Did you recently spot mold growing on your windows? Sometimes moldy windows are simply an eyesore requiring a minor cleaning project, but extensive growth that spreads throughout your home could easily cause health problems, including allergies and asthma.
By understanding why your windows are moldy, you can prevent the problem from recurring. In the meantime, you should either attempt to remove the mold or pursue a window replacement if the damage is too extensive.
Humidity and Condensation: Major Causes of Window Mold
High humidity, or excess moisture in the air, allows water droplets to condense on cold surfaces. This makes glass a susceptible surface for condensation. Winter is the time of year when window condensation is most likely to occur because cold conditions outside cool indoor air near the window. Cold air can’t hold as much water, so condensation forms as a result.
However, it’s not likely for mold to grow on the glass itself. Instead, water droplets roll down the window and settle on the sill. If you have unprotected wood windows, the water may not only encourage mold growth on the surface, but it can rot the wood as well.
Prevent Window Mold
The best way to prevent condensation on your windows and the resulting mold growth is to:
- Keep indoor humidity lower in the winter.
- Run kitchen and bathroom exhaust fans when cooking and showering to prevent excess moisture from condensing on the glass and potentially damaging your windows.
Remove Window Mold
If your windows are made of aluminum, fiberglass or vinyl, these non-porous materials are easy to clean. Simply apply a solution of bleach and water to remove mold from the surface. Make sure to wear rubber gloves to protect your skin.
If have wood windows, purchase a professional biocide to penetrate the porous surface and remove mold without damaging the wood. This technique also helps prevent mold from recurring. Apply a protective finish to the wood as an added precaution to protect it from rot if mold shows up again in the future.
