I live in a terraced house which is around 100 years old. Every morning the bedroom window is covered in condensation and there are also damp patches on the outside wall (at the bottom) and behind the wardrobe. There is also black mould in the top corner of the room - also on the outside wall. This has been a problem for sometime which gets worse in cold weather. Ventilation seems to help as does the dehumidifer which I use regulary. Is there anything else I can do? I'm worried that it maybe causing long term damage.
Also - damp patches are also starting to occur downstairs on one of the walls behind the furniture (again towards the bottom near the skirting board) and condenstaion seems to be increasing on the downstairs windows (its open plan downstairs so effectively all 1 room)
Is this the same problem (i.e. condensation) as upstairs or is it rising damp? The difference with downstairs is that it creates an orange/ brown mark which looks a bit like rust. There isn't that much of this but it seems to be increasing - it seems to occur around the frame of the front door which we don't use. The kitchen cupboards also have that misty smell which drives my Mrs mad!
I've lived here for 2 and a half years but I've checked what the previous owners left and the damp proof work was done in 1985 so maybe this is the problem? - although it says the damp courses are guaranteed for 30 years.
Any advice would be much appreciated.
Dave
