Ok, Next door have had cavity wall insulated today.
Asked for access as their wall is our boundry. Fine, let workman in, they asked if I had a hose as it would be a bit dirty. Ours at back of garage, so when the work was finished they hosed down, and hosed car.
Went out for the afternoon, just got in and my entire drive (bricked) car , kids toys, etc covered, looks like a sand storm has hit our garden.
Don't want any arguing, what shall I do ?
