In order to keep your property in good condition it is important to prevent mold. While you might think that you are on top of any mold prevention you might not be looking hard enough. There are places that you may not think are susceptible to mold growth. One of which is your windows.

Windows are often not the first thing you check when performing mold inspection because we tend to think that this fungus only thrives in warm, damp places. Luckily we have provided you with some more information and tips to keep your windows free of mold growth this year.

How Can Mold Grow on My Windows? They are Constantly Exposed to Sunlight!

Like we mentioned above, many tend to think that mold growth only occurs dark and damp places. So you might be curious on how mold can grown on windows that are constantly exposed to sunlight. It should first be noted that the accumulation of dirt and dust from indoors contributes to mold growth. Mold spores, in particular, can sustain themselves when consuming bacteria, dust mites, dead skin cells, hair, pollen, and even some plastic particles. This means that even if they are exposed to heat, then they can still grow, and they may even thrive faster.

Black mold is the most common mold that you can see on windows. This fungus actually multiplies when you open the windows come springtime. Black mold has been growing during the cold months in fall and winter as it feeds on contaminants. The sunlight wasn’t as prominent, allowing it room to grow and spread around the houses, primarily through your heating system.

Prevent Mold from Growing on Your Windows:

Nobody wants mold growth, especially on their windows, where we look out everyday. So in order to avoid mold growth on your windows, you should first inspect your window sills, the glass, and the frames. Typically, the hiding place for mold is inside the sills and frames made of wood or aluminum because this is where the mold spores can seep in. Even though the glass is resistant to mold damage it can still accumulate in the windowpanes and hide there to avoid direct sunlight.

You should clean your windows with soapy water and a damp cloth once a week. To go above and beyond you will want to get into the nooks and crannies with a toothbrush. For that extra and thorough clean you can use your vacuum cleaner with the tiniest nozzle to suck out any of the dust. During the cold months you will want to do a biweekly cleaning because this is when mold growth is highly possible. It is also wise to have mold abatement specialists inspect your windows during the spring. Mold Inspection Near Me

Mold Removal from Windows:

You are able to address minor issues with mold growing in your windows. This is normally not as serious as it would be for other complications, like in spaces with intense water damage due to flooding. So here is a how to for at-home treatment:

Ingredients: mild bleach, a face mask, gloves, clean rags, a trash can, and some warm water.

Step 1: Mix warm water with one cap filled with bleach.

*Wear a face mask and gloves during the process*

Step 2: Then dip the clean rag into the water-bleach solution and use it on the moldy areas. Have the trash can ready to dispose of the dirty rags to reduce the risk of spreading the mold spores around your property.

Step 3: Repeat twice a week for all mold-filled windows until the mold is gone.

If you notice that the mold from the windows has transferred from the window to the drywall or sheetrock, don’t hesitate to call your TMG professionals since cleaning it by yourself won’t address the issue properly.


Although window mold might not seem like much concern or is something that can easily be dealt with, it is still something you shouldn’t overlook. This issue can endanger anyone in your home. If you feel that you cannot handle the mold situation on your own, seek professional assistance from experts like us.
