Are you worried about the regular occurrence of mold on your windows? Is it difficult for you to get rid of the window mold? The occurrence of mold on windows is very common, so it is important to know why and how to resolve. The two most common causes of window mold are the expected condensation (humidity) problem. The other is a more significant problem with the exterior of the home around the window.
When there is humidity in the air despite the cold weather, and AC doesn’t run for some time, and there’s simply no way to get rid of internally developed humidity, then condensation occurs. Condensation is the leading cause of window mold. Since mold loves the condensed, humid, and wet environment, they start gathering on the outlines of windows where moisture settles more than other places.
The other common cause of window mold is inadequate flashing and caulk around the window exterior and siding. We have seen newly constructed commercial properties and homes with extensive window mold problems due to the installers not properly flashing and caulking during installation. Most of the time, when this is the problem we see mold on the wall underneath the window versus inside of the window casing like it is with condensation. We recommend all newly constructed properties or properties with a recent window or siding installation to be inspected by a third-party contractor after installation is complete to ensure correct installation procedures were followed.
The window and wall surfaces get warmed by the natural air convection currents when the external temperature is lower than the internal. As a result of this, the room air accumulates on the window surfaces which cause the air that is present on the windows to cool down; thereby making it denser and causing condensation. When condensation increases, humidity in the air also increases mold more than anything. To avoid this, you can raise the room temperature that in turn increases the surface temperature of the air at the window surfaces that helps in reducing condensation.
Mold thrives during nights due to darkness and overnight condensation. Wipe off the windows every morning to put a cessation to window mold growth. By doing so, you eliminate the water that is necessary for their growth. The dust particles along with other food sources are also removed.
To control windows mold growth, you have to put a limit to the humidity in the air. For that, the dehumidification equipment works best. This equipment filters out the moisture in the air and brings in the deeply dehumidified air. Since moisture is the key reason for mold growth, the less it is in the air the better. We advise you to get a dehumidifier with an auto pump so that it could drain and you don’t have to worry about emptying it daily.
