Thanks people, going to get the builders back in, I just want it sorted just wish I knew before we decorated but you live and learn
Found some pics of wall after first plaster and second is the wall when we knocked through.
Having the dpc cream done will that take a few weeks to form a barrier?
It was plasterboard and scim, the bit with the darker patches was the old outside wall,
That bit of the wall was under the old decking so am holing when they been back and removed the skirt and injected it all round it might if sorted it and will dry out?
since then it doesn’t feel as cold to...
Good job it looks like it might have to come off then,
I wouldn’t of papered if knew was a issue, but we left it a good 3 months from work being done til we did it, if it has to come off it has to come off I just wanted some advise on how to fix it if possible, thanks
He had some work done about 6 months ago but after new plaster in old part of house.
After getting in all wallpapered we have started to see signs of damp in what was the old external wall.
Got the builders back who removed the skirt and injected with dpc cream about 4 weeks ago, wall at bottom...
