Last year we had our driveway redone which included putting small white stones along the fenced border to our neighbour. We are on a hill and the rain water has led to running off some of the white from the stone on to our neighbour’s driveway which is old red brick and it is now stained in parts.
He claims he has tried to remove the white staining but failed.
We have the same stones in our back garden and there is no staining so it must be due to living on a hill and the water flowing downwards
UABU - we should sort
UANBU - it’s their responsibility
