They came to my house to fix a drain that was backing up 3rd plumber we had there. First one to say we should get a camera and see what's going on. They used the camera told me there was a break in the line. We need to replace the pipe. Said they would get back to me in a few days with price. I called 4 days later said they would have someone call me. They never did. So I called another plumber. Thank goodness I did! because there was no break in the line!!! just a bad clog that was very difficult to. My pipes are working fine now. Thanks to Precision Plumbing. There's lots of good reviews on here about Dms. be careful as they may have posted those good reviews them self. Dms did get $550 out of me for a false diagnosis.
