What is mold?
Molds are microscopic fungi that are widespread in nature. They mainly belong to the groups of ascomycetes and zygomycetes and reproduce through spores that float in the air. As soon as they have found a suitable surface, they settle. Indoors, they often appear as colored stains on walls, ceilings or furniture. Mold can also appear on food that is not stored properly or has expired.
How does mold develop?
The main cause of mold growth indoors is moisture. This can be caused by various factors:
- Condensation:
When warm, moist air meets cold surfaces, condensation can form, which encourages mold. - Building defects:
Leaky roofs, cracks in the walls or a lack of thermal insulation can allow moisture into the building. - Inadequate ventilation:
Moisture from cooking, showering or drying laundry can accumulate if there is insufficient ventilation. - Water damage:
Leaks or flooding lead to increased moisture, which promotes mold growth.
Areas with high humidity such as bathrooms, kitchens and cellars are particularly at risk.
Why is mold dangerous?
Mold can cause serious health problems and poses a considerable risk, particularly to vulnerable groups.
- Allergies:
Mold spores in the air can trigger reactions such as sneezing, coughing, skin rashes or watery eyes. - Respiratory diseases:
Prolonged exposure to mold can promote chronic complaints such as dry cough or asthma, especially in people who are prone to these health problems. - Mycotoxins:
Some types of mold form toxic substances known as mycotoxins. These can be harmful if inhaled or in contact with skin, and may lead to headaches, tiredness, or difficulty concentrating.
Children, the elderly and people with a weakened immune system are especially at risk.
How can you combat mold?
When combating mold, it is important both to remove the visible infestation and to eliminate the causes:
- Small areas:
BIf discovered early, superficial mold on tiles, walls or window seals can be tackled with special mold removers or disinfectants such as our Hydroliq PROFESSIONAL. The great advantage of our disinfectant is that it kills both mold and bacteria and does not contain any harmful substances. Hydroliq PROFESSIONAL is therefore even suitable for sensitive areas such as children’s rooms or kitchens. Any remaining visible mold stains (remnants of the killed mold) can then be removed with conventional cleaning agents. - Larger infestations:
If mold has spread over a large area or has penetrated deep into walls and materials, a specialist should be called in. They can reliably identify the cause and carry out safe, sustainable remediation. - Safety measures:
To avoid contact with mold spores, protective gloves, breathing masks and suitable protective clothing should be worn when removing mold.
How can you prevent mold?
Prevention is the most effective way to avoid mould growth.
- Correct ventilation:
Regular airing helps to remove moist air and reduce humidity. - Heating:
A constant room temperature prevents walls from cooling down and thus the formation of condensation. - Furniture placement:
Furniture should not be placed directly against external walls to ensure air circulation. - Minimize sources of moisture:
If possible, do not dry laundry in living rooms and ensure adequate ventilation when cooking and showering. - Building and renovation measures:
In new buildings or renovations, attention should be paid to good thermal insulation and effective moisture protection.
Conclusion
Mold indoors is not just a visual problem, but a serious health and structural problem. Knowledge of the causes, especially moisture and inadequate ventilation, enables targeted prevention and early intervention. A conscious approach to indoor climate, structural substance and hygiene is crucial.
Whether in your own home or a rented apartment – effective mold prevention requires attention and targeted action in everyday life. If the infestation proves to be complex, professional remediation is essential to avoid lasting damage. If you are well informed and take action at an early stage, you not only protect the building fabric, but above all the health of all residents in the long term.
