How to Prevent Mold Growth on Windows

Mold is a type of fungus that grows in damp or moist areas. For many homeowners, mold grows on the walls of their shower or in the dank unfinished basement. The fungus can also be found on window sills, appearing as a dark discoloration. When left untreated, mold can lead to serious problems – including damage to wood window frames and health complications – so it’s important to remove and prevent mold from returning.

What are some causes of mold on windows?

Condensation

Condensation forms when warm, moist air meets cool, dry air. For instance, when you walk into a heated building on a cold winter day and your glasses fog up. If left on a surface like your home’s windows, condensation can lead to mold growth.

The formation usually starts at the base of the window, where moisture tries to seep between the sash and glass. If this moisture enters the home, you could begin to notice water spots or peeling paint.

Old Windows

A home that lacks energy-efficient windows is an invitation for mold growth. If the airtight seal is loose or broken, moisture can easily find its way inside. For efficient performance and protection from the elements, your home may need replacement windows.

Dusty Interior Rooms

To prevent mold growth on the inside sills, make sure to keep your interior rooms clean. If there is a lot of dust buildup in the bathroom or bedroom, you could be opening these areas up to mold spores. Wipe down any damp surfaces on or around the windows and dust your home on a regular basis. Otherwise, it could become a breeding ground for fungus.
