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.


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.
