The most common sources of house mold

Harmful indoor Mold sources

Mold is often the unseen enemy within our homes. Craftily, it finds an ideal nook that it calls home, and from there it can gradually grow and expand its reach. And because it comes up on us unknown, if left unchecked, Mold can lead to deadly consequences, not just for the structure but its inhabitants too. Chronically ill family members, young children, the elderly and infirm, and even the family pets, are not spared from the effects of Mold.

Read on to learn more about some common sources of house Mold.

The perfect Mold home  

Mold is very particular about where it resides. Homeowners won’t find it on a windowsill that’s bright with sunlight. Nor will you see it on floors and tiles that you walk on daily and vacuum and mop daily. However, even if most of the home is airy, filled with natural and artificial light, and cleaned often, there are sources inside your home that can allow Mold to flourish:

Indoor Humidity Levels

Climates that are extremely humid can lead to indoor humidity levels rising. On the other extreme, homeowners living with low indoor humidity levels tend to power up their humidifiers to seek relief. Other sources of indoor humidity include:

  • Improper usage of exhausts after showering
  • Cooking in a sparsely ventilated kitchen
  • Drying clothes on lines strung up indoors

Mold needs indoor humidity levels to be slightly higher than 55% to take root. So whether you use a humidifier or a de-humidifier, make sure the humidity levels inside your home never surpass the 55% level.

Indoor Condensation

Condensation is a prime source of indoor Mold. Where floors and walls are exposed to high degree of cold – example thin externally facing walls, or basement floors – turning the temperature higher indoors can produce condensation on those surfaces. Even cold pipes and ducts can start condensation when they meet with warm indoor air.

While carpeting (on floors) or insulating (on pipes) can give some protection against condensation, homeowners must still be vigilant for signs of dampness in such areas of the home.

Indoor leaks

Leaking roofs, pipes and appliances (washing machines, dish washers, water heaters) are another source of house Mold. Hidden pipes (behind walls and floors) and damp attics can sometimes host Mold for many years, allowing it to spread throughout the home, before the telltale signs (discoloration, damp patches, and odour) of Mold begin to appear.

The Mold Theme  

By now, readers may have twigged on to the fact that the common sources of Mold explored above have a recurring theme: Dampness. That’s right! Anywhere there’s unchecked dampness within the house, Mold finds a home. And the best way to protect yourself is to continually inspect and observe every part of the home, especially rarely used or lightly trafficked areas.

Routine spring cleaning, and periodic maintenance of homes is a great way to prevent these common sources of house Mold from destroying your home and your family’s health. ‘
