Silicone filled air brick?
Hi, I have 2 air bricks on the front of my house, 1 is beneath the damp proof membrane and is ok, the other is around 5 bricks higher up and 2 to the side and has been filled in with silicone. Any advice appreciated on why this would've been done? Or should the vent be clear? I believe the cavity has been insulated.
I do believe that this would not affect the house as it was only two mini holes Blocked and I do believe that sky and virgin run the cables through Air Bricks sometimes and the silicon is just to hold the wire in place
