Hi all,

My utility room gets very mouldy each winter. It is not part of the main house, it's a small extension, it has a couple of airbricks and it's unheated. I think the reason it's got such a bad problem with mould each year is that the floor is beneath the damp course of the house (you step down into the room).

I was wondering, do you think I might be able to solve the problem if I paint the concrete floor with with liquid damp course, plus the sides up to the damp course on the house itself?

Hi busy l,
If the extension is single brick then painting the floor and low level walls with liquid damp course will have little effect.
