Weep holes in your window can become clogged with debris. If you weep holes are clogged, water trapped in your window frame can rot away the wood and damage the window. To avoid this from happening, you will want to check if your window weep holes are clogged.

To check if your window weep holes are clogged, you will need a glass of water and a flat spatula. You will want to see if you can get water to flow out of the weep holes.

Press the spatula against the glass of the window so that it is in position to direct water to the edge of the window. Slowly pour water on the spatula and lead it to the edge of the window.

If you see water pouring out of the weep hole, then you know that your weep hole is clear of debris. If you don't see any water coming from the weep hole, it may be clogged, and the water is stuck inside. You will need to unclog your weep hole if this is the result.

How Do You Unclog A Weep Hole?

If you need to unclog your window's weep hole, there are a couple of methods you can try. The first method uses a toothpick and water.

Let's go over each method to learn how to unclog a weep hole.

Toothpick And Water

All you will need for the toothpick and water method is a toothpick and water.

The first step is to take the toothpick and scrape as much debris as you can out of the weep hole. Once you have used the toothpick, pour water down the side of the window into the frame. The water should push any additional debris to the weep hole entrance.

From there, you should remove more debris with the toothpick. Once you have removed as much junk as you can, once again flush it with water.

The trick is to repeat this process until water flows smoothly from the weep hole.

Now let's learn about the compressed air method.

Compressed Air Method

With the compressed air method, you will need a can of compressed air. In this method, you press the nozzle of a compressed air can against the window frame entrance and blow the debris out with air.

With this method, it can be helpful to alternate from spraying the compressed air through the window crack or the weep hole. If you keep alternating, difficult to get debris will eventually make its way out of the window frame.

Can Bugs Get In Through Weep Holes?

While letting water out of your window is essential, weep holes have another considerable downside. Weep holes do allow bugs into your home. Small bugs can enter through the weep hole and get into the outer edge of your window frame and from there into your home.

While no one wants bugs entering their home, you can't block the weep holes. If you block the weep holes, you will defeat their purpose, and your window frame could rot.

There are a couple of solutions to keep bugs from getting in through your weep holes. Let's look at some of these solutions.

Weep Hole Screen

One solution to keep bugs from getting into your home is putting small screens over your weep holes. As long as the screen allows water to escape from your window frame, your window will not be damaged.

One downside to using weep hole screens is that they can make it harder to clean out your weep holes. They may also make it more difficult for water to escape the window frame.

Bug Spray

Another solution to keep bugs from entering your home is spraying the outside of your windows with a pesticide. This will create an invisible barrier that will kill bugs attempting to enter your home.

One downside of bug spray is that it may leave the bugs dead in your window frame. When you use bug spray, the poison won't kill the bugs until they enter your window frame. This may cause an accumulation of bugs in your window frame that will need to be cleaned out periodically.
