Is wood mold dangerous?
Yes, wood mold can cause allergic reactions to some people. Although mold may not be dangerous in itself, it may produce various toxins that fill the air. It is rare to come across an aggressively toxic wood mold. Wood mold may appear as a discolored layer on the wood. In high concentrations, the spores produced will fill the air in your home and cause allergic reactions to sensitive people.
Exposure to wood molds may cause symptoms such as:
- Sore throat
- Watery eyes
Wood mold may grow behind specific structures in your home and penetrate the air through air vents. The concentration of mold in your air will cause adverse respiratory diseases such as tuberculosis and fungus lung inflammation.
What does black mold look like on wood?
Detecting black mold on wood may be somewhat tricky due to the wood pattern and patches. Identifying the right color of the wood will help you look for a darker shade on the wood surface. Black mold may grow on either side of the wood before spreading to other parts in circular patterns. Black mold will flourish under damp or moist areas before expanding to much larger areas. Thus, when looking for black mold, check for areas with a high concentration of moisture and dark greenish colors spreading to other areas. Another way to identify black mold on wood is through the pungent odor that comes from the mold.
When inspecting for black mold in your home, ensure that you cover your nose, eyes, hands, and mouth covered. It is because of the natural toxins contained in the black mold that may cause adverse respiratory problems.
Causes of black mold growth
In order for mold to grow on any surface, but especially wood, moisture must be present. In homes and other buildings, moisture build up can be caused by many different things. If you have a large household, you have a better chance of finding the black fungus; when we breath we give off moisture. Additionally, hot showers and even cooking can contribute to the moisture-level in homes. However, moisture build-up can also occur from certain malfunctions in your home. Black mold can show up after you’ve had a leaky roof or pipes as any moisture that is trapped can turn into black mold.
Poor placement of fans
Poor placement of fans can be another factor that leads to black mold growth. Often, kitchen, dryer and bathroom vents may be opening up into an area of your house instead of outside. This allows damp to build up inside of your house which can lead to black mold growth. One of the most common causes of black mould growths in homes is poor ventilation. Additionally, a large variety of building materials actually provide the perfect nutrients to aid black mold growth, which would explain why black mold on wood is extremely common.
What kills mold on wood?
When fungi grow on wood, its roots remain deeply attached into the wood fiber even after scrapping the outer, visible surface. However, these following 5 steps should help you kill the black mold on your wooden floors, furnishings and surfaces.
- Step 1: Select a cleaning solution
You want a solution that will penetrate the surface of the wood and remove or kill the fungi. Regular cleaning detergent, distilled vinegar, bleach, rubbing alcohol and a good commercial fungi removal product may do the trick. Be sure not to combine the bleach with any product that contains ammonia. It could blow into some toxic fumes that could kill you or cause deadly infections.
- Step 2: Put on protective gear
Depending on the concentration of the cleaning solution you choose, you might want to put on some protective gear such as rubber gloves, a respirator, safety goggles, and coveralls, if available.
- Step 3: Scrub affected site with the cleaning solution
Using a clean low-abrasive brush or scrub pad, you will apply the cleaning solution to the area affected with black mold. Scrub the area gently in circular motion until you remove the black color. Move to other areas and repeat the process until you remove the fungi from the wood’s surface entirely.
- Step 4: Sand the area
As earlier mentioned, mold roots can be deeply engraved in the wooden material. To prevent re-growth, your goal is to remove all the fungi roots. Here’s where the sanding process comes in. After sanding the area lightly, repeat the step above where you scrub with the cleaning solution to ensure the plucked roots and spore residues wash away.
- Step 5: Let it dry
After you remove and kill the black fungi, collect any residue or items that have come into contact with the fungi and discard them. Clean the area with new and uncontaminated items to prevent spreading the fungi again. Let it dry by placing it in a nicely ventilated and dry area. Give it all the time it needs to look and feel dry.

Another method of removing black mold from wood is to use a High Efficiency Particle Air (HEPA) vacuum. These vacuums can be used after the above steps. A HEPA vacuum is good to use in order to make sure that all mould particles have been removed. This can include dust they may have accidentally been spread during your initial cleanup of the black mold. Be advised that if you have fungus in a carpet or mattress, it can be extremely hard, if not impossible to get rid of. In those cases, it may be best to dispose of the contaminated objects.
