What Is Black Mold?

  • Stachybotrys Chartarum is the type of mold often called "black mold" or "toxic mold."
  • Sensational news reports warn about the dangers of black mold, and these stories can be alarming and confusing.
  • Any mold in your home should be treated with caution — stay out of affected areas and don't touch or disturb the mold.

How Do I Tell If It's Black Mold?

Since many types of mold can produce allergens and irritants, you should contact us regardless of the color or type of mold. In many instances, multiple types of mold can exist in the same house or structure.

Understanding the Mold Remediation Process

Step 1: Contact Us

The mold cleanup and restoration process begins by contacting us. We will ask a series of questions to help us determine the necessary equipment and resources.

Step 2: Inspection and Mold Damage Assessment

We will carefully inspect your property for visible signs of mold. Mold feeds on cellulose and water and can be hidden from plain view.

Step 3: Mold Containment

We use various containment procedures to prevent the spread of mold. All fans and heating and cooling systems will be turned off to prevent the spread of mold.

Step 4: Air Filtration

Our specialized filtration equipment allows us to capture microscopic mold spores out of the air. We utilize powerful "air scrubbers" and HEPA vacuums to prevent the spread of these mold spores while mold remediation is in process.

Step 5: Removing Mold and Mold-Infested Materials

The mold remediation process depends on the amount of mold growth and the types of surfaces on which the mold appears. We use antifungal and antimicrobial treatments to eliminate mold colonies and to help prevent new colonies from forming.

Step 6: Cleaning Contents and Belongings

We clean your furniture, decorative items, curtains, clothing, and other restorable items affected by mold.

Step 7: Restoration

Depending on the level of mold damage, drywall, subfloors, and other building materials may be removed and may involve minor repairs.

Mold Remediation

Any home or business can quickly become infested with mold with the introduction of a water source, like a roof or plumbing leak. Mold can spread throughout a property in as little as 48-72 hours and can produce allergens and irritants that have the potential to cause other health effects.


If you suspect that your home or business has a mold problem, we can inspect and assess your property. If mold is found, we have the training, equipment, and expertise to handle the situation.

Understanding Mold

Microscopic mold spores exist almost everywhere, outdoors and indoors, making it impossible to remove all mold from a home or business. Some restoration businesses advertise "mold removal" and even guarantee to remove all mold, which is a fallacy.

Consider the Following Mold Facts:

  • Mold is present almost everywhere, indoors and outdoors.
  • Mold spores are microscopic and float along in the air. They may enter your home through windows, doors, or AC/heating systems or even hitch a ride indoors on your clothing or on a pet.
  • Mold spores thrive on moisture. Mold spores can quickly grow into colonies when exposed to water.
  • Before mold remediation can begin, any sources of water or moisture must be addressed. Otherwise, the mold may return.
  • Mold often produces a strong, musty odor and can lead you to possible mold problem areas.
  • Even higher-than-normal indoor humidity can support mold growth. Keep indoor humidity below 45 percent.
