The Importance of Properly Sealed Windows




This year on Groundhog Day, there was an abundance of snow, wind, and ice. And, because of said snow, wind, and ice, a good portion of people also experienced power outages. Fun, right?

For many, not so much. It’s amazing what can’t happen when there’s no power. Phones (cordless ones, anyway) don’t work; routers are rendered useless; kids get the ever coveted snow day. But then children can’t come indoors and have hot cocoa because there’s nothing to heat it up with. When there’s no power, there’s also no heat in the house. For homes that are well insulated, that’s not all that big of a problem.

But, what about homes that aren’t well insulated and/or have older, drafty, windows and doors in their midst? What then?

When was the last time your windows were checked?

It’s estimated that roughly 20% of a home’s energy loss occurs because of improperly sealed windows – windows that allow warm (or cool) air to be exchanged with the outside.


That means heating and cooling costs are 20% more than what they could be – over time, that seriously adds up.

But, how does a homeowner know if they’re one of the households that suffers from improperly sealed windows? Well, one of the easiest things to do is feel for a draft. Run a hand around the inside frame of each window – if there is a cool spot (assuming it’s winter) then it’s certain there is a leak. Another surefire way to know that windows are leaking is the presence of moisture. If there is moisture buildup around the windowsill or on the glass pane(s), then there is a spot where cold air and warm air are colliding.

“It’s estimated that roughly 20% of a home’s energy loss occurs because of improperly sealed windows.”

So, the next question is, what to do if drafts are noticed? Well, there are a couple of options. Adding weather stripping to windows is one of the fastest and easiest ways to stop leaks. When properly applied (which is sometimes where well-intentioned DIY-er’s slip up), the unwanted exchange of air can be stopped. Installing storm windows – which create an additional barrier against wind and moisture – are another option, but they’re something that need to be put in prior to the onslaught of nasty weather.

A more permanent solution would be replacement windows. Granted, this is the more expensive option (up front), but it IS one that will seriously pay off in the long run via a reduction in heating and cooling costs. And, of course, a great way to help hold the heat in a bit longer should the weather turn frightful, making your time without electricity a bit more delightful.
