Damp wall

[nickk]

Usual problem,wife trying to sell her old house 1860 brick farm cottage,semi. Next door been empty a few years,hers been empty since February.
Internal wall is damp 3/4 the way up,no mould,paint is powdery,regular emulsion.
When she purcha it 23 years ago ,this area was damp a foot up the wall,it remained like this until tenants moved out in February,so maybe as a result of unhabitation during this short period?
Shes just had a buyer pull out due to this but as its 200miles away it’s not easy to just nip down and open windows put some heat on ,then return a few weeks later to evaluate and make an informed decision .
Any experienced renovators here had this problem and dealt with it effectively?
Thanks.

internal wall inbetween your house and next doors ?

or your front room and back room

is there any chance of a water pipe above where the problem is

is it on the wall where there is a chimney ?

I was in this situation a few years ago, my solution was to panel the wall with an inch air space between the wall and the panel. It won’t really solve the problem but no survey will pick it up.

Between front room and rear room,no chimney or pipe above.

Damp on a wall?

I'd be interested in the forum's collective thoughts on the attached photo. :thumbup: Report of 'damp' by a tenant on a 1890's terrace. This is on an adjoining wall.

Internal wall could still have capillary action taking the water up from the soil below.

You've got the whole "there's no such thing as rising damp" crew who have never seen blotting paper, but that's another thing.

My approach would be lime plaster and a breathable paint once I'd made sure nothing else was causing it.
