When you need an emergency plumber or a drain cleaner, call Roto-Rooter Plumbing & Water Cleanup. Your fast & reliable plumber can fix any plumbing problem, including sump pumps, toilet repair, faucet repair, faucet replacement, garbage disposals, water heaters, bathtubs, showers, and outside faucets. Roto-Rooter is best known for drain cleaning & sewer cleaning. We fix drain clogs, clogged toilets or sinks, blockage of main sewer lines, slow draining shower and bathtub drains, sewer lines and leaking or burst pipes. We also specialize in water damage restoration & water cleanup services. We can fix and clean up your flooded basement too. Roto-Rooter is a 24-hour plumber near you and provides emergency service.

"At first the company seemed super helpful. Eric was always pleasant and seemed to be supporting us. HOWEVER, they told us that they were dealing directly with insurance and that we wouldn't need to worry about anything. Therefore no costs, no options, no explanations of services were ever given to us. When the bill came back higher than insurance would cover they assured us that Joyce was the best in the business and would get it taken care of for us. the gap ended up being $3000 out of our pocket and as far as I can tell, no genuine effort was made to come to an agreement because we would have to pay it anyway. They were not actually working for us. In addition, the whole process was frustrating because appointments were made with us, where we canceled plans and they never showed or called. They removed equipment before it was dry and then covered themselves by putting it back in. At the end of the day our house is dry as is our bank account. I DO NOT RECOMMEND!"

"They came. They saw. They conquered. Plus it was affordable for the job. No excuses, nothing, but hard work. Once they arrived, they let us know they were there.
