Licensed Plumber in San Mateo, CA

Many Peninsula homes in San Mateo still have original pipes from the decades they were built, which is why repiping and sewer work come up so often. San Mateo homeowners who need a licensed plumber can book on NorTech only an independent contractor whose California C-36 license has been checked against the state record, never someone who is still working toward one.

Licensed plumber work in San Mateo

San Mateo: Central Peninsula hub with established neighborhoods and great commute access. Typical homes: Single-family homes, townhomes, condominiums, duplexes, multi-unit properties, and commercial properties. What drives local demand: Pre-rainy season exterior work, earthquake prep, and property investment upkeep. When a project crosses into permitted, structural or code-regulated work, it moves from a smaller handyman job to a licensed plumber.

NorTech connects San Mateo homeowners, including those in Baywood, Hayward Park, Bay Meadows, San Mateo Park, Aragon, and Sugarloaf, with licensed plumbers, and the areas around Central Park, Hillsdale Shopping Center, and the Caltrain station.

The license, and how we check it

California class C-36: Plumbing Contractor

California plumbing contractors hold a C-36 license. Any license number can be looked up on the state licensing board website, and we check status and expiry before a contractor can take licensed plumbing work.
