How to Fix Drafty Windows
Why This Matters
Before replacing windows, try these affordable fixes that can dramatically reduce drafts.
What You Should Do
-
Identify draft source — Hold candle or incense near frame; watch for flickering.
-
Replace weatherstripping — Peel old, apply new adhesive foam or V-strip.
-
Recaulk exterior gaps — Remove old caulk, apply new exterior-grade.
-
Add interior caulk — Seal gap between frame and wall.
-
Install storm windows — Interior or exterior panels.
-
Use thermal curtains — Heavy, insulated curtains block drafts.
When to Call a Professional
