How to Locate Cold Air Drafts


Cold air drafts are typically noticed more often during the winter months. That's the time when you may notice a cold draft of air coming through some unidentified crack. This is a common issue that contributes to an increase in heating bills because of wasted energy. In order to resolve this issue, the source of the cold air drafts have to be located. Sometimes, it may be difficult to immediately locate where the draft is coming from, but by using these guidelines you should be able to determine the location.

Things You'll Need

  • Tissue wrap
  • Coat hanger
  • Candles
  • Locate cold air drafts by placing lighted candles near windows and doors in your home to detect where the draft is coming from. You can also hang a coat hanger with plastic wrap attached to it. When the draft enters inside the house, the plastic wrap will alert you. Then, you can follow the direction the draft is coming from.

  • Inspect cinder blocks for signs of cracks or visible gaps. Look carefully at the mortar between blocks when trying to locate cold air drafts. Use a pencil to mark the area if you are planning on fixing it at a later date.

  • Determine if insulated areas are dirty, which can indicate that there is a leak. Inspect attic access panels and doors for signs of defects.

  • Look between the drywall or the plaster and the trims in your house for signs of gaps. Inspect plumbing outlets as well as where the vents penetrate the walls or ceilings.
