How to Clean & Maintain your Timber Effect uPVC Windows

Windows, redefined.

At Evolution we often tell people that our windows are easy to look after, both in terms of cleaning and maintenance. However they do require a little attention now and again! This quick guide will show you what is required, as you will see it's not a lot to keep your timber effect uPVC windows and doors both looking good and functioning well for years to come. 


Window & Door Frames

Wash frames with a soap and water solution at least:

  • Every three months in areas of heavy vehicular traffic
  • Every six months in rural areas

Clean with a non-abrasive proprietary cleaner, suitable for plastics using a soft cloth.

  • External dirt and grime should be removed from the glass surface using a solution of soap and water.
  • Any household glass cleaner may be used with a soft cloth.

Leaded Glass

  • Take care when cleaning leaded glass as excessive pressure can dislodge the lead from the glass surface.
  • Warm soapy water moderately applied with a cloth will prove an adequate cleaning method.

Note: Avoid all solvent based or abrasive cleaners. Take care not to disturb silicone pointing sealants.

uPVC Frames

uPVC requires no maintenance other than cleaning. In the event of damage please contact your local Evolution authorised installer. Periodically and where accessible, clear drainage holes which can be seen when you open your windows and doors.

If the gaskets are broken or damaged and draughts are felt around the unit, ensure prompt replacement by contacting your installer.

An oil or light grease applied to the mechanisms and stays once a year will enhance corrosion resistance.
