In addition to dirt buildup, dirty windows can cause mold around windows. Mold can become a serious problem and even lead to health problems.

The following blog will discuss how black mold around windows is formed, as well as advice on how to properly and safely remove mold from your windows. Also, included are tips on how to prevent mold growth. If mold continues to appear, it might be time for replacement windows.

How Mold Around Windows Is Formed

Mold is a living organism, a type of fungi that breeds in areas that are dark and damp. It can also grow in areas in the home that are prone to high levels of humidity and do not have proper ventilation. Black mold in the home, as well as black mold around windows, can be a very serious issue.

Black mold is very hazardous, as it contains mycotoxins. These toxins can cause damage to the central nervous system and in serious cases, even be fatal. Mold in any form can worsen breathing issues and allergies. Symptoms from exposure to mold include wheezing or asthmatic attacks, itchy and watery eyes, skin conditions, such as eczema and psoriasis, brain fog, and chronic fatigue.

Mold usually forms in rooms that are prone to high levels of moisture in the air, such as kitchens, basements, and bathrooms. Mold can grow on walls, carpets, and even on furniture. Mold around windows can also form in these conditions. 

Why Mold Around Windows Is Problematic

As previously stated, mold grows in areas that are prone to high levels of humidity. As windows are prone to moisture due to weather conditions and other factors, mold can easily form on windows. Condensation forms on windows when cold air clashes with warm air. If window condensation is not removed, it can lead to mold growth.

Mold around windows can spread to the foundation of your window frame. This can lead to serious problems with the foundation of your home as well as such issues as bug and rodent infestation.

Getting rid of mold and preventing regrowth is essential to a healthy living environment. Continue reading to find out how to properly treat and prevent mold growth from recurring. 

How to Clean Mold Around Windows

Do no bleach to clean mold, as it only covers it and does not kill the growth. Also, do not forget to wear long sleeves and pants, gloves, safety goggles, a face mask, and a hair net to prevent mold exposure.

Keep children and pets away from the area. Open windows to allow for ventilation. Tape up air vents to prevent airborne mold taxis from infesting your home.

Mix warm water with baking soda and liquid dish soap. Using a clean sponge or cloth, clear the areas of mold growth with this mixture. Immediately, dispose of the used sponge or cloth in the trash. 

Mix water and cleaning vinegar in a spray bottle and spritz on the surface to kill any remaining mold spores. Let this sit for half an hour and wash it away with warm water. Let it dry completely. 

Dispose of all cleaning products and wash clothes with hot water straight away.

How to Prevent Mold Around Windows

  • Do not overwater indoor plants. If possible, contain them in one room only. 
  • Open windows and doors whenever possible. Use fans, exhaust fans, and dehumidifiers in those rooms that are prone to excessive humidity.
  • Do not leave wet towels sitting around. Moreover, do not air-dry laundry.
  • Fix any plumbing or gas appliances as soon as you spot an issue. This can prevent excess moisture in the air.
