When the clog keeps coming back

Roots grow into the joints of old clay sewer lines, and snaking only clears them for a while. Hydro jetting removes more, and a camera inspection shows whether the line needs repair. Compare drain cleaning cost, hydro jetting cost and sewer camera inspection cost.

Common questions

Why does my basement floor drain back up?

A basement floor drain is usually the lowest drain in the house, so a main line clog shows up there first. Have the main sewer line cleared and inspected.
