Ever noticed those tiny holes at the bottom of a window frame and wondered why they’re there?
They’re not a mistake.
They’re not damage.
And you definitely don’t want to seal them shut. 😅
They’re called weep holes.
A weep hole is a small opening built into windows, doors, brick walls, and masonry systems that allows trapped water to drain back outside.
Because no matter how well something is built, water always finds a way in.
The real trick is giving it a way out.
Why weep holes matter 👇
💧 Prevent water from collecting inside window frames
🏠 Help protect walls from moisture damage
🪟 Reduce the risk of rot, mold, and corrosion
🔨 Extend the lifespan of windows and building materials
You’ll commonly find them in:
• Vinyl and aluminum windows
• Brick veneer walls
• Sliding doors
• Masonry construction systems
Here’s a mistake homeowners make all the time 👀
They see a small hole and fill it with caulk.
Which is basically like plugging a drain and hoping the sink still works.
Once water has nowhere to go, it starts causing problems where you can’t see them.
Tiny hole.
Huge job.
