Another where's the damp coming from thread.
Background - 1930s semi purchased a couple of months ago. One small patch of damp on a back wall near a French window picked up on the survey thought to be due to failed DPC. Another couple of spots on the plastered over chimney breast in the loft thought due to leaking flashing.
All well and good, we are awaiting DPC treatment to rear wall of house near the damp spot (dubious benefit I know) and repair of flashing/repointing of chimney stack.
We are not living there yet as it is being refurbished so have had heating off most of the time. We have been stripping wallpaper, removing skirting and removing some damaged plaster.
This weekend we noticed a new patch of damp in the kitchen which is an extension built onto the side of the house. It is about 1/3 way up the wall above a radiator. Two new patches have appeared at the base of the same wall but about 4m away either side of an arch which leads to a small back porch. I assume the affected wall was previously the external wall of the house.
My question is, could the new patches just be due to condensation? It has been very damp weather and there has been a lot of condensation due to the wallpaper stripping.
We put the heating on and it is starting to dry out. Have had plumber in and no leaks. No obvious blocked downpipes or gutters and roof of extension looks OK.
Is it possible for condensation to cause this appearance and can we just ventilate and let it dry out or should we be looking for other sources of moisture?
