My house is so damp! The front of the property isn't too bad and I only get damp and mold covering the wall underneath the bay window. The back of the property (outside walls) however is really bad, especially upstairs where I have to re-decorate every year or two. To give you an idea of how bad it is, my box room was re-decorated in November and has had a new wardrobe in it. I looked at the back of the wardrobe yesterday and it was completely covered in mold. The walls used to feel so wet that I now leave the window slightly open at all times which makes the walls feel dry but the mold still comes. There is also a de-humidifier in there that I use from time to time (not with the window open when operating obviously). This is definitely the worst room however my middle bedroom gets lots of mold around the window, walls and celing around there too, and my kitchen walls feel wet to touch. I once had somebody round to look at it and they said to open the windows more. To give you some extra information, I bought my house 10 years ago, there was no central heating in at that point. This was fitted about a year later so the house is nice and warm. We had a neighbourhood renewal scheme which replaced the guttering about 7 years ago. The roof was checked over last year and a couple of slipped tiles were replaced. So what can I do about this problem? Is it possible to get rid of mold?
