How To Prevent Mold Buildup On Your Home’s Windows


Mold spores can carry harmful toxins that can damage your health and shorten a window frame's lifespan. Fortunately, keeping your windows free of mold and mildew is easy to do. In today's guide, we'll share some essential tips to help you guarantee your windows are clean and safe all year long!

What Causes Mold To Grow Near Your Windows?

Windows are some of the most common places molds begin to grow. This situation becomes more of a problem in naturally damp environments like bathrooms or during the colder months.

The extra condensation buildup that drips to the bottom of your windows creates a hotbed for mold and mildew to thrive in the surrounding area. While black mold is the most common one you'll see, plenty of other types are equally harmful to your windows and home. 

Is The Mold Around My Windows A Health Hazard? 

Allowing mold to grow for too long can damage your home's air quality and negatively affect your health. It can also cause unwanted side effects, especially if you have asthma or mold-related allergies. According to the CDC, symptoms like sneezing, coughing, or shortness of breath aren't uncommon in people exposed to moldy environments for extended periods. 

How To Easily Keep Your Windows Mold-Free

Keeping your windows mold-free is relatively simple as long as you keep on top of it. Here are a few tips to prevent mold and mildew from growing, no matter what time of year it is:


     Dust Your Window Frames Weekly: Since mold spores can grow from dust particles, adding regular window dusting as part of your cleaning routine is essential to keep them looking spotless.


     Install Extractor Fans In Your Home:  Using an extraction fan in rooms prone to mold will keep the air flowing, reduce humidity levels, and prevent condensation from building up on your windows. 


     Invest In High-Quality Windows: When you invest in windows with higher-quality frames and glass, they tend to require less maintenance than cheaper products. For example, we make our CONSERVAGLASS™ NXT with Stay-Clean Technology windows repel water and stay clean for much longer.

Covid-19 Changes Spending Habits

We all have seen the detrimental effects the COVID-19 pandemic has had on our communities.
