I'm hoping there's a specialist around here who can help me
with advice about our walls.

It's an old house built of brick with no cavity. The oldest
bit (C1720) has solid walls 3 bricks deep and mostly these
are OK.
A later addition (C1840) has walls only 2 bricks deep and
it's these walls that are causing us some grief.

The outside is painted, (the bricks are too soft for
sand-blasting) and the pointing is apparently intact but I'm
happy to be advised on this.
The wet summer has brought damp patches inside these 2 brick
deep walls.
I am loathe to try and seal the walls either outside or
inside, the seal only breaks down sooner or later.
I feel sure there must be a way that the insides were
prepared/treated that could cope with damp weather
conditions when these walls were originally built.

We do keep a trickle vent open in the windows and the rooms
do get heated when we have the central heating on.
It's not a permanent affliction, there's precious little
damp in normal weather conditions.

Any more information needed?

Classic stuff, this happens to lots of properties, and is usually
caused by incorrect maintenance. Part of the solution is removal of
the paint - certainly not by sandblasting thugh!
