Fall is here and so is mould season

Fall and winter can be very busy for mould.  Typically fall can be mould season.  Why?  There are a number of reasons homes can grow mould in the fall.

One of the main issues regarding mould in the fall is obvious…it’s rain.  Abundant rain can lead to leaky windows, leaky roofs as well as leaky basements.  All of these are a recipe for water penetration and mould growth.

Another issue, is condensation on windows and outer walls.  As the evening and night temperatures drop, so does the surface temperature of your home.  Any increase in humidity can cause condensation on these colder surfaces.  If this is sustained, mould can grow.  It is important to check your windows and window sill for any dampness or signs of mould growth as these are a sure sign of a growing mould problem.

Your furnace and furnace filter can also be a breeding ground for mould.  In the fall there can be an accumulation of dust and pollen from the summer months that can be food for mould growth should dampness or condensation occur in the HVAC system.

So what should you do in the Fall to prevent mould growth.

  1. Set your humidity lower.  Ideally below 40%
  2. Check to make sure your windows have a good seal to keep moisture out.
  3. Check your attic to make sure there are no leaks.
  4. Check the basement foundation walls to make sure there are no cracks or leaks.
  5. Replace the furnace filter and do a duct cleaning.
  6. Have a mould test performed to ensure mould has not already started.
  7. Make sure no condensation sits on window frames or window sills.
