Hi all

Got damp coming through the wall where the vent is, because someone has filled it from outside with foam filler that has now hardened. Does anyone know how to get this out? Inside the vent goes up so it’s hard to get to, if this makes sense.

Attached is a photo of the vent and the damp underneath.

Thanks

Hi laxalt
Clear as much as you can from inside then try poking in the holes in the air brick on the outside. If that doesn’t work knock out the air brick, clear the foam and mortar on a new one.
