When undertaking a home improvement project, the cost of windows often represents a significant portion of the overall budget. Whether you are replacing existing windows, upgrading for energy efficiency, or installing new windows during a renovation or build, it is important to understand the costs involved.
In Australia, the cost of windows can vary significantly based on several factors such as size, material, glazing options, installation requirements, and the brand or supplier. This article provides a comprehensive breakdown of these factors to help homeowners make informed decisions.
Factors That Influence The Cost Of A Window
Type Of Window
The type of window is one of the primary determinants of cost. Here are some common window types and their associated costs:
- Fixed Windows: These are non-opening windows that are often the most affordable option. They typically cost between $150 and $400, depending on size and material.
- Sliding Windows: A popular choice in Australian homes, sliding windows can range from $200 to $600 per unit.
- Awning Windows: Known for their functionality and weather resistance, awning windows cost between $300 and $700.
- Double-Hung Windows: These versatile windows, which open from both the top and bottom, are priced between $400 and $800.
- Casement Windows: Hinged at the side and known for their elegance, casement windows usually range from $400 to $900.
- Bay or Bow Windows: These larger, more complex installations can cost anywhere from $1,500 to $3,000 or more.
Material Of The Window Frame
The material used for the window frame plays a critical role in determining both the cost and the overall aesthetic appeal of the window. Common materials include:
- Aluminium: A popular, durable, and cost-effective option, aluminium window frames generally cost between $150 and $1,000, depending on size and type.
- Timber: Timber frames are aesthetically pleasing and excellent for insulation but are more expensive, ranging from $300 to $2,000.
- uPVC (Unplasticised Polyvinyl Chloride): Known for its energy efficiency and low maintenance, uPVC frames typically cost between $250 and $1,500.
- Composite: A blend of timber and aluminium, composite frames offer durability and aesthetic value, with costs ranging from $400 to $2,500.
Glazing Options
The type of glazing significantly impacts the overall cost of the window. Modern homeowners are increasingly opting for energy-efficient glazing options, which can reduce heating and cooling costs in the long run. Common glazing options include:
- Single Glazing: The most basic and affordable option, with costs starting at $50 per square metre.
- Double Glazing: Provides better insulation and noise reduction but costs more, typically ranging from $150 to $300 per square metre.
- Triple Glazing: Offers superior insulation and noise reduction but is the most expensive option, costing between $250 and $400 per square metre.
- Low-E (Low-Emissivity) Glass: A specialised coating that improves energy efficiency. Low-E glass typically adds $50 to $150 per square metre to the cost.
- Tinted or Frosted Glass: Ideal for privacy and UV protection, these options generally cost an additional $30 to $100 per square metre.
Size And Customisation
Standard-sized windows are generally more affordable than custom-made options. Customisation adds to the cost because it requires specialised manufacturing. For example:
- A small standard window may cost around $150 to $400.
- A larger or custom-shaped window can cost upwards of $1,000.
- Oversized or floor-to-ceiling windows may exceed $2,000 per unit.
Installation Costs
Installation costs vary based on the complexity of the job, the number of windows being installed, and the location of the property. Standard installation fees in Australia range from $150 to $400 per window. However, more complex installations, such as those involving large or awkwardly positioned windows, may cost between $500 and $1,000 per unit. Additional costs may apply for removing old windows, reinforcing walls, or meeting specific energy efficiency requirements.
Brand And Supplier
The brand or supplier you choose can also impact the cost of your windows. Reputable brands with a proven track record of quality and durability may charge a premium, but their products often come with extended warranties and better performance. Local suppliers may offer competitive pricing while importing windows can increase costs due to shipping and import duties.
Tips To Save On Window Costs
- Compare Quotes: Obtain multiple quotes from different suppliers and installers to ensure competitive pricing.
- Opt for Standard Sizes: Choosing standard-sized windows can significantly reduce costs compared to custom-made options.
- Consider Energy Efficiency: While energy-efficient options like double glazing may have a higher upfront cost, they can reduce long-term energy bills and increase the value of your home.
- Plan for Bulk Purchases: If you need multiple windows, purchasing them in bulk can often result in discounts.
- Choose the Right Material: Balance aesthetics, durability, and budget when selecting the frame material. Aluminium frames are affordable and durable, while uPVC offers better insulation at a mid-range price.
- DIY Where Possible: If you have the skills, installing windows yourself can save on labour costs. However, ensure you meet building codes and safety standards.
- Timing: Some suppliers offer discounts during off-peak seasons or promotional periods, so timing your purchase strategically can help you save.
Hidden Costs To Watch Out For
When budgeting for new windows, consider the following potential additional costs:
- Removal of Old Windows: This can add $50 to $200 per window.
- Structural Modifications: Reinforcing walls or resizing window openings can significantly increase costs.
- Permits and Approvals: Depending on your local council regulations, you may need to budget for permits, which can cost a few hundred dollars.
- Delivery Fees: For large or heavy windows, delivery fees can range from $50 to $300.
- Maintenance Costs: Timber frames require regular maintenance, such as painting or sealing, which adds to long-term expenses.
Conclusion
The cost of windows in Australia varies widely based on type, material, size, glazing, and installation. On average, homeowners can expect to pay anywhere from $150 for a basic fixed aluminium window to over $3,000 for a large custom bay window.
By understanding the factors that influence window costs and following tips to save, you can make choices that align with your budget and design goals. Always consider long-term benefits such as energy efficiency and durability when selecting windows, as these can contribute to cost savings and increased home value over time.
