Had nieghbours with no respect drilling party wall at nite etc so when i went on hols for 2weeks i bought an old cooker extractor & fixed it to paty wall secure but loose so it rattled like fcuk & put it on timer for whole time i was away. They been more mindfull since & always let me know in advance of any diy etc & i do the same. We’ll never be mates but respect/curtesy is paramount. Hope you get it sorted bud. Atb
