How is mold checked in wet rooms?

Mold problems in wet areas such as bathrooms and saunas can cause serious health problems and structural damage. That’s why it’s important to regularly check wet rooms for mold. This article discusses how to check for mold in wet rooms and what steps can be taken to detect and remove mold.

1. Visual inspection

The first step in checking for mold is a visual inspection. This means checking all wet room surfaces, such as walls, floors, ceilings and seams, for possible mold growth. Mold can appear in different colors, such as black, green, brown or white. Pay special attention to the following points:

  • Tile joints and silicone joints
  • Environment of sinks and showers
  • Ceiling panels and wall panels
  • Ventilation valves and their environment

2. Odor

Mold often has a recognizable musty smell. If there is a constant unpleasant smell in wet rooms, it can be a sign of a mold problem. The smell can be particularly strong when the space has been closed for a long time, such as after a sauna.

3. Humidity measurements

A moisture meter is a useful tool for checking for mold. A moisture meter can be used to measure the moisture content of walls, floors and other surfaces. High moisture content may indicate that there is moisture damage in the area, which can lead to mold growth. Humidity measurements should be done especially in the following places:

  • Tile joints
  • Around showers and bathtubs
  • Areas below the sinks
  • Environment of ventilation valves

4. Surface samples

If visual inspection and moisture measurements indicate a mold problem, surface samples can be taken for laboratory tests. Surface samples are usually taken with tape or a cotton swab and sent to the laboratory for analysis. Laboratory tests can confirm the presence of mold and help identify the type of mold.

5. Professional help

If you suspect a mold problem, but you are not sure how to proceed, you should contact a professional. Companies that specialize in mold inspection and removal can perform a thorough inspection and recommend appropriate measures to remove the mold. Professionals can also use advanced equipment such as thermal cameras and hygrometers to obtain more accurate results.

6. Prevention

Prevention of home problems is important. Make sure wet areas are well ventilated and that moisture can evaporate quickly. Use high-quality construction materials and make sure that all seams and joints are tight. Regular cleaning and maintenance also help keep mold at bay.
