What Is Black Mold?
Black mold, scientifically known as Stachybotrys chartarum, is a greenish-black fungus that thrives on materials with high cellulose content—such as drywall, paper, and fiberboard—that have been chronically wet.
Unlike other common house molds, black mold is toxigenic, meaning it can produce mycotoxins. These toxins are released into the air via spores and can be inhaled or absorbed through the skin, leading to potential health concerns for residents.
Because it thrives in damp conditions, black mold is often found in areas with long-term water damage, high humidity, or poor ventilation that prevents surfaces from drying properly.
Health Risks of Black Mold
- Respiratory Issues. Inhaling spores can cause coughing, wheezing, and shortness of breath in healthy individuals.
- Allergy Flare-ups. Congestion, skin irritation, and red or itchy eyes are common reactions to mycotoxins.
- Asthma Urgency. Mold exposure is a known trigger for frequent and more severe asthma attacks.
- Sinus Problems. Chronic sinus infections or persistent head pressure often coincide with mold presence.
Where We Find Black Mold
- Basements & Foundations. Behind baseboards or under flooring after foundation leaks or sump pump failures.
- Leaking Drywall. Behind walls near leaking pipes or windows where water has saturated the paper backing.
- Attic Sheathing. On the underside of roof decks where poor ventilation causes condensation in winter.
- Bathroom Enclosures. Under vanities or behind tiles if grout has failed or exhaust fans are non-functional.
Our Black Mold Removal Process
- Inspection: Visual assessment and moisture mapping to determine the extent of the growth.
- Containment: Setting up poly-barriers and negative air pressure to stop spore spread.
- Removal: Safe removal of saturated materials and antimicrobial scrubbing of salvageable surfaces.
- HEPA Cleaning: Air filtration and vacuuming with HEPA filters to capture microscopic spores.
- Verification: Final inspection to ensure the area is clean, dry, and safe for occupancy.
Why You Shouldn't DIY Black Mold
Attempting to clean black mold without containment often makes the problem worse. Scrubbing or disturbing dry mold releases millions of spores into your air, causing them to settle in other rooms and HVAC systems. Professional remediation ensures these spores are captured and removed from your environment permanently.

Black Mold FAQ
How do I know if it's "Black Mold"?
While only testing can definitively identify the strain, toxic black mold is usually very dark greenish-black and has a slimy or wet appearance if the moisture source is still active.
Is all black-colored mold toxic?
No. Many common molds appear black but are not toxigenic. However, any mold indicates a moisture problem that should be addressed regardless of the strain.
Can I just use bleach to kill it?
Bleach is generally ineffective on porous materials like drywall. It kills the surface mold but the roots remain, and the water in bleach can actually provide moisture for regrowth.
How much does black mold removal cost?
Remediation costs depend on the area size and required containment. We provide firm written pricing after a physical assessment of the site.
