Cavity wall ties.

    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.

    Gable End:

    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.

    Rear Ties:

    Do you have any paperwork or certificates confirming this - if so then all
    should be ok there.

    Front Wall:

    Unless it is a 'solid' wall (unlikely in this case) then there will be wall
    ties present and may well need 'sorting out'

    Thanks Brian. The bulge was just the outside skin which the builder took down
    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.

    Thanks again.
