Installing aluminium windows in your home is a fantastic investment that can enhance curb appeal, improve energy efficiency, and offer lasting durability. This guide provides a comprehensive overview of the costs associated with aluminium window installation in South Africa, helping you budget effectively and make informed decisions.

‍

Aluminium Windows Installation Prices In South Africa

Aluminium window installation costs in South Africa typically range from R1,500 to R15,000 or more per window, depending on various factors such as size, style, glass type, and the complexity of the installation.

‍

Factors Affecting Aluminium Window Installation Prices

The cost of installing aluminium windows can vary significantly based on several key factors:

‍

Window Size and Type

Larger windows and custom designs will naturally cost more due to increased material and labour requirements. Different window styles also come with varying price tags.

• Casement Windows: These hinged windows open outward and generally range from R1,500 to R4,000+ per window.
• Sliding Windows: These windows slide horizontally and typically cost between R2,000 and R5,000+ per window.
• Awning Windows: Hinged at the top, opening outwards from the bottom, these are priced from R1,500 to R4,000+ per window.
• Fixed Windows: Non-opening windows, offering a sleek look, generally cost between R1,000 and R3,500+.
• Tilt and Turn Windows: These versatile windows can tilt inward for ventilation or open fully, ranging from R2,500 to R5,500+.

‍

Glass Options and Thickness

The type of glass significantly influences the overall cost.

• Single-pane glass is the most affordable, but offers less insulation.
• Double-glazed windows provide better insulation and soundproofing, leading to higher upfront costs but potential long-term energy savings. Expect a 10-30% increase for energy-efficient options.
• Safety glass (toughened or laminated) will also increase the price.

‍

Frame Finish and Colour

While standard aluminium finishes are typically included, custom colours or specialized finishes like wood-grain may incur an additional 5-15% on the cost.

‍

Installation Complexity

The difficulty of the installation plays a crucial role in pricing.

• Accessibility: If the windows are difficult to access (e.g., on higher floors, or requiring scaffolding), labour costs will increase.
• Removal of old windows: If old frames need to be removed and disposed of, this will add to the overall cost.
• Structural modifications: Any necessary alterations to the wall opening to accommodate the new windows will also add to the complexity and cost. Expect a 20-50% variation based on site conditions.

‍

Number of Windows

Installing multiple windows at once might lead to a slightly lower per-window cost due to economies of scale for the labour.

Typical Costs for Aluminium Window Components

‍

Typical Materials Cost

The cost of the aluminium window unit itself varies widely based on size, type, and features.

• Small aluminium windows (e.g., 600mm x 600mm) can start from around R500 to R1,000.
• Medium-sized windows (e.g., 900mm x 900mm) typically range from R1,000 to R2,000.
• Larger windows (e.g., 1200mm x 1200mm) can be between R2,000 and R3,500.
• For very large or custom designs, prices can go up to R15,000 or more per unit.

‍

Typical Labour Cost

Installation labour costs for aluminium windows generally range from R1,500 to R2,500 per window. This can be influenced by the complexity of the job, the number of windows, and site accessibility. Some installers might charge per square meter, with rates ranging from R350 to R800 per square metre for standard windows.

‍

Breakdown of Specific Cost Values

• Call Out Fee (Not applicable to window installation directly, but common in other home services): For other services where a call-out fee might apply (like an emergency repair), this typically ranges from R350 to R650 during business hours.
• Emergency Fee (Not directly applicable to planned window installation, but for urgent repairs): For emergency situations that require immediate attention (e.g., a broken window needing urgent board-up), plumbers often charge an emergency call-out fee ranging from R500 to R1,000 hourly, or even a flat rate of R2,500 for urgent work excluding parts.
• After Hours Rate (Not directly applicable to planned window installation, but for urgent repairs): If an urgent repair is needed outside of standard working hours, the hourly rate can increase significantly, typically by 50-100% of the standard rate, potentially reaching R650 to R1,200 per hour for plumbing services.
• Cleaning or Disposal Fee: This typically applies to the removal and disposal of old window frames and any construction debris. It can be factored into the overall quote or charged separately. Rubble removal costs can range from R500 to R1,200 for a mini-load (1-2 cubic meters) of general construction debris. For larger volumes or specialized waste, costs will increase.

Frequently Asked Questions

How can I get an accurate quote for aluminium window installation?
The best way to get an accurate quote is to contact several reputable installers. Provide them with precise measurements, your preferred window styles, glass type, and details about the existing openings. An on-site assessment is vital for accurate pricing.

Does the type of glass significantly impact the cost?
Yes, absolutely. Single-pane glass is the most economical, while double glazing for improved insulation or specialized safety glass will significantly increase the material cost.

Are there different grades of aluminium for window frames?
While aluminium is generally durable, there can be variations in the thickness and quality of the profiles used, which can influence the cost and the window's overall strength and longevity.

Can I install aluminium windows myself to save money?
While it might seem appealing to save on labour costs, professional installation is highly recommended. Incorrect installation can lead to drafts, leaks, poor insulation, and even compromise the structural integrity of the window, costing more in the long run.

How long does aluminium window installation typically take?
The duration depends on the number and size of windows, and the complexity of the installation. A single standard window might take a few hours, while a full house replacement could take several days.

What affects the labour cost for installation?
Labour costs are influenced by the installer's experience, the complexity of the job (e.g., removal of old frames, structural adjustments), the accessibility of the work area, and the region in South Africa.

Will installing new aluminium windows increase my property value?
Yes, investing in high-quality, energy-efficient aluminium windows can increase your property's value, especially if they enhance the aesthetic appeal and improve energy efficiency, making your home more attractive to potential buyers.

Are aluminium windows maintenance-free after installation?
Aluminium windows are very low maintenance, but they are not entirely "maintenance-free." Occasional cleaning with mild soap and water is recommended to keep them looking good and ensure smooth operation of moving parts.
