How to Prevent Mold on and Around Windows
Preventing mold growth on and around your windows is a surprisingly simple process. While each part of your window grows mold for different reasons or in different situations. Here are some of the best ways to prevent mold on different parts of your windows.
How to Prevent Mold on a Window Sill
Exactly what kind of mold grows on window sills? Window sills in most houses are either made of wood or aluminum. While mold requires the presence of organic matter and humidity to grow, it can be found on both wood and aluminum window sills.
The mold uses the organic matter present in household dust for sustenance. On aluminum sills, window sill mold around the window causes dust to settle and combines with moisture, creating the perfect environment for mold.
So, what causes mold on window sills? Mold around a window sill is commonly caused by dampness trapped in small crevices in or near the perimeter of the window, creating spores of mold and mildew. On wooden sills, the mold and mildew grow on the wood substrate as well.
In order to prevent this, you can paint wooden sills using a high gloss paint that protects the wood. Make sure you regularly dust your window sills as well, particularly when it’s been damp.
Preventing Mold on Glass Window Panes
Can mold grow on glass?
The glass panes of windows are not organic and should not cause the formation of mold. However, if the glass panes have not been dusted regularly, it can lead to mold inside the window pane.
Additionally, if moisture is trapped between the double panes of a window, this can cause mold between glass panes. Specifically, mold can in fact grow on windows; and usually, moisture accumulates there if your window seal is broken. At this point, you may need to consider getting new windows installed because you can’t clean between the window panes.
Moisture often collects between the glass panes of a double-paned window or on the indoor side of a window pane. The warm air indoors is cooled when it comes into contact with the cooler window panes, causing condensation. These double paned windows tend to look cloudy or foggy when condensation forms between the panes.
You can prevent the formation of mold on window panes by keeping the glass panes dry and dust free. Additionally, you can reduce the condensation on window panes by reducing the humidity indoors by using a humidifier.
Mold Between Window Panes
Mold can be a persistent and frustrating problem, especially when it develops between window panes. This can be caused by excess moisture or condensation that gets trapped within the window frame, creating a breeding ground for mold spores. Fortunately, there are several ways to prevent mold growth in this area. One effective method is to regularly clean and maintain your windows to keep them dry and well-ventilated.
This includes wiping down the frames and sills, as well as using a dehumidifier or fan to reduce excess moisture. Additionally, you can consider investing in newer, energy-efficient windows that are designed to minimize condensation and increase airflow. By taking these steps, you can help reduce the chances of mold growth and keep your home healthy and comfortable.
Preventing Mold in the Window Frame
Window frames, like window sills, are typically either made of aluminum or wood; and both types can develop mold. On aluminum frames, dust that is rich in organic matter can accumulate in the joint where the glass meets the frame. This joint can trap the condensation that exists near the windows, ensuring optimum conditions for the growth of mold.
On wood window frames, the moisture trapped near the joints of the wood and glass is enough to encourage the growth of mold. Damp wood is a very common food for mold. To prevent the growth of mold, make sure that the joint between the wood and glass is free of dust and moisture. Scheduling weekly cleaning of these parts of the window will help you stay ahead of it.
Preventing Mold in Aluminum Window Tracks
Modern window systems frequently have aluminum tracks that help the glass panes of windows to slide open and shut. However, these tracks can also accumulate dust and moisture more easily and can be difficult to clean manually. The accumulated dust and moisture leads to the growth of mold.
To make sure that the tracks of the window are free of mold and dust, they should be cleaned weekly. Dislodge the dust with a brush, then vacuum the dust up so it’s clean and dry. Many window tracks have small holes to enable the water to drain out of them.
However, these holes can become blocked with dust unless the tracks are cleaned regularly. If you find mold in the window tracks, you need to first remove the mold before cleaning the holes and dust off the tracks.
What to Do About Mold on Windows
Removing mold on your windows is usually fairly simple, but depending on where it’s spread, it can become more difficult and expensive!
How to Clean Mold From Windows
In many cases, mold around windows doesn’t become a major problem and home owners can remove it using a mild detergent before scrubbing and wiping the windows clean. You can also mix just a cap full of bleach in with a gallon of warm water and use that on a clean rag to scrub the window and any affected areas.
When you clean and remove mold from windows, don’t take any risks and make sure that you wear protective gear to prevent any mold from coming into contact with your skin. Wear rubber gloves and face mask while you’re cleaning too. As you finish, open the window or run exhaust fans for ventilation.
Black mold on Window Sill
Black mold can develop on a window sill if moisture builds up. This can be caused by humid weather, a leaky roof or condensation buildup. If untreated, the mold can spread and start to damage the sill and surrounding area in addition to potentially releasing unhealthy particles into the air.
It is important to take action quickly if mold is spotted – this means dry up any sources of moisture and then use disinfectants such as bleach or vinegar for cleaning and prevention. Taking care of black mold in its early stages can prevent problems from getting worse down the line.
Removing Mold From Window Frames
When you’re removing mold from your window frames, make sure you know what type of frame they are. Removing mold from aluminum window frames is easy, just soak them in a bleach solution for a few minutes and then wipe it clean.
Wooden window frames are significantly more difficult because bleach is corrosive to wood. Plus, mold is more likely to grow deeply into wood and be more difficult to completely eradicate without replacing your window frames. It’s worth trying to remove mold from your wood windows using vinegar, but you may have to replace the window frames.
Prevent Mold From Coming Back To Your Windows
To prevent a recurrence however, you need to include weekly window dusting as part of the regular housekeeping routine. Reducing the humidity levels inside your home with a humidifier and moving indoor plants out can also help.
What if Mold Has Spread to the Dry Wall or Sheetrock?
