Hi everyone! My uncle's neighbours have recently had a loft conversion. Uncle was surprised after taking his copious amounts of "before" pictures that there was actually one missing brick where he could actually see through the gap into next door! The house was built by a very reputable and well known developer back in the seventies, and indeed, the attic party wall starts out okay at the bottom, but it looks like a badly knitted scarfe where someone has dropped some stitches and it looks a bit rough to say the least. The brickwork is pretty jagged in places and quite "messy." Although the small gap has been closed up by next door's loft extension, uncle would feel a bit safer if he could get something which would insulate against both noise and fire and give him peace of mind. Uncle, also intends selling in the next couple of years anyway, so thinks that sorting this issue would be a good idea. Any advice would be appreciated! Thank you.
