5 Easy Tips To Prevent Mold Growth on Your Window Sills
1. Clean Regularly
Mold grows in dirty, damp, and dark places. Your window sill is constantly exposed to regular wear and tear and becomes filthy. Therefore, it is necessary to dust off your windows daily with a broom or brush.
Use a mild soap and damp cloth to remove any stains. If mold has already grown on your window sills and returns after regular cleaning, treat it using hydrogen peroxide, baking soda, or undiluted vinegar.
Once removed, keep the sills clean to prevent the growth of mold spores.
Remember not to clean your window sills with a dripping cloth that can build moisture n the surface of your window frame.
2. Maintain Humidity Level
The humidity level around your window sills plays a primary role in producing moisture. During summers, the humidity level should not increase above 50-60%, and in the winter, it should be less than 40%.
To maintain a proper humidity level during hot weather, install a dehumidifier and use it to remove extra moisture. Also, use humidifiers to reduce the effects of condensation in the winter.
Still, if you see any condensation buildup on your window sill, wipe it off to stop the spread of mold spores.
Do not forget to clean the tank and base of your humidifiers and dehumidifiers to prevent the growth of bacteria.
3. Ensure Proper Airflow
Another factor that affects your home’s moisture level is your ventilation system. Keep your ceiling vents open in hot weather to prevent moisture from accumulating inside your house.
Additionally, make it a daily habit to open your windows and doors to allow a proper flow of fresh air around your window sills.
If you are not running your heating or cooling system, keep the ceiling fans on auto to enable positive airflow and constant temperature.
4. Fix Cracks or Splits in Your Window Frame
Any crack or split in your window sill can allow rainwater and moisture to penetrate. This will not only promote mold growth but also damage your surface internally.
So as soon as you see a crack or split in your window sill, get it fixed immediately. You can fix small cracks on your window sill using a non-hazardous silicone caulk.
Before applying any sealant to your window, wipe off the surface and let it air dry to ensure no moisture is left inside.
5. Fix Water Leaks
If your window sill is leaking, you need to fix it immediately. Any water leakage in your home is dangerous and prone to mold growth.
If the leakage comes from the frame or sill, you can fix it with silicone sealant. And if there is any crack in the glass of your window, it must be replaced to stop the water from dripping.
