Maintenance and Cleaning

uPVC windows and doors are extremely easy to care for and require minimal maintenance but you should still clean and care for them from time to time to keep them looking and functioning like new. This advice is particularly important if you live near the sea.

White Frames

Wash with warm soapy water every six to twelve months to remove grime and atmospheric deposits, to remove stubborn stains use a strong non-abrasive cream cleaner or contact us to order specialist uPVC cleaner.

Keep drainage openings clear of debris

Coloured Frames

Frames with a coloured foil finish should only be cleaned with warm soapy water every six to twelve months. Never sand or polish a foil finish as this will damage the laminated surface. Also remember never use abrasive cleaners these will damage the surface and may alter the gloss finish.

Keep drainage openings clear of debris.

Standard Glass

All glass we supply is toughened for your safety. It can be cleaned internally with any household glass cleaner and a soft cloth, any external grime can be removed using a solution of warm soapy water. Blades are not recommended for any glass.

Cardinal Glass

If you have chosen one of our Cardinal range of products your glass has a NEAT® self cleaning coating on the outside surface. If you have not already received it, please request our advice leaflet for cleaning guidelines. The inside surface
should be treated as standard glass.


Regular maintenance is required for all hardware, even stainless steel, as they are moving parts. 

In most environments maintenance is recommended every six months but this should increase to every three months if you live near the sea or an industrial environment.

All exposed parts should be cleaned with warm soapy water and a soft cloth then rinsed clean before being given a light spray of a corrosion preventative such as WD40.

Locks and drop bolts should be sprayed with a lubricant. A tube attached to the nozzle will help concentrate the spray where you need it.

This maintenance advice is very important if you live near the sea.

Do not force stiff handles, contact us for advice.
