The Tub Guy

We were quoted $900 to re-glaze the master shower (tile) and the tile that is around the bathtub. It took them 4 hours to tape the bathroom because "the tape wouldn't stick" to the paint (marque one coat - satin finish). Finally they started spraying the tile and they come out and state that the paper had fallen off the wall so there was some over spray onto the painted wall above the shower. I said that's not ideal however we can just cut in with the left over paint when they're done. After this statement I decided to call off of work because I was worried about the job they were going to leave behind (I don't trust my husband lol). After they stated that they were finished, my husband and I go in to look and the "little over spray" on the wall, and it is all the way up to the ceiling - the whole area has to be repainted. There was also over spray on the wall next to the tub that needed to be repainted. Upon more detailed inspection there were some spots missed and some peeling and some not clear cut lines like I would have liked. Not bad work but definitely not great. He touched up what he could and i was OK with it. He then asked who was paying the bill and I stated I did not want to pay him the quoted $900 due to the fact we had to repaint all above the shower and next to the tub. He proceeds to ask "are you kidding?" and I told him I was not. He asked what I was purposing (obviously pissed), and I said $850 because we now have to go buy paint supplies and possibly more paint and spend a couple of hours fixing the bathroom. He told me he wasn't going to argue with me and I paid him the $850 and he stormed out of the house. Not only sub-par work but still expected the quoted price - what a joke. DO NOT RECOMMEND!
