We hired Gary to remodel the bathroom and install a custom shower. After a year we noticed tile cracking and popping off the shower floor. (because of his professionalism w/another bathroom we did not contact him for this, both bathrooms were "completed" before any issues were apparent.) While trying to investigate the problem, I went behind the shower wall (the wall is open in the utility room.) and stuck my hand between the membrane and sheetrock, it was very wet. In order to prevent mildew we demolished the very bottom of the shower wall. This is what we found. Gary installed the membrane for the custom pan, incorrectly, he used the wrong product to create the pan, he installed a drain for a fiberglass pan, not a custom pan. The drain is not level. He installed the sheetrock to the floor of the pan, which is incorrect. So this is what was happening, the wrong drain didn't allow any extra water that didn't go down the drain to seep out. The water backed up in the pan and eventually was being soaked up the drywall. I have photos and I have tried to contact Gary w/ no response. I now have to file a lawsuit in superior court to attach his bond per WA state regulation. I asked for a bathroom and got a petri dish.
