Locate Hidden Winter Drafts to Cut Heating Costs

Cost Savings

Checklist Tasks

• Use incense smoke at window and outlet edges to identify air leaks.
• Remove switch/outlet covers on exterior walls to check for drafts inside boxes.
• Examine attic hatches for insulation gaps and missing weatherstripping.
• Check exterior door weatherstripping for wear, cracks, and gaps.
• Shine flashlight along window frames at night to spot visible light leaks.
• Inspect recessed ceiling lights for draft entry points needing sealing.
• Run your hand along floor-wall joints to sense air inflow from foundations.
• Inspect dryer vent and exhaust penetrations for deteriorated sealant or gaps.
• Look for spider webs in corners—indicate persistent airflow.
• Check basement/crawlspace doors for unsealed rim joists and utility gaps.
• Examine window locks and latches for tightness to ensure proper winter seal.
• Compare temperatures behind curtains and in the room to reveal cold air entry.
