This was not just for repointing, but it was on sound ground and access was easy. More recent estimates for simple repointing work on chimneys would suggest 10 grand plus without heavy plant or work on the foundations. Any professional Civil Engineer like to comment on cost.

No it is still the foundations that are the problem but this could be an additional problem which could result in further reduction of the chimneys stability.

I did not think it was legal to do this to Scheduled Monuments in Wales. You have to get permission from the Secretary of State for Wales (via CADW) before you can do any work on a Scheduled Monument. Vandals are obvious exempt from this requirement.
