We have 4dc and frankly our paintwork takes a battering. The hall and kitchen look shabby++ and were last done 8 years ago. I've got a decorator coming to do ds1 room this week and it's probably 6 years since it was painted. DH thinks it's excessive. Frankly if he lives alone it would be a pit. I think the whole house needs doing but he says waste of money.
How often do you re paint?
