Home Works - Condensation & Mould - Episode 1 of 2

Why does condensation appear on our windows in the winter? Along with my tips on how to clean up any mould around your windows.

Condensation & Mould

If you live in a home that was built within the last 20+ years you may have experienced condensation accumulating on your windows in the winter months. Beginning with the R-2000 standards back in the 1980’s, homes were built more air-tight and heavily insulated. Although this aided in keeping heating & cooling costs down, it did not allow warm, humid air inside the home to escape. By trapping this warmer air inside the home along with cold winter air contributed to condensation to occur on windows. This condensation then drips down and accumulates in the window sills and seams and when left unchecked begins a cycle of mould build-up.

There are a few ways to combat condensation with some inexpensive tricks and also with ventilation equipment which I will discuss in part 2 of this episode. For now, I am concentrating on cleaning up the mould along the window sills which I explain in this episode’s video.

Tips For Removing Mould From Window Sills & Seams

I use a few simple products & tools to clean up the black mould that tends to form along the bottom and corners of the windows:

  • Old Toothbrush
  • Putty Knife
  • All-Purpose Spray Cleaner
  • “Mold Control” Spray (found in most hardware stores)
  • Paper Towels or Shop Towels

The Process:

  1. Lightly spray the all-purpose cleaner along the areas where mould is present. (You may want to use an inexpensive dust mask if you have concerns about mould particles and/or chemical spray)
  2. Using the toothbrush, scour along the sills, seams, and corners to loosen the grime.
  3. Use the corner of a putty knife to get into grooves or corners.
  4. Wipe away with paper towels and dispose immediately.
  5. After the surface is dry, spray on the Mold Control product liberally and allow to dry overnight. Don’t worry if the product pools along the seams as it won’t be noticeable after it dries.
  6. Depending on how cold the winter is, and how much humidity and condensation you have in the home, you may have to repeat this process at least twice over the season. Mold Control is not a cure all but a temporary remedy that will last a good few months under normal conditions.

My next “Home Works” video blog episode will look into the techniques and equipment that can be used to control humidity levels in your home and eliminate condensation and mould.
