Sewer Line Repair in Rockville, MD

Sewer line repair costs $1,000–$8,000 for trenchless methods and $3,000–$15,000 for full excavation replacement. Trenchless pipe lining (cured-in-place) costs $80–$250 per linear foot. Camera inspection to assess the damage costs $100–$300 and should always precede repair quotes.

The most common causes are tree root infiltration, pipe corrosion (cast iron and clay pipes older than 30 years), ground settling, grease buildup, and improper flushing of non-degradable materials. Homes built before 1980 with clay or cast iron sewer lines are at highest risk.

Trenchless sewer repair includes two main methods: pipe lining (inserting a resin-coated liner that hardens inside the old pipe) and pipe bursting (pulling a new pipe through while breaking the old one). Both avoid the need to dig up your yard, driveway, or landscaping.

Signs of sewer line failure include: multiple slow drains throughout the home, sewage backup in lower-level drains, gurgling sounds in toilets, patches of unusually green or soggy grass in the yard, foundation cracks, and sewage odor inside or outside the home.
