Dark growth on drywall or around a leak? Get it identified and removed properly - without panic, and without spreading spores through the house.
Stachybotrys chartarum is the species behind the headlines - a dark, slimy mold that needs material to stay wet for a week or more, which is why it usually marks a leak nobody caught: a slow drip inside a wall, an AC pan that overflowed all summer, storm water that soaked a slab and never dried. Plenty of dark mold is not Stachybotrys, and plenty of harmless-looking mold is worth removing. Identification is a lab question, and removal is a containment question either way.
Bleach lightens the stain on non-porous surfaces but does not kill roots in drywall or wood - the growth returns, sometimes in weeks. Dry-scraping or ripping out molded drywall without containment aerosolizes spores into the whole house. The safe sequence is boring and effective: contain, HEPA-filter the air, remove, treat, dry, verify.
Because black mold almost always means sustained moisture, jobs tend to involve containment and material removal: typically $1,500-$5,000 for a contained single area, more where growth has spread through wall cavities. Written scope before anything opens up.
