Windows do not usually fail overnight. They slip from fine to worn gradually, so the signs are easy to miss until a draft or a fogged pane makes it obvious. Knowing what to look for helps you plan a replacement before comfort and energy bills suffer. Here are the clearest signs it may be time.
Drafts and Cold Spots
If you can feel air moving near a closed window, or a room has a cold zone by the glass in winter, the window is losing heat. Older single-pane and early double-pane windows lose far more heat than modern energy-saving windows, and no amount of curtains fully makes up for it.
Rising Energy Bills
When heating costs climb without an obvious reason, tired windows are often part of it. Heat escaping through poor glass and gaps makes the furnace work harder. Upgrading to sealed, insulated glass with a Low-E coating is one of the more noticeable ways to bring bills back down.
Fogging or Moisture Between the Panes
Condensation on the inside surface of a window in winter is common and usually about indoor humidity. But fogging or water droplets trapped between the panes is different: it means the seal on the insulated unit has failed. That glass cannot be cleared and the unit needs replacing, which we cover under why windows leak and fog.

Windows That Stick or Will Not Stay Put
A window that is painted shut, hard to open, or will not stay up is more than an annoyance. It can be a safety issue, since a bedroom window may be needed as an emergency exit. Warped frames, broken balances and swollen wood all point toward replacement. This is also a chance to reconsider the window style for how a room is used.
Visible Damage, Rot or Draughty Frames
Cracked glass, rotting or crumbling frames, peeling seals and daylight visible around a closed sash all say the window is at the end of its life. Wood frames that are soft to the touch have usually let water in. Once the frame is going, patching rarely lasts, and replacement is the sounder choice. It is worth avoiding the common mistakes when you do.

FAQs
The common signs are drafts and cold spots near the glass, rising heating bills, fogging between the panes, windows that stick or will not stay put, and visible rot or damage to the frame.
Fogging between the panes means the sealed unit has failed, and that glass cannot be cleared. The glass unit needs replacing, though the frame can often stay if it is sound.
Condensation on the inside surface is usually about indoor humidity, not a fault. Moisture trapped between the panes is the real warning sign, because it points to a failed seal.
It varies with the type, materials and climate, but many windows last a couple of decades or more. Frames that rot or seals that fail can shorten that, so condition matters more than age alone.
Not necessarily. You can replace the worst first and do the rest in stages, though doing several together can be more cost-effective and gives a consistent look. It depends on budget and how many are failing.
