ASK DANNY: What Should I Do About These Weep Holes?

Homeowners should keep all their weep holes open because they’re there for a reason, Danny says.

Hi, Danny,

I was flooded during [Hurricane] Harvey and one side near the living room — which the wall has windows almost to the floor — is where most of the water came in.

My contractor says it will not hurt to completely seal as there [are] enough [weep] holes on either side of the house. At this point, [it] is approximately 25 feet across.

Do you know of a good permanent filler for these holes?

Hi, Patti,

It’s never a good idea to seal brick weep holes because they’re there for a very important purpose: allowing moisture to escape from between the brick wall and your stud wall.

However, if you decide to do so, I would recommend using mortar to match your existing mortar.

A much better alternative would be to work with a landscape contractor, who can divert the water and prevent it from being able to rise and enter the house at that point.

While you should never fill weep holes with solid material—such as caulk, wood, or mortar—you can put strips of fiberglass screen wire or scouring pad in the weep holes to keep insects out.

Thanks for your question.

Danny

    • Hi, John! Provided the new weep holes still allow moisture to escape from between the brick wall and your stud wall, we can’t see why not. Just follow the instructions in this article, too. Good luck!

  1. What would make holes in our cement patio. Looks like a bug drilled right through the cement. Just started seeing them. They are getting deeper and more are showing up. We just had our house repainted about 3 weeks ago. I don’t know if the last earthquake did anything
    We have a swimming pool and most of the holes are on that decking around pool Do you have any ideas on what it might be?

  2. In August of 2016, we had water come in our front two bedrooms due to flooding in area caused by heavy rains. (33″ in 24 hours). The water came in from the weep holes in our brick and underneath the base boards. I understand the reason for weep holes, but my question is this: if there are open holes in the brick of my home, then rising water will enter it and flood the inside of the home, so, why cant we temporarily plug those weep holes until after the flooding goes down? It could be a day or 2 or even 3 days before the water goes down. Thank you!

  3. Recently I realized I have 3 week holes which have been covered by surface soil elevation. I’ve dug down 7 bricks to the deepest weep hole.
    What I would like top know, would it work if I cut a length of PVC pipe in half and glue or to the brick and the replace dirt to current elevation. The purpose is to prevent such a deep elevation change to expose these 3 weep holes because it’s very close to my garage drive.
    The longest piece of PVC pipe glued to brick would be approximately 10′.
    Thank you for your reply.
