The Facts:

  • Mold might be the cause behind an unpleasant, musty odor in your home.
  • Mold has been shown to cause serious damage and bad stains on materials like wood and drywall, as well as other substances too.
  • Mold can be harmful when breathed in, so it's best to avoid it as much as possible.

What is Mold:

Mold is part of a family of fungi that thrive in damp, warm environments like your basement. It needs water to grow, sunlight or artificial light, cellulose (e.g wood), and other carbon-based sources like mold spores. Mold is able to travel through the air and infiltrate your attic via roof vents, large crevices, and openings such as an attic entrance and drop-down stairs.

The reason for this is because mold is a type of fungus that reproduces by making spores that release into the air.

Breathing in mold can cause all sorts of health problems. Over time it may lead to allergy issues and respiratory troubles, in addition to the damage they cause. The problem is most prominent in attics, where mold can grow freely.

Not only does moisture contribute to the growth of mold, but it also causes rot. Mold can grow anywhere and can be particularly hard to get rid of. When the mold is there for too long, not only will it cause damage but can also affect people's health.

Ventilation Errors

Oftentimes, during home renovations, vents are not properly managed which makes the air go back inside. For example, a bathroom fan keeps air from blowing into the attic or a dryer vent waste duct directs dirty humid air indoors.

The vent is blowing warm, moist air into the attic - which is causing mold infestation on the wood. This should be stopped so that the air can blow outside instead.

Warm Moisture and Cold Attics mean disaster

Mold grows easier in colder climates than it does in warmer climates. But the same circumstances exist that allow mold to grow anywhere, even in milder temperatures. To find out how mold infestation begins, let’s look at a couple of common mistakes below.

Venting your bathroom exhausts warm & humid air to the attic, making sure it never gets to the outside. That means even when it's cold, bathroom showers won't create a drafty situation in your attic.

When air is heated up it will rise to a region that is cooler. The cold sheathing the attic provides will cause water droplets to form and turn into water.

The water dripping from the roof is wetting the sheathing and creating droplets that drip down the planks as a sponge to absorb any water. This is why wet wood can be found in a dark, humid environment such as old buildings where mold loves to grow.

Mold can also be a sign of Energy Inefficiency

Bad air quality in the workplace is caused by many things, not only mold. It may even be a sign of too much air entering your home via the attic. This means that your air conditioning system will work less efficiently, which could lead to exhaustion and other health problems.

Adjusting your insulation and getting rid of air leaks can prevent moisture and mold in your home. Areas to look for inefficiencies include gaps around recessed lighting, heating vents, and attic hatches or doors.
