Maintenance of window frames

Maintenance and cleaning tips for window frames

Like nearly any part of the home, windows need care and regular maintenance to function at full capacity.Maintaining window frames is relatively easy and if done regularly, can increase their lifespan and save you money in the long term.

Timber windows will require the most attention though low maintenance types, such as aluminium, may deteriorate if dirt is allowed to remain.

Use the window cleaning tips below as a regular checklist to keep your frames in the best condition.


General cleaning tips

  • Ensure that all dirt, sand and rubbish is kept clear from tracks – preferably by vacuuming.
  • Clear any debris from weepholes in the windowsills - these holes allow water to drain out of the window system when it rains.
  • Use brushes with soft bristles so as not to scratch the frame. Once you have scrubbed off the grime, clean the surface with a wet sponge.
  • Flush hardware with clean water. A mild detergent water mixture can be used to loosen stubborn dirt. Always rinse with clean water and allow hardware to completely dry before lubricating.
  • Lubricate moving parts such as rollers, locks and hinges with a silicone-based spray. Annually is recommended though more frequent cleaning is required in seaside locations.
  • Check seals as these can perish over time and allow rain and air to enter your home.

Aluminium window maintenance

  • Aluminium windows should be cleaned with a non abrasive pH neutral detergent solution and rinsed clean to remove residue. Do not use solvents or abrasive cleaners like Jif.
  • Ensure that you remove any solvent residue before leaving the window to dry. If you don't, any remaining residue might cause oxidation of the aluminium.
  • The joins in the corners of aluminium windows can become fragile and break away from each other. Regular checks of each join will ensure that you catch any potential problems before they become harder to fix.


uPVC window maintenance

  • Use soapy water or a non abrasive pH neutral detergent solution to keep uPVC frames looking new.
  • If necessary, you can lightly scrub uPVC to remove bird droppings or other stains.


Timber window maintenance

  • Frames should be inspected every six months and treated or repainted as required.
  • Timber windows can attract mould if not regularly treated to seal out moisture.
  • If repainting, ensure the frame and joints are properly cleaned, prepared and undercoated prior to painting.


  • Lubricate sliding window tracks regularly with a light machine oil to keep the sash sliding smoothly.
