Invisible drafts around windows, doors, outlets, and ducts silently heat the outdoors while you pay for it. Most homes have 5–15 unseen gaps costing $200–$500 per year.
Stand next to a closed exterior door on a windy day. If you feel air on your ankle, the weatherstripping is shot. Run a business card along the frame — if it slides through, air does too.
Remove a wall plate and place your hand behind it. If it's cold, your insulation has settled or the outlet box is leaking into the wall cavity. Foam gaskets cost pennies to fix.
Hold a lit candle or thin thread near window corners. Even a barely-perceptible flicker means measurable air exchange — multiply by draft hours per day and it adds up fast.
The attic hatch is often uninsulated and poorly sealed. If it feels like a refrigerator door in winter, you're losing 10–15% of your heating budget through that panel alone.
Small gaps around frames, outlets, and hatches create continuous air exchanges. You heat the outdoors in winter and cool it in summer.
Use the Door Frame Test, Candle Flicker Test, and Infrared Scan to map every leak. Rank them by size — seal the biggest first.
Foam sealant for outlets, weatherstripping for frames, spray foam for gaps — then verify with an IR camera or thermometer.
