Gary - thanks for the pictures and info - the work is appaling and is miles away from what is required in terms of prep and certainly fixing. This guy has absolutley misrepresented himself if he calls himself a tiler, signwritten van or no. What's interesting is where / how the work came to him through - since the client was choosing a Smallbones kitchen, as you say several thousands worth - you would expect greater scrutiny. Even so why did he turn in SUCH poor work. Is that his standard!? There must be many disatisfied customers of his, and any contractor still using him must be mad.
The point being that, as is not unusual, the tiling is often seen as a minor and less important part in the project by someone placing the work - yes the tiles themseves will be considered and ooohhd and aaahd over, but the lack of knowledge regarding proper installation is completely lacking.
I've just done a rip out for some people where the work was equally as bad, and the bloke was a recommedation; the tiling didnt even look that good, let alone what I found beneath (not) holding it on.
The client should go for him, he charged for proper work, and didn't even start to deliver it. To re-do all this the whole works on top would need to come out and start over.
Do we think he might use this forum and see the work!! ??
