Sewer Cleaning FAQs, answered by experts

There are many things that could cause your basement floor drain to back up. One significant cause of a drainage backup is flushing non-flushable items, such as wipes, paper towels, and facial tissue. Other causes of a backed-up basement floor drain include tree roots impeding the drain pipe or an accumulation of hair, oil, and grease. 

Avoid flushing non-degradable items, schedule regular inspections, and address minor clogs promptly.

Homeowners insurance usually doesn’t cover sewer backups because it’s typically an avoidable problem with proper maintenance. The only exception would be if the backup is occurring because of local flooding and only if your city uses a combined drainage system for stormwater and sewage. If that’s the case, your policy should cover any resulting damage.

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.

If you’ll be digging up your floor to get access to your pipes when putting in a sewer backflow preventer, this would also be a good time to take care of any other plumbing issues or renovations. For example, you could install additional pipes for a basement bathroom. Since the floor will be sealed over with concrete when you’re done, now’s a good time to take care of those bigger tasks.
