Just buying a house at the moment that has had years of neglect. One
of the problems is a broken guttering pipe (in fact it is just loose,
but has been loose for about 15 years). This has led to water getting
through the brickwork on both levels and causing really severe
penetrating damp. One wall (upstairs) has been replastered in the last
few years and the plaster is totally gone in the corner. The
downstairs is not as bad but could still do with replastering.

The mortgage valuer has mentioned that the plaster needs to be removed
and the penetrating damp treated "by a company that can offer
guarantees for such work". What kind of treatment can you do to this?
The cure is simple, stop the water pssing all over the wall, let it
all dry out, and re-plaster. No special work needed.


Is it a matter of knocking off the plaster to the brick wall,
repointing outside and waiting a sufficient lenght of time for it to
dry out before replastering?
That's about it.


Or can we just repoint, knock off and replaster with waterproofer added
to the plaster mix?
Is it an old house (how old?) or new?

Victorian terrace (liverpool). Needs fair amount of work doing to it
(lateral restraints, full gable, outrigger and rear elevation repoint,
DG, window lintel to replace, through lounge lintel to replace, most of
downstairs to replaster.
Apart from that, quite tidy :

Just do it. With the guttering fixed, the damp will subside. Don't even
think about replastering until its all dried out.

Would placing a dehumidifier in the room help with the drying out from
the inside?
