Have you noticed black, dirty looking spots on your windowsill? This could be mold. Mold can grow anywhere moisture is found, and window condensation provides an excellent habitat.
Why does mold on your windowsill matter?
On top of making your windows look dirty, mold can pose health risks for those with allergies or respiratory illness. Mold should never be ignored, but thankfully mold on windowsills is easy to prevent. Here’s how:
Prep Your Windows with Mold-Resistant Paint
If your windows are clean, you can prevent mold before it starts with mildew-resistant paint or mold-resistant primer. Mildew-resistant paints include an antimicrobial that is FDA certified and proven to provide lasting protection. Just make sure that you do not paint on top of existing mold. If you do, the paint will not be effective.
Set Your Thermostat Below 70 Degrees
It’s not always practical to keep your thermostat set at a low temperature but doing so can slow mold growth. Mold thrives at temperatures between 77- and 88-degrees Fahrenheit, especially when the air is high in humidity. However, mold can grow at any temperature ranging from about 40- to 100 degrees Fahrenheit, so this method offers limited utility.
Run a Dehumidifier
One simple and surefire way to help prevent mold is to run a dehumidifier. Mold needs moisture to grow, and a dehumidifier removes access moisture from the air. However, it is important to note that mold can lay dormant during dryer climates, just to reemerge once moisture is reintroduced. So, drying out the air does not kill existing mold, but it can stop mold growth temporarily or help prevent it before it starts.
Maintain Good Airflow
As with running a dehumidifier, proper ventilation reduces moisture in the air that can lead to mold growth. You can improve the ventilation in your home by placing a fan in a window facing outward, using ceiling fans, and opening your windows. A well-maintained air-conditioning system is also important for keeping your home’s air clean and properly circulating.
Clean Your Windowsills Often
It’s easy to let this chore slip because your windows are often hidden behind window treatments, but one of the easiest ways to prevent mold growth on your windowsills is to clean them often. Whether you want to prevent mold or clean windowsills that are already moldy, mix a solution of one part bleach to three parts water. Use a misting spray bottle to apply the mixture then scrub the surface with a cloth or sponge.
Does mold on your windowsills mean it’s time for new windows? It might. Here’s why.
Some mold can be normal on windowsills, especially if they are not cleaned regularly. However, in some cases mold can be a sign of trouble. If your windowsills are worn out or if your windows fail to open and close properly, then it might be time for window replacements.
If this is you, make sure to find a reliable window company that offers quality products and professional window installations. Otherwise, you will find yourself in the same boat in no time.
