Had them do a basement reno in which I had already jack-hammered the concrete for the plumbing. They were given the run of the basement and had their helper set up the lines, which required a bit of pick-axe work. In my opinion, they should have owed an electric jack-hammer to make it easier for the guy cause it appeared to have cut corners with his NEW location for the toilet. It ended up that where they set up the toilet was 8 inches from where I had planned (they were given a VISIO computer layout for the bathroom. The final location BARELY allowed for a 24 inch vanity. The rough in for the shower and bath was well done, BUT they didn't leave the taps and trim for the plumbing and now I have to figure out what taps go there. Luckily I am not in a big rush to complete the job and can check out better contractors to finish the job. They did good work but must be watched for details before they get to the point of no return.
