Damp basements are not just an eyesore; they can also spell trouble for any belongings that you have in there, as well as the structural integrity of your home’s foundation. While most basements are more humid than other levels of a house, an excessive amount of moisture needs to be professionally fixed before the home starts falling apart.

Watch for these signs of too much humidity in your home’s basement. If you detect any of them, contacting a Des Moines basement waterproofing service provider can help to stop any further problems caused by the moisture.


Condensation on your basement’s windows is a common sign that there is too much humidity in the space. As the condensation drips, it may start rotting the wooden framing or casing around the windows. The drips of water can also damage the concrete blocks of your home’s foundation. Puddles formed by the condensation may attract insects like carpenter ants and termites, especially if the water soaks into wood.

Mold and Mildew Growth

Mold and mildew growth in your basement are clear indicators that there is too much moisture in there. Mold and mildew may grow in streaks or in spots, and are most commonly found around windows, near the intersection of the basement floor and walls, and on paper or cardboard items stored inside of the basement. Once the moisture problem in the basement has been fixed, then the mold will need to be removed as well.

Water Stains

Excess basement humidity may cause water stains on your basement walls. These stains look like streaks of rust. Over time, the basement’s walls may develop efflorescence. This is a process in which the layers of concrete start to change color and flake off, leading to structural damage.

Musty Odors

Mold and mildew growing in the basement leave musty odors. The moisture can also cause a breakdown of organic materials like paper, which also produces an odor. The musty odor may cause you to sneeze and sniffle when you spend time in the basement, and the odor may drift into the living areas of your home.

To ensure that the humidity level in your basement will remain low, hire a Des Moines basement finishing expert who knows exactly what to do to make all surfaces moisture-free at all times. Don’t settle for anything less than a dry and comfortable basement, especially that it is one of the most functional rooms in your home.
