What is the lifespan of aluminium windows?
Aluminium windows commonly last 30 to 45 years, and well-made frames with a quality powder coat can last longer. The frame rarely fails first. Seals, hinges, handles and the glazed units usually wear out sooner, so lifespan depends on finish quality, installation and basic upkeep.
What wears out first on aluminium windows?
- Gaskets and weather seals, which harden and shrink with age
- Sealed glazed units, where a failed seal shows as misting between the panes
- Handles, hinges and locking hardware, which are replaceable without changing the frame
- Blocked drainage slots, which let water sit in the frame
How long does the powder coating last?
The powder-coated finish is the part that ages. A good coating holds colour for decades, but quality varies between suppliers, so ask for the coating guarantee in writing and check what it covers.
How do you make aluminium windows last longer?
- Wash the frames with mild detergent a couple of times a year
- Clear the drainage slots and lubricate the hinges annually
- Check seals and hardware for wear
- Have the frames fitted level and sealed properly, as poor installation shortens life
Lifespan depends on the coating and installation more than the metal. Exposed sites need a higher-grade finish, so the specification matters. Jake surveys every job himself, and JMF Windows Oxford fits aluminium windows with a 10-year guarantee and Certass registration.
