How Does Cold Air Get Into My Home in the Winter?

Your heater runs and runs but your house is still cold. You can literally feel the drafts. This not only makes your heater work harder and increases the heating bill, but it also makes winter all the more miserable. There are several ways that cold air can make its way into your home. Let’s talk about them below and ways Service First Pros can help you keep your heating bill as affordable as possible.

Door Drafts

Your household doors are a common entry point for cold air. If the doors do not seal properly and are not weather-stripped, nothing will stop the outside air from coming through the small openings. It’s important to make sure that the door has protection all the way around it, including on the bottom. You can purchase weather strips at the hardware store to prevent cold air from seeping through your doors.

Window Drafts

The same thing can happen to your household windows. Older windows and window frames can warp and separate, creating a small gap between them and your exterior walls. This, naturally, will let air through. Single-paned windows do not protect from the outside air as well as dual-paned or insulated windows do. Single panes are not insulated and the cold air seeps through.

As with your doors, you can prevent cold air from entering your home by sealing the windows around their frames. It’s also a good idea to have any warped or damaged frames repaired. If you have single-paned windows and you cannot afford to install new ones, you can re-glaze the windows or purchase window coverings that are designed to keep the outside air outside.

Electrical Outlets

Cold air can also come through the electrical outlets. There are ways that you can block the cold air from coming through your outlets that are safe and won’t interfere with your household electricity. You can purchase foam outlet and light switch inserts that insulate the outlets to ensure they are not a conduit for cold air in the winter or hot air in the summer.


Finally, if your attic or basement is not insulated properly, you’re making it very difficult for your heater to keep your home warm. Check your household insulation to make sure it is sufficient or if there are areas for improvement. Proper insulation keeps your house warmer in the winter and cooler in the summer.
