"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!"

"Jose (with JRC Plumbing) did an excellent job replacing my kitchen faucet. He quickly responded to my request and was on time to the job site. He was clean and effecient (everything you hope for in a plumber inside your home)! His attention to the details (making sure the faucet was centered and no smudges) was definately appreciated. I highly recommend Jose for your next job!"

"David came out after hours to clear a badly clogged drain for us, and we couldn?t be more grateful. We had water backing up and were really stressed, but he arrived quickly, was very professional, and explained everything clearly. He used hydro jetting to thoroughly clean the line, and you could immediately tell the difference ? the drain has been flowing perfectly ever since. What really stood out was his attitude and work ethic. Even though it was late, he took his time to do the job right and made sure everything was clean before leaving. Fair pricing, honest service, and top-notch work. Highly recommend David for any drain or sewer issues!"

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.

An active cleaning agent and a drain snake is the best way to clean a main sewer line. You can purchase a regular or enzyme drain cleaner or make a DIY drain cleaner with baking soda. Use your chosen solution at least once a month or as needed to keep your sewer line clear. 

No, you typically cannot use metal detectors to find your sewer line. Most sewer lines are made of non-metallic materials such as PVC, clay, or cast iron, which are not detectable by standard metal detectors. Metal detectors are designed to locate metallic objects, so they won't be effective for identifying the path of a non-metallic sewer line. To locate your sewer line accurately, it's best to use other methods.

Your sewer pro will take about an hour to complete your sewer line camera inspection. However, if your home does not have cleanout access and the pro needs to remove the toilet to access the sewer line, the time to completion will take longer. Note that this estimated time does not include the time for repair, drain cleaning, or any other services you may need. 

No, you should not see water in a sewer cleanout. If you do, it could indicate that you have a block or leak in your main sewer line—which can cause sewage to back up inside your home and potentially flood your yard. Your best bet is to call a local sewer cleaner if you notice any water or sewage around your cleanout.
