Thanks Matty!
Hey another problem here! I have been lifting up the old cupped warped floorboards and noticed at the top left of the lounge has a black patch. It looks like a damp patch but the skirting above it had no rot or fungas strands coming from it - could this area be where the previous owner spilt water/overflowed a xmas tree for example? I also noticed some yellowy powdery spores of some kind under some of the old solid wood floorboards, do I have a damp problem?
I am getting a meter tomorrow to check but best to ask you experts!
cheers
