Neighbors caravan against house

[Swann79]

I live in a detached bungalow. The boundary with our neighbours is the side wall of our house. They have a narrow driveway between our house and theirs. (Our path to our garden is the other side) Yesterday they realised it was just wide enough to park their caravan down. When I say just I mean just. The caravan is actually touching our house. I appreciate I wouldn’t have even known they had done this were it not for the fact we have a window looking out on their side path (luckily the window cill sticking out stopped the caravan from crossing our window!)
im worried about damp and damage to our house caused by this not to mention how rude it is!
our house was built in the 1930s and as far as I know has always had guttering and eaves and a window on this boundary.

Hi Swann79

Clean windows once a week and ask them to move van for access, They will soon find somewhere else to park it.
