Hi.
I've been in this house for about a month. According to the previous owners, this little flat-roofed bungalow, built in 1961, recently developed a damp patch on the bedroom wall. They took out the concrete path alongside the house and put in airbricks in bedroom and sitting room a few inches above the floor. They blow a gale!
Before I bought the house, I had the damp checked and the report was that the house is dry. The one in the sitting room originally vented into the cavity, and has a sliding cover, which I've closed, which has helped. So far, there is no sign of damp in the corner.
The one in here (study-bedroom) doesn't. I put an old, large, plastic-covered blotter in front of it, moving it at bedtime, which helped, but with the very cold weather, have left it there most of the time, checking it for signs of dampness. It's been fine except on two occasions this week when there has been a wet patch on the blotter's room side while all around it is dry, but very cold.
My thinking is that this airbrick is causing more problems than it solves, in allowing very cold air to flood the warm room, leading to condensation.
I'm also going to have cavity wall insulation done, and it seems daft to do that and leave what amounts to constantly open windows in two rooms. I'm at home most of the time, so the heating is on all day. Another point to bear in mind is that I always have the bedroom window open at night.
Your advice would be very much appreciated.
