A weep hole cover fits into an existing weep hole and expands for a friction fit in the weep hole. A vertical front plate includes a plurality of holes to permit seepage from the air gap behind a brick facade. A pair of vertical side plates extend back from the front plate, each at a right angle to the front plate. A pair of angled plates extend back from the side plates to contact the bricks on either side of the weep hole. The angled plates collapse for insertion of the cover into the weep hole, and then spring out again for friction contact with the bricks on either side of the weep hole.
