How to Deodorize Your Basement

Basements are prone to moisture because of their location below ground. In your home, water can seep from the outside into your basement through a leak in the foundation or through small gaps around windows or doors. Dampness in basements can also be caused by moisture migrating through your concrete basement floor if you don’t have it protected by a basement floor moisture barrier. As that moisture evaporates, you may notice higher levels of humidity or even an environment that can be prone to mildewing.

Where there’s mildew, there’s also an unpleasant musty smell. Deodorizing your basement starts with removing causes of moisture while also taking actions to protect it from future moisture exposure. Here’s how to deodorize your basement:

    • Reduce the risk of mildewing by keeping moisture from creeping in through your concrete floor and walls by finishing the floor with a basement floor moisture barrier, like Floorguard®, and then also covering the walls with a moisture-resistant coating.


    • Dry out the basement by running dehumidifiers to remove excess moisture from the air. If your basement has windows, open them and use a fan to circulate fresh air into the room for a few hours.


    • Give your basement a good cleaning, taking care to get under appliances, in corners, and around vents. And don’t forget about any upholstery!


And finally, place a couple of opened containers of baking soda around the basement to keep the musty smell away. With these tips, and a little hard work, you should have a fresh basement in no time!
