"The Sewer Boyz did a fantastic job, the owner Jonathan is very professional on his work and much patience explaining in detail the process. In the past, he’s also done major plumbing, sewer repairs at our rentals. He is very professional and is very clean after all the work is completed. I recommend Sewer Boyz for any plumbing issues anyone might have. Thank you Sewer Boyz for all the hard work you have done for us.."

"The plumber spent a lot of time just trying to figure out the source of the hidden leak. He had a lot of patience. The quality of work was good as was the price. I would definitely hire them again."

"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

It is generally safe to stay in a house that smells like sewage for a short time, but you should get the problem fixed as soon as possible. While the level of sewer gas is usually low enough to only cause minor symptoms, prolonged inhalation can lead to headaches, nausea, or respiratory irritation. High levels of gas exposure can be more dangerous, and high concentrations of methane—a component of sewer gas—can pose an explosion risk in enclosed spaces. If you smell sewer gas in your home, ventilate the area and call a professional to locate, assess, and fix the problem, as it will not go away on its own.

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.

It is safe to flush small amounts of bleach down the toilet. Don’t flush more than ¼ cup of bleach. Instead, consider diluting it and pouring it down the sink drain.

Main sewer lines can clog for several reasons. For example, if you regularly dump oil or grease down your drain, it could eventually block your line. Sometimes, tree roots can penetrate and grow inside old sewer pipes, creating a major blockage. Flushing bulky items (like paper towels, diapers, or baby wipes) can also clog your plumbing system.

If you want to avoid using a snake to unclog a drain, or if you don’t have one, try vinegar and baking soda. Pour 1 cup of baking soda down the drain, followed by 1 cup of white vinegar. Wait for 15 minutes, and then run hot water (but not boiling water) down the drain to see if the clog is clear. Repeat multiple times as needed.
