The scourge of humidity often manifests itself in our homes, stealthily nesting around windows and glass doors, especially during the winter chill. This unwelcome intrusion is none other than black mold, an unwelcome guest that invites itself despite our best efforts. But what can be done to thwart the path of these harmful spores? In this article, we unveil the origins of this phenomenon and share tips to combat it during the winter season!

The challenge of mold around windows

Finding mold at home is far from rare, especially in humid rooms like bathrooms when temperatures drop. Single-glazed windows, more vulnerable to moisture accumulation and fungal proliferation, are not the only ones affected; even double-glazed windows can be afflicted by these unaesthetic black marks.

Indeed, while the presence of mold is not always alarming, it can become a health hazard, especially for individuals with asthma, eczema, or respiratory disorders.

As the U.S. Environmental Protection Agency emphasizes, 'Mold can trigger asthma episodes in sensitive asthmatic individuals.' Similarly, 'Asthmatic individuals should avoid any contact with mold.'

Prevention Strategies

Use of ventilation systems

Opening windows wide in cold weather is hardly feasible, even though it promotes ventilation. Fortunately, modern window ventilation devices provide sufficient airflow to limit mold proliferation. It is advisable to keep them open to ensure optimal ventilation.

Relocating indoor plants

While indoor plants beautify our living space and purify the air, their proximity to windows can exacerbate ambient humidity. It is recommended to move them away from windows during the winter.

Use of a dehumidifier

To combat humidity, especially in kitchens and bathrooms, the use of a dehumidifier is an effective solution. It is wise to pair it with extraction fans to minimize moisture.

Eradicating existing mold

To eliminate mold already present on windows, a simple solution of white vinegar works wonders!

How to proceed?

Before starting, protect yourself with gloves to avoid skin irritation.

  • Generously spray vinegar on the stains.
  • Let it sit for an hour.
  • Then, clean with a brush and warm water.
  • All that's left is to wipe and dry with a clean, dry cloth.

Special attention to wooden frames

Unlike UPVC frames, wooden frames, due to their porosity, are more susceptible to mold. Wood retains moisture and promotes mold growth. A preventive solution would be to paint or stain these wooden frames and ensure their joints are clean and dry.

By applying these tips, the threat of black mold around windows can be effectively repelled, preserving the health and aesthetics of our interiors.
