Got a quote for painting my hallway and stairs. When giving the quote the painter counted the number of doors to gloss to make the estimate. On arrival yesterday I asked him to gloss a skirting in my kitchen and asked how much extra it would be. We agreed £10 more. Late in the afternoon he said he couldn't do the doors as they have a special finish and it would waste them, something about them being UPVC doors. I asked what to do about the marks on them he said he would patch them up. Anyway, I asked how much it would be now he wasn't going to do the doors fully (11 of them) and he said let's just leave it as it is as he will patch them up. AIBU to think he is being unreasonable? I would have expected it to be cheaper? How would you approach this?
