My house smells of damp!!
We moved in about 18months ago to a cold damp detached bungalow which had been empty for 3 months. It smelt. On putting the heating back on, condensation started running down windows by the bowl full. The old owner had left us a de-humidifier. (Wish I’d seen that on the viewing) we obviously started using it.
We've since changed most of the carpets etc and thought we'd cured the smell. How wrong I was.
We did find that the extraction in the en-suite was blocked so changed it. Again this helped reduce the amount of condensation on the bedroom window in the mornings.
The de- humidifier now spends most of it time in the back bedroom were it currently take out 3 litres of water every 24 hrs!! give or take a few hrs weather dependant. I occasionally move it round the house and it takes out about a little less but it is working hard.
We do have a few black spots on walls in the house.
We don't have any obvious signs of damp on the walls and our loft is well ventilated
If any one has any ideas to help us understand the problem would be great.
