Sewer Cleaning FAQs, answered by experts

The cost to unclog a drain varies based on the location and severity of the clog. For simple clogs within your home, such as in a sink, toilet, or shower, hiring a plumber typically costs between $110 and $350, with an average of around $200. Snaking a toilet or sink usually costs between $110 and $275, while a bathtub or shower clog costs about $225.

For a more serious clog in the main sewer line, the cost is higher. Clearing a main line clog generally costs between $200 and $600, with an average of about $380. However, prices can range from as low as $100 for snaking a minor clog to over $1,600, particularly if advanced methods like video inspection and hydrojetting are needed for a large or hard-to-reach blockage. Some severe main line clogs can cost upwards of $1,000 to clear depending on factors like the cause of the clog, its distance from an accessible cleanout, and whether the pipe is located beneath an occupied space (e.g., in an apartment building). You may be able to save money on minor clogs by using a drain snake or bladder yourself.

Unlike regular cleanings, snaking your sewer line should be done as needed. There’s no reason to snake your sewer line if you don’t have any noticeable issues, like slow drainage or plugged drains. You can add it to your regular sewer cleaning checklist as a prevention method (on the same 18- to 22-month schedule), but it’s not always necessary. 

Costs range from $200 to $600, depending on the severity of the blockage and access difficulty.

A sewer line should be cleaned at least once every 18 to 22 months. The process takes about 30 minutes or up to 5 hours, depending on the size of the line, how easy it is to access, and how long it’s been since the previous cleaning. If your sewer line hasn’t been cleaned in a couple of years or you don’t even know the last time it’s been cleaned, it’s time to call a pro.

You should hire a sewer service professional to unclog a main sewer line with tree roots. Tree roots can grow into the main sewer line, and this problem requires a specialized hydro jet, or rooter, that is powerful enough to clear the roots. The tree can also damage the main sewer line, and a professional will need to make repairs or replace the damaged sections. Sewer line replacement costs about $60 to $250 per linear foot.
