Haha, if I could work out the offending apartment I'd certainly be letting them know.
Would pay someone to walk past at random hours and call their apartment.
A couple of weeks ago I took the plasterboard off a party wall in one of our bedrooms, only to find no sound proofing material in the cavity at all.
The wall was constructed as follows: One layer of 16mm plasterboard (my bedroom wall), then the cavity, then another layer of 16mm plasterboard (their kitchen wall).
I put Earthwool soundshield batts in the cavity and sealed it all back up.
I haven't heard anything from next door since.
I'm going to glue a layer of 6mm cork over that.
I guess I'm "lucky" that I'm an owner occupier and can do work like that.
But I have no idea on how to deal with the washing machine, it's coming from somewhere else but I couldn't identify the apartment (could be from anywhere).
Blurgh, another apartment had their washing machine going on spin cycle at 3:40am. Made our apartment hum and rattle.
Then furball decided she wanted food at 6:40am.
I tried to pop into Troika Bar yesterday, but it was closed. I've been away for the last month and I'm hoping that it's closed just for the Xmas break, but through the window I noticed that all the silver mylar/foil was torn down.
