We are in the middle of a bathroom remodel that was an unplanned, unbudgeted project. Had a bad water issue with the old shower that forced this on us. Something we would do in a few years just weren't quite ready now. Anyway, found a contractor we liked (still do) and got the job started. This morning he called me up and said he needed to come over and talk about the tile. When he got here we went to the bathroom where the tile guys were working and he told me that the type of tile we are using is a tumbled marble (I knew that) and that his bid was for regular tile. He and the tile guy went on to explain that this type of tile takes much more time and effort to install (I knew that to) and that he needed to charge me an additional $7 per square foot for the tile install. ($980) Obviously I wasn't to happy about that. I didn't say to much at the time as there were a few people around but I'm thinking that either 1) the type of material should be determined at time of bid to determine proper labor price or 2) if type of material wasn't chosen yet the bid should include a price for regular tile and a price for marble/granite...This being an unexpected project I'm not to happy about the extra cash. What do you think, should he meet me half way on this?
