"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

Knowing the signs can alert you to a clogged drain line. Clogs cause slow drainage or cause no drainage (if there’s a complete blockage). You may also notice foul odors, gurgling noises, water backing up in other appliances on the same line, or a poorly flushing toilet. If you experience any of these issues and think your line might be clogged, call a plumber.

Regardless of the drain cleaner type you choose to use, they all work through chemical reactions that create heat. Thanks to the heat, the clogged hair begins to dissolve until it is able to be flushed away. To avoid clogs in your drain due to hair, use hair catchers and empty them out after every shower.

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

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.

A sewage smell in your crawl space is usually from a damaged or clogged pipe leaking sewer gasses or actual sewage underneath your home, but there are some other common causes. Moisture, from poor or damaged encapsulation or a malfunctioning sump pump, can harbor mold and bacteria, causing a musty smell. Pests can also get stuck in your crawl space and die, which causes a sewage-like odor.
