P.S. Thanks Silver, that's some good constructive advice.

I am taking heed, it's just VERY daunting. As I walk round the Bungalow, I see lots of cosmetically scary things. Even if we sort the biggies, there are still quite a few little things too.

The bungalow was built in the early 1930's using some odd kind of mortar, which is really crumbly and some parts need fairly serious re-pointing.
