The survey on our house showed damp to the chminey breasts and damp to a partition wall. We knew the problems and went ahead with the purchase. I've sorted out the damp in the chimney as it was not ventialted properly and this seems to be on the mend. we thought we better get the professionals in so we had someone in last night.
He was actually baffled and is getting his boss to come and have a look. in several walls he was getting high readings right next to low readings and he also spotted some damp in places we had never even noticed and I'm sure were not there when we moved in.
i have a theory but its probably rubbish. its an end of terrace at the bottom of a hill, its got stone floors in the hall and back room and suspneded timber in the front room - the most damp is in the partition wall between these two areas. could it be possible that a lot of this is condensation casued by the recent hot weather combined with the contact with the stone floors?? another theory is that we are decorating the room above and have been using a steamer and a great deal of water.
any thoughts as to how these "patchy" readings could occur other than the damp course failing?
