Cost of Sliding Glass Doors (2026): Full Price Breakdown

The cost to install a sliding door in Australia is divided into three main components: sliding door supply and material costs, installation labour costs, and glass type and glazing costs. Each component varies depending on the door size, frame material, glass specification and complexity of the installation.

Cost Category	Material, Installation or Glass Type	Estimated Cost per m² (AUD)
Supply & Materials	Standard aluminium frame and door system	$250–$450
Supply & Materials	uPVC sliding door system	$300–$600
Supply & Materials	Timber sliding door system	$400–$800
Supply & Materials	Sliding tracks, rollers and standard hardware	$30–$100
Supply & Materials	Premium handles and locking hardware	$50–$150
Installation Labour	Standard replacement in an existing opening	$100–$200
Installation Labour	New installation in a prepared opening	$150–$300
Installation Labour	Large or multi-panel sliding door installation	$200–$400
Installation Labour	Pocket sliding door installation with additional wall work	$250–$400
Glass & Glazing	Standard clear glass	$30–$60
Glass & Glazing	Toughened safety glass	$95–$220
Glass & Glazing	Laminated safety glass	$130–$200
Glass & Glazing	Standard double-glazed glass unit	$150–$350
Glass & Glazing	Low-E double glazing	$220–$470
Glass & Glazing	Acoustic or premium performance glazing	$300–$680
Estimated Total	Combined supply, installation and glazing costs	$410–$2,130

These are indicative component ranges, not a fixed installed price. Some suppliers include glazing in the door package, so check what is included in each quote to avoid double-counting costs.

1. Sliding Door Supply and Material Costs

Sliding door supply costs depend on the frame material, door design, dimensions and quality of the sliding mechanism. Aluminium is a common choice for Australian homes, while timber and premium frame systems can cost more.

Sliding Door Material or Component	Estimated Cost per m² (AUD)
Standard aluminium frame and door system	$250–$450
uPVC sliding door system	$300–$600
Timber sliding door system	$400–$800
Sliding tracks, rollers and standard hardware	$30–$100
Premium handles and locking hardware	$50–$150

The figures are indicative budgeting estimates and may vary by manufacturer and product specification. Hardware costs may already be included in the supplied door system.

What affects material costs?

• Frame material: Aluminium is generally a cost-effective option, while hardwood and premium systems can increase the price.
• Door dimensions: Larger doors require more framing material and may need heavier-duty tracks and rollers.
• Hardware quality: Heavy-duty rollers, upgraded locks and premium handles can increase the total supply cost.
• Customisation: Non-standard dimensions, special finishes and multi-panel configurations typically cost more than standard systems.

2. Sliding Door Installation Labour Costs

Installation labour covers fitting the door, aligning the frame, installing tracks and rollers, adjusting the panels and checking that the door operates correctly. Labour costs depend on whether the installer is replacing an existing door or creating a new opening.

Installation Type	Estimated Labour Cost per m² (AUD)
Standard replacement in an existing opening	$100–$200
New installation in a prepared opening	$150–$300
Large or multi-panel sliding door installation	$200–$400
Pocket sliding door installation with additional wall work	$250–$400

These per-square-metre figures are planning estimates rather than standard industry rates. Installers may charge per door, per hour or as a fixed project price. For reference, Australian cost guides report carpenter and builder rates of approximately $90–$120 per hour, depending on the job and location.

What affects installation labour costs?

• Existing opening: Replacing a door in a suitable existing frame is generally simpler than installing a new system.
• Structural modifications: Altering walls, lintels or openings can add significant labour and building costs.
• Door weight and size: Large glass panels may require additional installers or lifting equipment.
• Removal and disposal: Removing an old door, repairing surrounding surfaces and disposing of materials can increase the installation price.

3. Sliding Door Glass Type and Glazing Costs

Glass selection is another important factor in the cost of installing a sliding door. Single glazing is generally more affordable, while double glazing, Low-E coatings and specialised safety glass can increase material costs.

Glass Type	Estimated Glass Supply Cost per m² (AUD)
Standard clear glass	$30–$60
Toughened safety glass	$95–$220
Laminated safety glass	$130–$200
Standard double-glazed glass unit	$150–$350
Low-E double glazing	$220–$470
Acoustic or premium performance glazing	$300–$680

These figures are indicative glass supply prices, not complete installed door prices. Actual costs depend on thickness, dimensions, processing, frame compatibility and supplier pricing.

How different glazing options affect the cost

• Standard clear glass: A lower-cost option for suitable applications, subject to applicable safety requirements.
• Toughened safety glass: Designed to provide safety benefits in appropriate applications and commonly used in glazed doors.
• Laminated glass: Contains an interlayer that helps hold fragments together if the glass breaks.
• Double glazing: Uses two panes separated by a sealed gap to improve thermal and acoustic performance.
• Low-E glazing: Uses a special coating to help reduce heat transfer, potentially improving energy efficiency.

Glass selection must suit the door system and comply with applicable Australian glazing and building requirements. The cheapest glass is not necessarily suitable for every door location.
