Would love to hear your examples, for reasons of schadenfreude as much as anything.
Recently had professional interior paint job done, to save time as much as anything. Painter came recommended and was at higher end of quotes we got, so had high hopes.
We were unhappy with finished job but had already paid in full before paint had dried and finish issues became apparent (not sure how you get round the paying before paint has dried issue btw?!) Painter did come back, eventually, a few times, to fix the 'bigger' issues we weren't happy with, but there are still quite a few niggling issues but I don't have the energy to raise them with him too. (While I'm not a walkover by any means, I hate confrontation, especially with tradespeople and anyone who has to come back into the house etc.)
Basically, it's not the perfect finish I expected and I honestly think that if I had the time spare (and I don't!) I could do as good as job, if not better, myself, and saved £1200 to boot!
Maybe I'm expecting too much? DH thinks I'm being too perfectionist but I did expect more. I've felt the same way about a number of other small house jobs we've had done too. Tell me I'm not alone??!
