"Drain was initially cleared using a drain augur, but inspection via camera revealed that additional cleaning was needed. A followup visit happened about a week later to perform a hydro-jet flush and the video inspected now showed a very clean drain pipe. The technician was very professional and explained the steps he was following and what he observed. I would recommend this company for this kind of drain service."

"They did a great job fixing our sewer line. All workers were experts of this trade. They kept all the dust concealed in the areas they had to jack hammer in the basement. They used a window well to bring in their tools and supplies. They didnâ t want to haul the mess through the house. Canâ t say enough about their excellent work. I have already told the neighborhood about their great work. Thanks guys"

"Ongrade plumbing and excavating was a god send. Unbelievable how clean and professional they were from start to finish on my sewer line replacement. They did their best to protect my grass with plywood and did a very good job cleaning up given the huge pile of dirt! Thier pricing was amazing compared to some of the other estimates I received from other company's. Highly recommend to anyone for any of thier home or business plumbing issues"

Sewer Cleaning FAQs, answered by experts

Schedule regular inspections, fix minor issues promptly, and ensure proper drainage.

Knowing the signs can alert you to a clogged drain line. Clogs cause slow drainage or cause no drainage (if there’s a complete blockage). You may also notice foul odors, gurgling noises, water backing up in other appliances on the same line, or a poorly flushing toilet. If you experience any of these issues and think your line might be clogged, call a plumber.

Roto-Rooter does not charge by the hour, so the quote you get after your in-person consultation should cover the whole project. This includes the time it takes a technician to get to your house and the time it takes to complete the job. For context, a plumber will charge anywhere from $45 to $200 per hour, but you may also pay a service fee or flat fee. 

There are a few things that can happen to your sewer system if you don’t fix it. These include rainwater entering it and causing rust and corrosion, dirt and debris leading to blockages, small animals getting stuck inside and clogging your sewer line or entering your home, and shortening the sewer system’s life span. 

Without a cap, nothing prevents toxic and non-toxic gasses like methane and hydrogen sulfide from slowly escaping your sewer system and entering your home and the surrounding atmosphere, resulting in a foul sewer odor throughout your house.

Your sewer pro will take about an hour to complete your sewer line camera inspection. However, if your home does not have cleanout access and the pro needs to remove the toilet to access the sewer line, the time to completion will take longer. Note that this estimated time does not include the time for repair, drain cleaning, or any other services you may need.
