How do you remove black mold?

Black mold can cause health problems, especially for people with allergies, asthma, or weakened immune systems - coughing, congestion, eye and throat irritation, and worse for the sensitive. No mold indoors is desirable, and color alone does not identify the species. Any significant growth should be removed by containment and remediation, not disturbed. More on this

Not on the surfaces that matter most. Bleach is made for hard, non-porous surfaces. On porous materials such as drywall, wood, and insulation it does not reach the root structure, so the mold grows back. The U.S. EPA does not recommend bleach as a routine mold-remediation tool. More on this

Most mold remediation takes 1 to 5 days. A small, contained area can be done in a day; a room-level job usually runs 2 to 3 days including containment, removal, and clearance; and extensive jobs involving multiple rooms, HVAC, or a crawl space can take a week or more. Drying and clearance testing add time. More on this

Mold removal is the physical act of taking out mold and contaminated materials. Mold remediation is the whole controlled process: inspection, containment, HEPA filtration, removal, surface treatment, fixing the moisture source, and verifying the space is dry and clean. Removal is one step inside remediation - and remediation is what keeps mold from coming back. More on this
