Where Does Mold Grow the Most? 

Mold does like to grow in the wet spots of your home where leaking has occurred such as your pipes, roof, walls, or any place where there may be leak and excess moisture. It will also grow on the window sill and between the panes from condensation. Mold around the windows is a clear sign that the windows have lost their efficiency and functionality and therefore should be replaced. 

Condensation Within Panes 

Especially during the winter season, Condensation can become more present around the window area. The dry warm heat from inside interacts with the cold moist air coming from outside therefore causing condensation. This condensation can then cause mold if left unchecked.

If you see any, you will want to wipe it away and dry the area well. You can also use a dehumidifier in the room to help keep the air around the window dry. Taking these steps will help to prevent mold from growing in the first place. Make sure your exhaust fans are working and your family is using them when taking baths and showers as well as in the kitchen. Open windows and doors in your home to help to bring fresh air into your home. If your home has an air conditioner, make sure it is operating efficiently and the drip pan is clean and drain pipes are clear of debris.  

Leaving windows Open During the Winter Can Promote Mold Growth.  

One of the main causes of mold is moisture. When there is excess moisture in the air, it can condense on cold surfaces, such as windows. This can happen even if the temperature outside is not that cold. When this happens, it can create the perfect environment for mold to grow. Leaving your windows or doors open during the winter, when there is cold moist air in the home, can promote mold growth in your home.

Mold can cause a variety of health problems, especially in young children, the elderly, and those with respiratory problems. Mold can cause coughing and wheezing, as well as aggravate asthma symptoms. In some cases, mold can even cause serious infections. If you or a family member starts to experience any of these symptoms, you should see a doctor as soon as possible. 

Although, in general mold is not something that should be taken lightly, there are thousands of diverse types of molds that are found across the world.

The best thing to do is to monitor your home and clean the area where mold is present as soon as possible.
