Why San Mateo Homeowners Call California Drain Experts
San Mateo’s older neighborhoods have clay side sewers from the 1910s through the 1950s, under some of the largest street trees on the Peninsula. Roots are the main cause of backups there.
Like most Peninsula cities, the homeowner is generally responsible for the private side sewer, and many Bay Area cities now require lateral inspections at sale or major remodel. A camera inspection tells you where you stand.
Eichler homes in the Highlands have drains running under slab floors, where problems are harder to reach. We film the lines before anyone suggests breaking concrete.
Shoreview and the neighborhoods near the bay sit on low, filled ground with a high water table.
Restaurants downtown and around Hillsdale need grease lines and traps kept clear.
Selling or remodeling in San Mateo? Ask whether a private sewer lateral inspection is required. We can film the line first.
