Step by step
Note symptoms: multiple drains backing up, gurgling toilets.
Locate the sewer cleanout (usually a capped pipe near the foundation).
A pro feeds a motorized auger through the cleanout to the main line.
Ask about a camera inspection to identify root intrusion or pipe damage.
Consider annual preventive snaking if you have mature trees near the line.
Questions to ask your pro
- Are you a licensed plumber?
- Do you recommend adding a camera inspection to check for root intrusion, pipe offset, or collapse?
- Where is my sewer cleanout, and is it accessible without excavation?
- If you find a collapsed or severely damaged section, what are the repair options and rough cost range?
- How long should the line stay clear after this service under normal conditions?
- Do you offer a service guarantee, and what does it cover if the clog returns quickly?
- What early warning signs should I watch for to know the blockage is recurring?
