"From the time I submitted the request on HomeAdvisor, they came out within two hours. Jeremy, the technician was very professional, identifying the problem, and recommending the solution. He was able to correct the problem within an hour timeframe and was able to show me on his scope the inside of the sewer line. He did a great job of explaining the problem in terms I could understand, and cleaned up thoroughly prior to leaving. I would definitely use his service again should I need it!"

"Professional and honest service. Michael is the sole proprietor of this local business. He knows his stuff but will not try to scare you into buying more than you need. We paid him to come out and give us a thorough diagnostic of the problem with our sewer pipes. The price I paid for him to diagnose my pipes was fair and I hope to hire him to do the actual fix."

"The crew who came to the house included: Chris, Josh, Christian and Jeff. They were all very professional and they explained very clearly what work needed to be done and where they would need to cut into walls and ceilings. We have a 3 bathroom house with a full finished basement. The crew attempted to make easy cuts for me to repair. The house was as clean as can be expected after two days of work. The job was done completely and thoroughly. We had an issued with the shut off valve and they returned the next day to fix our issue and Josh came out he was professional and friendly. I would definitely hire them again for any plumbing problem. Robert"

"Ty Sarkinen was absolutely wonderful; courteous, talented at his craft, thorough, and neat/clean. I have not had a better experience with any contractor in many, many years. What he charged for the work was extremely reasonable. He was on time, did the work with an upbeat attitude, and I totally appreciated all he did and said. Sarkinen is GREAT!"

"He was on time and came after regular work hours to fit me into his schedule and did not charge for after hour regular service. He gave me an up front estimate and held to it....he diagnosed the problem and tried ti solve the issue without digging up the drain line....unfortunately I have to dig up a section where he believes where the break in the drain line is located. He used video, root cutter, snake and drain line locator."

Sewer Cleaning FAQs, answered by experts

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.

Yes, sewage smells can originate from a floor drain. If the P-Trap in the floor drain dries out or if there's a clog or other issue in the plumbing system, sewer gasses can escape through the drain, causing nasty odors. Regularly pouring water into the drain helps maintain the water seal and prevent those smells, but if the smell persists, you should have a plumbing professional inspect the drain for potential problems.

If you’re not using a septic system, problems with your home’s plumbing won’t cause this—it’s a city problem. A large blockage in the municipal sewage lines may cause those lines to back up into your home. This is extremely unpleasant and can be a serious health risk due to bacteria and other contaminants. If this occurs, call a pro (or your city) immediately.

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.

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