I paid them for unclogging the basement, but got poor service…
I paid them for unclogging the basement sink in my house. The agent assured me that the work was done properly, without even testing if the water would run down. Worse, the receipt stated the work offered no warranty. After I noticed the issue, I called them to report that the issue was still occurring. I asked them to come and assess my concern. They refused to do so. Instead, they asked me to pay for hydrojetting to resolve the issue. I called another plumbing company. When they came in, they could not believe it when I told them that Mr Rooter Plumbing had completed the same work earlier. They corrected the wrong service provided by Mr. Rooter and gave me a 12-month guarantee. I asked Mr. Rooter to reimburse me for the poor work provided, and they refused. Honestly, based on my personal experience, I would not recommend Mr. Rooter to anyone.
