If you spot mold on the windowsill, don’t panic. While window replacement may seem like the best solution, there may be other ways to address this potential concern. The guide below explains what you can do about the issue. 

Window Mold 101

What Causes Window Mold?

Mold thrives in dark or moist areas. Spores often grow around window frames despite the sunshine, as precipitation and humidity can build up due to inefficient ventilation. This may occur gradually over time, particularly in older frames made of materials susceptible to rot, like wood. It can also sometimes indicate a leak is causing more rapid damage. 

How Can You Get Rid of It? 

The best way to mitigate mold is to remove the glass panes and clean the frame, casing, sill, and other affected parts with a mixture of water and bleach. Handle the panes delicately to avoid breakage and wear gloves for your protection. Inspect the area in case there are more significant issues at hand, like a warped frame that’s encouraging water infiltration. Look at the roof and wall for signs of water damage, such as peeling paint and mold, as you may need a repairman to fix an underlying leak. Use caulk to seal any gaps and dry each part with a soft, clean cloth before putting the glass back. If the rot has reached deep into the frame, consider getting a window replacement to mitigate the mold, limit the likelihood of additional moisture problems, and improve the air quality in your home. 

How Can You Prevent It?

It’s essential to maintain low humidity levels at home to prevent mold growth. Install a dehumidifier to use during the summers to limit the likelihood of mold growing on the windows. Check your windows periodically for issues, and have your gutters cleaned and inspected at least once a year to minimize the risk of water damage. If you live in an older home, consider upgrading with a window replacement that offers enhanced protection, like double panes or fiberglass frames.
