After nearly 4 years of dispute with my neighbour we are finally getting near to resolving the laminate flooring issue in their flat (I live directly below them) - they can't sell which is why the sudden change of heart.
We have agreed to split the cost of insulating the floor of their flat (I just want to ensure it is done properly) and after spending many sleepless nights listening to them banging around, I think I have identified 3 issues which need to be resolved:
1. Laminate flooring needs to be taken up and a proper acoustic underlay needs to be put down
2. Squeaking floorboards need to be repaired (the neighbour said he has already screwed them down but the timber building moves)
3. There is a 6 inch void between their floor and my ceiling which needs to be filled.
Can anyone on the forum please advise on:
1. Which is the best acoustic underlay to use for impact noise in converstion flats;
2. What else apart from screwing down the floorboards can be done to repair them, particularly if the building moves; and
3. Does using a mineral wool in the void reduce noise?
Also, can anyone recommend a specialist company to do the above - I live in London.
