Can You Change the Colour of uPVC Window Frames?

There are generally two options for altering the hue of the frames and sills in your home: removing the white vinyl joinery and installing a coloured one, or spray painting the old joinery with the hue you desire. The main difference between the two choices is the price. So, which is more expensive?

Naturally, installing new coloured joinery would take a greater toll on your wallet. Manufacturers mass produce white PVC, whereas the production of dark vinyl is dictated by existing demand. Thus, adding a hue to the PVC components during the manufacturing process increases the final price of the joinery because the price of the dyeing agents is also included.

A cheaper alternative is to have your frames and sills painted with a special uPVC spray. The final result is not much different from having new coloured joinery installed. The only downside of this option is that you may need to take some time off from work to paint everything yourself or hire someone to help out.

If you’re concerned about the general aesthetic of your home and whether dark-coloured uPVC would fit it, you have nothing to worry about! There is a wide variety of darker shades and all of them bring a classic look to brick and stone houses alike.

So, you don’t have to settle for black uPVC, which sometimes can be in stark contrast with the walls of your home depending on their colour. If this is the case, anthracite grey windows are just the windows for you – they are almost black in colour, but have a softer look. As for the internal windows, you can always request a dual-colour uPVC windows – darker on the outside, white on the inside. The possibilities are endless!

Does Black Upvc Fade?

Probably one of the more common concerns regarding black upvc doors and windows is whether the colour fades. The short answer is yes, but it does so over the span of 10-15 years.

As with any other product, constant usage and poor maintenance will lead to discolouration. When it comes to dyed goods, any wear and tear is much more visible because of the striking contrast in hues between the blemished and non-damaged . That’s why you need to take proper care of your windows and doors, regardless of the colour.

  • Climate: Weather conditions can significantly speed up the discolouration process. If you live near the seaside the level of air humidity and salt deposits can corrode the protective coating of the window frames, doors, handles and even the insulation seals. Sunlight can also lighten the original shade of the uPVC over time.
  • Cleaning: Window washing should always be done with non-abrasive tools and detergents. Otherwise you risk visible scratches and discoloured blotches on the window treatments.
  • Maintenance: It goes without saying that routine cleaning and inspection are a must. We always recommend a thorough wash of your windows at least twice a year – in the spring and in the autumn. Skylights are more susceptible to climate damage than any other type of windows, so learning how to properly upkeep your skylight will help you avoid potential water leaks, structural damage and draftiness.
You can conduct the bi-annual inspection of your windows and all the surrounding treatments during the washing process. It may double your cleaning time, but your windows will serve you for longer.
