Sewer Line Repair & Replacement in Westlake, Daly City, CA
Westlake's street trees have had decades to reach the laterals running beneath them, and root intrusion is the dominant sewer problem in this neighborhood. Roots enter at joints, which means clearing them removes the mass but leaves the entry point untouched.
Why do roots keep coming back after clearing?
Because clearing removes the root mass, not the crack or joint they entered through. Until that entry point is repaired or lined, they return on a fairly predictable cycle.
