Removing Mold from a Window

Preventing & Removing Mold from Your Windows

Spring has sprung and for many it means cleaning away winter's grime from our windows to enjoy the fresh brightness of the season. Windows can accumulate, dust, household toxins like smoke or cooking grease, and can even grow mold. Most people do not even realize they have mold growing on their windows. On most homes, mold begins to grow at the bottom of the windows at the joint between the glass and window frame. While window mold does not typically feed on windows themselves, it can destroy wood window frames.


While this can seem like a natural challenge in Canada, with its environmental temperature and moisture fluctuation, large amounts of mold can potentially be dangerous to you and your family’s health. Before you panic, here’s some information on how to identify the mold, get rid of it, and prevent it from happening in the future. 


When removing mold from your windows, understand that safety comes first, and always put on safety googles, gloves, and a dust mask so you don’t ingest the dangerous spores that the mold can release into the air as you ‘disturb’ it in the cleaning process. It is also very important that there is adequate ventilation in the room. Open a window or door so the mold spores can escape instead of staying locked in your home. Cover the floor under the window you’re cleaning to catch any of the falling mold.

Make a mixture of one part bleach to three parts warm water. Scrub the mold off of the windowsill using a non-abrasive brush and frequently dip the brush in the bleach mixture. Use a clean rag to then wipe away the mold you loosened. Allow the windowsill to dry completely before you close the window. Wipe off any remaining residue.

Leaking windows and condensation are the two leading causes for the buildup of mold on a windowsill. To prevent mold in your house, you need to reduce the amount of condensation on your windows. This can be done by: setting your air conditioning thermostat above 20 degrees Celsius, maintaining proper airflow in your home and regularly cleaning your home’s interior.

However, if your windows are no longer functioning properly, are broken, cracked, or simply no longer keeping moisture from your home, then perhaps the easiest way to prevent mold is by replacing your old windows. Your health and utility bills will thank you.
