"Preston came over in an hour after I first reached out regarding a sewer line blockage (and it was on a Sunday). He quoted a really fair price and worked until the clog was freed. He then did a toilet reinstall for next to nothing. He'll be my go-to for any jobs on the future."

"Anyone that needs a clogged drain taken care of, do yourself a favor and call Honest Drain. I called at 7:45 am and the expert was at my home at 9:15 am. I was impressed with how he did such a fantastic job that is usually nasty and he left my bathroom spotless. Less than an hour later, I had my shower back. I have had other companies in the past that advertise with big promises and was disappointed. Hats off to Gianni and Honest Drain. Sincerely, W S in Providence, R I"

"A team member came by on Christmas Eve to help us with a shower drain. We were previously told that all pipes needed to be replaced for roughly $2,000. David found a workaround for $160. United certainly has the expertise and honesty to be my go-to choice in the future. Highly recommend them to others."

Sewer Cleaning FAQs, answered by experts

There are a few things that can happen to your sewer system if you don’t fix it. These include rainwater entering it and causing rust and corrosion, dirt and debris leading to blockages, small animals getting stuck inside and clogging your sewer line or entering your home, and shortening the sewer system’s life span. 

Without a cap, nothing prevents toxic and non-toxic gasses like methane and hydrogen sulfide from slowly escaping your sewer system and entering your home and the surrounding atmosphere, resulting in a foul sewer odor throughout your house.

If methods like hot water or a plunger don’t work on your clogged drain, you can snake your drain to dislodge the plug. This can be a messy process, taking some physical effort and additional time over the other drain-clearing options. You can purchase a drain snake at a hardware store and choose from handheld options or those attached to a drill. Just work slowly, and be ready to call a plumber if you’re unable to reach the clog from your drain or P-trap.

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.

In most areas, drain cleaning professionals don’t technically need a license, as they aren’t altering your plumbing system in any way. However, we recommend hiring a drain cleaning professional with a plumbing license and certification. Certified plumbers are more likely to provide professional solutions to drain clogs without damaging your system. They’ll also have the diagnostic tools and experience necessary to remove the clog entirely rather than providing a temporary solution, as a handyperson might. Use Angi’s state licensing tool to check your plumber’s professional licenses before hiring.

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.
