Sewer line repair in Washington, DC
A damaged sewer line can be fixed with a spot repair, a trenchless liner, pipe bursting or an open-trench replacement. Which one fits depends on what the camera shows, how deep the pipe is, and what's on top of it, such as a driveway, trees or landscaping.

Sewer line repair for Washington homes
Sewer repairs are big decisions, so they should start with a camera video and a locator showing exactly where the defect is. One cracked joint near the foundation is a very different job from a line that's collapsed in three places under the street.

Sewer line repair in Washington: what's different
Sewer laterals under D.C. rowhouses are often original cast iron or clay, running under rear yards, alleys or the front sidewalk to the public main. Roots, cracks and joints that separated over a century of settling are the usual failures, and the lateral belongs to the property owner.
DC Water's Clean Rivers tunnels have cut combined sewer overflows, but they don't fix a broken lateral. A camera inspection shows where the damage is and how deep, which decides between a spot repair and lining. Permits come from the D.C. Department of Buildings, and digging in public space needs separate approval.

Why is my basement floor drain backing up?
When water comes up through the basement floor drain, the main sewer line is usually blocked between the house and the street. Stop using water upstairs, then call a plumber to clear the main line. If it happens more than once, a camera inspection shows the cause.

Should you get a sewer scope before buying a home?
For homes built before about 1980, or with large trees in the front yard, a sewer scope is worth it. A standard home inspection doesn't look inside the sewer line, and in most U.S. cities the buyer will own that line, often all the way to the main.
