i have mould spots in everyroom upstairs, mainly on the ceiling of the outer walls with windows, but nothing around the window itself. i also have water beads every morning upto approx 2 foot from the outer walls, i have vents in windows and keep heating at a low throughout the night

if it isnt the windows then it may be worthwhile to get the roof looked at for a leak, im no expert but i hope it helps cheers.
