"We had an internal house line leading to the sewer plugged on a Sunday. We couldn't run any water in the house without it coming out of the drain and into the basement. Based on all the positive reviews I read of KJM plumbing, I called Kurt and he was here within 20 minutes with his machine and cleared the clog, which took about an hour. Pleasant, polite man. The price was reasonable for a weekend emergency call. If I need a plumber again, he'll be the first one I'll call."

Sewer Cleaning FAQs, answered by experts

The cost to clean a sewer line is about $370, ranging from about $190 to $550 on average. The specific cleaning method and the problem's severity will impact the project's overall cost. Some of the most common sewer line cleaning methods include:

  • Snaking or rodding: $100–$250

  • Hydrojetting: $350–$600

  • Chemical treatments: $600–$1,000

  • Repair or replacement: $1,000–$7,500

Yes, many services include camera inspections to identify the cause of the blockage. Confirm with your provider.

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.

When hiring a sewer line company, you need to consider more than just the quoted price. Make sure to check that the company or contractor is licensed, certified, and insured to protect you both. Check for positive reviews, and you can even request references for extra peace of mind. 

To find the best contractor, you might also want to consider how long the company has been in business doing sewer line cleaning and if they’ve won any industry awards for their work and service. Review potential contracts closely, and look for transparent pricing.

Your sewer line can get grimy quickly. To prevent sludge buildup in your sewer line, pour a mixture of 1/3 cup of vinegar and 1/3 cup of baking soda down each drain in your home once a month. After about 30 minutes, flush the drain with hot water.

Some plumbers recommend 3/4 cup of bleach instead to clean any germs and bacteria that may build up in your sewer line. But this won’t break down any active clogs, and it cannot be combined with vinegar, as the mixture will create a toxic, hazardous gas.
