Let’s keep this one short and sweet. There really is no reason to over think or over complicate this. If drafty windows had you feeling the chill last Winter, use the temperate days of Fall to make your Winter indoor season more comfortable.
The solution to this problem is very simple! All you need is a quick trip to your local hardware store to buy some caulking. Here is why it’s important to get this chore done while the weather is still somewhat warm.
Caulking sets better when it’s dry and temperatures are not freezing. So don’t leave this one till it’s too late, apply it before it’s too cold, otherwise it won’t stick properly. Oh, and don’t forget to weather-seal around doors too.
For windows that open, use weather stripping to seal the movable parts. If you want to get some fresh air in on a nice Winter day, be sure the seal stops air leakage but still lets the window operate freely.
