Mold – What Is It and Where Does It Occur?

Mold is a common problem in both old and new houses. It develops in damp areas – such as bathrooms – and often spreads on tiles, grout, and window frames. Mold particularly appears around bathtubs or showers when moist air condenses on cold surfaces.

Where Does Mold Come From?

Mold spores are constantly present in the air and do not necessarily require condensation to settle. Nevertheless, mold particularly occurs where condensation forms – for example, due to insufficient ventilation or on cold wall surfaces in winter. The spores are undemanding and can easily spread in living spaces.

A mold test kit helps to analyze the contamination and take the right measures.

What Does Mold Look Like and What Damage Does It Cause?

Mold is often harmless at first, but with severe proliferation, it can become a health risk, especially for children and sensitive individuals. Mold fungi need constant moisture to spread.

How to Identify Mold in Living Spaces?

Mold often becomes visible as small black or brown spots on wallpaper, in grout, on walls, or windows. Depending on the type, greenish or bluish discolorations may also occur.

Why Does Mold Occur in Old or New Buildings?

Mold frequently appears in renovated old buildings or new constructions – often caused by insufficient ventilation, incorrect heating behavior, or structural defects. Recognizing the causes is crucial for targeted action.

How Can I Test for Mold Myself?

With the mold test kit from airself, you receive 6 culture media for air analysis, detailed instructions, and an evaluation sheet. The analysis indicates whether the contamination is low, average, slightly elevated, high, or very high – for up to six rooms.
