We have many things to inspire us today!  I am here today to write about fresh air and flowing water.  Two things that embody Spring.  To the optimist it’s fantastic, sunshine on your face, wearing only 2 layers instead of 3 and new growth in nature and business!  To the pessimist we have flooding basements, allergies, muddy shoes/paws and it’s probably windy.

I think I can turn it around with some education on what to do about moisture intrusion and I will also write out the benefits on measuring the air within your home.

Moisture Intrusion leads to mold in our homes if it is not rectified.

I want to write about this dry topic (pun) because a lot of this water in the house business begins in the Spring!

Sprinklers near exterior walls!  Let’s not repeatedly spray our homes down with water.

Constant overspray from sprinklers can cause moisture to permeate through the walls of your home and when repeated over the Spring and Summer can end up in interior building materials. Drywall, baseboards, window frames and insulation can become elevated with moisture and potentially help support mold growth.

To prevent this from occurring, simply do not allow your sprinklers to overspray onto exterior walls. We recommend installing a drip-system in areas that are near exterior walls. If this is not an option, the next best thing is to ensure that the sprinklers are spraying away from the building.

Planter boxes on the exterior walls can have the same effect.  Make certain that the planter boxes are water proofed.

Structures built on a sloped hill can present challenge problems. Rain and other water runoff will move downhill where it may pool next to or come into contact with your home.  Have an appropriate landscape design that will redirect water away from your building. Ensure that appropriate drainage is installed around the exterior of the structure.


On the inside of the home:

The two main reasons for dampness are:

  • Moisture cannot escape
  • Water is getting in

Quite often, it’s your lifestyle that’s causing condensation and possibly mold to build up inside your home.

If you just have a mild bit of mold discolouring, you can easily get rid of it by simply wiping it down with a wet wipe or a damp cloth. If it’s a bit more obvious, you might need to wipe it down with a damp and mold spray. Watered-down bleach works great, or check out what products are available at your local hardware store.  I use moldcontrol spray if watered down bleach is not an option.


Getting rid of damp and mold in your house is something that you need to keep on top of and solve. Damp walls can affect your belongings and your health, and it’s just not nice living in a damp house. Since most problems can be solved with just a short amount of time, investigating, ventilating, and getting a dehumidifier now will pay off in the long run.

How are we going to investigate?  I recommend the Awair by Omni.  It is an indoor air quality testing system that I can leave in your home for  at least 3 days and the homeowner gets to quickly log their activity while the sensors in the unit log the following items:

Dust, VOC’s CO2, Temperature, Humidity.

I then log into the “Dashboard” and can access your report and we can investigate whether there are some items in your home that have higher readings.  Armed with information, we  can address the route cause and it can be fixed or items added to the home such as a dehumidifier, even an HRV.  If we cannot see the mold and you are wondering if it is in the indoor air, I can test that too by capturing an air sample with a bio-pump and submitting it to a lab for testing.
