Much of Northridge was built out in the postwar boom of the 1950s and 1960s. Homes from that era often still have their original clay or cast-iron sewer laterals, and those pipes are now 60 years old or more. Clay joints let roots in, and cast iron scales and cracks from the inside, so root intrusion, offset joints and slow drains are the usual calls here.

Northridge sits on the flat inland basin, where most laterals run a fairly short distance to a main in the street. Mature street trees and driveways over the line are the usual complications, and they are a big part of why homeowners ask about trenchless repair.

Not sure what it will cost? Read the Los Angeles County sewer repair cost guide.

In Northridge, the public sewer mains are run by LA Sanitation and Environment (LASAN), the City of Los Angeles sewer agency. As a rule in Los Angeles County the property owner is responsible for the private lateral, the pipe from the house to the connection at the main, so a backup or a root intrusion in that section is a homeowner repair. Confirm where your responsibility ends with LA Sanitation (call 311 or LASAN) before work starts, and ask the contractor who pulls the permit.

1 company listed in Northridge carry the Trenchless badge: Valley Sewer. Trenchless methods such as pipe lining and pipe bursting can avoid digging up a driveway or mature landscaping, but they depend on a camera inspection showing a pipe that can take a liner or be burst along its path.

Before you hire in Northridge, check the contractor's license with the California CSLB, ask whether the price includes the permit and the cleanout, and keep a copy of the inspection video.
