Mold can be found anywhere in the home, but crawl spaces are especially vulnerable because they’re not often inspected or cleaned.

What Causes Mold Infestation?

Mold infestation is a natural by-product of moisture. Moisture can come from many sources, such as water leaks or condensation. When the environment has enough moisture, mold spores will grow and thrive.

Mold can grow anywhere with moisture, organic material, and dark places. The most common areas where mold can grow are bathrooms, kitchens, basements, and closets. The moisture from these places will provide the perfect environment for mold growth if they are not properly cleaned up.

The most common cause of mold infestation is a leaky roof or some other water damage. However, it can also happen when you have an appliance leaking or standing water nearby.

What Is Black Mold?

Black mold is a type of fungus that can be found in damp, dark spaces worldwide. It is often called “toxic black mold” because it produces mycotoxins which are poisonous to humans and animals.

The most common types of black mold are:

  1. Stachybotrys chartarum
  2. Chaetomium globosum
  3. Aspergillus versicolor
  4. Cladosporium herbarum

In some cases, homeowners have had to pay for their expenses related to the damage caused by mold.

Can a House Full of Mold Be Saved?

If you’ve ever been to a house that has mold in it, you know how difficult it can be to get rid of the mold. If your entire home is full of mold, you should consider hiring an expert to help you with the problem.

How Long Does Mold Remediation Take?

Mold remediation can take anywhere from one day to four weeks, depending on the severity of the mold infestation and the type of material it is growing on.

This extensive range in time means that professionals or DIYers can do mold remediation with varying degrees of skill and expertise.

Can I Stay in the House During Remediation?

When a property is undergoing mold remediation, the occupants shouldn’t stay in their homes. However, there are some cases where people need to live in the house during remediation because they have no other option.

The mold remediation professionals will use various chemicals to kill the mold and other harmful agents. However, the chemicals can cause health problems like eye irritation, respiratory problems, and skin irritation.

If you are living in the house during this process, make sure to follow these precautions:

  • Wear a mask and gloves when cleaning up moldy material inside your home.
  • Don’t have any open windows or doors while cleaning up the house.
