This could be true but then who's job was it to prep the floor. Even if adjusting the joists so level enough to reboard onto was not in the quotation then it should have been flagged up as a problem prior to continuing. I question the structure of the floor here as how many profesionals would now reboard a floor (presumably t&g) and then overlay with ply? (reboard with ply(or other) then tile backer board would be my option).
Most of us do that to some extent but we shouldn't according to BS5385 as the substrate should be prepared correctly (i.e. flat).
I am not really seeing much of a problem with the tiling in the pics. Take the first one yes there is a bit of a gap under the skirt which could be due to slight rise in the corner tile or twisted skirting. Either way the skirting could have been scribed to the floor and/or a white ( rather than clear) sealant could be used. The same I think is true for the other photos. Taking a picture with a level on the tiles that then shows unevenness or lippage may be more meaningful.
The pic with two skirts meeting at a corner (different heights) is not good but again just needs scribing to the floor so they meet.
It was his job to prepare the floor. The pictures don't really show just how uneven the tiles are. The reality is I think quite simple, he is not a professional tiler and the mistake made are very basic, that is, the adhesive was applied unevenly and/or the pressure he applied in setting the tiles was uneven, hence lips all over the place.
Here a few picks taken with a straight edge across, it doesn't really matter where on the floor the edge is placed, it pretty much shows the same unevenness.
Bottom line is that I think he's done a cr@p job and that his excuse are pathetic. I've done tiling myself (very much an amateur) and I have to say I would have done a better job.
Do you think it was a good job?
