It was my co-worker recommend Mr Rooter Plumbering for us. The toilet tank is just five years old and it started moving around. At first, we just ignore it as long as there has no water leaking. Then after couple days, it has been rocking harder and making funny noise, then we saw water leaking around the toilet tank. So we can Mr Rooter that day. We were very impressed how quickly they arrived to our house after couple hours that we had made that phone call. We thought it's going to be expensive and need to replace a new toilet. Less than two hour, everything was done and fixed. They said there has no crack, so they tightened each bolt and use some clear silicone to hold it all. I find Mr Rooter Plumbing honest and efficiency. I am glad I call them.
