What Is Black Mold?
“Black mold” is a common term people use for dark-colored mold growth. It may refer to Stachybotrys chartarum, a greenish-black mold that can grow on materials like drywall, paper, and fiberboard when there is ongoing moisture or water damage. Not all dark mold is Stachybotrys, and mold usually cannot be identified by color alone.
Whether the mold is black, green, or another color, the most important step is to clean it up safely and fix the moisture problem. Professionals may use containment, HEPA filtration, protective equipment, and careful cleanup methods to help reduce the chance of mold spreading during the job. EPA says the key to mold control is moisture control.

Inspection
Professionals inspect the affected area, identify moisture sources, and assess how far the mold has spread. Addressing the moisture problem is essential to help prevent mold from returning.
Containment
Depending on the size and severity of the job, professionals may isolate the work area with containment barriers and use negative air pressure or HEPA-filtered air scrubbers to help limit the spread of dust and spores. EPA remediation guidance recommends containment practices based on the size of the affected area.
Removal and Cleanup
Mold is cleaned from affected surfaces, and heavily contaminated porous materials may need to be removed and discarded. The focus is on safe cleanup and correcting the source of moisture.
HEPA Cleanup
HEPA vacuuming and detailed cleaning may be used to remove settled dust and mold particles from the work area.
Final Review
The area is checked to confirm cleanup is complete and the moisture source has been addressed. In some situations, sampling may be used to help evaluate whether an area has been adequately cleaned, but it is not required for every job. EPA says that in most cases, if visible mold growth is present, sampling is unnecessary.
Frequently Asked Questions
Is black mold dangerous?
Any visible mold growth should be taken seriously, regardless of color. Mold exposure can irritate the eyes, nose, throat, skin, and lungs, especially in people with allergies, asthma, or weakened immune systems. CDC/NIOSH says molds that produce mycotoxins, including Stachybotrys chartarum, should generally be considered the same as other molds that can grow indoors.
How much does black mold removal cost?
Costs vary based on the size of the affected area, where the mold is located, how much material must be removed, and the repairs needed to fix the moisture source.
Can I remove black mold myself?
Small mold areas may sometimes be cleaned by homeowners, but larger areas, hidden mold, or mold caused by significant water damage are better handled by experienced professionals. EPA says that if the moldy area is less than about 10 square feet, in most cases you can handle the job yourself.
How do I know if it is black mold?
You usually cannot identify mold species just by looking at it. If visible mold is present, the priority is cleanup and moisture control. Testing may be useful in some cases, especially to help evaluate whether an area has been adequately cleaned.
