Symptoms of High Humidity in Home


There are three things that mold needs in order to grow: moisture, darkness, and food. The wood and sheetrock in your home are food for mold. And your home is full of dark crevices and spaces, like behind walls and in crawl spaces. So the only real way you can combat mold is to remove moisture, and keep humidity below 60%.

Wood-Destroying Pests

Just like other animals, wood-destroying insects need water to live. Crawl spaces in North Carolina are notorious for bringing in warm, moist air and then trapping that moisture. This creates condensation and even pools of water in your crawl space, which can attract wood-destroying insects. Getting your crawl space clean and dry helps deter wood-destroying insects.

Wood Rot

Wood rot occurs when enough moisture is retained in the wood, whereas bacteria is able to start eating and destroying it. This is why lumber created for construction needs to be dry – so it won’t rot! When you allow moisture to build up in your crawl space, you’re letting it infiltrate the wood, which can lead to wood rot.

Uncomfortable Air

It’s that feeling when the air is thick and heavy, making it hard or impossible to cool off. When you’re hot, you sweat. And that sweat slowly evaporates into the air as moisture, taking heat with it and cooling you down. But when there’s a lot of moisture in the air, your sweat doesn’t evaporate as fast, so you feel hotter and sweatier. Dehumidification removes moisture from the air, allowing your sweat to evaporate.

Smells & Odors

Foul odors are often associated with moisture and humidity. These smells can bleed through walls into other spaces, at times causing rooms or the whole home to reek!

Health Issues

Smelling mold and mildew means that it’s in the air and getting into your body. People can quickly develop sinus and breathing problems and can even be hospitalized! For those who have asthma or other respiratory issues, dehumidification is a must.
