Most homes only need it when a drain slows or backs up. Kitchens with heavy grease, older cast iron pipes or tree roots nearby may benefit from a yearly cleaning.

Call a plumber if a drain stays slow after one try, more than one fixture is backing up, or the clog keeps coming back. Chemical cleaners can damage older pipes.

One slow drain is usually a local clog. If several drains back up, or you smell sewage, the main line may be blocked or damaged. A camera inspection shows which.

Grease, food scraps and soap build up on the pipe walls over time. Running hot water and using a drain strainer helps, but a buildup may still need professional cleaning.

A snake opens a path through a clog. Jetting washes the full inside of the pipe, so it suits grease and recurring clogs. We pick the right tool for each job.
