Hi
I’ve discovered our skirting board and plaster is damp, smells musty and paint is starting to peal off.
we know previous owners experienced water damage in same location due to a leak from the adjoining Town house 3+ years ago. However this is definitely new moisture.
however, due to the location it’s also possible to be rising damp from my research .
who would you call first? A plumber or a damp specialist ?
