Got Mold in Your Windows?

Have you noticed black spots or residues on the pane or sill of the windows in your home? This might not be dirt accumulation. Those black spots could be mold, a type of fungus that tends to grow in damp areas. When mold grows in your home, you could put both your property and your health at risk if you ignore it.

But what can homeowners do about mold on their windows? And how did it get there in the first place? Chesapeake Roofing, Windows, and Siding Inc., an exterior home improvement company located in Annapolis, MD, further illustrates the major problem of mold growth on the windows in your house.

Where Does Window Mold Come From?

Mold thrives in moist environments, so if you see mold growing on your windows, you may have a leak in or around the frame. Dust accumulation in conjunction with moisture can also contribute to the growth of mold on a window.

Another way to tell if your window frame or seal is broken and leaking is by seeing fog or condensation developing on the glass, especially between the panes. Even if the mold grows between the windowpanes rather than the inside of your house, it can pose a threat to your home.

How Does Mold Impact Your Home?

Black mold growth on your windows can make your home look dirty and unattractive, but it can be dangerous too. The mold can eat into the window frame if allowed to spread without treatment, causing severe damage to your window and further into the structure of your house. This may leave you with expensive repairs.

Mold is also toxic to humans. If you and the residents of your home continue to breathe the spores from the mold, you may be at risk of respiratory illnesses and other major health problems.

How Can I Prevent Mold Growing in My Windows?

Mold can usually be removed from a window by spraying the affected area with a mild detergent and scrubbing and wiping it clean. However, you can also prevent mold growth by ensuring your windows are cleaned regularly and clearing dust and other residues promptly. If the room is humid and creates condensation on the windows, consider using a humidifier to keep the room balanced.

If you notice a leak in your window, reach out to your local exterior home improvement expert for repairs or replacements. They can also inspect your property to ensure that mold or other moisture concerns have not caused significant damage to your property.
