How To Prevent Mold On Your Window Sills

How To Prevent Mold On Your Window Sills

Our windows can be more moist than we’d like to admit. With changes in humidity, precipitation, and just general aging, your windows can slowly begin to show wear-and-tear but you may not notice. Have you ever cleaned your windows and then realized just how dirty they had become? It’s a gradual process, and one that can allow mold to start creeping in.

Today we’re going to talk about mold and your windows. How can you tell if you have mold? How can you treat or stop the mold growth? And finally, how can I prevent future mold from living on my windows? Read on for these critical window tips.

Do I Have Mold?

It’s very possible that you could have mold growing on your windows without knowing. The mold can be the same color as your frame, and much of it can be within the sash edge, or the surrounding wood if you have wood window frames.

Check the edges of your window where the glass meets the window sash frame. Do you see any discoloration or clouding? It may be an indication of mold. Mold can be harmful to your family’s health, but it can also weaken your window frame, and need to be eradicated.

How Do I Remove Mold?

It can seem excessive, but always start by protecting yourself, as spores from mold can be inhaled, ingested, or carried. This means you should wear goggles, gloves, and a mask. Then spread out a plastic sheet around the window to catch any mold that might fall away. Opening the window or door can help with the ventilation, too.

Create a bleach and water mixture of one part bleach to three parts warm water. Then using a sponge, brush, or rag, begin scrubbing the moldy areas. It’s important to choose soft tools so you don’t scratch your window – so only use the soft side of a sponge or a soft brush. Once you’ve loosened the mold, wipe it clean and allow for complete dryness before using the window again.

How Can I Prevent Window Mold?

The best way to prevent window mold is to minimize moisture. Many older windows allow far too much moisture and precipitation to leak into a window or sill.

It may be time to consider a replacement window that a better sealed window, especially in an older home or for kitchens and bathrooms which experience more moisture and humidity.

It’s also a good idea to regularly clean your window sills, even when they appear clean, since dust can attract moisture and mold.
