uPVC windows are very easy to maintain. They should be wiped down with warm, soapy water and then dried with a soft cloth. Window frames can be damaged by abrasive cleaners so these should be avoided.
Glass can be cleaned with a liquid glass spray cleaner.

“The whole process of replacing my windows using First Home Improvements, from initial consultation/quote, through detailed survey to the installation, went smoothly. The installation also took place ahead of the intial estimated date, which was a bonus.
The installation team of Michael Perry & Raymond Perry arrived on time and were friendly and easy to deal with. They worked efficiently and produced a very neat finish inside and out. Their clean up job afterwards was also thorough.
Very happy with the quality of the windows and the installation. Thanks.”

First Home Improvements is company with a good reputation and a great selection of uPVC window styles. However, other companies may be a better fit for you, especially if you’re interested in different frame materials.
Anglian, our top choice of double glazing company in the UK, is similarly priced to First Home Improvements, offering a 10-year guarantee on all parts and labour and a 15-year guarantee on gas-filled windows. Its uPVC windows are rated A to A+ for energy efficiency.
Another benefit of choosing Anglian to supply your new windows is its selection of frame materials, including timber and aluminium. Additionally, many of its window styles (tilt and turn, sliding sash and casement) are SBD-approved for their high security standards.

If you are noticing your energy bills increasing, draughts, or condensation between the panes of glass inside your double glazing, it may be worth updating your double glazing.
Although the sealed units can last for around 30 years, they can eventually become faulty. If this falls within your warranty period, contact your installer for replacement windows. Outside this period, consider the benefits you’ve enjoyed from having double glazing when thinking about getting new units.
Triple glazed windows are becoming increasingly popular, and many installers offer this option. Although pricier than double glazing, the addition of an extra spacer and glass panel increase the insulation offered by up to 40%. Other benefits increase over double glazing, too, including sound insulation and home security.
Misting occurs when the seal on a double glazing unit become faulty, and this can be repaired by a professional, although the issue may return.
A small hole is drilled through the frame and a desiccant agent pumped in. This will absorb the moisture, leaving the space between the glass panes dry. This can be a risky process, and there’s no guarantee that the window won’t be damaged.
Many double glazing providers offer customisation of their uPVC window frames using a range of colours and finishes. This makes is easy to increase the appeal of your home, and give the windows a personal touch.
Woodgrain effects, such as oak, beech and maple, are popular choices, but colours, especially bolder hues are rapidly increasing in popularity. Blues and greens offer wide palettes, with the more subtle tones blending well with period architecture. Braver colour choices, such as burgundies and yellows bring a stylish splash of contemporariness to any exterior.
