  • A random question- there's an airbrick in my back room that seems to mostly vent into the back of a skirting board. Perhaps the very lowest quarter of it is venting into the floor joists.

    Is there any reason it would be doing this, other than a bit of a bodge?

    It looks like it's been added to the property as part of a renovation at some point. There's a damp proof membrane (plastic) that seems to wrap under the brick.
    I can't work it out. The wall is a solid wall (10 inch) and the outside has been rendered- the airbrick is kind of tucked up behind the bottom of the render outside.
    Obviously it's causing cold draughts, doesn't feel like a good idea just to block it up though.
    Does anyone have experience of anything similar?
