Covering a broken air brick If an air brick gets broken, don't block it up; you will prevent ventilation, which could lead to rot in the floor. To make sure that rodents or birds don't creep in, cover the damaged area with chicken wire or plastic netting, until the brick can be replaced. Dampen the wall opening and the new air brick, then 'butter' them both with mortar and insert the new brick in the hole. Tap it in place with the handle end of the club hammer (never with metal which could break it). Wipe away all surplus mortar, and point the joint around the air brick (see Brickwork). Use either the trowel or a short piece of copper pipe bent to a curve - depending on the shape of the adjacent pointing. YOU WILL NEED Club hammer, cold chisel, heavy-duty gloves, safety spectacles, dustpan and stiff brush, small trowel, new air brick, small bag of dry mortar mix, piece of board for mixing. Possibly: short piece of bent 15 mm copper pipe.
