"John was fantastic. We had a section of sewer pipe that was something called Orangeburg (glorified tar paper form WW2 war shortage era). It was falling apart and had serious roots in it. He took A LOT of time and care and was able to clear the roots mostly out without destroying the rotting pipe, to the point where it will be usable for a few more months. The pipe will need to be replaced, but John bought us A LOT of time on a very expensive future job. He also was able to pinpoint what parts of the yard would need to be dug up and was able to recommend someone. It was obvious he cared about what he was doing and wasn't just in there for a quick payday. HIGHLY RECCOMEND."

"Called quickly to inquire about our plumbing problem, set up an appointment for the next day, and was here on time. Did the work quickly and professionally and came in at a cost under his quote. His quote was also considerably lower than another I had gotten. I will use him again and would recommend him."

Sewer Cleaning FAQs, answered by experts

DIY is not recommended due to safety risks and specialized equipment requirements. Hire professionals for effective clearing.

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).

In most areas, drain cleaning professionals don’t technically need a license, as they aren’t altering your plumbing system in any way. However, we recommend hiring a drain cleaning professional with a plumbing license and certification. Certified plumbers are more likely to provide professional solutions to drain clogs without damaging your system. They’ll also have the diagnostic tools and experience necessary to remove the clog entirely rather than providing a temporary solution, as a handyperson might. Use Angi’s state licensing tool to check your plumber’s professional licenses before hiring.

Snaking a toilet is similar to clearing sinks and bathtubs, but there are unique circumstances where you’d have to drain, disassemble, and remove the toilet to fix the clog. For stubborn clogs in the toilet trap, a toilet auger—designed with a shorter cable and a protective plastic encasing—can navigate the tight bends and clear the clog without risking damage to the porcelain. 

A two-way cleanout can help if there’s already a clog, but the best strategy to prevent one is by not rinsing grease, oil, or fat down your drains, not flushing or rinsing coffee grounds or egg shells down your drains, flushing only human waste and toilet paper (so no diapers, period products, bathroom wipes, or paper towels), and using drain guards on all of your drains.
