Checking for mold under the floor is an important step that can help prevent health problems and structural damage. Mold can cause allergic reactions, respiratory symptoms and other health problems, so its detection and removal is of utmost importance. In this article, we go through how to check for mold under the floor and what measures are involved.

1. Preparations

Before you start checking for mold under the floor, it’s important to prepare carefully. The following steps will help ensure that the review is safe and efficient:

  • Protective equipment: Wear appropriate protective equipment, such as a respirator, protective gloves and safety glasses. Mold spores can be harmful if inhaled or in contact with the skin.
  • Tools: Make sure you have the necessary tools, such as a flashlight, hygrometer, screwdriver, and possibly an endoscope (a small camera that can be inserted into tight spaces).
  • Ventilation: Make sure that there is sufficient ventilation in the space so that mold spores do not spread to other parts of the apartment.

2. Opening the floor

The next step is to open the floor so you can check the space underneath. This may require removing floorboards or panels. Be careful not to damage the structures.

  1. Selecting a location: Select an area to check where you suspect mold may be present. This can be, for example, an area where there has been water damage or where moisture has been detected.
  2. Removing the floorboards: Use a screwdriver or other suitable tool to remove the floorboards. Be sure to remove the boards carefully so they can be reinstalled after checking.

3. Checking for mold

Once the floor is opened, you can start checking for mold. This step includes visual inspection, moisture measurement and possibly sampling.

  • Visual inspection: Use a flashlight to check the space below the floor. Look for signs of mold, such as black, green, or white spots, which could be mold growth.
  • Measuring moisture: Use a moisture meter to check if there is increased moisture under the floor. High humidity can be a sign of favorable conditions for mold growth.
  • Taking samples: If you suspect the presence of mold, you can take samples and send them to a laboratory for analysis. This can help confirm the presence and type of mold.

4. Actions to take after detecting mold

If you notice mold under the floor, it is important to take steps to remove it and fix the cause of the problem.

  1. Mould removal: Small mold growths can be removed by yourself using mold removers and protective equipment. Larger or more extensive mold problems may require the help of a professional.
  2. Moisture Control: Identify and correct the source of moisture that has caused mold growth. This can include, for example, fixing leaky pipes or improving ventilation.
  3. Next steps: Monitor the situation regularly to make sure the mold does not return. This may include taking moisture measurements and visual inspections.

Checking for mold under the floor is an important step that can help prevent health problems and structural damage. Careful preparation, careful inspection, and appropriate measures after mold detection are key to solving the problem.
