"Amazing Service! My main sewer line backed up late last night, causing a huge mess and a lot of stress. Mo arrived within an hour. He was incredibly professional, quickly diagnosed the problem, and cleared the line promptly. Everything returned to normal quickly, and he cleaned up thoroughly before leaving. The speed and efficiency are appreciated.""

"I donâ t usually rate anyone, but I was so happy with the service that Rojas sewer provided that I needed to rate them. I previously call another service who charge me more money and the job was not done. I called Rojas, and they fixed my sewer line immediately. They even provided me with pictures of the blockage of my sewer. Iâ m very happy with their service."

"Abraham did an excellent job of getting clogged bathroom sink and a shower stall working again. He additionally changed some old pipes in the basement. I particularly appreciate the fact that he took his time to tidy up after self and didn’t leave us with a mess. I would hire him again."

"George responded right away via Angie?s text and then a phone call. Came out the next day to attempt to snake two clogged tubs on second floor of a side-by-side two family home, connected to one sewer line.. Clog was more severe than expected. Came back next day with partner to find pipe where they join but it was behind kitchen cabinet of both homes. Decided to bypass existing line and run new lines from each tub, join them and then drop a sngle pipe to the basement and reconnect to near the main drain. George and his team were professional and communicated in a timely manner. Cleaned up and covered opening with plastic and suggested not to close wall for a week and inspect for any leaks. No leaks so far. Closing walls this weekend. Offered us a great price and an unbeatable 12 month payment plan. Thank you George and team."

Sewer Cleaning FAQs, answered by experts

There is conflicting advice on whether to leave a baking soda and vinegar mixture in a drain overnight. Some sources suggest it can be effective for tough clogs, recommending that you flush the drain with warm water in the morning as part of a monthly cleaning routine. However, other experts advise against leaving the mixture in for extended periods, as its caustic nature could corrode drainpipes if used too often or left in for too long.

It can take anywhere from half an hour to a few hours to fix a main line clog, depending on the cause and severity of it. The job should not take more than a day to complete. Keep in mind that the main line is not the same as your home’s sewer lines (which connect to the main line and run to your house). Your city is responsible for any clogs or damage to the main line itself.

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.

Common drain issues include slow-running drains, whether in a sink or shower, clogged drains, a bad smell, and water backing up into a sink, shower, or bathtub. Causes range from hair, grease, roots, or toilet paper clogging the drainpipes to flooding outside the home, which prevents sewer lines from draining properly.

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.
