Sewer Repair in San Mateo, CA

Sewer repair in San Mateo ranges from $1,000-$4,000 for spot repairs to $3,000-$25,000 for full sewer line replacement. Trenchless methods (pipe lining, pipe bursting) often cost $4,000-$10,000 and avoid digging up your yard. Get a camera inspection quote first.

Warning signs include: multiple drains backing up simultaneously, gurgling sounds from toilets, sewage odors in your yard, soggy patches or sinkholes near the sewer line, and unexplained increases in your water bill.

Trenchless methods repair or replace your sewer line without digging a trench through your yard. Pipe lining inserts a resin-coated liner inside the existing pipe; pipe bursting pulls a new pipe through while breaking the old one apart. Both minimize landscaping damage.

Standard homeowners insurance in CA typically does NOT cover sewer line repair or replacement. Some insurers offer separate sewer line coverage as a rider for $5-15/month. Check with your agent — it's worth adding if your home has older sewer lines.
