Mould help

[meltedgalaxy]

Hi,

We live in a pre-war terraced house, windows are about 15 years old. Had them checked, no problems.

We get so much condensation, I manage this by opening windows daily and have managed to keep on top of it.

However, DH is somewhat of a hoarder and stuffed that much stuff in our back room I've been unable to access it (pregnant and couldn't move things myself)

After a major kick up the arse he's had a full clear out.

The back bedroom will be the baby's room and I found a considerable amount of mould, all black mould on the walls.

DH used cillit bang mould spray, scrubbed the walls clear. We've kept the window open and the room is empty except for a single bed (which needs to go too as mattress has mould on)

Am I doing enough to keep it away? Should I be doing something else, or more?

I need to paint over it. But I don't want to do anything until I know what's right to do? As the new baby will sleep in there I need it to be mould free.

We have this in a north facing corner room. It's just a case of keeping on top of it. A decent dehumidifier run a few hours a day will help, as long as opening windows and wiping away condensation regularly. Try not to have stuff right against the walls if you can, to let the air flow

Clean with anti mould spray as you have done
Windows open for circulation
Heat on if you have radiator in room to dry it out
Dehumidifier
Once painting, you can put put on a stain block for mould (although apparently this smells) or use an oil-based white primer according to my decorator, which smells less

If you have a high-tech fan or temperature control system it can tell you what your humidity levels are in your home, I think 40-60% is the recommended % window

It's possible there is excess moisture in your home overall because of lack of circulation (which you are fixing) or it could be an issue elsewhere... e.g. is moisture in all your bathrooms being sucked out via an extractor fan / window, same in your kitchen. If not then this might be contributing to high humidity in your home, which gives more opportunity for condensation to build up, and hence mould... or do you have a lot of laundry drying that releases moisture into the air? Anyway, some other things to think about!
