Some portions of my house have a brick veneer wall (that is, a brick wall that is not structural; cement blocks on the other side support the structure - please correct me if I am calling it the wrong thing).

There are no weep holes as far as I can see. I strongly suspect the former owner filled them up (as he did this sort of thing everywhere, like between the basement floor and foundation walls).

If I can locate where the old weep holes were, I can just open them back up I think. But if I cannot locate them, would it be totally stupid to drill some new weep holes in the mortar?

  • Can you see the bottom of the bricks?

  • @SteveSh, yes, the brick wall ends where a paved sidewalk deal begins.

  • Confirm that the brick ends above the sidewalk. Quite often a sidewalk is put in after bricks, so it is possible to be above the bottom bricks.

    You don't need weep holes for any walls that surround interior spaces (those should have a perimeter drain at the foundation). Only time you really need weep holes is for a (tall) retaining wall.

    @Huesmann, that's completely at odds with what I know about brick walls. Have a look at the office buildings you pass in the future. They'll often have weep holes (sometimes with string protruding).
