Hi, can anyone help us with our damp problem???
We moved into our 1950's bungalow about eight months ago. The full structural survey showed no significant damp problems. It just flagged up a corner of our bedroom which the surveyor put down to a external step being too high relative to the damp proof course.
Two months ago I noticed small black spots of mould growing in the lower parts of the two external walls of our bedroom (north and east facing). The problem is particularly bad in the bay window. The same problem, although to a lesser extent is present in the bay window of the living room (east facing).
The childrens' bedrooms are located in the extension which was built in the 1980's. The condensation in these rooms is confined to the lower part of the window. The walls are completely dry.
The extension has a concrete floor, whilst the original part of the building has a wooden floor. I have checked the external walls and can see no obvious cracks or problems.
I am assuming it is likely to be condensation due to the locations of the problems. Now the weather is cold, the skirting boards are literally running with water. The mould is also quick to reappear (we periodically remove it with a mildew remover).
We have tried to limit the moisture in the air - washing dried outside where possible, extractor fans in bathroom and kitchen, window left open for an hour or two during the day. The furniture has been moved away from the affected walls. Is spite of all these the walls and skirting still run with water.
What can we try next? Any suggestions will be gratefully received.
Happy New Year.
