Mortar Net Weep Vents FAQ’s

Can I leave my weep holes unsecured?

You can, but your walls will have no protection against pests or damaging moisture, and you may be called back to the job site to perform costly repairs. Not to mention the headaches of trying to appease unhappy clients.

Can I use caulk and mortar instead?

No, weep holes should never be sealed with caulk and mortar only. Holes are still necessary to drain water and ventilate the space.

Can I use steel wool instead?

While traditional steel wool may be used, it will need to be refilled regularly as animals will pull the material from the wall to gain access. The permanent adhesion of these weep vents prevents that problem from happening.

How many inserts are required for my project?

Depending on the scope and requirements of your specific project, many experts typically recommend placing weep vents above doors, windows, and every 16 to 24 inches on walls.
