1. Open windows, heat and keep moisture levels low
Damp and mould occurs due to too much moisture in the air in poorly heated and ventilated rooms. Watch this video to show you how to reduce the occurance of damp and mould.
2. Flat above may have leak
If your ceiling has a damp patch then your neighbour above has a leak. You need to make contact with your neighbour to get it fixed. We are unable to fix the damp patch until the leak has been fixed.
