How Much Does It Cost to Install a Glass Door in Australia?

The best remedy is to add a glass door into your home to add more sunlight and an open space. Glass doors make your house appear modern, link outside and inside, and even increase the value of your home.
But before you start, it’s important to know the sliding door installation cost and what can change the price.

Average Cost of Glass Door Installation in Australia

The cost of glass door installation in Australia usually ranges from $1,000 to $4,500. This includes both the door and professional installation. The final price depends on the design, size, and materials.

Here is a simple guide for common glass doors:
Door Type Approximate Cost
Sliding glass doors $1,000 – $2,500
Double sliding patio doors $2,000 – $3,500
Aluminium sliding doors $1,500 – $3,000
Double glass doors $2,500 – $4,000
Sliding double glazed doors $3,000 – $4,500
These are estimates. Your price may change depending on location, brand, and job complexity.

What Affects the Cost of Installing a Glass Door

Key Factors That Influence the Cost of Installing a Glass Door in Your Home

1. Type of Door

Different types of glass doors come at different prices. Sliding glass doors are the most common and affordable. Double sliding patio doors and double glass doors cost more but give a wider, more stylish look.
Sliding double glazed doors are pricier but worth the price should you desire better insulation and also less noise. They ensure a comfortable house throughout the year, particularly in the mixed weather in Melbourne.
2. Frame Material
The frame material has a big effect on the final price. Aluminium sliding doors are very popular in Australia because they’re light, strong, and easy to maintain.
Timber frames are beautiful and classic and require a lot more attention and re-painting as the years pass by. uPVC is also a great choice as they are energy efficient and withstand heat, rain and salt air.

3. Glass Type 

The cost of glass changes depending on the style and safety features. Standard clear glass is the cheapest, but it doesn’t help much with temperature control.
Safety or toughened glass is more expensive and compliant to the Australian safety standards and provide superior protection. Dual-glanced glass is an intelligent solution to save energy bills and minimize external noise impacts.

4. Size and Custom Design

The larger the door, the higher the price. Custom shapes, wide openings, or unique designs also add to your glass sliding doors prices.
Colored or clouded glass, ornaments on the panels, or special locks will also add to your price on a glass door but may add to the security and beauty.

5. Labour and Installation

The cost of labour may vary based on the severity of the job. It may be approximately $400 to $800 to replace old sliding doors.
In case you require a new opening cut into a wall, the price of replacing sliding doors or adding some will be expensive due to additional construction.

Awkward locks, handles, or tracks may also require some additional cost that can cost between $100 and $300 dollars. Depending on the location, there would be delivery charges.

DIY vs Professional Installation

You can consider putting up a sliding glass door and saving on the expenses. But there is the wisest course in professional installation.

Professionals make sure:

Replacement of sliding glass doors typically costs between $1,500 to $3,500 in terms of size, materials, and style. New aluminium sliding doors or double-glazed sliding doors can make it a lot more comfortable, secure and cost-effective – not to mention updating the appearance of your home.

Sliding Glass Door Installation Melbourne – Frequently Asked Questions (2026)

How much does a glass door cost to install in Melbourne in 2026?

For a standard aluminium sliding glass door in Melbourne, installed supply-and-install, expect $1,500–$2,500 for single glazing and $2,800–$3,800 for double glazing in a standard single-panel configuration. Double sliding patio doors (two panels) range from $2,500–$3,500 for single glaze and $4,000–$5,500 for double glaze. These figures cover the door unit, labour, removal of the existing door, and track and hardware fitting. Structural wall work (new openings or lintel replacement) is quoted separately. Clearcut Glass provides free measure and quote for all glass door installations across Melbourne.

What is the cost to replace just the glass panel in a sliding door, without replacing the whole frame?

If the existing aluminium frame is structurally sound, glass-panel-only replacement is the most cost-effective option. A standard toughened single-glaze replacement panel for a 2100×2100mm sliding door costs $380–$650 supply and install. Double glazed IGU replacement in the same size costs $950–$1,350. The glazier removes the broken panel, measures the opening, orders a toughened replacement cut to size, and re-installs with new seals — typically completable within one to two days depending on glass lead time.

How much do aluminium sliding doors cost in Australia, and what affects the price?

Aluminium sliding doors in Australia range from $1,500–$3,000+ for a standard single-panel unit, supply and install. The main price drivers are frame section quality (standard vs architectural grade), thermal-break specification (adds $300–$600 but significantly improves energy performance in Melbourne's climate), powder coat colour (standard colours are cheaper than custom), glass type (single vs double glazed), panel size, and roller and hardware grade. Entry-level aluminium sliding doors in standard white with single glazing represent the most affordable option; thermal-break aluminium with double glazing and heavy-duty rollers represents the premium end of the range.

Is toughened glass required for sliding door replacement in Melbourne?

Yes — toughened safety glass compliant with AS/NZS 2208 is mandatory for all sliding door panels under Australian Standard AS 1288. This requirement applies to both glass-panel-only replacement and full door unit replacement, regardless of what was in the door previously. The replacement glass must also carry the AS/NZS 2208 compliance mark etched into the glass. Any glazier quoting standard float glass for a sliding door panel in Melbourne is quoting non-compliant work — confirm in writing that your replacement glass will be toughened and marked before accepting any quote.

Is it worth upgrading to double glazed sliding doors in Melbourne?

For most Melbourne homes, double glazed sliding doors deliver meaningful comfort and energy benefits, particularly in west and north-facing rooms that experience significant summer heat gain, or in homes with poor heating performance in winter. The upfront premium over single glazed doors is $1,000–$1,500 per door. Energy bill savings vary by home and usage, but in Melbourne's climate the thermal performance improvement is substantial enough that the upgrade is commonly worthwhile when the door is already being replaced. The case is strongest when combined with a thermal-break aluminium frame, which prevents the frame itself from acting as a heat bridge around the double glazed panel.

What additional costs should I budget for when replacing a sliding glass door in Melbourne?

Beyond the door unit supply and install, budget for: removal and disposal of the existing door ($100–$200 if not included in your quote — confirm this upfront); upgraded rollers or lock hardware if the existing hardware is worn ($80–$300 depending on specification); structural work if the opening size is changing or the lintel needs assessment ($800–$2,500+ depending on wall type); and wall reveal repair — plastering, rendering, or recladding — if the new door frame size differs from the old one. Clearcut Glass includes old door removal and disposal in our standard quotes and confirms what is and is not included in writing before any work begins.

How long does sliding glass door installation take in Melbourne?

A straightforward like-for-like single sliding door replacement — removing the old unit and installing a new one in the same opening — typically takes 3–5 hours with a two-person team. A double-panel or stacker door installation takes a full day. If structural work is required (new opening or lintel), that work precedes the door installation and is scheduled separately. For glass-panel-only replacement in an existing frame, allow 1–2 hours on-site once the replacement glass has been cut and delivered. Clearcut Glass confirms the expected timeline at the time of quote.
