Detect and Seal Hidden Home Drafts

Cost Savings

Checklist Tasks

• Test window frames with smoke to reveal air leaks.
• Check exterior wall outlets for drafts; install foam gaskets if needed.
• Inspect baseboards for gaps and seal with caulk to block air infiltration.
• Feel attic hatch edges for temperature changes and add weatherstripping.
• Test door seals with a dollar bill; replace worn weatherstripping.
• Shine a flashlight outside at night to spot light leaks through air gaps.
• Examine fireplace dampers for proper closure; use a chimney balloon if unused.
• Seal gaps around utility lines with silicone caulk to prevent air entry.
• Check floor-to-wall joints for drafts, especially in older homes.
• Inspect dryer vent exits for loose fittings or missing caulk.
• Seal attic knee walls and exposed framing to prevent heat loss.
• Review garage-to-house door weatherstripping for overlooked drafts.
