FACTORS AFFECTING DOUBLE GLAZING

There are a number of factors that will affect how much you pay for your home’s double glazing. These include:

  • The number of windows and doors
  • The type of windows and doors
  • Quality of glass
  • Type of window and door locks
  • Access to the property
  • Any scaffolding needed
  • Where you live

It’s also useful to remember that double glazing quotes don’t usually factor in any special requirements, such as coloured door and window frames, A-rated windows, lead framed gloss or special locking mechanisms.

AVERAGE COST OF DOUBLE GLAZING

On average, double glazing costs $940 per window – but it can be at least a couple of hundred dollars cheaper, with top quality double-glazed windows, available for as little as $500. On top of this, installation can cost around an extra $450, but it’s worth it for that professional touch. 

Bear in mind that if your installer needs to put up scaffolding to get to your window, that’ll also cost extra – and the higher the window, the higher the price. 

If you’re getting a bay window replaced, installers will also need more time (and, therefore, more money) to fit it. It’ll take about half a day for two people, whereas simpler models like casement windows can be done and dusted in a couple of hours.
