Windows Sweat and Condensation - What Should You Do?

Discovering water droplets forming on your window panes isn’t uncommon, especially for Canadian enduring such harsh winter climates. The extreme low temperatures cool the glass, which in turn cools the air that comes into contact with it, creating condensation. The fogged glass caused by these water droplets looks unappealing, and can induce the formation of harmful moulds. Take care of sweating windows as soon as possible, to avoid an uncomfortable, unhealthy home.

Ventilation is Key

Poor ventilation in your home can make condensation worse, and the formation of mould escalate quicker. Opening your windows from time to time can help move stale air out, and bring fresh air into your home. However, in doing this you waste heat and money. If your windows have gaps or leaks, chances are they are providing a source of ventilation by allowing the free passage of air from outside to inside.It is wise to seal these leaks, and seek ventilation elsewhere, in order to retain heat in your home and save you money.

Heat recovery ventilation systems (HRVs) are a great condensation-combating solution in cold Canadian climates. They reduce moisture build up by transferring stale air out of your house, and bringing fresh air into your house. Furthermore, HRV stake the heat from the stale, indoor air, and transfers it to the fresh, outdoor air. This helps in regulating the temperatures in your home, keeping it warm and comfortable in the wintertime.

Dealing With Mould

Water droplets on your windows will fester along the edges, and could lead to the formation of harmful moulds. This is not only an unsightly mess, but also a prominent health risk for your family. Mould should be cleaned as soon as it is discovered, and measures should be taken to prevent its formation in the future. To avoid future outbreaks, take care of your mould problem with a fungicide, and keep your windows dry.

Dry windows and increased ventilation will keep window-sweat under control,and ensure a healthy home for you and your family.

We had our windows installed last summer and absolutely love them - especially the large kitchen window. Our sales rep Jim S. was terrific and knowledgeable. The installers did a professional, skilled job of installing our windows. And the windows themselves are high quality, easy to open and easy to clean - as well as reasonably priced. We are very happy with our entire experience with this company and highly recommend them. Thank you!

We had our windows and door installed by NorthShield, we are very satisfied. The sales man Jim was fantastic, he answered all our question and concerns and made sure we understand all what we were inquiring about. We are happy with the product and the price. The installation crew Anton Alex and Russ were amazing, they were polite, professional and very friendly.They explained and showed us how to operate our new windows and door and cleaned up after themselves even after we told them not to worry about the cleaning. We have recommended NorthShield to our friends and neighbours.
