A drafty window can make one room feel noticeably colder than the rest of the house all winter. One quick test is to shut the window completely and watch the curtain, because if it's moving, air is getting through.
What that draft actually means varies quite a bit:
▪️A minor air leak is often just a weatherstripping or caulk fix.
▪️Failing seals show up as fog or moisture trapped between the panes, and that glass unit can't be resealed.
▪️Damaged or rotting trim can be the whole problem while the window itself is perfectly sound.
▪️A window that sticks, won't lock, or has a spongy frame is usually closer to replacement.
Those four situations look almost identical from your living room and cost very different amounts to address, which is why we'd rather assess it than guess.
When replacement does make sense, Roof Puppy will walk you through the options, including double-pane glass and double-hung configurations, and explain what each one changes. Newer windows can reduce air leakage and even out temperatures from room to room, though how much difference you notice depends a great deal on what you have now.
