Is it time to replace your old, draughty or noisy windows? APS Double Glazing is Melbourne’s trusted window replacement specialist, upgrading homes across Melbourne and regional Victoria with premium uPVC double glazed windows designed for Australian conditions.

Why Choose Professional Window Replacement?

Replacing your windows is about more than updating how your home looks. Professional window replacement solves common problems that affect your daily comfort and energy bills. Old or inefficient windows can lead to:

High energy costs – Heat loss in winter and heat gain in summer
Outside noise – Traffic, neighbours, and street sounds disrupting your peace
Condensation and mould – Moisture build-up on cold glass surfaces
Security concerns – Weak, outdated locking systems
Draughts and discomfort – Cold spots and temperature fluctuations

Upgrading to high-performance double glazed replacement windows delivers immediate improvements in comfort, efficiency and value. Homeowners across Melbourne choose window replacement to create quieter, more comfortable homes while reducing ongoing energy costs and maintenance requirements.

What Does Window Replacement Involve?

Window replacement can refer to a few different approaches depending on the condition of your existing windows.

In some cases, it involves removing the entire window and installing a new system. In others, it may be possible to replace only the glass or repair components such as seals, hinges or locks.

The most common options include:

Glass-only replacement where frames are still in good condition
Hardware or seal repairs for operational issues
Retrofit installations using the existing opening
Full-frame replacement for older or deteriorating windows

The right approach depends on the condition of the frame, the level of performance required, and long-term goals for the home.

Should You Repair or Replace Your Windows?

Not every window needs to be replaced. In some cases, a targeted repair may be enough.

Repair may be suitable when:

The frame is structurally sound
Issues are limited to seals, locks or hardware
You are looking for a shorter-term solution

Replacement is often worth considering when:

Frames are warped, corroded or deteriorating
Windows leak or cause ongoing discomfort
Multiple issues are present at once
Improved insulation or noise reduction is a priority

If several components are failing at the same time, replacing the window may provide a more reliable long-term outcome.

Frequently Asked Questions (FAQs)

1. How long does window replacement take?

The time required for window replacement depends on how many windows are being replaced and how accessible they are. In many homes, installation can be completed over one to two days once the windows are ready. Each window is usually replaced individually, which helps keep disruption manageable while ensuring proper fit, sealing and performance.

2. How do I know if my windows need replacing?

You may need window replacement if you notice draughts, outside noise, condensation between panes, difficulty opening or closing windows, or rising heating and cooling costs. Ageing frames, especially older aluminium or timber ones, can also lose efficiency over time. If your home feels uncomfortable despite using heating or cooling, your windows could be a contributing factor.

3. Will double glazing increase my property value?

Double glazing can add to your property’s appeal by improving comfort, energy efficiency and noise reduction. Many buyers now look for homes with modern, low-maintenance features, and upgraded windows may make your property more attractive compared to similar homes with older glazing. While value increases vary, double glazing is often seen as a long-term improvement rather than a cosmetic upgrade.

4. Do you remove and dispose of old windows?

Yes, old windows are typically removed as part of the window replacement process. This includes taking out existing frames and glass and disposing of them responsibly. Proper removal helps protect surrounding walls and finishes and allows new windows to be installed and sealed correctly for long-term performance.

5. What maintenance is required for uPVC double glazed windows?

uPVC double glazed windows require very little maintenance compared to timber or older aluminium frames. Occasional cleaning with mild soapy water is usually enough to keep frames looking good. There is no need for painting, sanding or corrosion treatment, which makes them well-suited to Australian conditions and busy households.

 Trustindex verifies that the original source of the review is Google. We recently had double glazing windows installed, and the entire experience was outstanding from start to finish. From our initial enquiry to the final installation, the team were professional, attentive, and incredibly efficient. They took the time to measure everything perfectly and ensured the installation went smoothly. The quality of the windows is fantastic, and we’ve already noticed a difference in both temperature and sound insulation in our home. I highly recommend APS to anyone looking for top-notch service and quality products.

 Trustindex verifies that the original source of the review is Google. We were having severe problems with our double glazed back door installed by another company. The guarantee had run out and so had their willingness to repair it. We contacted APS with the view of having the door replaced. Andy inspected the offending door and quickly found the problem. After a short adjustment and a few cups of tea the door had been repaired. We were delighted with the outcome but more so that there is someone like Andy that is honest. We will certainly be using APS when we need more windows replaced. Thanks Andy.

Choosing the Right Windows for Your Home

Before moving ahead with a window replacement project, it can be helpful to understand the different options available. The right combination of glazing, materials and window styles can influence comfort, performance and long-term suitability for your home.

Understanding Your Glazing Options

While frame material plays a role, glazing has a significant impact on comfort and performance.

Common options include:

Double glazing – helps reduce heat transfer and improve insulation
Laminated glass – may assist with noise reduction and added security
Toughened glass – often used where safety requirements apply
Low-E glass – designed to improve thermal performance
Acoustic glazing – suited to homes near busy roads or urban areas

The right combination depends on your home’s location, orientation and how each room is used.

Comparing Window Materials

There is no single “best” window material. The right option depends on the home, budget and performance requirements.

uPVC – low maintenance, strong insulation and well suited to double glazing
Aluminium – durable and slim, often used in modern designs
Thermally broken aluminium – improved insulation compared to standard aluminium
Timber – often chosen for character homes and traditional finishes
Composite systems – designed to balance strength, performance and maintenance

Material choice should consider climate, maintenance expectations and the overall design of the home.

Choosing the Right Window Style

Different window styles suit different spaces depending on ventilation, access and layout.

Awning windows – suitable for ventilation, even in light rain
Casement windows – allow strong airflow and wide openings
Sliding windows – practical where space is limited
Double hung windows – often suited to traditional homes
Tilt and turn windows – allow internal cleaning and flexible ventilation
Fixed windows – ideal for light and views where airflow is not required

A well-planned design considers how each room is used, along with airflow, cleaning access and overall comfort.

Cost, Value and Choosing the Right Company

Window replacement costs can vary depending on window size, style, glazing type and access requirements. While double glazing is often seen as a premium upgrade, many homeowners consider it a long-term investment due to improved energy efficiency, lower ongoing maintenance and added property appeal.

Value is more than just price. As a window replacement company, we focus on local manufacturing to European-quality standards, experienced installers and strong warranties to support long-term performance. This approach helps ensure proper installation, consistent insulation and reliable durability in Australian conditions.

Window replacement costs can also be influenced by several factors, including:

Frame material and glazing type
Window size, shape and opening style
Hardware, finishes and additional features such as flyscreens
Access to the property, particularly for upper-storey installations
Structural adjustments to existing openings
Removal and disposal of old windows

Some homeowners may also choose to replace windows in stages, focusing first on areas that have the greatest impact on comfort, such as bedrooms or street-facing rooms.

Considerations for Australian Homes

Window performance can vary depending on location and property type.

Climate and orientation – north, west and south-facing windows can behave differently
Coastal environments – materials and hardware may need to withstand salt exposure
Bushfire zones – additional compliance requirements may apply
Strata or body corporate – approvals may be required for some properties
Heritage homes – design and appearance may need to be maintained
Safety glazing – certain areas may require compliance with Australian Standards

These factors are important to consider when selecting the right window system.

Common Mistakes to Avoid

When planning a window replacement project, it helps to avoid some common pitfalls:

Replacing windows without checking if repair is sufficient
Focusing on frame material without considering glazing performance
Assuming all double glazing performs the same
Choosing window styles without considering ventilation or access
Comparing quotes without reviewing inclusions and installation quality
Expecting windows alone to solve all energy efficiency issues

A well-informed approach can help ensure the final result performs as expected.

Experience the Difference New Windows Make

Replacing old or inefficient windows delivers lasting improvements in comfort, noise reduction and energy efficiency. With the right double glazed system in place, your home becomes quieter, safer and easier to maintain.

If you’re considering home window glass replacement or a full window upgrade, APS Double Glazing provides professional window replacement services using systems designed for Australian conditions. Our locally manufactured uPVC double glazed windows are installed by experienced specialists to ensure reliable, long-term performance.
