Black Dust In The Attic

Black mold in attics.

Black dust in the attic.

The black attic mold shown here confirms that this attic had a serious venting and moisture problem including moisture from sources lower in the building. It was all over the roof sheeting and laying in th insulation near a clothes dryer vent stubbed into the attic the pictures arent that great but i am just looking for opinions thanks in advance. I was wondering if any one could guess what the black soot like substance could be in an attic i inspected. Clean out your ductwork if it s confirmed that you have mold growing inside.

Dark dust is blowing into your home. Try trimming the wicks so they don t burn to high and produce black smoke. Spray the moldy area with the mold removal spray and scrub with a rag or light brush. In the winter when the air is drier it s doesn t take much for plastic surfaces to attract fine particles like soot.

I would suspect it s your candles since you aren t burning any fossile fuels. Such is this dust that within 5 minutes when the drum is only a 1 4 full the filter gets clogged by this very fine dust and all suction becomes useless. Dirt and dust stains are gray but if they are present long enough or in high enough concentrations they can be near black in color. I d bet it s black as well.

Check your tv screen too. Your home s ductwork is located in unconditioned spaces like attics and behind walls where all kinds of dust and dirty insulation abounds. Soot is generally black. If the register is closed the air is forced along the ceiling and the next thing you know you ll start to see black buildup across your ceiling.

This happens due to trapped damp air often in the late fall or early winter. Repeat the process until you are successful in removing all traces of it. Many other molds are green or grey but black mold tends to be a dark greenish black or gray color. Confirm that the black particles are actually mold spores through a lab test.

It beats guessing what the source of the stain is. When this humid relatively warm air cannot escape the attic space before the temperature drops condensation can occur. You can typically identify black mold by its color. A lab analysis of the stain is a nice but expensive luxury.

Most of the time dirt accumulates on ceilings because air is leaking in from the attic between the drywall and the supply register. In order to remove black dust or mold firstly switch off the heating cooling vents. It will appear around the home as a slimy dark greenish black or gray substance. If your clients can afford it great.
