handles that paperwork, schedules the inspections, and keeps the draw schedule moving. Typical Mill Valley permitting adds 2 – 6 weeks to a project calendar, and we build that into the timeline upfront rather than letting it ambush you later.
Scoping and change orders
We scope every Mill Valley job the same way: open the wall before we price it. That’s how you avoid the surprise change order mid-job. If a subfloor is out of level or drainage needs re-routing, we write it into the scope and show you the number before proceeding.
Allowances done right
Material allowances for KraftMaid cabinets, Cambria counters, and Kohler fixtures are listed as documented line items, not a fixed lump you can’t see into. Upgrades get priced before they happen.
Residential General Contractor in Mill Valley

Residential General Contractor work in Mill Valley covers Home Renovation in Mill Valley including kitchens, baths, whole-home remodels, room additions, ADUs, garage conversions, and decks. The big difference between us and a handyman is the permit pull and inspection pass. Mill Valley’s Planning and Building departments review everything from foundation tie-downs on hillside additions to drainage plans on Tam Valley homes. We handle that entire process so you’re not calling the city to chase a permit number. Home additions in Mill Valley run $45,000 – $130,000 depending on size and hillside foundation work; an ADU typically lands between $90,000 and $220,000 when you factor in utility connections and geotech.
Whole-home and hillside work
On a hillside property off Cascade Drive, our crew took a 1950s kitchen down to the studs and found the subfloor out of level by nearly an inch across the room. We re-leveled it and re-ran the rough-in for a relocated sink before hanging KraftMaid cabinets.
From permit to punch list
We wrote the leveling and plumbing relocation into the scope as a defined change order, priced the Cambria counters and backsplash as separate allowances, and walked the homeowner through the inspection sign-off before closing up the walls. That’s the sequence on every Mill Valley residential job: scope, price, permit, build, inspect, close.
Trusted Brands We Service in Mill Valley
We work with manufacturer-backed materials across the full remodel: Cambria and Caesarstone countertops, Kohler and Moen fixtures, GAF roofing, James Hardie siding, KraftMaid and Wellborn cabinetry. For Mill Valley homeowners, that means you choose from proven brands with real warranties, not mystery suppliers. We also coordinate with prefab partners like Abodu and Cover when an ADU or accessory structure makes more sense than a stick-built addition on a tight sloped lot. Local project managers keep Mill Valley jobs stocked and moving without waiting on order delays.

AfterCommon General Contractor Problems We See in Mill Valley Homes
Here’s what we run into most often on Mill Valley projects, and how we handle it:
- Hillside drainage surprises. Much of Mill Valley’s housing stock sits on sloped lots, and many older homes lack proper surface drainage or retaining walls. When we open a wall or trench a foundation, we check drainage first, not after the framing is up.
- Out-of-level subfloors. Flats homes built in the 1950s and 1960s often have floors that have settled unevenly. We catch that during demolition and re-level before cabinets or tile go in.
- Geotechnical and grading triggers. The City of Mill Valley’s building permit process often pulls geotech review on hillside additions. We scope that at the start so it doesn’t stall the schedule mid-job.
- Undocumented previous work. Older Mill Valley remodels sometimes have electrical or plumbing that was never permitted. We flag it, bring it up to code, and document the fix rather than hiding it behind drywall.
Pricing for General Contractor in Mill Valley, CA
Mill Valley’s market prices skew toward the higher end of Bay Area ranges because of slope, permitting, and the age of the housing stock.
