How to Prevent Humidity in a Basement

Prevent Humidity in a Basement

The basement can be one of the hottest places in the house.

It often does not have the same amount of airflow as the rest of the house, and warm air can get stuck down there quite easily. Having a comfortable basement and having a humid basement are not compatible at all. Here are a few ways to prevent humidity in your basement:

Use Exhaust Fans

Exhaust fans can help reduce humidity by circulating air. You don’t necessarily have to run exhaust fans only in your basement, and running them in any bathroom or kitchen can be helpful. This is because hot showers and cooking can increase basement humidity levels, as humidity tends to get caught there. You don’t have to run them all the time, and it can be exceptionally beneficial to run them during a shower or while cooking.

If you don’t have exhaust fans or the means to purchase exhaust fans consider opening your windows while showering. This can help increase airflow and dilute the hot air.

Use a Dehumidifier

Dehumidifiers are relatively cheap and easy solutions to reducing humidity in a space. They are not permanent solutions but can be useful for a short period of time. When positioning a dehumidifier, make sure that it is in the most humid and damp part of your basement. Make sure you maintain it properly and empty the reservoir every other day. If your basement is large or exceptionally humid, you may need two humidifiers or even three to handle the problem.

If a humidifier is too expensive of an option, consider buying one that has been refurbished or thrifting one. Used humidifiers are relatively cheap and usually work just as well.

Clean Your Gutters

Water from outside the house can frequently build up in and around the base of the house in the form of groundwater or precipitation. By taking care of your gutters and ensuring that they are functioning well, you can decrease the chance of collecting water and increasing humidity.

Be Conscious of Leaks

Leaks in the house and plumbing problems can increase your interior moisture quickly and lead to a high amount of humidity. Excessive humidity that builds up quickly is often a product of this. Some of the most common leaks are plumbing leaks, which can leak through the floors and cause water damage and wet spots on the basement ceiling.

Frequently, leaks can occur that aren’t visible. It is essential to check your water meter reading consistently to make sure that nothing is leaking that you may not know about. If you find out that something is leaking take steps to fix it or hire someone to fix it immediately


Keeping your basement cool and comfortable can be critical to creating a space that you want to spend time in. If none of these solutions help reduce the humidity in your basement, there are more tips at either at or
