The letter is from our neighbour
I agree with you, but the question is are we within our rights to repaint an unsightly wall on our boundary when the owner will not. They have repainted the remaining three walls of their house in recent years but not this wall because it is 'out of sight, out of mind'.
Just one final question, do you think the change of colour is significant?
It is a very pale light green as opposed to the original white, streaked with algae!!
