Replacing the windows in your home can significantly improve both its aesthetic appeal and energy efficiency. Whether you’re looking to upgrade old, inefficient windows or simply want a new look, it’s important to understand the costs involved.
The price of replacing windows varies depending on a variety of factors, including the type of window, materials used, labour costs, the size of the project, and the location of your property. This guide will explore the different cost factors associated with window replacement in Australia and provide insight into how much you can expect to pay.
Type Of Window
The type of window you choose is one of the most important factors in determining the cost. There are several types of windows to choose from, each with varying price points.
Single-Hung Windows:
A single-hung window has a fixed upper sash and a movable lower sash. These are generally the most affordable option and cost around $200 to $500 per window.
Double-Hung Windows:
With both the upper and lower sashes capable of moving, double-hung windows offer more flexibility. Prices for double-hung windows range from $300 to $800 per window, depending on the brand and material.
Casement Windows:
Casement windows are hinged at the side and open outward, offering a unique look and great ventilation. These windows typically cost between $400 and $1,200 per unit.
Sliding Windows:
Sliding windows are designed to slide horizontally and are a popular choice for modern homes. They generally cost around $400 to $1,000 per window.
Awning Windows:
Hinged at the top, these windows open outward like an awning and are often used in bathrooms or smaller rooms. Awning windows cost between $400 and $800 per unit.
Bay Or Bow Windows:
These are larger, more intricate window designs that extend outward from the wall, creating a curved appearance. Bay or bow windows are more expensive, typically ranging from $1,000 to $3,000 or more per window, depending on size and complexity.
Material Of The Window
The material of the window frame plays a significant role in the overall cost. Common materials include:
Timber (Wood):
Timber frames are a classic choice, offering a traditional look and good insulation properties. However, timber frames require regular maintenance (such as painting and sealing) to prevent deterioration. The cost for timber-framed windows generally starts at $500 and can go up to $2,500 or more, depending on the size and design.
Aluminium
Aluminium frames are durable and require minimal maintenance. They are also more affordable than timber. The cost for aluminium-framed windows typically ranges from $350 to $1,500 per unit.
uPVC (Vinyl)
uPVC windows are becoming increasingly popular due to their energy efficiency and low maintenance requirements. They are often the most cost-effective option, with prices ranging from $300 to $1,500 per window, depending on size and quality.
Fibreglass:
Fibreglass windows are highly durable, energy-efficient, and low maintenance. They are more expensive than uPVC or aluminium, with prices starting at $800 per window and reaching up to $3,000 for larger or more complex designs.
Glazing Options
The type of glazing you choose will have a significant impact on the overall cost. Glazing refers to the glass used in the window and can vary based on the number of panes, the type of coating, and its energy efficiency.
Single Glazed:
Single-glazed windows are the most basic option, consisting of one pane of glass. They are generally the least expensive but provide poor insulation and are not ideal for energy efficiency. The cost for single-glazed windows is generally lower, ranging from $200 to $700 per window, depending on the frame material.
Double Glazed:
Double-glazed windows are much more energy-efficient than single-glazed options. They consist of two panes of glass with a layer of air or gas in between, which helps reduce heat transfer. The cost of double-glazed windows is higher, typically ranging from $500 to $1,500 per unit.
Triple Glazed:
Triple-glazed windows are designed for maximum insulation and energy efficiency. These windows have three layers of glass, making them suitable for colder climates. The cost for triple-glazed windows generally starts at $800 per window and can exceed $2,500 for larger or custom-made units.
Additional Consideration
Size And Number Of Windows
Naturally, the size of the windows will impact the overall cost of replacing them. Larger windows require more materials and labour, thus increasing the price. Similarly, the number of windows being replaced will also influence the overall cost. Replacing multiple windows in a single project may lead to some cost savings, as labour costs can be more efficient when bundled together.
Labour Costs
Labour costs for window replacement vary depending on the location, complexity of the installation, and the experience of the tradespeople involved. In Australia, window installation typically costs between $75 and $150 per hour for a qualified tradesperson. The time required for installation depends on the type and number of windows being replaced, but as a rough estimate, you can expect to pay anywhere between $100 to $500 per window for installation.
Additionally, if your windows require special installation considerations, such as structural changes or dealing with old and difficult-to-remove windows, labour costs may be higher. For example, the cost of removing and disposing of old windows could range from $50 to $200 per window, depending on the complexity of the removal.
Window Accessories
Additional accessories can also increase the cost of window replacement. Common window accessories include:
Window Screens:
If you require window screens for ventilation, expect to pay anywhere between $50 and $150 per screen.
Shutters And Blinds:
Custom shutters or blinds can add significant cost to your window replacement project. Prices for these accessories typically range from $100 to $1,000 per window, depending on the material and design.
Security Features:
For windows with security screens or reinforced glass, the cost may increase by around $200 to $500 per window.
Window Design And Customisation:
Custom-made windows with intricate designs or unusual sizes will cost more than standard windows. Some manufacturers offer bespoke services for windows with unique shapes, colours, or finishes.
Energy Efficiency:
If you opt for energy-efficient windows, such as low-emissivity (Low-E) glass or windows with gas fills, the initial cost may be higher. However, you will likely save money on energy bills in the long run, making this a worthwhile investment.
Location And Supply Chain Costs
The location of your property can influence both the cost of materials and the cost of installation. For example, window replacement in urban areas like Sydney or Melbourne may be more expensive due to higher labour rates and delivery charges. On the other hand, in more remote or regional areas, shipping costs and the availability of specialised contractors may increase costs as well.
Estimated Cost For Replacing Windows
To give you an idea of what you might expect to pay for window replacement, here is an approximate breakdown based on a few common scenarios:
- Standard Single-Hung Window Replacement: If you are replacing a single-hung window (1.2m x 1.5m) with a basic aluminium frame and single glazing, the total cost could be around $300 to $500 per window, including installation.
- Double-Hung Window Replacement with Double Glazing: A mid-range double-hung window (1.2m x 1.5m) with double glazing in an aluminium frame could cost between $600 and $1,200 per window, including installation.
- High-End Window Replacement: For a large, custom-designed timber-framed casement window (1.5m x 2m) with triple glazing and additional energy-efficient coatings, the price could easily exceed $2,500 to $3,500 per window, including installation.
Conclusion
The cost of replacing windows in Australia can vary significantly depending on a wide range of factors, including the type of window, materials used, size, and number of windows to be replaced. On average, you can expect to pay anywhere between $300 and $3,500 per window, depending on your specific requirements.
While the initial cost of window replacement can seem significant, it’s important to consider the long-term benefits, such as improved energy efficiency, increased property value, and enhanced comfort.
By selecting the right type of window and glazing option for your needs, you can make a smart investment that pays off over time.Before making a decision, it’s always a good idea to get multiple quotes from reputable window suppliers and installers to ensure you’re getting the best value for your money.
Frequently Ask Question
What Is The Difference Between Upvc And Timber Window Frames?
uPVC (unplasticized polyvinyl chloride) frames are a low-maintenance, cost-effective option that offers excellent insulation properties. They are resistant to rot and do not require frequent painting. Timber frames, on the other hand, provide a classic aesthetic and great insulation but require regular maintenance, such as painting or sealing, to prevent deterioration. Timber windows tend to be more expensive than uPVC.
Can I Install Windows Myself, Or Do I Need A Professional?
While it is possible to install windows yourself, it’s generally recommended to hire a professional installer. Window installation requires precision and experience to ensure proper sealing, insulation, and safety. Mistakes in installation can lead to drafts, leaks, or structural damage, which could end up costing more in repairs in the long run.
How Do I Know If My Windows Need To Be Replaced?
Signs that your windows may need to be replaced include drafts, condensation between panes, difficulty opening or closing windows, or visible damage like cracks or rotting frames. If your windows are old and inefficient, it may be worth considering an upgrade to improve energy efficiency and overall comfort. A professional window installer can assess your windows and recommend whether replacement is necessary.
