+1 to all of that.
I think the problem comes when you're starting out cold. You move somewhere new, so you don't know anyone. You need your aerial fixing (for example), but none of the neighbours have needed work on theirs. If you find someone and they don't do a terrible job you'll next need the aerial fixing in about
20 years, so the relationship isn't worth investing in.At that point you can ask around people you don't know for options. But a lot of them can be gamed by bad people ('trader' sites, Facebook groups, etc). So it then becomes a task of trying to out-game the gamers (do those reviews look genuine, was the Facebook recommendation written by the trader's brother?). Which is all rather tiresome and not a skill everyone is good at.
