Black Mold: An Introduction to Prevention and Identification

Mold is one of the most common household and workplace issues that people face. It can be found anywhere, from your basement to your kitchen cabinet. The dark color of mold makes it difficult to see unless you know what you are looking for. This blog post will discuss dangerous black mold: where it comes from, how to prevent it, and how to identify it if you find any in your home or office building.

What Is Black Mold?

“Black Mold” or stachybotrys is a specific type of toxic fungus that can appear in damp areas of your house. It is characterized by its unique appearance, as it is darker than most types of mold. Contrary to popular belief, “Black Mold” isn’t any more toxic than other molds. All molds are biohazards that can produce toxins and should be removed immediately when found.

Black Mold can originate from many different sources. It thrives in damp areas with a lot of cellulose, such as cardboard or paper items. Black mold is also present in some foods that are high in cellulose and low acidity (e.g., nuts).

However, mold can grow in any warm, wet areas of the house such as basements, showers, crawlspaces, and especially on windows. It can form as the result of your ventilation not working properly or if you have leaky pipes.

If you suspect you have leaky pipes in your house, you should check your basement thoroughly for mold. You should also check showers, corners, and crawlspaces if you think your ventilation is not working properly.

If left unchecked it will cause serious damage to your home.

How Do I Know if My House has a Moisture Problem?

One of the best ways to tell is by checking the humidity. A home with high humidity likely has a moisture problem. Musty smells suggest mold, mildew or rot. Household odors that linger may indicate too much moisture in the air. Frost and ice on cold surfaces from condensation can be a sign of excess moisture in the air as well.

Signs of a Black Mold Infestation

It is difficult to see and identify black mold. The first clue that it may be present in your home comes from the symptoms of exposure, such as nasal congestion or coughing.

If you can physically see the mold in your home, in most cases it’s bad enough that you probably need to call a professional mold removal team.

How to get Rid of Black Mold and Removal Tips

If your mold infestation is mild, there are a few things you can do to help get rid of it. When using a mold removal substance, make sure to test on a small area of your surface first to avoid ruining the material.

Wear Protective Equipment

If you’re going to remove mold on your own, make sure you wear Personal Protective Equipment, or PPE. Mold spores are dangerous and can cause or aggrivate many different respiratory issues. If you already have a respiratory illnes such as severe allergies, asthma, or COPD, avoid doing this yourself.

Scrub With Bleach

A mixture of bleach and water scrubbed on the moldy surfaces will kill the mold spores and disinfect them. If the mold hasn’t begun to destroy anything and it’s just on the surface, this is a great way to remove the mold. Let the mixture kill the mold, then scrub the surface.

Use about a capfull of bleach in one gallon of water.

Clean with Vinegar

White vinegar mixture can also kill mold. While bleach needs to be diluted, white vinegar usually doesn’t. Or at least not to the same degree. Half and half should work well. Or you can spray the vinegar directly on the surface. Let the mixture kill the mold, then scrub the surface.

Specific Mold Removal Products

You can use mold removal products in the same way. Follow the instructions on the packaging and the mold should come off easily.

Call a Professional

If removing the mold yourself is ineffective, it may have penetrated deeper into your home than you realize. Call a professional mold removal team like Jenkins Environmental Services to make sure that all of the mold is removed and your house is safe!

Preventing Future Black Mold Infestations

To prevent mold from returning in the future, identify potential sources of moisture within your home’s walls and how they can be eliminated. Also make sure to address any existing structural issues such as leaky pipes or cracks in foundation that allow humidity and moisture into your home.
