So, how do you keep your windows and doors looking fresh year-round, giving your home that all-important kerb appeal that makes people stop and look when passing by?

In this short guide, we’ll outline some easy-to-follow cleaning and maintenance guidelines for your uPVC windows and doors to keep them fully functional and looking fresh.


Maintaining uPVC Windows


The best way to clean uPVC window frames

Always use warm water and avoid using stringent detergents that might otherwise cause long term damage. If your frames are showing signs of discolouration, it could be tempting to use a strong chemical agent to restore your windows to their former glory. But it’s much better to use mild cleaning fluid.

Condensation in your windows? Don’t panic

If your uPVC windows were fitted recently but you’ve noticed condensation on the inside, this isn’t necessarily the sign of a defect. Moisture is usually caused by warm air landing on a cold surface. Therefore, it’s not usually a reason to worry.

However, if you have concerns do call a trusted local installer who can assess your double glazing. Regularly wiping away accumulated moisture will promote the lifespan of your uPVC windows by preventing corrosion or the build-up of mould.
Other top tips…

  • Avoid using pressure washers to clean your glass. It can damage the Otherwise, the insulating gas layer or the glazing itself.
  • Lubricate your hinges frequently to ensure your windows open and close fluidly and remain free from rust.
  • Check the integrity of your seals often to prevent unnecessary deterioration and reduced performance.
  • Use a vacuum cleaner to remove dust from the tracks of your windows to avoid issues opening and closing them.

Maintaining uPVC doors

The rules for cleaning uPVC doors are nearly the same as for windows. Avoid using acidic cleaners (for example, creams or scouring powders).  Instead, use hot soapy water. Don’t forget to rinse away suds and debris with fresh water afterwards.

Door handles see a lot of frequent use. This makes them a breeding ground for germs and bacteria. Using a standard antibacterial spray often will help ensure your uPVC doors remain germ- and bacteria-free all year round.

As before, using a hoover to remove dust, grime, and general debris will help keep your windows looking good as new.

It’s important to note that the frame must always come first before cleaning or maintaining other elements of your uPVC door.

uPVC is smooth, making it easy to clean. It’s not prone to corrosion or rotting either — as can be the case with traditional timber windows which must require be meticulous care.

In terms of cost, uPVC windows and doors are less expensive than their wooden or aluminium equivalents. But they can be equally stylish. For example, timber foils can be added.
