My Building Society is insisting that I have an expert report on the cavity wall
ties of my 1926 three-bed semi-detached house before they OK a mortgage. Can
anyone tell me how an 'expert' will carry out this examination and what the cost
is likely to be?
I had the gable-end rebuilt to correct a bulge in 1980 (presumably the ties
would have been renewed) and had remedial ties installed in the rear wall in
1990. The front wall with the double-bay windows was rendered in 1990, after
removing the pebble-dashing, I'm not sure whether there are ties in that wall.
Simply drill holes in the wall at strageic points and stick a boroscope in
to have a look around.
What was the reason for the 'bulge' and was it just the outside 'skin'?
This could possible have been caused through wall tie failure - and yes, the
ties should have been replaced at the time of the repair.
Do you have any paperwork or certificates confirming this - if so then all
should be ok there.
Unless it is a 'solid' wall (unlikely in this case) then there will be wall
ties present and may well need 'sorting out'
2/3rds of the way then rebuilt. I don't have any cert for the rear wall, apart
from the receipt for the payment which mentions the ties together with pointing.
In view of the front wall needing sorting perhaps a Wall Tie Report is not such
a bad idea and I have found a website which gives details of what is involved.
