I don't know if this is the correct forum for this but here goes. I have recently moved into a four year old house and have noticed that whenever anybody moves around upstairs there is a lot of noise from the floor, it sounds like the ceiling is cracking tho in reality it isn't. Is this because the builders have used sheets of chipboard for the floor as opposed to floorboards, or is it incorrectly installed. The builder was Harron homes (say no more) so it should all be built to the latest regulations eg joist size etc. Any advice? Also the stairs are very creaky, again any advice?
Thanks in advance.
