Condensation on my windows

Q) I constantly have condensation on my windows. Why does this happen and how can I prevent it for happening?

A) Condensation on the inside of windows is the most noticeable sign that you have excessive humidity in your home. Some condensation is normal, however if you have constant foggy windows there could be a problem. There are ways to control the moisture in your home.

1- Use ventilation fans in kitchens, bathrooms and laundry rooms to keep the air circulating.
2- Squeegee your tub and shower after every use, also dry the area with a towel, leaving the fan on for at least one hour after use.
3- Open interior doors to increase air flow
4- If you have a dehumidistat switch, set it to the correct outside temperature setting:

Outside Air Temperature / Inside Humidity Setting

Home at 20C / 50%

0 to -12C / 40%

-12 to -18C / 35%

-19 to -24C / 25%

-25 to -30C / 20%

-31 or below / 15%
