Bear with me on this please.
I have a victorian 1910 mid terrace and last night stripped the wallpaper off in the front room. Behind I found what look like two damp patches. The front room has a floating floor of which I can get under and after a quick inspection it looks like the DPC has gone ie you can get hold of a piece and it will snap off.
Does anyone know how I can resolve this? i was thinking that to replace the DPC on such an old house would be a nightmare and wondered if painting the exposed wall under the floor with somthing like linseed oil would be the best bet. Would coating the underfloor section of the wall with insulation be of any help?
Cheers in advance folks.
