How do you go about getting your visual for termite protection if you put a fence within 200mm of your garage wall?
if the gap is not accessible there is no termite boundary protection layed, however they will need to spray chemcical on the surface, and it needs to be done yearly.
In this scenario if they take the land you would need to ask permission to access and spray wouldn't you? I just remember something similar where our garage uses some of the boundary.
ninja spray ... nobody knows.
