Practical Ventanas Cortizo guide

Aluminium and PVC window maintenance

How to care for aluminium and PVC windows: cleaning, gaskets, hardware, drainage and adjustment signs.

Basic cleaning

Aluminium and PVC require little maintenance, but clean frames and glass with mild products and avoid abrasives.

Gaskets and hardware

Keep gaskets clean and flexible. Hardware may need occasional checking or lubrication depending on use.

Drainage

Many windows include drainage channels. If blocked by dust or leaves, water may accumulate.

Daily use

Do not force handles, avoid wind slams and use tilt-and-turn positions correctly.

When to request a check

If air, new noise, difficult closing, unusual condensation or leaks appear, ask for professional adjustment and sealing review.
