How to Permanently Eliminate Mold from Walls (and Why Bleach is Not Enough)

Living in humid areas, such as Venice and its surroundings, often leads to fighting a silent and stubborn enemy: mold. In addition to ruining the aesthetics of the walls, fungal spores pose a serious risk to the respiratory health of the whole family. Many believe they can solve the problem with a sponge and some bleach, but the reality is quite different.

""Bleach whitens mold making it invisible, but it doesn't kill its roots. The water contained in the product evaporates, feeding the fungus and causing it to reappear stronger than before.""

Do you have black spots in the corners or behind the closets? Don't just cover them with paint! pyBIM offers professional anti-mold cycles and ventilation solutions to definitively eliminate the problem at its root.

Mold is a living organism that thrives in enclosed, poorly ventilated environments with a high rate of humidity (condensation). Washing the wall with chlorine-based products gives the illusion of a clean wall, but it is a temporary and superficial remedy.

The Definitive 3-Step Solution

To eradicate the problem and prevent it from recurring next winter, a professional approach is necessary:

  • 1. Deep Remediation and Sanitization: We use specific professional biocides that penetrate the porosity of the plaster to neutralize fungal spores deep down, not just on the surface.
  • 2. Thermal Insulation Cycle: Once the wall is remediated, we apply special smoothing compounds and thermal (anti-condensation) paints. These products create a barrier that raises the surface temperature of the wall, preventing water vapor from condensing and forming the droplets that feed the mold.
  • 3. Humidity Control: The real cure is prevention. Often the problem stems from highly insulating windows that do not allow air circulation. In these cases, we design and install Controlled Mechanical Ventilation (CMV) systems, which exchange and purify the air while recovering heat, keeping indoor humidity always below danger levels.
