"They did a great job. It was quite an undertaking, digging a trench in the basement to re-route the sewer line, but they were efficient and courteous and it ended up being well worth the relatively short inconvenience. Their bid was very competitive and they gave a written guarantee."

"I had a clogged drain that no amount of plunging could get rid of. I called several companies. I initially went with Mr Rooter because they were the only ones that could make it out that same day. Glad I did. The technician was very pleasant and he took his time to explain all the steps he was doing and let me watch as he put a camera down the drain and showed me on the screen where the clog was and all the build-up in the pipes. He then brought in a high pressure washer and I watched on the screen as he cleaned the pipes all the way down to where it joined up with the main sewer line. I initally thought the estimate was a little high, but not after watching all that they (his supervisor also showed up after an hour to help out) did."

"James came out and quickly and efficiently took out old toilet, replacing with a new one. Polite and got right to work. I was impressed with his skill and with the speed that he got the project done. Leaving everything nice clean and beautiful. I like the way the company sends a pic of the person coming out, and felt safe with him being here. I’ll def use this company again for even bigger projects."

"Warren showed up on time, was respectful of our home- wearing shoe covers and cleaning up after himself, & flushed the water line and faucet which fixed the problem. He was honest and quick. Would definitely recommend D&F. We have used them before and have always been satisfied."

"I put in a request for septic tank pumping and the first contact (from other company) was crazy high. A Affordable Septic gave a quote that was extremely reasonable and they surely live up to the name. Marty came out this morning; on time or even a bit early. He was extremely kind and helpful. I would definitely recommend this company for anyone needing septic service. I pray God's Blessings on this company and its employees. John 3:16"

Sewer Cleaning FAQs, answered by experts

A sewer cleanout typically looks like a white or gray PVC pipe with a removable cap. It's often located either in your yard or basement, depending on your home's plumbing configuration. The cleanout pipe is designed to provide easy access to your sewer system for maintenance and inspections. It may be flush with the ground or slightly elevated, making it distinguishable from other pipes. When you remove the cap, you can access the sewer line directly or determine its direction, which can be helpful when you need to locate your sewer line from your house to the street.

Cat pee has a strong ammonia-like smell, so if you smell cat pee but don’t have a cat or don’t suspect your cat has any accidents, there could be other issues at hand. Aside from pet urine, your house may smell like cat pee from leaking freon from an old fridge, mold, spilled cleaning supplies, or even outside odors from nearby farms.

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. 

Some experts estimate that descaling your cast iron pipes can extend their lifetime by upwards of 50 years, although there’s not a lot of research to prove it. But we do know that without proper maintenance, cast iron pipes can quickly rust—leading to more expensive issues like burst pipes or main line clogs.

The average cost to snake your main sewer line is around $250 for a simple snake. Most sewer line specialists charge between $45 and $200 per hour for main sewer line snaking, so the time involved plays a major role. The price you’ll pay will depend on the severity of the clog, the item causing the backup, how long it takes to remove the item, and more. A more severe issue that requires unclogging a main sewer line will cost $3,100 on average.
