Dark spots in the corners, a musty smell, condensation on the windows — none of this is accidental. Mold and moisture always have a specific cause, and until that cause is addressed, any surface treatment is only a temporary fix. Here is what is actually going on.
In most Warsaw flats, excess moisture comes from one or more of the following sources:
Mold is a fungus. It needs humidity above 70% and a temperature between 5°C and 35°C — exactly what most flats offer throughout winter. Mold spores are always present in the air. The moment they land on a damp surface, they begin to grow. A colony can establish itself within 24 to 48 hours of a surface becoming wet.
The highest-risk spots: the bathroom (behind the bath, under the sink), kitchen (above the window, behind the fridge), bedroom (corners against external walls), and storage rooms or wardrobes without ventilation.
The mold on the wall is a symptom, not the problem itself. The real cause is somewhere deeper. Self-diagnosis can be misleading — the same stain can indicate a thermal bridge, a leak from above, or a damaged pipe. Getting the diagnosis wrong means wasted money on repairs, and the mold comes back.
If you are unsure what is causing the problem in your flat, send us a request through the contact form. We will come, assess the situation, and suggest a concrete solution. We work across Warsaw.
If the source of damp is a damaged water or drainage pipe, do not put off calling a professional. A leak inside a concealed pipe run can damage the building structure and cause problems for the flat below. The longer you wait, the more expensive the repair.
The cost of the work depends on the nature and scope of the problem — you can get an accurate quote through the contact form after an on-site assessment.
