Maçonnerie Montréal's Comprehensive Guide on Weep Hole Repairs

Delving into the World of Weep Holes

At Maçonnerie Montréal, we pride ourselves on our meticulous attention to every brick and mortar detail. Weep holes, often overlooked, play a pivotal role in maintaining the health of masonry structures. These small openings ensure that trapped moisture behind brick walls can escape, preventing potential structural and cosmetic damages.

The Anatomy of a Weep Hole

Before diving into the materials used for repairs, it's essential to understand the anatomy of a weep hole:

  • Position: Typically located just above the foundation, at regular intervals.
  • Size: Generally, a weep hole is about the size of a standard pencil, allowing for optimal drainage.
  • Function: Beyond drainage, they also ensure that the wall can breathe, reducing the risk of mold growth and brick erosion.

What Materials Are Used in Repairing Defective Weep Holes?


Mortar is the primary material used in masonry. When repairing weep holes, a specific type of mortar, known for its durability and adherence, is chosen. This ensures that the repair is both long-lasting and effective.


In cases where the surrounding brickwork has been damaged due to a defective weep hole, it's essential to use bricks that match the existing structure in both color and size. This ensures aesthetic consistency.

Plastic Weep Vents

These are specially designed vents that allow for optimal drainage while preventing pests and debris from entering the weep hole. They are durable, resistant to UV rays, and can be easily integrated into the masonry structure.

Galvanized Steel Wire Mesh

This is used to create a barrier, ensuring that larger pests, like rodents, cannot enter the weep hole. It's rust-resistant and can be easily molded to fit the weep hole's shape.


Water-resistant sealants are applied post-repair to ensure that the weep hole remains protected from external elements, further enhancing its lifespan.

The Repair Process: A Step-by-Step Overview

  1. Assessment: The first step involves assessing the extent of the damage. This helps in determining the materials required and the approach to be taken.
  2. Cleaning: The damaged weep hole and its surrounding area are cleaned to remove any debris or blockages.
  3. Material Application: Depending on the damage, the appropriate materials are applied. This could involve sealing the hole, replacing bricks, or inserting a plastic weep vent.
  4. Sealing: Once the repair is complete, a sealant is applied to protect the weep hole from external elements.
  5. Post-Repair Inspection: After the repair, an inspection ensures that the weep hole is functioning optimally.
