Mold Removal Service for Dry WallA common question surrounding mold in households is “how fast can mold grow?”

We all know Mold can be detrimental to our health. It grows behind walls, in ceiling spaces, under carpets and below floor boards, typically growing unnoticed and without restraint. Unfortunately, most molds grow at temperatures that humans prefer, making our home the perfect place for them to thrive.

So how fast is mold growing?

Mold grows fast. Mold can grow within 24 hours. So, mold removal in Toronto, Vaughan, Ottawa, Mississauga, Vancouver, Edmonton, Brampton, and Montreal is needed fast.

 

What will determine the speed of mold growth?

  • Air flow
  • Humidity
  • Temperature (usually above 3 deg. C)
  • What organic material is actually wet  (e.g. mold grows faster on dry wall than wood)

If mold is clearly visible then it is growing and will reproduce by releasing it's spores that will settle in surrounding areas if allowed to aerate. Under perfect conditions mold colonies can grow at 1sq inch per day and cover surface areas of several square feet in less than a week.
 

Other common questions: can mold grow in the wintertime? If I can’t see mold, does it still grow?

Mold can grow safely in our refrigerator at temperatures below 4 deg. C, we’ve all witnessed this before. So the assumption that mold doesn’t grow in the winter time is certainly untrue. It is agreed in the wider scientific community that common household mold will not grow outdoors at -15 deg. C though temperatures rarely drop below 5 deg. C in the home, even in the coldest and darkest of basements.
