Just wondering if anyone has ever had this done, how well it worked, and a vague idea of how much it might cost to do.
We're in a 3 bed Victorian semi that was made into one house at some point then converted back into two houses but with very thin walls (particularly where doors used to be).
The house next door is rented out and we could hear the conversations (and fights) of our last lot of neighbours (although bizarely next to nothing from the previous few lots).
