Locate air leaks

Look around your house for gaps or cracks that could be leaking air, including the attic floor, edges of doors and windows, electrical outlets and switches, and pipe entrances.

Light an incense stick and hold it close to window edges and other possible leaks. If the smoke coming from the stick goes horizontal, you’ve found a crack.

To test doors and windows, close them on a used piece of paper laying against the frame. If you can remove the paper without tearing it, then your seal could be tighter.

**How this helps**

A little air flow in a house is a good thing, but too much and you could be losing your nice (expensive) warm air to the freezing outdoors. Checking around the house will help you to understand where your leaks are and whether you should consider sealing them.
