Close up of a red brick wall above a concrete foundation, with two metal coiled weep hole covers fitted into the vertical mortar joints of the bottom brick row.

This photo shows the bottom row of brick on a Frisco home, where our tech installed metal weep hole covers in two of the mortar joints. Weep holes are left open so moisture can drain from behind the brick, but that open gap is just wide enough for mice and other pests to slip into the wall. The covers keep the drainage working while blocking that way in.
