Stopping Drafts From Old Windows: Practical Fixes That Work

Figure Out Where The Air Is Getting In

If a room feels chilly near the window, the air leak may be coming from the sash, the frame, the weatherstripping, or the gap where the trim meets the wall.

You can also hold a tissue or incense stick near the frame and watch for movement, which makes small leaks easier to spot.

How To Keep New Drafts From Coming Back

The goal is not heavy upkeep, just regular attention before small failures turn into comfort problems again.
