Thanks John, we will give that a try.
Once this is done would you recommend painting over the damp mark again with undercoat or will we need to get new plaster?
Thanks
Good questions as I didn't mention this,
there isn't a chimney pot anymore, when the roof was re-done we got them to take it down and slate over the area.
Hi,
I'd really like some advice please.
We have a top bedroom that has a damp patch on the gable wall. When the weather has been dry for a while, it patch is lighter and seems less obvious. The wall is papered.
The patch takes the shape of the chimney and is in the right place for it...
