  1. Suit up. Don’t forget to wear protective gear when you’re working near insulation or exposed areas in your home–this includes gloves, goggles, and respiratory protection. Try to always do your work on a cool day.

  2. Smoke it out. Light some incense near the seams of doors, windows, or walls in your house. If the smoke moves rapidly back and forth, it means there are air drafts present that indicate a leak.

  3. Try a paper test. Take a dollar bill, and carefully close it in the seams on all sides of your doors and windows. Then give it a tug. If you can easily pull it out without resistance, that seam on your door or window is likely leaking air.

  4. Shed a little light. Wait until it’s dark, then grab a partner and have them stand outside. From indoors, shine a flashlight out through possible gaps. The rays of light seeping through should reveal most medium and large leaking areas.

  5. Seal it up. Following package instructions, apply caulking or weather stripping to seal any cracks you find. For gaps between stationary building parts or materials seal with caulking. To stop leaks around movable pieces (like doors and windows) use weatherstripping.

  6. Call the pros. A professional energy audit can also help you detect the location of any leaks that visual tests might not catch. Follow our tips here for more information.
