THE GUIDE / Windows & weather
Finding the source of a drafty window
A draft may come from an open latch, worn weatherstripping or gaps around the window trim.
What you can check
- 01
Make sure the window is fully closed and latched without forcing it.
- 02
On a breezy day, feel around the edges for moving air and note where it is strongest.
- 03
Inspect visible weatherstripping for gaps, wear or sections that have come loose.
Safety first
Avoid working from a ladder or removing window components you cannot access safely. Do not block required ventilation or emergency exits.
When to ask for help
Ask for help with damaged frames, persistent drafts, difficult-to-close windows or replacement weatherstripping.
