If you are yet to install double glazed windows on your home, the cost of doing so may have put you off. If so, you might be considering buying your windows from a High Street DIY store and installing them yourself. This idea may be very tempting, but is it a good plan? Knowing the pros and cons of both doing it yourself and getting an installer to do it for you will allow you to make the right choice for you and for your home.

We all know that double glazing is great for our homes and our pockets. They will save energy by keeping our homes warmer, reduce condensation and also improve the value of our homes. In fact you can save up to £160 per year on energy costs just by installing good quality double glazing. But what about doing it yourself?

The pros of DIY double glazing

  • You will most probably save money. An average terraced home may expect to cost around £2000 to £3,000 for installed double glazing, while DIY versions can cost around £1200 to buy and will cost little to install, other than your time.
  • You can complete the job in your own time and even as and when you can afford to purchase the windows. This means that disruption can be limited to when you want it.
  • You can avoid having to choose the right installer – avoiding possible rogue traders and poor quality installation.
  • You can choose the quality of your windows, knowing that they are sold by an established retailer with comeback if they go wrong.
  • If you are a skilled DIYer and use the right thermally efficient materials, you can get an excellent result that could improve the value and look of your home.

The cons of DIY double glazing

  • Unless you have a good level of DIY skills, the right tools and a head for heights, you may find installing double glazing challenging. The finish needs to be perfect to achieve the thermal efficiency you need. So good installation is important.
  • You may need to hire scaffolding for a safe installation and this can be expensive.
  • Some of the off the shelf double glazing units can be basic – not allowing you the choices you can get from specialist installers. This includes different materials, different colours, triple glazing and specialist glass options.
  • You may find that if you have to order special sizes, the costs of doing so may outweigh the costs of installation.
  • As well as buying your windows, you will need sills, expanding foam, insulation and plastic strips to cover gaps. These items add up in terms of costs.
  • Installers can buy in bulk and may therefore offer great deals.

It is entirely up to you whether you want to pay for your installation or give it a go yourself. But do bear in mind the importance of knowing what you are doing so you can thoroughly enjoy the results of your hard work.
