Mold Q&A: Understanding Mold In Your Home


How does mold enter a home?

Molds usually enter homes when spores float through open doorways, ventilation, windows, or heating and air conditioning systems that have outdoor air intakes. Additionally, mold spores can also attach themselves to humans, animals, shoes, clothing, bags and other objects.

How does mold grow?

When spores reach a place of moisture, especially those places where there is excessive moisture, they will begin to grow. The most common places where molds grow are roofs, pipes, walls and plant pipes.

What are health problems associated with mold?

Mold exposure may cause cold-like symptoms, such as watery eyes, sore throat, wheezing and dizziness. Allergic reactions to mold are very common. It can irritate the eyes, skin, nose, throat, lungs, and even trigger asthma attacks!

Some molds are toxic! Prolonged exposure can be hazardous to humans.

What surfaces can mold grow?

Really, any surface is susceptible to mold growth if moisture is present. Moisture seeping through concrete, wood, plastics and other materials, can cause dampness resulting in molds on walls, floors, carpeting and more. The bathroom is the most susceptible place for mold growth because it is often damp. Soap scum, shower walls, ceramic tile and fiberglass are all common surfaces for mold growth. Basement and laundry rooms are also ideal for mold growth, if not dry.
