How to Know if Your Windows Are Failing Before Energy Bills Rise

Windows usually fail gradually, so the early signs are subtle. By the time they are obvious, the glass, frame, or seals have often been underperforming for a while.

Binding, sagging, or hard latching points to frame or hardware issues. Missing or cracked materials can let air and moisture pass through. A single hot or cold room can reveal a weak window before the bill does.

If several of those checks turn up problems, the windows may be failing in a way that repair cannot fully solve.

If a house gets a lot of afternoon sun, the right glass package can make a noticeable difference in comfort, even before the thermostat settings change.
