Oh lordy, there must be a few debates going on now, after all the recent gales.
We have this problem, to a degree at the moment, with our neighbouring house. Unfortunately it is rented out, and is awaiting new tenants. The fence between us is rotten, and near the house, only the ivy is keeping it upright. At the bottom of the garden, the fence is falling over.
Luckily we still have the old, original wire fence between us on that side, so the damaged fence is not ours. But it looks so unsightly. I do not understand how a tenant would want to pay rent for such a mess, but I doubt whether the owner will want to pay out for a replacement.
The fence at the other side of his garden, is in the same state.
