While in the loft I lifted some of the insulation to find that virtually
all
the 'key' bits of plaster that squish through the lath were detached and
just littering the surface. However the ceilings seem to be staying put. I
can't think what's holding them up! Do I have a serious problem please?
The
house is 1930's.
