How Long Do Aluminium Windows Last?
Aluminium windows typically last 40 to 50 years or more, far longer than uPVC. Here is what drives that lifespan and how to protect it.
Aluminium windows typically last 40 to 50 years or more, well beyond the 20 to 30 years usual for uPVC. Because aluminium does not rot, rust or warp, and the powder-coated finish resists fading, the frames stay straight, sealed and good-looking for decades with very little upkeep.
When you are investing in new windows, lifespan is one of the numbers that matters most, because it decides how often you go through the whole job again. Here is what sits behind that headline figure.
Why aluminium lasts so long
Windows fail when the frame distorts, the finish breaks down, or moisture and movement wear things out. Aluminium resists all three:
- It does not rot in damp the way timber can.
- It does not rust like steel, because aluminium forms a stable oxide and is sealed inside its coating.
- It does not warp like uPVC, so the frame stays true and the seals keep working.
The finish is what protects the years
A marine-grade powder-coated finish, baked on at a thickness of at least 60 microns over a properly etched surface, is what keeps rain, salt and UV from ever reaching the metal. It is the same class of finish used on seafront buildings, which is why the colour and integrity hold for decades rather than fading within a few years.
What about the moving parts and glass?
Two components see the most action. The hinges and locking mechanisms are quality hardware built for years of use, and a light lubrication now and then keeps them smooth. The glazed units are sealed double or triple glazing, and keeping the frames true, which aluminium does naturally, helps protect those seals from the stress that causes misting.
How to help your windows reach that age
The care routine is minimal:
- Wash the frames a few times a year with warm soapy water, more often near the coast to rinse off salt.
- Wipe the seals to keep them supple.
- Lightly lubricate hinges and locks once or twice a year.
That is the whole job. No sanding, no repainting, no treating.

Do aluminium window frames fade?
A marine-grade powder-coated finish resists UV and holds its colour for decades, far longer than painted or plastic alternatives.
What maintenance do aluminium windows need?
Very little. Wash the frames with warm soapy water a few times a year and lightly lubricate the hinges and locks now and then.
