In Finland, a decade of constructing tightly sealed homes has raised alarms about them turning into 'mold bombs'. Building physics experts indicate that these types of buildings possess significant risk factors for moisture damage. Professor Paula Koski highlights specific architectural solutions that could be detrimental to the long-term health of these structures.

The report elaborates on two particular building practices that have been flagged as particularly problematic, potentially leading to conditions conducive to mold and other microbial damage. The prevalence of moisture issues in four out of five inspected homes underscores the seriousness of the situation, calling attention to a widespread potential crisis in the Finnish housing market.

As many homeowners became oblivious to these risks due to perceived advancements in building technology and standards, experts urge caution and recommend vigilance during property renovations. Insights from building inspectors further emphasize the necessity for thorough assessments in homes that have undergone amateur renovations, suggesting that past building codes did not adequately address the emerging risks associated with this new construction approach.
