"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"

"I highly recommend Tom! He's a perfectionist with his work and very friendly. Anytime I need him, he's there. We own apartments in New England and pipes will sometimes break in the winter. Tom has come in the middle of the night to help out and I couldn't be happier with his service!"

Sewer Cleaning FAQs, answered by experts

The cost to repair a main sewer line clog is about $3,110 on average. The average cost range is  $1,310 to $4,950, but it can go as low as $215 and as high as $9,300 or more. The cost factors for this repair include the severity of the clog, pipe accessibility, video inspection, removal method, permits, pipe material, labor rates in your area, and time of year. Repairs made from outside during the winter can be more difficult due to the frozen ground or during the spring if the ground is saturated from a lot of rain and snow melt.

If used correctly and sparingly, root killer shouldn’t damage your pipes. Make sure to follow the instructions on the back of the bottle or the company’s website to avoid any unintended damages. However, when it comes to copper sulfate, it’s better to avoid it. This type of root killer can damage your plumbing and the surrounding environment.

Sewer gas in any location can cause eye and respiratory irritation if you’re exposed at low levels, or more severe symptoms if you’re exposed at high levels—but fortunately, the fresh air outside means it’s less likely to affect your physical health. However, sewer smells outside can still indicate significant plumbing problems that will need to be dealt with, such as a potentially damaged sewer line or roof vent pipe.

Bleach isn’t likely to help unclog a sewer line. Bleach isn’t useful in this situation because it won’t dissolve the grime and debris in the clog. Instead, you want to use ingredients that will have a chemical reaction to clear out the buildup, like vinegar or salt and baking soda.

In most states, companies that perform sewer cleaning services don’t need specific licensing, but you should always ensure you hire a licensed and certified plumber to get the work done. You can use our state licensing tool to check whether the potential sewer cleaning company holds a plumber’s certification and license. Hiring a certified sewer cleaning services guarantees that the work will be done safely, there won’t be additional damage done to your home, and the problem will be fixed.
