Mould Testing Services in Markham

Mould (Mold) is everywhere — it is in the air we breathe and grows on virtually any surface. In fact, there are thousands of species of mould in Canada. Mould grows when an organic substance comes in contact with water and can then spread throughout a home or office. This is why we offer mould testing in Markham.


Environments where moulds thrive are extremely unhygienic and downright dangerous for humans. The concern here is that moulds are capable of entering your home through windows, air conditioning systems and vents. In fact, shoes, clothing, bags and even pets can bring in mould from outside.

The earliest signs of mould can be inferred from cracked paint in your walls that’s peeling off. It is important for you to pay serious heed to such signs and call in professionals to check it out. The really bad aspect of invisible mould growth is that they may be growing behind your walls in gaps with moist air. Don’t underestimate this as even a small mould buildup visible on your wall could actually mean that there is a rather large colony on the other side.


Prolonged exposure to high levels of toxic airborne mould spores, such as Aspergillus or Stachybotrys chartarum (“Black Mould”), can cause chronic or even life-threatening illnesses such as:

  • Respiratory problems
  • Skin inflammation
  • Hemorrhage
  • Irritation of the mucous membranes
  • Damage to internal organs
  • Mental impairment
  • Tiredness
  • Nausea
  • Immune system suppression


Fisher Labs provides accurate analysis and data interpretation for various species of toxic moulds, which are known to cause health problems. The various projects we handle everyday are a testament to that!
