Hi everyone,

We would appreciate some advice on the below issue:

There are cracks apearing on some if the walls through out an area of
the house (internal) and I need to asatain if there is a serious
problem. When I recently had a small room upstairs re plastered I noticed
there was some decay upstairs between the iner suporting wall and a
small gap between the iner and outer wall.

Not very clear.

do you mean there is a gap where an internal wall meets an external wall? -
if this is the case then there's a serious issue here. The external wall is
moving away from the internal walls - the internal walls will stay where
they are when the external walls start to fall over....also it's unlikely to
be wall tie failure as mentioned elsewhere - when wall ties fail, the
external leaf of brickwork parts company with the internal leaf, that is,
the cavity gets wider, the internal leaf of the outside wall doesn't
generally move away from the internal walls.

There are also cracks on both the ground and 1st floor internal
walls. The cracks in the house have been increasing over the last
month both in size and areas.
Please advise. If you can help!

Not really expecting a reply to this post as those who use that website to
post here rarely, if ever, reply to replies, but on the off chance you do
venture back here and see this, get a structural surveyor in pronto as
something dangerous appears to be going on, and if it's been noticable
within the short space of a month, I personally would not sleep in that
house one more night, and this isn't some amateur panicking, I've been in
the building industry since leaving school in 1979. Houses don't fall down
for no reason - someone has made a serious structural mistake at some point
in the past year or two and these are the results.
