Six Low Cost and Easy to Install Solutions for Eliminating Drafts Caused by Windows and Doors

By Mark J. Donovan

Are the frigid cold temperatures causing your home to feel colder, and particularly more so on windy days and nights? If so, chances are you have leaky windows that are causing drafts in the house and allowing warm air to exit your home. Not only do drafty windows cause your home to feel uncomfortable, they also cause you to dig in deeper into your wall every month for paying home heating bills.

To determine if you have drafty windows simply place your hand near the window seams on a windy day. If you can feel a breeze, then you know you’ve found the source of your cold drafts.

If you can’t feel the slight breeze with your hand also try bringing a lit candle up near the window. As you bring the candle near the window edges observe the flame carefully.

If you see the flame flicker and bend suddenly as you bring the lit candle near the window, then you know that that particular window is one of the sources of the cold drafts.

The best solution for stopping drafts from leaky windows is to replace the old windows with new energy efficient ones. However, replacing windows is an expensive proposition, and if you are renting, replacing windows is simply not an option.

If replacing windows is not an option for you, fear not. There are other low cost solutions that you can do to stop the cold drafts in your home and reduce your home heating bills.
