"I had a great experience with The Sewer Boyz when they came out to locate and repair my sewer line. Jonathan made the whole process smooth and reassuring from start to finish. He took the time to explain how he would locate the line, clearly identified the problem, and walked me through the repair options without any pressure. His knowledge and professionalism immediately gave me confidence. The repair was done efficiently and with great attention to detail, and he made sure everything was working perfectly before leaving. What really stood out was how respectful and personable Jonathan was. He treated my home with care, cleaned up thoroughly, and made sure I understood everything that was done. I truly appreciate his honesty and quality of work. Highly recommend this company. Definitely a 5-star experience!"

"We had a major sewer main blockage at our home and it turned out to be caused by heavy root intrusion. Mike, the technician, did an excellent job diagnosing the issue quickly and explaining everything in a way that was easy to understand. He showed us what he found and recommended hydro jetting to properly clear the line. Mike was very professional, thorough, and made sure the sewer line was completely cleaned out before finishing. The hydro jetting worked perfectly and everything has been flowing great since. On top of that, the price was very reasonable for the amount of work and the level of service we received. I really appreciate the honesty, quality work, and peace of mind. Highly recommend Mike if you?re dealing with a sewer blockage!"

Sewer Cleaning FAQs, answered by experts

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.

Depending on the home, wastewater either goes into a septic tank and seeps back into the backyard or is sent via sewer system to a local sewage-treatment plant. Septic systems naturally separate different components of the waste so that it can naturally and safely disperse it. They are usually reserved for homes not served by a municipal sewage department (like rural homes). A treatment plant, on the other hand, speeds up that process through screening and purification.

To prevent drain clogs, perform regular maintenance and cleaning. Avoid disposing of substances like grease or coffee grounds down the sink. Additionally, installing and routinely using drain strainers can help catch debris and prevent blockages from forming.

As a preventative measure, hydro jetting should be done every one to two years. However, the best practice is to hydro jet your sewer line once per year. The ideal frequency depends on several factors, including the age and condition of your pipes, how prone they are to clogging, how often the sewer line is used, and the type of waste disposed of in the system. If you frequently experience clogs or are unsure, it's best to ask a licensed plumber for a recommendation specific to your plumbing system.

With a one-way cleanout, you can access your sewer line from one direction. Depending on the way it curves, a plumber can either access the side of the pipe that goes into your home or the side that goes to your yard. On the other hand, two-way cleanouts allow pros to access both sides of the sewer line, thanks to their dual-pipe design (they’re usually U-shaped).
