Contact a professional mould restoration expert if you suspect toxic mould is present in your home. 

Contact a professional mould restoration expert if you suspect toxic mould is present in your home. 

It can lurk in your fridge, on walls, ceilings, and windows. It's unpleasant looking and causes most of us to grab our rubber gloves and bleach to scrub it away. However, it can also create a health risk when inhaled or absorbed. We’re talking about mould.

We’re here to help answer all your questions about mould and why in extreme cases, it's essential to contact a mould restoration company to handle the cleanup and also manage mould growth through water restoration services.

What is mould?

Made up of microscopic fungi, mould spreads via tiny spores that release into the air. These fungi can attach to both organic and non-organic materials such as drywall, metal, and concrete, but only if there is a nutrient source, such as moisture or dirt, feeding it.

Where does mould grow?

Mould loves warm and wet conditions and tends to grow in humid areas of a residence, such as a bathroom or a kitchen. Mould can also grow in unventilated areas and where there is a build-up of moisture from a leak or flood. Some of the most common places where mould grows include:

  • Shower and bathtub
  • Sinks and toilets
  • Walls and floors
  • Refrigerator and pantry
  • Windows and windowsills
  • Indoor plants
  • Pillows and mattresses
  • Attic insulation

What are some of the most common mould types found in a home?

There are more than 100,000 species of mould. The most common household mould types include:

  • Alternaria: A category of allergenic moulds that grow in dampness, characterized as having a velvet texture with dark brown or green hairs.
  • Aspergillus: Another allergenic mould found where there is a high concentration of sugar, salt, or starch (such as bread) and in environments rich in oxygen. Aspergillus mould typically produce spores that are black on the surface and white or yellow underneath.
  • Cladosporium: A mould species that produces a dark-pigment, usually green or black, commonly found on indoor plants.

What are some of the health signs of mould exposure?

Some strains of mould produce mycotoxins that can cause health problems. The most common is black mould (Stachybotrys chartarum), a species of aspergillus that grows in extreme moisture and can cause serious illness in humans and animals.

Some of the signs of mould exposure include:

  • Headaches
  • Aches and pains
  • Respiratory difficulty
  • Nosebleeds
  • Allergic reactions
  • Infections

How do I prevent mould growth in my home?

Removing moisture from your home is one of the best ways to prevent mould growth. Monitor humidity by equipping your home with a dehumidifier and increase air flow through ventilation and fans. Install sump pumps in crawl spaces and basements, repair leaky roofs, and attend to flood damage cleanup immediately. Apply mould resistant paints and drywall products to walls and windowsills. Make sure to call a mould restoration company if you experience extreme cases of mould or water damage.
