A yearly inspection of the windows in your home can insure that the weather stripping has not been damaged and is functioning properly. We all know how hard the wind can blow in our Southeastern MN winters. Cold air can enter through even the smallest of gaps. Repair damaged weathers tripping or seal small gaps with a quality silicone sealant. On draftier windows you may choose to seal them with shrink wrap film to help save on energy usage.
Drafts can be located on windy days by slowly moving a lit candle or butane lighter near the window. An air leak will cause the flame to flutter and help you to locate leaks that need to be sealed. Make sure all flammable materials are out of the way so that you don’t accidently start a fire.
