We spend quite a large proportion of the weekend (and Stevie did a lot more than I did) replacing the old insulation with new stuff.
It is a truly hideous job as the house was quite a hit with the local wildlife in the 9 months or so that it was empty. (rentokil have since been out and have confirmed that we no longer have mice or rats. We seem even to have frightened the spiders away).
So we donned masks an protective clothing as apparently you can get viles disease or something.
