7 signs it's time to replace your old windows
A draft near the frame, condensation between the glass panes, or a rising heating bill: here are the clear signs that your old windows are costing you more than a replacement would.
Many homeowners put off replacing their windows until an obvious problem shows up, but the real cost of old joinery shows up in the heating bill, not just in looks. Here are the signs that tell you it's time.
Signs to watch for
- You feel a draft near the frame, even with the window closed
- Condensation or fog appears between the glass panes of the double glazing (a sign the seal has failed)
- The window opens or closes with difficulty, or the handle sits crooked
- The wooden frame has rotted, or the PVC one has yellowed and warped
- Outside noise is noticeably louder than before
- Mould appears on the sill or around the frame
- The heating bill has gone up with no clear explanation
Repair or full replacement?
If only the hardware is worn, sometimes an adjustment or new seals solve the problem. But if the frame is warped or the sealed unit has failed between the panes, a repair is temporary, while full replacement is what actually cuts heat loss long-term.
Frequently asked questions
Is it worth repairing old windows instead of replacing them?
It depends on the profile's condition. If the frame is sound and only the hardware or seals are worn, a repair may be enough. If the profile is warped or the glazing has failed between panes, replacement is the durable solution.
How quickly does a new window pay for itself?
It depends on the current condition and heating use, but modern PVC windows with low-e glazing noticeably cut heat loss compared with old joinery with worn seals.
