“Is that black mold?” is what most people ask about a dark patch. The straight answer: the color doesn’t change what happens next. CDC says it isn’t necessary to identify the type of mold, because every kind should be handled the same way and removed. We remove dark mold, and every other color, in Slidell and eastern St. Tammany Parish. Call and tell us where you see it.
The species people mean, Stachybotrys, is greenish-black and grows on materials with a lot of cellulose — drywall, ceiling tile, paper facing, fiberboard — that stayed wet for a long time. It needs constant moisture. So a dark patch is more often a sign of a leak that ran for weeks than of a storm that came and went. Plenty of other common household molds are dark too. None of that changes the removal.
The same as any other mold: work area sealed and under negative pressure, wet porous material out and bagged before it leaves the room, framing cleaned in place, HEPA vacuum and wipe-down, and the wood dried before anything is rebuilt. Dark growth on drywall means that drywall comes out. On a ceiling, that section of ceiling comes out. We find where the water came in and tell you what has to change so it doesn’t return.
Dark growth here most often follows a roof that leaked through a whole season, a supply line inside a wall, or a house that took surge in 2005 and was closed up before the studs were dry. Houses with a dark line along the bottom of a wall years after Katrina are not unusual in Eden Isle or Olde Towne. If one room has never smelled right since, that’s the call.

A surge line along every wall, a roof that leaked through a whole season, or a house that sat shut and wet after Ida. Room-by-room containment and removal on one plan, one report.
Dark staining on the roof deck after a leak, a blown-off shingle, or a bath fan dumping into the attic. Cleaned in place with the attic sealed off from the rooms below.
The ceiling over the shower, the wall behind the toilet, the floor of the vanity cabinet. Small rooms that never dry, and removal that holds once the moisture is handled.
