What weep holes means
Weep holes are small openings at the bottom of a brick or stone veneer wall, right above the flashing, that let water out of the air space behind.
Also called weeps.
Where it matters on a masonry and hardscape job
Homeowners sometimes fill them to stop bugs, which traps water. Weep vents keep pests out without blocking drainage, an easy fix to offer.
What the model code says
- Weepholes go in the outside wythe at a maximum of 33 inches on center, at least 3/16 inch across, right above the flashing. (IRC 2021, Chapter 7)
Check which code edition your building department enforces for weep holes before you quote.
