How to maintain PVC and aluminium windows so they last longer

A little regular care can significantly extend the life of your windows and doors and keep them operating smoothly for years.

Windows and doors are among those elements of a home we only pay attention to when something stops working smoothly. Yet a little regular maintenance can significantly extend their lifespan and keep them easy to operate for many years.

Maintaining PVC windows

PVC windows are low-maintenance, but a few simple habits help them last longer.

Cleaning the frame

Clean with warm water and a mild detergent. Avoid abrasive cleaners or solvents that can damage the surface finish.

Lubricating the hardware

Once a year (for example in autumn, before the heating season), lubricate the hinges and locking mechanisms with silicone or a dedicated hardware oil. This keeps them easy to open and prevents wear on the mechanism.

Checking the seals

Once a year, inspect the rubber gasket – is it dried out, cracked or losing elasticity? A worn seal should be replaced to preserve thermal insulation.

Maintaining aluminium windows

Aluminium profiles are weather-resistant, but they have their own care rules.

Cleaning the surfaces

Aluminium profiles withstand the weather well, but regular cleaning of dust and dirt preserves their appearance and prevents dirt build-up at joints.

Checking drainage holes

Aluminium systems often have drainage holes to channel water away. Make sure they are not clogged with leaves or dirt, especially in autumn.

Hardware maintenance

Just like PVC windows, aluminium system hardware needs periodic lubrication to keep it operating smoothly.

Maintaining doors

Doors are used every day, so their mechanisms wear out faster than window hardware.

Lubricating hinges and locking mechanisms

Regular lubrication prevents squeaking and keeps the door easy to operate.

As with windows, door seals wear over time and should be checked regularly.

Threshold

Make sure the threshold is clean and not blocked by dirt that could prevent the door from closing tightly.

A simple yearly maintenance schedule

In spring

From time to time

A visual check – any draughts, stiff opening or visible damage?
