Check the perimeter where the window meets siding, trim, or masonry, and look for cracked caulk, separated joints, or spots where the sealant has pulled away.

Raise and lower double-hung sashes, swing casement windows open and shut, and make sure latches actually pull the window tight.

A fresh bead of paintable caulk, replacement weatherstripping, rope caulk, or interior shrink film can help reduce drafts without changing the window itself.
