Aluminium windows commonly last 30 to 45 years, longer than the 25 to 30 years usually quoted for PVCu. The frame outlasts the parts around it: double-glazed units and gaskets often need attention after 20 to 25 years. Finish quality, coastal exposure and maintenance affect the result.
What helps aluminium last longer?
- A quality powder-coat finish, applied to a prepared surface.
- Regular washing with mild cleaner, avoiding abrasives.
- Good seals, hinges and drainage channels kept clear.
What shortens its life?
Salt air, harsh chemicals, damaged coating and poor installation. Aluminium itself does not rust, but it forms a surface oxide, and the coating protects the finish and appearance. Marine or heavily polluted locations need more regular cleaning.
Which parts wear first?
Gaskets, hardware and the sealed glass unit usually wear before the frame. They can often be replaced without changing the window, which extends the useful life of sound aluminium frames well beyond the first set of seals.
