Posted by AlorAir Alex on

Mold is defined as the microscopic fungi that grow in the form of multicellular structures and have a thread-like appearance. It mostly grows in damp places where it often forms patches and of different colors be it black, brown, greyish, white, or green.

A musty smell is an indication of the growth of mold in your home even when you don’t see any visible growth. When left unattended, mold contributes to poor indoor air quality.

The growth of mold requires the presence of moisture.  The moisture could be coming from daily activities such as cooking, washing, air humidifiers, leaks, flooding, or condensation. Poor ventilation also contributes to high levels of moisture in the air, leading to the growth of mold.

 It is important to be able to spot mold, recognize the potential health effects, and come up with ways of tackling it without wasting time.

In many cases, mold growth becomes so rampant that it becomes so difficult for homeowners to control and eliminate it properly by themselves. This forces them to look for professional mold removing companies to do it for them.

In addition to destroying one's property, mold also has adverse effects on the health of people living in mold-infested homes. This is the reason why it is very important to identify and eliminate it as soon as it starts to develop.

Mold is highly toxic and has life-threatening effects on humans depending on the species and exposure conditions. Old people, pregnant women, and any other persons with weak immune systems are the most vulnerable when it comes to health effects caused by mold.
