Does brick veneer need weep holes?

Moisture can penetrate the surface and at siding junctions. You may have noticed that bricks don’t have eyes. Bricks can’t cry. Therefore, brick veneer walls require weep holes to permit moisture to escape from behind the veneer and to allow gaps between the brick veneer and the exterior sheathing to dry.

Why do brick walls have weep holes?

Weep holes provide ventilation as well as drainage. The holes you see lead to an air cavity that lies between the home’s exterior sheathing and the bricks themselves. The cavity is about an inch wide, and the air that naturally flows through the weep holes in brick helps to reduce the moisture level in the air cavity.

Where should weep holes be located?

Weep holes are typically found in the outer masonry leaf of cavity walls, just above the flashing. They can also be found above windows, doors or other penetrations. They should be provided at regular intervals so as to allow any moisture collected by cavity trays to escape.

Are weep holes required?
