Basement mold is a type of fungi that grows on the walls of your basement due to moisture presence. Mold is usually invisible to the naked eye, but it appears as dark spots on your walls if it has been there for a while. 

Another sign of mold growth in your basement is the presence of a bad smell.

Mold is bad for many reasons. It causes health problems like asthma, allergies, and respiratory diseases, especially in children and the elderly. It also destroys the structural integrity of your building by causing damage to walls and ceilings, which can lead to a collapse if not taken care of for a long time.

What Causes Mold Growth in Your Basement

Some factors that cause mold growth in your basement are moisture/water, warm temperature, humidity, and lack of light. If you have a moldy basement, it is important to take steps to eradicate it before it spreads further. 

How to Go About Black Mold Removal

As mentioned above, mold grows in damp and dark areas of your home. This includes the basement, crawlspace, and even the attic. You can prevent it by cleaning up debris, fixing leaks, and using a dehumidifier. You can also open a window to keep the air moving.

If the area infested by mold is small, you can do black mold removal by yourself. You just need a pair of gloves, goggles, and an overall. Then using a mixture of hydrogen peroxide and water, scrub the infested area with a wire brush.

To prevent further mold growth in your basement, you can do the following:

1. Get rid of the source of the moisture/water. This includes cracks in walls, leaky plumbing/ broken pipe, faulty sump pump, etc. In other words, make sure your basement is waterproof. It is best to seek the help of a basement waterproofing expert to help you with this.

2. Make sure that you have adequate ventilation to help air out your basement. If you are unable to do this, consider purchasing a dehumidifier to help with the humidity.

3. Remove any debris, dirt, grime, or dust on the ground and ensure the floor is clean and dry.
