Dark spots in the corner of the room, behind the wardrobe or on the window: Mold appears particularly frequently during the heating season. The reason is almost always the same. Warm indoor air meets cold walls, moisture condenses, and provides the ideal breeding ground for mold.
Typical causes
- Insufficient or incorrect ventilation, for example, windows left permanently open
- Cold exterior walls and corners where humidity condenses
- Furniture placed directly against an exterior wall
- Laundry drying in the apartment
Removing mold: step by step
- Protection: Wear gloves and ventilate the room thoroughly. Never wipe mold off dry, otherwise the spores will spread.
- Treat: Apply a mold remover to the affected area and leave it to work according to the instructions.
- Wipe off: Wipe up the residue with a cloth and then dispose of it.
- Let dry: The area must dry out completely before you continue working.
- Repaint: An anti-mold paint helps keep the area permanently clean.
Use mold remover carefully. Always read the label and product information before use.
How to prevent it
- Ventilate thoroughly for a few minutes several times a day instead of leaving windows open
- Heat rooms evenly, even those that are rarely used
- Place furniture a short distance away from exterior walls
- Keep an eye on the humidity with a hygrometer
When a professional company is needed
Small areas can be easily treated yourself. In the case of large areas, recurring infestation, or damp masonry, a professional company should clarify the cause.
