How Much Do Replacement Windows Cost?

Last Updated Mar 12, 2015 · Written by Rob Schneider


The time comes when, for practical or aesthetic reasons, you decide it's time to replace your windows. How much are they going to cost? It will depend on the type of windows you choose, their size and the difficulty of the job.

Types and Costs of Replacement Windows*

 
You will have to get quotes for your windows, but in general, the material any size and type of window is made from will determine its cost relative to other materials. For example:
  • UPVC is the cheapest material and has good insulating properties.
  • Aluminium window frames are not good insulators, but are moderately priced and relatively maintenance free. Some aluminium windows now insulate better than others, but cost more.
  • Composite windows are relatively new on the Australian market. Made from fibreglass and resin, they are in the mid-price range. Some composite windows have aluminium exterior frames for greater durability and composite interior frames that resemble timber and can be painted the colour of your choice.
  • Timber framed windows are the most expensive and require the most maintenance, but if made from quality timbers, are a timelessly stylish option.
The frame style also adds to the cost of a window. A fixed window will be cheaper than a window that opens and prices go up as the window design and opening mechanism becomes more complex. Some popular window styles that are very good for cross ventilation include hopper windows, louvre windows and double hung windows. They will cost more than fixed windows, but may be essential for good ventilation.

Single pane plain glass is the cheapest type of window glass, but today, most councils mandate safety glass for most areas of the home. Different types of window tinting  or low-e glass will add more to the cost of a window, but the biggest jump in price is for double glazed windows, which typically cost 25-50% more than single glazed windows. A good glazier in your area can help you choose the best and most cost-effective type of glazing for your windows depending on their orientation in your home and other factors.
 
With so many options to choose from, getting quotes for replacement windows can be a hard job. To make it easier:
  • First choose your ideal frame material and window style.
  • Think about whether you need windows for ventilation.
  • Decide whether or not you prefer single or double glazing.
  • Measure the size of your existing window openings.
Most window suppliers/installers will sell a variety of window styles and glazing options, but not all supply windows made from every type of window material. The easiest way to get comparative quotes for replacement windows made from your preferred material is online, using our get quotes service. Specify your preferred material first and your query will be sent to suppliers in your area most likely to have what you're looking for. If you want to compare prices for two types of materials (UPVC and timber, for example), that's no problem, either.

Not sure which type of replacement windows you want? Try browsing through our Window Design Ideas pages and you'll find hundreds of examples. Now imagine how your favourite replacement windows would look in your house and how they would improve energy efficiency and ventilation for you. It might take a little time, but it will be worth it, because the replacement windows you choose today will be with you for as long as you own your home.
