How Much Does a Custom Aluminium Window Cost?

The cost of a custom aluminium window depends on size, glazing, and design complexity. On average in Melbourne:

• Small custom aluminium windows: $450 – $900

• Medium-sized custom windows: $900 – $1,800

• Large or architectural windows: $2,000 – $5,000+

Factors that influence price include:

1. Size & Shape – Unusual shapes (arched, round, oversized) add to manufacturing costs.

2. Glazing Type – Single-glazed windows are cheaper, but double or triple glazing provides superior insulation and noise reduction.

3. Frame Finish – Powder-coated colours, anodised finishes, or thermal breaks increase costs.

4. Custom Features – Flyscreens, acoustic glass, or integrated blinds all add to the price.

For example, a Melbourne homeowner installing four large double-glazed custom aluminium windows might expect a total cost between $6,000 – $10,000, depending on design and installation requirements.

At EZ Windows, we specialise in tailored solutions, ensuring every window is manufactured to fit perfectly and perform at the highest level.

Does Bunnings Do Custom Windows?

Bunnings offers a range of standard-sized aluminium windows, but they do not typically supply custom-made aluminium windows. Their products are designed for DIY renovators or builders working with standard openings.

Limitations of Bunnings windows include:

• Fixed sizes – Not ideal for non-standard or older homes in Melbourne where openings may vary.

• Limited glazing options – Most are single-glazed and not energy efficient.

• Basic frames – Often designed for budget renovations rather than long-term durability.

If you need custom aluminium windows Melbourne, a specialist supplier like EZ Windows is your best option. We provide exact sizing, premium finishes, and professional installation — ensuring the job is done right the first time.

How Much Does It Cost to Install an Aluminium Window?

The cost to install an aluminium window in Melbourne depends on the complexity of the project. On average:

• Basic installation (standard replacement): $250 – $450 per window

• Complex installation (structural changes, large frames, double glazing): $600 – $1,200+ per window

Installation costs cover:

• Removal of old windows

• Preparation of openings

• Installation of the new aluminium frame

• Sealing, waterproofing, and finishing touches

At EZ Windows, our expert installers can complete most projects in a single day, minimising disruption. For example, one Melbourne customer had four-panel sliding windows installed in just 5 hours, thanks to our streamlined process.

How Much Do Aluminium Windows Cost?

Aluminium windows are available in a wide range of sizes and styles. Standard costs in Australia are:

• Small fixed aluminium window: $150 – $400

• Sliding aluminium window: $400 – $1,200

• Awning aluminium window: $500 – $1,500

• Double-glazed aluminium window: $800 – $2,500

• Large custom aluminium window: $2,000 – $5,000+

While aluminium windows are generally more expensive than timber or uPVC, their durability, low maintenance, and modern aesthetics make them a cost-effective long-term investment.

What Is a Cheaper Alternative to Aluminium Windows?

If aluminium windows don’t fit your budget, there are alternatives:

1. uPVC Windows – Typically cheaper and energy efficient, but less durable in Melbourne’s hot summers.

2. Timber Windows – Affordable upfront, but require ongoing maintenance and repainting.

3. Standard Off-the-Shelf Windows – Available at Bunnings or hardware stores, but limited in sizing and design flexibility.

That said, aluminium remains the best value over the long term because of its strength, resistance to warping, and superior lifespan. A cheaper window may save money now but cost more in repairs and replacements later.

Can I Install Aluminium Windows Myself?

Technically, you can install aluminium windows yourself — especially smaller units purchased from hardware stores. However, DIY installation comes with risks:

• Incorrect fitting can cause water leaks, drafts, and poor energy efficiency.

• Structural issues may arise if the frame isn’t properly aligned.

• Warranty voids – Many manufacturers won’t cover warranties if windows aren’t professionally installed.

• Safety hazards – Large double-glazed panels are heavy and dangerous to handle without the right equipment.

For these reasons, most Melbourne homeowners choose professional installation. At EZ Windows, our expert team ensures every custom aluminium window is installed safely, securely, and to industry standards.
