"All I needed was a replacement for a broken, rusted toilet flange that was set in cast iron. The technician was very professional, and the quality of the work was excellent—I could never have done it myself. I gave 4 stars instead of 5 only because of the cost ($650). To be fair, I didn’t get any other estimates, but it did seem a bit expensive for a job that took only one hour."

"Excellent. I called Ferris Plumbing on a Thursday afternoon and left a message. Matt returned my call the next morning. After I explained the problem, Matt said he would try to get to me that day (Friday), but he may not be able to. Meanwhile, he suggested not using that toilet. He called later that day and said he couldn't make it, but would be able to on Monday. He called me on Monday morning to confirm that he would be coming and gave me a estimated time of arrival. Matt wasn't able to come himself, but two of his plumbers arrived mid-morning. I explain all of this because Matt's communication was OUTSTANDING. I always knew the status and I knew he would be arriving as soon as he could. His two plumbers were also excellent and efficient. They replaced the toilet flange and gasket, and remounted the toilet without needing to disturb the downstairs ceiling. I should mention that the toilet is the original installation of 48 years ago. The original gasket was completely disintegrated to the point that only few small fragments of it were left. They were also very careful to protect the carpet just outside the bathroom by placing a drop cloth to protect it. Their service and work was EXCELLENT. We are considering remodeling that bathroom and Ferris Plumbing will certainly be our first choice to do the work. I highly recommend (Matt) Ferris Plumbing."

Sewer Cleaning questions, answered by experts

Unlike regular cleanings, snaking your sewer line should be done as needed. There’s no reason to snake your sewer line if you don’t have any noticeable issues, like slow drainage or plugged drains. You can add it to your regular sewer cleaning checklist as a prevention method (on the same 18- to 22-month schedule), but it’s not always necessary. 

The type of clog in your sewer main determines the required cleaning method. Different types or methods of sewer main cleaning require various tools like chemicals, mechanical removal, or a combination of both. Some of the most common types of sewer main line cleaning include:

  • Minor debris removal: $100–$600

  • Tree root removal: $100–$1,000

  • Trenchless pipe repair: $60–$250 per linear foot

  • General line repairs: $1,000–$4,000

  • Full pipe replacement: $3,000–$25,000

If you’re not using a septic system, problems with your home’s plumbing won’t cause this—it’s a city problem. A large blockage in the municipal sewage lines may cause those lines to back up into your home. This is extremely unpleasant and can be a serious health risk due to bacteria and other contaminants. If this occurs, call a pro (or your city) immediately.

Clearing typically takes 1-2 hours, depending on the blockage size and location.

A sewer line should be cleaned at least once every 18 to 22 months. The process takes about 30 minutes or up to 5 hours, depending on the size of the line, how easy it is to access, and how long it’s been since the previous cleaning. If your sewer line hasn’t been cleaned in a couple of years or you don’t even know the last time it’s been cleaned, it’s time to call a pro.
