  • What is the price of UPVC windows?
  • All of our designs and installations are completely unique and based on your preferences. This means prices can change when it comes to colour, style and other modifications such as handles.

    As a guideline, our uPVC windows start from £550 per window. We also offer a free Composite or French Door worth up to £1,800 when you opt for a full house refresh on your windows.

  • What are UPVC windows?
  • UPVC is the material used to make the windows, unplasticised polyvinyl chloride. It is a strong but lightweight and low-maintenance material perfect for keeping the warm air in. UPVC is a great substitute for painted wood and a cheaper alternative to timber or aluminium. This is why uPVC windows are often found with a wood grain effect. Choose your uPVC windows from a wide range of styles to suit your home, and then trust our experienced team to manage the project with minimum fuss.

  • What is the difference between PVC and UPVC windows?
  • PVC and uPVC are two vinyl materials used in the construction industry thanks to their durability and flexibility. However, despite what you may see online, PVC is not used to make windows due to its chemical composition. PVC is more commonly used for siding and fencing, whereas uPVC is used for windows and doors.

  • How long do UPVC windows last?
  • How long your uPVC windows will last depends entirely on how well you look after them. As previously mentioned, mobilising the hinges throughout summer, and cleaning out the drainage holes will ultimately give your uPVC a longer lifespan.
    Following our professional aftercare advice is the best practice to keep your windows looking new for longer. Follow our tips and your uPVC windows can last anywhere between 20 and 35 years.

  • Are wooden windows better than uPVC?
  • Wooden windows have different properties to uPVC and may be more suitable for homeowners willing to pay more money and spend more time maintaining them over the years. Whilst the argument could be made for wooden windows lasting much longer than uPVC, this longevity is not guaranteed and can only be achieved with frequent maintenance and care. In comparison, uPVC is more affordable and can be maintained quickly and easily.

  • Do uPVC Windows warp in the sun?
  • It's completely normal for windows and doors to swell during the hotter months. Like timber and composite, uPVC windows suffer from swelling. UPVC expands and contracts slightly in more intense weather conditions, but there are some ways to combat this swelling.
    You can cool down your uPVC windows by spraying them with water, or by gently patting them with a damp cloth. This can help the material to shrink back down to size but as mentioned, this swelling is natural.

  • Can you fit uPVC windows yourself?
  • Whilst it is possible to do so, we don’t recommend that you attempt to fit them yourself. It wouldn’t be prudent to spend hundreds of pounds on new uPVC windows, to then risk compromising the security of your home by installing them on your own.
    Our professional workmen are here to measure up and fit your new uPVC windows, to guarantee the outstanding security that you’ve paid for.
