Custom Mill Valley Concrete & Masonry was founded in 2020 by tradespeople who had spent years working on homes throughout Marin County. They saw the same problem come up again and again - good homeowners getting poor work from contractors who didn't understand the local terrain, the older housing stock, or what it actually takes to do masonry right on a hillside lot.
Mill Valley is not a typical suburban market. Homes here sit on steep, wooded lots near Mount Tamalpais. The winters are wet - close to 50 inches of rain in a heavy year - and the clay soils move. Foundations shift. Retaining walls crack. Chimneys take on water. These are not generic problems, and they don't respond well to generic solutions.
Since 2020, we've worked on homes throughout Mill Valley, Sausalito, San Rafael, and across the Bay Area. Our crew handles everything from foundation repair to chimney work to outdoor kitchens, and we do it with the kind of care you expect when the person doing the work is also your neighbor. Every estimate is free. Every job gets a walkthrough at the end.
Every job site is cleaned up at the end of each day. We protect your landscaping, driveway, and surfaces during the work - not just after the work is finished.
Contractor no-shows are one of the most common complaints in this trade. We confirm appointments, arrive on time, and communicate any changes the same day.
You get a single point of contact from estimate to final walkthrough. We don't hand off your job to a subcontractor you have never met.
Marin County's clay soils, wet winters, and hillside terrain shape how masonry work gets done. We factor those conditions into every estimate and every repair.
State-licensed and fully insured masonry contractor operating under California contractor licensing requirements. We carry a California C-29 Masonry contractor classification. License information is available on request before you sign anything.
We carry general liability insurance and workers compensation on every project. If something unexpected happens on your property, you are covered. Ask for proof of insurance before any crew sets foot on your lot - we have it ready.
We have been working on homes in Mill Valley and across Marin County since 2020. Local experience is not a marketing phrase here - it reflects how we think about access, soil conditions, permitting, and scheduling on every job we take.
Based in Mill Valley, we serve 12 cities and communities across Marin County and the greater Bay Area.
