My 85 ear-o mother in law lives in a bungalow at Bosvenna View Bodmin, PL31 1AZ. In the living room, there is a defective floorboard under the carpet which gives way whenever it is trodden on. It's a potential trip hazard for her and I would like to get it repaired asap. I have pulled back the carpet and examined the board concerned, but can't tell why it is sagging, so cannot say if this is a minor or major job.
