Cleaning homes with persistent unpleasant odours in Lyon

Identify the Origin of Bad Smells

The first step towards eliminating bad odours in a dwelling is to identify their origin. Sources can be varied and often hidden, making the challenge all the more complex.

Potential sources of Odeurs

• Plumbing problems: Obstructed pipes can produce bad odours through sinks or toilets.
• Moisture problems: Excessive moisture leads to mould formation, releasing unpleasant odours.
• Household waste: Remains of food or unexcluded garbage bags can cause nausea very quickly.
• Infiltration of external odours: Smells of smoke or cooking from neighbours can invade your space.

Professional cleaning techniques

Professional cleaning does not just mask odours, but is intended to eliminate them at source to ensure a healthy environment.

Use of Specialized Detergents

Specialists use enzyme detergents that break down molecules that cause bad odours. These products are particularly effective on organic surfaces such as wood or fabric.

Brumization techniques

The mist consists of spreading a fine mist of disinfectant into the air, which attaches itself to odour particles to neutralize them. It is a method frequently used in cleaning up Critical housing in Lyon.
