Mold in the apartment: what to do?

7 minutes. for reading

Indoor mold is a microscopic fungus that can grow on various surfaces such as walls, ceilings, furniture, as well as on food and damp areas of the room. Mold forms in conditions of high humidity, lack of good ventilation and the presence of organic materials that can serve as a food source for it.

Mold can come in a variety of colors, including black, white, green, or orange. It reproduces through spores, which can spread into the air and settle in other places. The presence of mold in an apartment can not only create an unpleasant appearance, but also cause health problems, especially for people with allergies or asthma.

Mold control includes eliminating the source of moisture, regularly ventilating the room, cleaning and disinfecting surfaces, and, if necessary, using specialized products to kill fungi. Preventive measures, such as maintaining optimal humidity levels and carrying out timely repairs, will help prevent the formation of mold in residential areas.

Where does mold come from?

Mold in an apartment is formed from fungal spores that are present in the environment. The mold formation process involves several steps and depends on several factors such as humidity, organic materials and temperature. Here is a detailed explanation of where mold comes from in an apartment:

  • Fungal spores in the air: Fungal spores are everywhere in the air. They are microscopically small and light, which allows them to spread easily in the air. These spores are part of the natural microflora of the environment.

  • Humidity: One of the key factors for mold growth is high humidity. When indoor air becomes too humid, it creates favorable conditions for fungal growth. Damp surfaces, especially if they contain organic matter (eg wood, wallpaper, drywall), can be an ideal place for mold to form.
  • Organic materials: Mold uses organic materials as a food source. This can be wood, wallpaper, carpets, food, books, clothing and other organic matter. When moisture is present and conditions are right, mold begins to multiply and form microscopic fungal structures.
  • Temperature: Mold typically grows in warm temperatures. A warm and humid climate creates optimal conditions for active growth and reproduction of fungi.

Thus, mold can appear in an apartment when there is a combination of high humidity, the presence of organic materials and the right temperature. Regular ventilation, humidity control and timely cleaning will help prevent the formation of mold in your living space.

Where is mold most likely to form in an apartment?

Mold most often forms in those areas of the apartment where certain conditions are observed that promote its growth. Here are some of the typical places where mold most often forms in an apartment:

  • Bathroom: High humidity in the bathroom, especially after a shower or bath, creates favorable conditions for mold to grow. Corners, tile joints, shower curtains and ceiling corners are places where mold often forms.
  • Kitchen: Mold can appear in the kitchen due to high humidity associated with cooking, dishwashers and washing machines. Mold can also grow in sink areas, areas under kitchen furniture, and inside cabinets, especially if the humidity is not controlled.
  • Rooms with poor ventilation: If there is not good air circulation in a room, the humidity can rise, making it an ideal breeding ground for mold to grow. This applies to bedrooms, living rooms and other rooms.
  • Dark areas: Mold prefers dark places where organic materials combined with moisture create optimal conditions for its growth. This could be the backs of furniture, corners, closed cabinets, etc.

  • Insufficient insulation of walls and windows: Poorly insulated areas can be susceptible to condensation, leading to increased humidity and subsequent mold growth.

Regular ventilation, maintaining normal humidity levels, fixing leaks and repairing areas with damaged finishes can help prevent mold from forming in your home.

Why is mold in an apartment dangerous for humans?

Mold in an apartment poses a danger to humans for the following reasons:

  1. Allergens: Mold spores and their metabolites can be strong allergens, causing allergic reactions in people. Symptoms may include cough, runny nose, itching, rash, and even more severe allergies.
  2. Asthma and breathing problems: Long-term exposure to mold can worsen existing breathing problems and trigger asthma in people susceptible to the condition.
  3. Organ selectivity: Mold toxins can affect a variety of organs, including the respiratory, nervous and immune systems, which can affect your overall health.
  4. Skin problems: Contact with mold can cause skin irritation and allergic rashes.
  5. Toxic substances: Some types of mold produce toxins (mycotoxins) that can be harmful to health. These toxins can become airborne and inhaled, leading to a variety of problems, including liver disease and other organ disorders.
  6. Infectious diseases: In rare cases, mold can cause infections, especially in people with weakened immune systems.

To prevent these problems, it is important to maintain cleanliness, monitor humidity levels, provide regular ventilation, and promptly eliminate mold sources in your home. If extensive mold growth is detected, especially if it is accompanied by poor health, it is recommended that you contact a professional mold removal service and have the area disinfected.

How to deal with mold in an apartment

Fighting mold in an apartment requires an integrated approach. Here are a few steps to help you deal with this problematic phenomenon:

  1. Eliminating the source of moisture:
    • Regular ventilation: Ensure good air circulation in the room. Ventilate your apartment regularly, especially wet areas such as the bathroom and kitchen.
    • Leak repair: Fix all roof, pipe, window and door leaks to prevent moisture penetration.
    • Humidity control: Use humidifiers and air conditioners to maintain optimal indoor humidity levels (usually 30% to 50%).
  2. Cleaning and disinfection:
    • Regular cleaning: Clean and maintain cleanliness in all areas. This includes regularly cleaning walls, windows, floors and other surfaces.
    • Use of antimicrobial agents: Use special cleaning products that destroy mold and its spores.
  3. Use of moisture absorbents:
    • Silica gel or other absorbents: Place moisture absorbents in areas with high humidity to prevent condensation on surfaces.
  4. Use of antimicrobial and anti-mold agents:
    • Special preparations: Use special antimicrobial paints, varnishes or wallpaper to prevent mold from appearing on the walls.
  5. Use of natural resources:
    • Vinegar: Mix vinegar with water and treat moldy areas.
    • Cleaning properties of garlic: Place chopped garlic heads in areas with high humidity.
  6. Professional disinfection:
    • Contact the specialists: For extensive and complex mold cases, it is recommended that you contact a professional mold remediation service. Experts will conduct a detailed assessment, eliminate the sources, and suggest appropriate measures.

It is important to regularly monitor the condition of your home and take preventive measures to prevent the appearance and development of mold.
