Inspect common leaks
Check around windows, doors, attic hatches, and outlets on exterior walls.
Use simple detection
Feel for drafts on windy days; use incense smoke to reveal air movement.
Check insulation depth
Look at attic insulation depth and evenness; note any compressed or bare spots.
Plan fixes
Seal gaps with weatherstripping or caulk and note areas needing added insulation.
