How Much Do Aluminium Windows Cost in Centurion? 2026 Price Guide

How Much Do Aluminium Windows Cost in Centurion? 2026 Price Guide

If you are planning a new home, renovation, residential development or commercial construction project in Centurion, Gauteng, one of the first questions you are likely to ask is: How much do aluminium windows cost?

The short answer is that there is no single price for an aluminium window. The final cost depends on the size and style of the window, aluminium profile, glass specification, colour or finish, hardware, quantity required and whether installation is included.

For budgeting purposes, current South African and Pretoria-area pricing guides provide useful indications. Standard aluminium windows can range from approximately R1,300 to R2,500 for a 900mm × 900mm window before installation, while a 1,500mm × 1,500mm aluminium window can range from approximately R3,100 to R4,400 before installation. Current Centurion-specific market listings also show installation and larger or more specialised window systems can increase the overall project cost considerably.

These figures should be treated as budgeting guidelines rather than fixed prices, because every aluminium window project is different.

What Determines the Cost of Aluminium Windows in Centurion?

1. Window Size

The size of the opening is one of the most obvious factors affecting price.

A small bathroom or kitchen window will require considerably less aluminium and glass than a large living-room window, office façade or architectural opening.

For example, current South African pricing guides indicate approximately:

Window sizeIndicative supply price900mm × 900mmR1,300 – R2,5001,500mm × 1,500mmR3,100 – R4,400900mm × 600mm side-hungR1,100 – R1,900

These are indicative market figures and can change according to the specification and supplier.

For contractors and developers, measuring the total number and sizes of openings before requesting quotations is therefore important when preparing an accurate project budget.

2. The Type of Aluminium Window

The style of window you choose will also affect the price.

Common aluminium window options include:

• Sliding windows
• Side-hung or casement windows
• Top-hung or awning windows
• Fixed windows
• Tilt-and-turn windows
• Custom or architectural window systems

A basic fixed window generally costs less because it has fewer moving components. Sliding, tilt-and-turn and specialised windows require additional hardware and manufacturing, which increases the cost.

Current Pretoria-area pricing, which is relevant to the wider Centurion/Tshwane market, places standard sliding windows around R1,500–R3,000 before installation, while casement windows are approximately R1,200–R2,500, depending on specification.

3. The Glass Makes a Significant Difference

The aluminium frame is only one part of the finished window.

The type and thickness of glass can significantly affect the quotation.

Depending on the project, you may require:

• Standard clear glass
• Toughened safety glass
• Laminated glass
• Tinted or solar-control glass
• Double glazing

For residential projects, the correct glass specification can improve safety, comfort and energy performance. For commercial and industrial projects, glazing requirements may be influenced by the building's design, location and intended use.

This is particularly important when comparing quotations. Two companies may quote very different prices for what appears to be the same size window simply because they are using different glass and frame specifications.

4. Does the Price Include Installation?

This is one of the most important questions to ask when comparing aluminium window prices in Centurion.

A price advertised online may be for supply only, while another quotation may include manufacturing, delivery, removal of existing windows, installation, sealing and finishing.

Current local and Pretoria-area pricing sources show installation can add approximately R1,500–R2,500, depending on the project and installation requirements. Other market guides show installation costs can vary significantly depending on the number, size and complexity of the windows.

For a new construction project, installation may also need to be coordinated with brickwork, plastering, waterproofing and other trades.

Aluminium Window Cost for a New Development

For contractors and developers, pricing individual windows is only part of the calculation.

A development might require dozens or even hundreds of windows in different configurations. In this situation, the most useful approach is to prepare a window schedule showing:

• Opening number
• Width and height
• Window type
• Number of panes
• Opening configuration
• Glass specification
• Aluminium colour
• Hardware requirements
• Quantity required
• Installation requirements

This allows suppliers to quote against the same specification and makes it much easier to compare quotations accurately.

Don't Compare Quotes on Price Alone

The cheapest aluminium window quotation is not necessarily the best value.

When comparing suppliers, contractors and developers should check whether each quotation includes the same:

Aluminium profile + glass + hardware + finish + delivery + installation + seals + warranties.

Comparing the total specification rather than simply the bottom-line figure prevents the common problem of comparing two products that are not actually equivalent.

Are Aluminium Windows Expensive in Centurion?

Aluminium windows can be more expensive upfront than some basic window alternatives, but their durability, low maintenance requirements, modern appearance and design flexibility make them a popular choice for South African residential and commercial construction.

For a homeowner, the right aluminium window can be a long-term investment in the property.

For a contractor, consistent quality and reliable installation can help reduce callbacks and remedial work.

For a developer, the correct window specification can contribute to the overall appearance, functionality and marketability of the development.

How to Get an Accurate Aluminium Window Quote in Centurion

Online price guides are useful for establishing a preliminary budget, but they cannot replace a project-specific quotation.

To obtain an accurate price, provide your aluminium window supplier with as much information as possible, including the window measurements, quantities, preferred styles, glass requirements, colour and whether installation is required.

For larger residential, commercial or construction projects, a site assessment and detailed window schedule can provide a much more accurate costing.
