My remodeling contractor used Mark Schneider Plumbing as a subcontractor to do the rough and finish plumbing for a remodeling project. Since project was on the second floor of my house, it was important that the plumbing work be done correctly so it didn't leak - since water follows the law of gravity and flows down when it leaks guess what happened?. Yup - total of 5 leaks during the project and had to remove the drywall in the ceiling below due to water damage. In one case they said that they soldered the shower valve joint but when we turned it on a massive amount of water came leaking through the ceiling below. Since the tile was already installed, the tile installer removed the tile and wall in that area and discovered that the shower valve was not even soldered - plumber said he even pressure tested this. Work done on the second floor copper and drains was so bad that I had it redone - big hunks of unmelted solder stuck to joints, drains pitched the wrong way. Also paid them to install a floor drain in my basement - he put it in the wrong place by over 2 feet and I had to hire another company to move it. and when they moved it we discovered that the joints were not glued correctly.
I dealt with 2 people at Schneider - the older owner who seemed knowledgable and his20+ year old kid. Unfortunately the older owner had his kid do the work. If the older owner had completed the work I'm sure it would have been much better but he had his kid do it - his kid is in the wrong profession.
