Sewer Line Repair & Replacement — Los Angeles, CA

Service area covers Los Angeles proper plus the metro suburbs. After-hours is real after-hours, not "we'll get back to you tomorrow."
Scope of work
Sewer lateral problems hit older homes hardest. Anything pre-1970 in most U.S. cities still has either clay-tile or Orangeburg laterals from the original build. Both fail. Tile cracks at the joints; Orangeburg collapses under load.
Diagnosis order: cable first, then camera. Cable clears most active blockages. The camera shows you what's actually happening down there — joint offsets, root invasion, bellies, broken sections.
Repair options depend on the lateral. Spot repair on a single broken section: $3,200–$6,500. Trenchless pipe burst on the full lateral (replaces clay or cast iron with new HDPE): $6,500–$14,000. Open-trench replacement: rare anymore, only when trenchless isn't feasible.
Permit is almost always required. Municipal sewer authorities want to inspect lateral work before backfill. We pull the permit and coordinate the inspection.
