The moisture in the air in your home is known as humidity. It is important to ensure the humidity in your home is at the correct level. When the basement has too much humidity, it can cause a lot of problems. Because the support structure your home is built on is made from wood, the humidity can cause damage if it is left unchecked. The support beams, floor joists, flooring, and walls are all susceptible to rotting because of high humidity. A dehumidifier installed in the basement can be used to control the amount of excess moisture in the air. Additionally, this rotting wood will cause problems for the structural integrity of the home and may also become a home to unwanted pests, including termites and roaches.
