Weep Holes Continued

In the residential industry as a handyman, you will find a mix of brick and block (solid masonry) homes and brick veneer (wood frame and brick) homes right up to the early seventies. If no weep holes are present, check to make sure that the house is frame. If it is frame it will have a sill plate. If it is brick and block, it will not have a sill plate, the joist will be resting on the masonry. The very old brick and brick houses have weep ropes. The brick and block houses do not have weep holes. But the brick veneer houses should have them, of course, depending on the contractor that built them.
Having weep holes over the windows and doors will help provide better ventilation in the wall cavity. . If you have weep holes down at the bottom course of brick, then you have wall ventilation. I am referring to brick veneer. But if it is a brick veneer house and it does not have weep holes, this only tells me that I need to look for signs of moisture, because the conditions are right for moisture. Keeping in mind that gutters, overhang, and proper exterior drainage should also be considered.
Personally I would not recommend weep holes as a cure for moisture. In some cases this cure could be worse than the disease. You could end up just creating potential points of water penetration if you tried to add the weep holes now, after the fact. The reason for this statement is that weep holes are only the part of the back brick venting that you can see. But for back brick venting to do its job, it needs flashing, the vapor barrier to counter it, and the brick to be back parged every six courses (between wall tie heights). Okay, the point is always look for moisture, with or with out weep holes. Because even if you see weep holes it does not mean that they were installed correctly for back venting..
