How Much Does It Cost to Replace Your Home Windows?

Have your windows begun to rattle in the wind or let in just a little too much of that cold winter air? Perhaps they have become cloudy, broken, or simply out of style? Regardless of the reason, you might be asking yourself, "How much does it really cost to get new windows?”

Window replacement is not just about aesthetics; it is more about comfort, safety, and the ability to save money in the long term. If a window is correctly installed, it can keep your home cooler in the summer and warmer in the winter, with the added benefit of saving you money on your power bills.

In this blog, we will cover everything you need to know about the price of window replacement, materials, installation costs, and how to find reliable local tradies to do the job right. Let’s begin now.

How Much Does Window Replacement Cost?

The costs of replacing a window in Australia will average between $300 and $1,200 per window for standard- and moderate-sized windows, including materials and installation. The cost varies considerably depending on the number and type of windows you’re getting replaced.

For smaller standard-sized windows, the window replacement cost could drop to $250–$400 each. For larger, custom-sized windows, the cost could range from $350 to $1500 each. Let’s dig deeper into what actually affects these costs.

1. What Affects Window Replacement Cost in Australia?

No two houses are the same, nor are two window jobs the same price. Here are the key factors affecting your total costs: 

• Window Style – Basic single-hung or sliding windows are typically the cheapest. Bay, awning, or casement styles will typically be more expensive due to greater material and complexity of fitting. 

• Number of windows – By replacing a larger number of windows at once, you may see a lower per window cost, because your window trades can save time on removal and installation in one job. 

• Size and shape – Installing standard-sized shapes is typically easier and therefore cheaper to establish. Odd-shaped/sized arches and larger panels take more time and care to establish. 

• Glazing type – Single-glazed windows will be the cheapest option. Double or triple glazing adds insulation but also adds to the cost. 

• Access – Upper floor windows or windows in areas you can't easily access add to the labor hours and price! 

• Location in Australia – Pricing varies slightly depending on where you live; generally, the labor in Sydney to replace a window would be a little more than in a regional town.

2. Factors Affecting Window Replacement Price?

Let's get a closer look at these cost drivers, particularly from the perspective of an Australian homeowner. 

• Labor Costs - Generally, tradies charge between $50 and $120 per hour, depending on the complexity of the job and where you live in Australia. This charge generally includes the removal of the old frame, preparation, fitting, sealing, and cleaning up afterward. 

• Material Options - Aluminum is a durable and cost-effective option when it comes to material. Timber looks premium, but it can be expensive over time to maintain. uPVC is gaining popularity as a low-maintenance and durable option. 

• Customization - If you are looking for a specific design, tint, or frame finish, then expect to pay a little or a lot extra, depending on what is involved. 

• Energy Ratings - Energy-rated glass and insulated frames will cost you more but could save you long-term or ongoing energy bills. 

• Size of the Project - Replacing all the windows in your house at once will cost you more, but the cost per window will reduce due to overall labor and material efficiencies.

2. Tips to Save on Window Replacement Costs

You do not have to sacrifice quality for savings. Here are a few practical ideas that every Australian homeowner can apply to minimize the overall price:

• Replace Windows in Batches – By swapping out several windows at the same time, you can lower the overall labor costs. 

 

• Stay with Standard Sizes – Custom windows are a good idea, but they also cost more. Stick with standard sizes (where possible) to minimize costs.

• Mix & Match Material – Use premium materials on visible areas (e.g., on street-facing windows) and mixed materials in places that are mostly hidden.

• Rebates for Energy – Some local councils and energy programs offer rebates for energy-efficient windows.

• Collect Quotes – Do not simply agree to the first quote you receive. Make it a point to collect as many estimates from reputable tradies as possible before considering which is the most appropriate quote.

• Off-Season Planning – Trade people are generally less busy during late autumn or early spring and can offer you better pricing during the off-season.

Selecting a trusted professional is just as essential as choosing the right window. Let’s look at the points below to find the right tradie:

• Check the License and Insurance – Only work with licensed tradies and check their liability coverage.

• Ask About Experience – An experienced installer understands how to safely and effectively install different materials and structures.

• Check the Reviews and references – You can learn a lot from previous customers about a newer business by checking the reviews.

• Request a written quote – Always make sure you are quoted for the total price. Whether it’s removal, labor costs, or materials, get it all included!

• Service or materials warranties – A reputable tradesperson would offer a warranty on their service or materials.

Taking small steps along the way ensures that your investment is going to skilled tradespeople who will do it right the first time!

How long does replacing a window take?

Can I replace just one window, or should I do all at once?

You can absolutely replace just one window if only one is damaged or leaking. There’s no rule saying you need to do them all at once.
