    Air vent to tackle condensation

    Moved in 2 years ago, and had condensation issues in winter, in the rooms with external walls (rooms which have the the four corners of the house).

    Wet Rafters

    Hi all, I'm looking for some opinions on the cause of some wet rafters in the attic. The rafters to the rear (north facing) elevation are all wet on top and down the sides. The rafters on the front (south facing) elevation look to be okay. I'm trying to work out if the likely cause is a roof...

    I have a brick garden store, approx 4’ x 10’ that is very damp; I had the roof replaced a while ago, so it’s penetrating rather than leaking. There is currently no ventilation. I’m thinking I probably need to install air bricks at either end to get a through flow of air, but have read...

    I have a soil stack in my attic that I discovered is open. I fitted a Durgo AAV but this caused gases to build up and leak out from the bath p trap. I took the Durgo off and the smell stopped. So I'm thinking I need to vent the soil stack externally. My roof is asymmetrical, it rises to the top...
