How do you combat mold in a prefabricated house?

It stinks, is annoying and harmful: mold at the house. Everyone has probably "experienced" him before, but where does he come from? And above all: what can be done against mold in prefabricated houses? The following article provides answers to these questions and more information on the topic of mold.

How does mold develop in the house? But the most important source of moisture is man himself: in a four-person household, the human body alone produces 12 liters of water vapor per day. This should be handled correctly: Ventilation helps here, as the fresh air penetrates so quickly. Ineffective, however, are constantly tilted windows; they do not generate enough heat exchange and waste energy.

Is there a special danger in prefabricated houses?

Naturally, mold can spread more easily if the structure of the house is "leaky". In prefabricated houses, as they were built 50 years ago, there is of course a greater risk of mold than in today's solid houses due to the "light" construction.

However, the trend in prefabricated houses is becoming more and more massive, which is why the mold risk in modern prefabricated houses is just as low as in massive buildings.

Is there anything else to consider?

One of the most common reasons for mold proliferation is construction defects: so if you feel that mold is spreading, have your prefab house inspected for construction defects such as cracks.


The following overview summarizes the reasons for spreading the mold again:

Humidity too high

  • Structural defects
  • Incorrect ventilation
  • Heat dissipation in the basement
  • Tips & TricksUse a thermometer with humidity display; so you can avoid the spread of mold in advance and keep the critical 60% limit in mind.
