Yeah, those sound like classic signs that your sash windows need repair. The difficulty in opening could be due to broken sash cords or misaligned frames. The draft is often a sign of deteriorating putty, loose glazing, or gaps forming in the wood, which can lead to higher energy bills if left untreated. Cracking paint and potential wood rot are definitely things you don’t want to ignore—once moisture gets in, the decay spreads quickly, and at some point, small fixes won’t cut it.
Another common issue is rattling when it’s windy, which usually means the sashes have shrunk over time, creating gaps.
