Mold on the floor - what can you do?


Mold marks on the parquet certainly cause the most breathless horror. What is the most common cause of mold on the floor, how to correctly assess the damage, and what is possible to remove everything, you will learn in this post.

Mold recognized on the floor

Stains and discoloration on the parquet do not always mean the same mold. Parquet, especially solid wood, can get spots (mostly black or blackish spots) for many reasons. One possible reason would be, for example, a patchy blackening of oak parquet, when the tannic acid contained in it gets in contact with certain metals. This can happen even with oiled parquet.

Typical mold marks

Typical of mold is always a typical smell. This can usually be seen as a layman, whether it is mold or a different discoloration of the wood. In a green or other colored, musty smell, however, one can assume that it is mold.

Typical smells:

  • musty
  • moldy
  • earthy or after forest floor
  • rare: slightly pungent, while still musty

Superficial mold

It often happens that mold spreads to the parquet floor when something moldy or damp comes to rest on the parquet floor. That the mold is only superficial, you can tell by the fact that you can easily wipe it off.

Corrugated wooden edges

Due to the moisture, parquet wood underneath, especially at the edges, may be slightly wavy. This is because mold needs moist environments, and therefore moisture was involved. However, if the parquet floors are deformed very severely, it must be assumed that the moisture may have come from below the parquet. In this case, a thorough examination by a specialist mold expert is essential to detect potentially hidden infestations.

Special case bamboo parquet

Bamboo parquet is - unlike other types of wood - very sensitive to long-term moisture. Here, in many cases, even if it is coming from above mold - the parquet is usually beyond saving, and the point in question must be replaced.

Mold under the parquet

The case that mold has formed below the parquet is fortunately very rare. In the majority of cases mold comes from above onto the parquet and remains superficial for a long time until it slowly eats into the wood.

Determine mold under the parquet

If one nevertheless suspects that there is mold underneath the parquet, only a specialist expert examination can provide information (air measurement, possibly taking a small part, below a piece of furniture, and measuring below).

Remove superficial mold stains from the parquet

Instead of chemical mildew cleaners, which could eventually discolour the parquet, you should rather resort to home remedies, such as alcohol or alcohol, to disinfect and then wipe away the stain. If the mold is already drawn into the wood, usually only helps to grind the relevant spot.

Tips & Tricks

Hydrogen peroxide can also have a bleaching effect - so use it with extreme caution when applying it to the parquet floor and first test it in an inconspicuous place.
