The house damp course was breached with paving but this was rectified about four months ago. A few days ago I found more mould on the wall. Is this because it takes time to dry out and spores are still present or something else?

Allow roughly one month for every 25mm of wall thickness. So a 200mm thick wall will take 8 months to dry - Cavity walls will dry out quicker. Last couple of months have been cold and damp will will slow down the drying process. And a cold damp wall will also attract condensation which isn't going to help.

Thank you. That is reassuring
