The place I live in has all these issue which I need to fix at some point.
E.g.
Never cleaned the walls properly and all the paint is pealing off.
Sockets far too near a work surface, can't get a plug in
Same thing with the floor, cut the board off no on a joist and now it depresses when you walk on the carpet
I had a reputable TV company in North London, put in an aeriel and 4 connection points. F#ckin# idiot drilled the cables through my build in furniture with a SDS masonary bit and made a right mess of the hole.
Makes me angry just to think about.
Its why I got so interested into DIY.

Unfortunately there as so many chancers about who have no sense of pride in their work it gives the trade a bad name.
I have no problem a guy making a mistake and generally are quite forgiving about it, we all do it from time to time
