Windows and doors are a big investment, and a little regular care helps them last. None of this takes long, and most of it only needs doing once or twice a year.

Clean the frames gently

  • uPVC and aluminium: warm water with a little washing-up liquid and a soft cloth is all you need. Avoid scouring pads and solvents, which can scratch or dull the finish.
  • Timber: wipe down with a damp cloth, and keep an eye on the paint or stain. Bare or flaking areas let water into the wood.

Avoid using a pressure washer close to the glass, seals or gaskets, as it can force water past them.

Keep the drainage slots clear

Most uPVC frames have small slots along the bottom edge that let rainwater drain away. If they block up with dirt or leaves, water can collect inside the frame. Clear them out gently with a soft brush or a cotton bud.

Look after the moving parts

Hinges, locks and handles work best when they are clean and lightly lubricated. A light machine oil on hinges and locking points once or twice a year keeps things moving smoothly. If a window or door starts to drop, stick or become hard to lock, have it adjusted before the problem gets worse.

Check the seals

The rubber seals around the opening parts keep out draughts and rain. Check they are seated properly and not cracked or perished, and wipe them clean when you clean the frames.

Watch the glass

  • Mist between the panes means the unit's seal has failed. It will not clear up on its own.
  • Chips and cracks let moisture in over time, so it is worth replacing the glass sooner rather than later.
  • Condensation on the room side is usually about moisture in the house. See condensation on the inside of your windows for tips.

Timber needs a little more

Timber windows can last for a very long time if they are kept protected. Repaint or re-stain them when the finish starts to wear, and check the corners and the bottom rail for soft spots.

When the glass fails

Even well-kept windows eventually need new glass. When that happens, the frame is usually still sound, and a replacement sealed unit made to fit is all you need. See how long double glazing lasts, or get in touch for a free quote.
