How to do it

  • 1

    Identify all weep holes (horizontal gaps at brick/sill interface) on the home's foundation perimeter.

  • 2

    Test each hole by shining a flashlight through; note any that are completely open or have failed screening.

  • 3

    Purchase ¼-inch stainless steel mesh (hardware store, ~$15 for 10 sq ft).

  • 4

    Cut mesh pieces to 2×3 inches; slide carefully into weep holes, ensuring debris-free contact with brick.

  • 5

    Secure edges with small stainless steel fasteners or non-hardening building adhesive; do not caulk over holes.

  • 6

    Re-inspect in spring and fall for gaps, pest droppings, or water staining.
