TL;DR
A weep hole is a small, deliberate opening at the bottom of a wall or frame assembly, in brick veneer mortar joints, retaining walls, window sashes, and storm sills, that lets water trapped behind or inside the assembly drain out. In brick veneer they appear every couple of feet in the first course above flashing, draining the cavity behind the brick; in windows they empty the sill track outward.
What it means
A weep hole is a small, deliberate opening at the bottom of a wall or frame assembly, in brick veneer mortar joints, retaining walls, window sashes, and storm sills, that lets water trapped behind or inside the assembly drain out. In brick veneer they appear every couple of feet in the first course above flashing, draining the cavity behind the brick; in windows they empty the sill track outward. Sealing them during painting or caulking is a classic homeowner mistake that backs water into the wall, while inserts and screens exist to keep mice and wasps out without closing the path.
