Water is the #1 enemy of your home. It is caused by leaks and condensation, which is when warm moist air meets a cold surface. Water and frost on the windows is a visible example of condensation. Moisture may also collect in the attic and inside the exterior walls and controlling moisture in your home is the best way to prevent mould. Mould could damage the house structure, your possessions and/or your health.

Causes of moisture coming into your home could be from one or many sources. Ventilating your house with warm outdoor air, evaporation from showers, washing dishes and clothes, cooking, aquariums, inappropriate use of humidifiers, earth floor basements, inadequate heat to parts of the house, high swings in temperature, poor air circulation, poor quality windows, poorly maintained air conditioner, poor grading around the house, poor insulation and a cool basement could all result in a moisture problem. What to look for if you suspect a moisture problem could be present in your home: damp floors, white powdery stains on concrete, stains on carpet, condensation on windows, rotting window sills, damp smell, mould on joists and stored items, dripping cold water pipes, or peeling paint or wallpaper.

  • Your home should have an exchange of air between the outside and the inside via open windows or a Heat Recovery Ventilator
  • Remove known moisture sources and discontinue the use of humidifiers
  • Use a Dehumidifier in warmer seasons in your basement (May - Oct in Canada)
  • Use a hygrometer (relative humidity sensor) to measure humidity in your home keeping it below 50%
  • Provide sufficient heat to all areas of the house and promote good air circulation by running furnace fan continuously
  • Use exhaust fans in the kitchen and bathrooms when showering, bathing and cooking to remove the high concentration of moisture in the air at those times
  • Upgrade or seal your existing windows if needed
  • Open drapes and blinds in all windows daily
  • Caulk basement floors to the wall joint
  • Keep grading of your property sloping away from your home to ensure puddling at foundation does not occur (will get into basement over time).
  • Have a professional do a Comprehensive Air Quality Inspection, which includes the use of a moisture meter to find potential water behind walls, in insulation, etc.



  • Harmful chemicals can be released from synthetic fibers and household products when damp
  • Moisture supports the growth of mould and fungi which can pollute the air and cause odours and allergies
  • Can cause increased respiratory infections
  • Irritation to eyes nose and throat
