What Causes Mold in a Home?

what causes mold in a home

Mold is a living organism known as fungi. Mold grows in dark areas and basically consumes the material to which it attaches. Wherever it appears, this fungi naturally assists with the decay process. There are a number of things that can cause mold to grow in the typical home.

Conditions that Cause Mold to Grow in a Home

Here are the common conditions that encourage mold growth.

Moisture

One of the most important things mold needs to grow is moisture. Moisture doesn’t have to be excessive, but it must be present. It can be in small amounts like humidity or it can be in large amounts like a big water leak. It can most commonly occur in a basement, bathroom, or kitchen. Any consistently damp area in a home is a place where mold can easily appear.

Darkness

Mold cannot grow in ultraviolet light which means it won’t grow in sunlit rooms. This is why mold grows well in basements or in dark cupboards or closets.

It can also grow behind paneling, drywall and underneath carpeting. Any place in the home that is constantly dark is a natural breeding ground for this fungi.

Food

Since mold is a living organism, it requires food to grow. Household materials like cotton, wood, and drywall can easily become targets of mold growth. These function as “food” for mold and are one of main reasons why mold grows so easily in homes built from these common materials.

Time

Mold doesn’t grow in minutes; it takes time to form, which is why you must clean up water spills right away. Mold usually takes between 24 to 48 hours to be appear, but that’s only if the conditions are right for it to grow.

Mold can take longer to grow if the proper conditions evolve more slowly. That’s why it’s so easy to miss mold growth in areas of the home until the fungi has done a lot of damage or caused health problems.

Temperature

Temperature is another factor that must be right or mold won’t grow. It doesn’t grow well in the winter in locations that are generally cold. Warmer climates and warm areas of the home provide the right climate for mold growth, especially when damp.

How to Prevent Mold in Your Home

The best way to prevent mold in your home is to continually make sure your home is free from excessive moisture by keeping the humidity level down (can use a dehumidifier and ventilation to control moisture) and to clean up any spills or leaks immediately.

It’s a good idea to provide proper maintenance in your house regularly because mold can cause illnesses and damage to your home in a short period of time.
