Hi All
As background, my house is a victorian mid-terrace and I've lived in it for just over a year.
As I was leaving the house this morning I noticed few damp patches in the hallway, on the interior wall which separates the hallway from the living room just above the skirting. I can't see how the damp could be caused by a leak, since there are no radiators against this particular wall.
When I bought the house I'm sure it said that damp proofing was put in some time in the 1980's. However, isn't that usually done for just the exterior/adjoining walls and not interior? Also, for how long does damp proofing actually last once it's been installed? Is it common for interior walls to need damp proofing?
Any help/thoughts would be much appreciated.
Thanks
