Drafts & Windows

Simple ways to find drafts, improve window comfort, and reduce cold air leaks.

How to use this cluster

Use this section when you can feel moving air, see curtains shifting, notice cold trim, or suspect windows and doors are leaking. Draft fixes work best when the leak is identified first; guessing between caulk, weatherstripping, film, or curtains often wastes time.

Do not seal randomly around electrical boxes, wet trim, rotten frames, or combustion appliances. Those situations need safer diagnosis before DIY air sealing.
