Replace windows when they fail rather than at a set age, but PVCu double glazing typically needs replacing after around 20 to 30 years. Timber and aluminium frames can last longer with care, though the glass seals still age. Condition is the deciding factor.
How long do different window materials last?
| Material | Typical life |
|---|---|
| PVCu | 20 to 30 years |
| Timber | 30 to 40 years with upkeep |
| Aluminium | 30 to 45 years |
What signs show windows need replacing?
- Misting between the panes
- Draughts, damp or rot around the frames
- Stiff or broken hardware
- Rising heating bills with no other cause
Does the glass or the frame fail first?
Usually the sealed glass units, often before the frame. See our PVCu windows. Phoenix Windows makes its PVCu windows in-house in Nuneaton and backs them with an insurance-backed 10-year guarantee through Assure.
How can you extend the life of windows?
- Wipe seals and drainage slots clear each year
- Lubricate hinges and locks annually
- Adjust sagging sashes before the frame wears
- Replace worn gaskets promptly
