Installing new windows is a practical way to improve comfort, natural light, ventilation, and energy efficiency in a home. However, the total cost can vary based on window type, material, and installation difficulty. If you are planning upgrades for Windows and doors in Adelaide, it is important to understand the pricing structure in 2026 so you can budget correctly.
In This Blog, We Break Down The Key Cost Factors And What Influences How Much You May Need To Spend!
1) Average Window Installation Cost In Adelaide
In 2026, the average window installation cost in Australia typically ranges from $400 to $1,500 per window. In Adelaide, standard aluminium window installations usually cost around $400 to $800 per unit. Larger windows, custom designs, or double-glazed options can increase the price due to higher material and labour requirements. These figures may also vary depending on the installer and project size.
2) Cost To Install A Window In An Existing Wall
The cost to install a window in an existing wall in Australia is higher than a simple replacement because it involves structural work. On average, labour alone can range from $200 to $450 per window. If a new opening needs to be cut into a brick or load-bearing wall, the total cost may rise to $800 to $2,000 or more. This depends on engineering requirements, wall type, and finishing work needed after installation.
3) Window Installation Cost By Type & Material
The overall price also depends on the window style and material. Sliding windows and basic aluminium frames are usually more affordable, while awning windows, casement windows, and double-glazed options cost more due to improved insulation and durability. Across Australia, total supply and installation costs can range roughly from $150 to $1,500 per square metre, depending on specifications.
4) Factors That Affect Installation Cost
Several factors influence how much you will pay for installation. These include window size, frame material, glazing type, property access, and whether structural changes are required. Installations on upper floors or in hard-to-reach areas also increase labour costs. In many cases, labour can account for 30% to 50% of the total project cost, especially in renovation work.
5) Labour & Extra Charges
Labour charges in Australia usually range from $40 to $90 per hour, depending on the installer’s experience and job complexity. Additional costs may include removing old windows, sealing gaps, adjusting frames, and finishing work like plastering or painting. These extra tasks can significantly affect the final price, especially in older homes or renovation projects.
