Dampness on wall and ceilling

Rockfish

Was visiting an elderly Uncle over the weekend and noticed he has a bit of problem with dampness in his house. As he reckons its too cold (he has a point) he never opens his kitchen window when cooking or bathroom window when using shower and these are the rooms with the problems. Took a couple of photos and would appreciate any advice how to clean up now and what preventative measures to take in future, would extractor fans do the job or a humidifier?

The issue in the kitchen is confined to one wall and is mainly near the corners.

Anyone care to recommend a suitable cleaning product?

I don't see damp. The mould is from condensation. This can be caused by no insulation, stale air, no or not enough ventilation.

Its simple enough to clean. Spray bleach, leave half hour and wipe away. May take a few goes but you'll see it working after first try. You can buy special mould killer and anti fungal spray if you want.

Milton fluid will also kill it.

Woodies, B&Q, Homestore, etc; approx €7. Great stuff. Ventilate room when applying as it's a bleach content. Spray affected areas and leave for 5 minutes to do its work. Then simply wipe away residue with clean damp cloth.

may help with understanding the ceiling problem, without any external, internal corners context impossible to advise re what the issue is with the wall.
These bleaches are all fine and dandy,( ignoring the threat of respiratory damage from the chlorine mist when you spray,) but you need fans, in the bathroom maybe a humidity controlled one as he may not use it.

Get some sugar soap to clean it, then give it a coat of unibond or Auqaseal, then paint it. Only thing is the problem will return without proper ventilation.

expensive bottle of bleach active ingredients 2% sodium hydroxide and 5% hypochlorite which is exactly the same as a bottle of aldi /lidl bleach which costs 1 euro

The Astonish range of cleaning products has a mound and mildew cleaner that
Is very good and reasonable to buy. Mr Price stocks it.
