How does mold get into a house? Causes and Prevention.

Mold is a non-scientific term for several kinds of unwanted fungus found both outside and within,. Moisture attracts active mold growth. Actively-growing mold affects the substrate on which it resides, thereby impairing structural integrity. In addition, mold, including allergies and infections, is associated with certain untoward health effects in humans.

Spores can enter through:

Through the air: Open windows, doors, and ventilation systems are available.

By adding to items or persons: Clothes, shoes, and pets are included in vehicles.

Mold only thrives if spores land, such as moisture, and the availability of suitable nutrients, somewhere which has the perfect growing conditions. If the atmosphere is unsafe for spores, they typically do not grow or cause problems.

Places where mold occurs commonly include:

– Areas where there have been leaks and flooding

– Windows that accumulate condensation

– Places where for example, behind a locker the air does not circulate

Mold growth is supported mainly by wet cellulose materials.

For example:

– Wallpaper contained paper goods

– Plateau

– Tiles of ceiling

– Wooden goods

– Materials of isolation

– Polishing and other textiles

The development of mold is generally noticeable and sometimes creates a musty smell. It can harm household goods and can affect health as well.

Mold and health:

In particular, for people with an allergy, an underlying respiratory condition, or a compromised immune system, mold can pose a health problem.

Problems with breathing:

Spores, cells, fragments, and unstable organic compounds may enter the air as mold grows. Allergens, irritants, and mycotoxins may be produced by them. Some of these can be harmful especially to people who are sensitive to them.

Dampness also allows materials to break down, increasing the number of airborne particles or dust.

These particles, particularly in a person who already has a breathing problem, asthma, or chronic lung disease, may irritate the lungs, nose, and throat.


An individual with a sensitivity or allergy to any particles related to mold can react.

Mold allergies may cause other allergies, such as hay fever or seasonal allergies, to have similar symptoms. Airborne contaminants can also impact the upper respiratory tract in these cases.

Includes symptoms:

– A runny or blocked nose

– Itchy nose

– Dry throat

– Sneezing 

– Watery eyes 

When there is mold in the area, individuals with a mold allergy as well as asthma have a greater risk of experiencing an asthma attack.

Higher dust volumes can increase the risk of dust mites, which in some people may also cause an allergic reaction.

Other Conditions:

The formation of microbes and bacteria can also be activated by mold. According to the World Health Organization (WHO), exposure to these bacteria can cause an inflammatory response in some individuals.

The WHO also states that the risk of bronchial and fungal infections can be increased by mold and the microbial agents it creates.

There is some proof that it may lead to:

– Pneumonitis with hypersensitivity

– Bronchitis Infection

– Allergic Alveolitis Invasion

– Chronic Rhinosinusitis in patients

– Fungal allergic sinusitis

– Problems with the lower respiratory tract of previously stable children

Prevention & Protection:

People can decrease the risk of moisture and mold accumulation by:

– Acting immediately if there is a leak or spillage

– To decrease indoor moisture, use a dehumidifier 

– If possible, leave the windows open to allow air to circulate.

– To remove moisture during cooking, use extractor fans 

– Avoiding moisture-generating indoor activities, such as drying clothes or using kerosene heaters

– Ensuring that all fabrics are fully dry until they are stored

– From time to time, drawers and closets are seldom used for emptying and airing

– Cleaning frequently so that mold does not build up on surfaces, dust, or other substances

– When cleaning the toilet, the use of mold-killing items

– Preventing the laying of carpets in toilets and basements

– To reduce the risk of leakage, the maintenance of houses, utilities, gutters, and drains
