How do I maintain my uPVC windows?

We like questions about how to maintain uPVC windows. Some people think that uPVC windows don’t require any maintenance at all! UPVC is low maintenance, but uPVC windows have moving parts that need occasional lubrication. They also pick up airborne dirt, debris and sticky spider webs – just like anything kept outside. Therefore, wiping with a damp cloth in and around the frames is essential to keep them opening smoothly.

Standard white double-glazed windows may look like any other plastic. But, energy-efficient uPVC windows are manufactured in a highly sophisticated process – from design to completion -and feature massive technological innovations. The great advantage of uPVC is that you can keep your windows looking great for years with a bit of time and without the need for expensive chemicals or paints.

The best of the best double-glazed windows have a specially designed multi-chamber structure and high-quality external finish. The quality of the finishing PVC makes each window easy to maintain. Put uPVC under a microscope, and you will find exceptionally smooth material, so it doesn’t allow dirt and dust to become ingrained.

Maintaining uPVC window frames.

Have you recently run a clean cloth (soaked in plenty of water) along a uPVC window sill? The dirt is very easy to shift. In most cases, a quick wipe-down with a wet cloth is all you need. Removing the build-up of dirt and pollens keeps your window frames looking bright as new for their lifetime.

Where there is more stubborn dirt or stains, use a specialist uPVC cleaner. Don’t use any form of abrasive or chemical cleaner. Take your time with the right products, or you’ll damage the smooth surface of the window. If you use other cleaning products, you’ll create many micro-scratches. Scratches in uPVC collect dirt, making it much harder to keep window frames clean in the future.

Foiled and woodgrain double-glazed windows give all of the advantages of PVC windows but with design and colour flexibility. You can choose a unique statement design or replicate the appearance of traditional timber in low-maintenance and high-performance uPVC. Again, a regular wipe-down with a damp cloth (with mild detergent if necessary) will be enough to keep your foiled windows looking their best.

Again it would be best if you didn’t use abrasive cleaners like Ciff/Jiff or solvent-based cleaners. Any chemical cleaner will weaken the bond between foil finishes and the uPVC window substrate, leading to a failure, peeling and discolouration.

Maintaining window glass

When you want to clean the glass in your windows, pick your moment. A dry, dull, overcast day that isn’t too hot is perfect. On hot days, window cleaning water will dry onto the glass, creating streaks.

Again, don’t use any harsh chemical cleaning products. Choose a glass window cleaning product or mild detergent in warm water. Use a soft cloth or soft sponge to remove debris and dirt. Then use a squeegee to remove the excess. A good squeegee delivers the all-important streak-free finish. We’d recommend starting in the top corner of your window and working in a series of horizontal strokes down the glass.

Even self-cleaning glass will occasionally need a wipe down too, but take care not to damage special coatings. Use only water; if you decide to use a mild detergent, it must be colour-free. Only use a very soft cloth, not a squeegee.

Remove excess debris carefully before it is carried into drainage holes. As you wash your windows, be careful not to cause potential blockages. uPVC window frame drainage holes allow water trapped between the frame and opening sill to escape. Regular brushing out is a good idea. Or use a vacuum if you can do so safely. Remove leaves, dirt or other items from the track to allow it to drain freely.


Maintaining window hardware and hinges.

Make sure that your window locking mechanisms and seals are correctly lubricated. We recommend silicone-based lubricant. Oil can build up in hinges and locking mechanisms over time, so a small amount of silicone-based lubricant on a cloth is best. Wipe it along tracks and around each seal to keep all the windows opening and closing.

A wet cloth should also clean window handles and hinges. Do this while wiping down frames, but again, use only water or a very mild colour-free detergent. Don’t’ use WD40 or heavy oil to lubricate windows, locks or hinges.

The good news is that you don’t need to clean window frames and hardware very often. Every three to four months is recommended. Clean uPVC double-glazed windows and doors look great and are energy efficient for longer-lasting money savings.
