Hiya, Trying to help our elderly grandparents. They have a bungalow that already had a conservatory built when they moved in. They are suffering with severe condensation, beads of water on the rafters which is causing mould / dampness. They have tried opening the windows, damp catchers and running two dehumidifiers but to no joy. Doesn't help their washing machine is in there. I was going to suggest either popping a couple of air bricks in or putting a simple extractor fan in. Whats the peoples general opinion / advice for this type of thing? Just concious they are not young bless them and they are struggling to wipe if down daily and want to try and help them out. Cheers Pete.
