Did you know that the average home loses upwards of 30% of its heating and cooling energy through air leaks? If the windows and doors around your home are drafty, you’re contributing to this statistic. Read below to find out how quick and easy it is to save a few bucks on heating costs this winter by sealing cracks and gaps around your house.
How to Check for Leaks
First things first, you’ll want to check for air leaks. To do so, hold either a lit stick of incense or a lit candle near window and door frames. If you see the smoke or the flame blowing around, chances are you have a draft. If you don’t notice anything out of the ordinary, you can move on to the next one.
How to Repair Cracks and Gaps (Windows)
Weatherstripping tends to get the job done, but it does take some time to install.
Self-stick plastic is much easier to install, but the downside is it doesn’t last very long.
EPDM rubber is relatively inexpensive, is rather simple to install and can last 10 years or more.
How to Repair Cracks and Gaps (Doors)
Replace old weatherstripping with foam tape or felt. You can reinforce them by stapling or gluing in place.
For a better seal, you may want to consider tubular rubber, vinyl or silicone weatherstripping. Although they’re a bit more difficult to install, they provide an unparalleled seal.
If you notice air coming through underneath the door, check the threshold gasket and replace if worn. Additionally, you can attach a door sweep or use a snake to keep cool breezes out.
