How Do You Identify Mold On Wood
Perhaps the scariest thing about black mold is that even with the significant hazards it poses, it is not easy to identify. For most people, the first sign that warns them of mold is the musty and earthy smell associated with mold. Mold generally prefers damp places and will typically start from the corner and spread out. If you can see discoloration on the wood surface, accompanied by the smell, that is usually a pretty good indicator of dealing with mold.
Dark spots and discolorations can also get confused with mold. These discolorations on wood can be due to natural wood staining, iron stains, sun exposure, and mineral discolorations. If you can see streaks leading from where you have fasteners in your wood, it is probably just iron stains, while greyed wood can be because of sun exposure. Discoloration on a moist piece of wood and the production of a musty smell is the best mold indicator.
If you are still having a problem confirming the presence of mold on wood, you can invest in a mold testing kit or call in a professional to look at it.
