Hello this is my first post and sorry if I've started a new post unnecessarily but I don't know what else to do. I've had my end-of-terrace house for 4 years now and was originally 2 house knocked into 2 with openings upstairs and downstairs. There was a little bit of possible condensation in the bedroom but since the openings have been blocked up again we've had wallpaper peeling off and black mould on the walls, especially under the windows and in the corners. It's an early 1900s terrace with solid walls and a basement with that can be accessed from the back door as 2 of the walls are against earth. It had a DPC about 15 years ago. I've not been able to decorate properly yet because it comes of after just a few months. I know condensation is a real problem with solid walls but I'm not sure how to remedy this? I've had a Drimaster put into the loft but it doesn't alleviate it all. I have no air bricks or extractors fans of any kind and my wife dries the clothes in a condensing tumble drier or on the radiators and we also have a coal fire. I'm wondering what I can do to help. I've got some ideas but I'm not sure what's best to do and if indeed it is just condensation? Any ideas would be greatly acknowledged, thank you.
Thank you for your response, I'm going to have some extractor fans fitted. My wife has started drying the clothes in a condensing dryer but would will that be contributing too much into the house. The washing machine and dryer are both the basement. We only have a 2-bedroom house so could the bathroom be causing the wallpaper to fall off and the mould in both bedrooms because it doesn't always get closed and the window left open for long enough. Thank you.
Suggest you fit extractors operating by humidity stats.
You could also try using a de-humidifier with reheat to purge the high moisture levels.
The condensing dryer should have no effect on moisture unless the dryer is faulty.
