"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 was a pro from day one. He carefully analyzed the entire situation and formulated a solution almost as quickly as he was explaining his end goal. Not only was his answer the best I had been proposed for a new water line, it was actually only slightly higher than just getting the new line to the house, period. Ty also allowed for bypassing any old iron piping, giving me a path directly inside the house. Although I eventually opted for a new sewer line as well, the additional cost involved was well worth it! I highly recommend Ty’s services to anyone needing plumbing work."

"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

There are several homemade solutions for clearing a clogged sink that don’t involve pouring harsh chemicals down your drain. Start by pouring hot (but not boiling) water down the drain. This can help dissolve and flush away grease and gunk. A splash of dish soap down the drain can also cut through fat and make it easier to clear the drain. For a more stubborn blockage, grab a plunger and give it a few firm pumps to dislodge the clog.

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).

If you’re wondering whether rats can come up the toilet, the unfortunate answer is yes, it’s possible, though it’s extremely rare. These rodents are excellent swimmers and can travel through sewer pipes in search of food, and they may follow plumbing lines leading to your home if they’re drawn by the scent of scraps and waste. The toilet’s U-bend holds a small pocket of air, which can help a rat catch its breath before making its final push into your bathroom. While more common in cities with larger rat populations, this can happen anywhere with connected sewer systems; sealing entry points and keeping drains clean can help reduce the risk.

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.

If your drain doesn’t have metal crosshairs or crossbars, you should use a tub drain extractor. These tools create a grip on the drain so you can turn it using a 1/2-inch ratchet drive, drain key, or wrench. Your drain may not have crosshairs if it's old and broken.
