1440 N. Main St. -- 1913
Mauzy Plumbing was Walnut Creek’s longest-operating family-owned
business when it closed after 98 years in 2011. The family started business
in Oakland just after the 1906 earthquake, then moved to Walnut Creek in
1913, eventually to the site across Main Street and next to the former Walnut
Creek Meat Market. Four generations of the family ran the business.
