Cavity wall insulation removal

[meropenem]

Hi, I've just had a building survey completed on a 2 storey 3 bed semi detached house. It picked up some minor damp issues and suggests that the cavity wall insulation should be removed.

After having done some reading on the issue, it appears that wall insulation causes a lot of problems in the old houses.

Does anyone have experience of doing this and the rough costs involved? Is this something I could negotiate a lower price on the house?

A word of caution, I was discussing this issue with a proper damp surveyor a couple of weeks ago. The insulation is often small beads which become compacted. Some companies are using equipment with flails to break up. Where wall ties have become corroded from the damp this can snap them.

Wall cavity insulation is an utter scandal.
