How much does it cost to unclog a drain professionally?

Professional drain unclogging with Monkey Wrench Plumbing, Heating, Air & Electric is $99 for a single drain under our current promotion (expires 2026-04-01), and you can take $100 off a drain camera inspection when combined with drain cleaning. Total cost can increase if the blockage is severe, recurring, or tied to the main sewer, which may require advanced tools or additional services; final pricing is confirmed after an on-site diagnosis. We clear residential drains across the Tarzana area with trained, uniformed techs who keep workspaces clean. A technician’s tell: if one fixture triggers backup in another, you may be dealing with a main-line issue rather than a simple sink clog.

Costs may be higher when:

• A camera inspection is added for verification or mapping.
• Hydro-jetting is needed to cut grease, scale, or roots.
• Sewer-line repairs or trenchless options are required beyond basic clearing.

Avoid chemical drain cleaners and shut off water to an overflowing fixture before we arrive. <br/> Updated: 2026-03-31 <br/> Need help in Tarzana, CA? Call (818) 330-3351 or book online.
