Tips for How to Get Rid of Moisture in Basement Areas

1. Fix the Slope Around Your House

If you’re wondering how to get rid of moisture in basement, you have to understand how it’s getting there in the first place.

One way it might be entering your home is from outside, either because of rain, snow melt, or your sprinklers.

You’ll need to check your property and see how the land slopes. If it’s angled toward your home, then this means that rain, snow, or water from your yard is being directed into your basement. That could lead to excessive moisture, dampness, and humidity, as well as mold growth.

To ensure that water doesn’t get into your basement and wreak havoc, the slope around your house should be angled so that water flows toward the yard or street and away from your property.

If you can gain access to topsoil or dirt and reslope the area around your house, this can solve a lot of your problems. If not, getting this fixed will require a helping hand by a lanscape professional.

2. Place a Plastic Barrier on the Ground

Another way that water or moisture can get into your basement is up through the ground.

If you have a dirt floor in the basement, you might need to place a plastic barrier on the ground. The moisture will still exist, but it won’t be able to penetrate the plastic, keeping your basement drier and less humid.

3. Use a Dehumidifier

This appliance works by pulling excessive moisture out of the air and collecting in a bucket or directing it down a drain.

4. Use an Air Purifier

In addition to a dehumidifier, you should also invest in an air purifier. While this machine doesn’t necessarily remove water from the air, what it does do is filter out the harmful particles that are floating around in it.

High moisture content inevitably leads to mold and mildew growth. And air purifiers can extract the mold spores out of the air and trap them inside a filter and/or kill these microorganisms so they don’t lead to health complications.

Waterproofing your walls can be beneficial if you’re looking for a permanent solution for how to get rid of dampness in basement.

Since cold water pipes are colder than the environment around them, they’re commonplace for condensation to form.

10. Extend Downspouts

If the downspouts on your home aren’t pushing water far enough away from your foundation, then when water runs off your roof, it could find a way into your basement.

When it rains or when snow or ice melts, this moisture has to go somewhere. And you want to make sure that it’s not into your basement.

Extending your downspouts is a quick fix for this common problem.

The downspouts should extend at least six feet away from your house. It’s also a good idea to check the slope around your home to ensure the water continues to flow away from your property and not back towards it.

When it comes to getting downspout extenders, you should be able to find these at retail stores or online and affix them yourself. However, if you prefer to have assistance from a professional, you always have that option.
