What are Basement Weep Holes and Why You Need Them
Basement weep holes are small openings in the foundation of a building that allows water to escape. If they are not installed, water can build up and cause damage to the foundation and basement of a structure. In this guide, we will discuss what weep holes are, why you need them, and how to install them properly.
What is a Basement Weep Hole?
Basement weep holes are drilled holes in the foundation wall that allow water to drain from behind the wall. The holes are usually located at the bottom of the wall, and are covered with a wire mesh to keep insects and other small animals out.
Wet basements are a common problem in homes. Water can enter the basement through cracks in the foundation or walls, around windows, or from condensation on cold surfaces. A damp basement is not only unpleasant, but it can also lead to mold and mildew growth, which can be harmful to your health.
One way to prevent water from entering your basement is to install weep holes. Weep holes allow water to drain from behind the wall, preventing it from building up and causing damage.
How do Basement Weep Holes Work?
Basement weep holes are drilled near the bottom of your foundation, about six inches above the footing. Weep holes allow water that has entered the brick to drain out, preventing it from seeping into your basement.
If you don’t have weep holes in your basement, water can seep through the cracks in your foundation and cause serious damage to your home. Water can cause mold and mildew to grow, which can lead to health problems for you and your family. In extreme cases, water can even cause your home’s foundation to collapse.
Don’t take chances with the safety of your home – make sure you have basement weep holes installed by a professional contractor. It’s a small investment that could save you a lot of money in the long run.
Why Do You Need Basement Weep Holes?
While a few drops of water may not seem like a big deal, over time, even a small amount of water can cause serious damage to your home. If water is allowed to build up behind your foundation walls, it can eventually lead to cracking, bowing, and even collapse.
Basement floor cracks, wall cracks, and foundation settlements are all signs that water is damaging your home.
Here are a few benefits of installing weep holes in your basement:
1. Prolong the life of your foundation
Weep holes can help to prolong the life of your foundation by allowing water to drain away from the wall. This will prevent the water from seeping into cracks and causing damage.
Weep holes are also beneficial in that they can help improve the air circulation around your foundation. This can help prevent mold and mildew from forming, which can cause even more damage to your home.
If you live in an area prone to flooding, weep holes can also help reduce the amount of water that enters your basement during a flood. By allowing the water to drain away from the foundation, you can minimize the amount of damage that is caused.
2. Prevent damage to your basement walls
Basement weep holes are essential in the prevention of damage to your basement walls. Water can seep into cracks and crevices in your foundation and cause serious damage over time. Basement weep holes allow water to drain away from your foundation, preventing it from seeping into the cracks and causing damage.
If you don’t have basement weep holes, you’re at risk of serious damage to your foundation. Weep holes are essential in the prevention of water damage to your home. Make sure your home is protected by getting proper weep hole installation.
3. Preserve the value of your home
By keeping your basement dry, you are also protecting your investment. A wet basement is not only uncomfortable, it can also lead to the development of mold and mildew, which can cause serious health problems. In addition, a damp basement is an ideal environment for termites and other pests that can damage your home.
Weep holes are an important part of any basement waterproofing system, and can help you avoid these problems. By allowing water to drain away from your foundation, weep holes help keep your basement dry and comfortable, while protecting your home’s value.
4. Prevent Mold and Mildew
As previously stated, mold and mildew can cause serious health problems, so it’s important to keep your basement dry to prevent them from growing. Basement weep holes help ventilate your basement, and allow any moisture that does get in to escape, which helps to prevent mold and mildew from developing.
In addition to preventing mold and mildew, ventilation also helps to control humidity levels in your basement. By allowing fresh air to circulate, you can help keep the humidity in your basement at a relatively comfortable level, which will also help prevent musty odors.
So if you’re looking for a way to improve the comfort of your home and protect your investment, consider installing basement weep holes.
5. Installation is easy and inexpensive
One of the best things about basement weep holes is that they are easy and inexpensive to install. You can do it yourself with a few simple tools, or you can hire a professional contractor to do it for you. Either way, it’s a relatively small investment that can have a big impact on the comfort and value of your home.

When are Weep Holes Beneficial?
If your foundation is made of concrete masonry units (CMUs), also called cinder blocks or concrete blocks, weep holes are beneficial. Weep holes allow for drainage and help prevent hydrostatic pressure from building up against your foundation walls. However, when water seeps through the porous concrete block walls, it can eventually lead to cracking and bowing of your foundation walls.
Weep holes are beneficial if:
- Your foundation is made of CMU blocks or hollow blocks.
- You live in an area with high rainfall or flooding.
- Your home is located on a slope.
- Your basement frequently leaks.
If any of the above apply to you, weep holes may help improve the drainage around your foundation and prevent water damage.
How are Weep Holes Installed?
Weep holes are typically installed during the construction of a new home. The builder will create openings in the mortar joints between the CMU blocks to allow for drainage.
For an existing home, weep holes can be added by a qualified contractor. They will first need to determine where the best location for the weep holes would be, and then drill or chisel out openings in the mortar joints. It is important that they do not make the openings too large, as this can weaken the structure of your foundation walls.
In some cases, an interior drainage system may be installed in addition to weep holes instead. An interior drainage system is a network of pipes that are installed on the floor and walls of your basement.
Once the weep holes have been installed, they need to be covered with a corrosion-resistant material, such as wire mesh or plastic, to keep insects and other animals from entering your home.
Frequently Asked Questions
1
What's the purpose of a weep hole?
Weep holes are designed to provide drainage for water that gets behind your brick wall. Without weep holes, this water would have nowhere to go and would eventually cause the mortar between your bricks to crack and crumble. Weep holes allow water to drain out of your wall, preventing damage to the mortar and prolonging the life of your brickwork.

Why do I need them in my basement?
If you live in an area with a high water table or get a lot of rain, chances are you’ve had some problems with moisture in your basement. Water can seep through cracks in your foundation and build up behind your walls, causing all sorts of problems like mold, mildew, and rot. By installing weep holes in your basement, you can allow any water that gets behind your walls to drain out, preventing it from causing damage.

Should I drill weep holes?
It’s best to leave the drilling of weep holes to a professional. Weep holes need to be drilled at the right angle and depth in order to function properly, so it’s best to leave it to someone who knows what they’re doing. A professional will also be able to seal up the weep holes after they’re installed, preventing any insects or other pests from getting into your home.

Why does my foundation have holes in it?
If you’ve ever taken a close look at your foundation, you may have noticed that there are already holes drilled into it. These are called “weep holes”, and they’re there for the same reason as the ones you would drill in your basement – to provide drainage for water that gets behind your walls.
However, these weep holes can become clogged with dirt and debris over time, preventing them from doing their job. So, if you notice any of your foundation’s weep holes are plugged up, be sure to clean them out so they can continue to do their job.
A basement weep hole is a small hole drilled into the mortar between bricks to allow any moisture that has accumulated on the wall to drain out. This is an important preventive measure to take in order to avoid any water damage to your home.
If you live in an area with high humidity or rainfall, it is especially important to have these holes present in order to keep your basement dry. Contact a professional if you are unsure how to install weep holes in your home properly.
