Question Author
I made a list right from the start (over a year ago), after months of 'fixes' that didn't work, and a lot of "mmm, I don't know what caused that/I don't know what to do about that" I gave him a week to get things sorted, which of course, they never were. A price was agreed at the start, but I did add a few other things as we went along. (Before I knew how rubbish they were).
Something I forgot to add to my original question - Did they have the right to take the old floor tiles which they removed to the reclamation yard without my knowledge? I assumed they were going in the skip, but it has now been suggested otherwise by one of their sub-contractors.
Thanks.
