🚪 Draft Stopper Cost Calculator

Estimate the cost of sealing drafts around doors and windows. Covers door sweeps, weatherstripping, foam tape, outlet gaskets, and caulk.

Project Details

Exterior Doors (doors)

Number of exterior doors that need draft sealing

Drafty Windows (windows)

Number of windows with noticeable air gaps or drafts

Draft Severity (1=minor gaps, 2=visible drafts, 3=major leaks)

1 = small gaps only, 2 = you can feel cold air, 3 = visible light or heavy air movement around frames

✓ Hold a lit incense stick around door and window frames on a windy day to find every leak before buying supplies
✓ Replace worn door sweeps first — a worn sweep can account for as much air loss as a 3-inch hole in the wall
✓ Outlet and switch plate gaskets on exterior walls are a commonly missed source of cold air infiltration
✓ Rope caulk is the easiest temporary fix — it peels off in spring without damaging paint or trim
