How Much Does Installing Aluminium Windows Cost in Auckland, New Zealand?

Aluminium windows are a popular choice for New Zealand homes due to their durability, low maintenance, and sleek, modern look. If you're considering upgrading your windows, here’s a breakdown of what aluminium window installation might cost and the factors influencing the final price.

Key Factors Affecting Aluminium Window Installation Costs

1. Window Size and Style
   Larger windows or complex styles, such as sliding or bi-fold windows, cost more than standard casement windows. For example:

   • Standard Aluminium Casement Window: $500 - $800 per window

   • Sliding Window: $800 - $1,200 per window

   • Bi-fold or Custom-sized Windows: $1,500 - $3,000 or more per window

2. Type of Glazing
   Double glazing is common for insulation and noise reduction in New Zealand but comes at a higher cost than single glazing. Here’s what to expect:

   • Single Glazing: Starting around $300 - $500 per square meter

   • Double Glazing: $400 - $700 per square meter

   • Triple Glazing: $700 - $1,000 per square meter (less common but available for high insulation needs)

3. Frame Quality and Finish
   High-quality aluminium frames with thermal breaks or powder coating for added durability and insulation will increase costs. A standard aluminium frame may cost around $500 - $700 per square meter, while premium finishes can add $100 - $300 per square meter.

4. Installation and Labour Costs
   Installation costs vary based on the complexity of the job and the number of windows. Installation charges range between $200 - $400 per window, though larger or high-up installations requiring scaffolding or more extensive framing work may add more.

5. Existing Window Removal and Disposal
   Removing old windows and disposing of them is usually a separate cost. Expect to pay around $100 - $200 per window for removal and disposal.

6. Additional Features
   Optional features like security screens, tinting, and insect screens can add to the total cost, typically $100 - $300 per window depending on the feature.

DIY vs. Hiring a Professional for Aluminium Window Installation

While installing windows yourself may save on labor costs, professional installation is recommended for ensuring weatherproofing, proper insulation, and structural safety. Professionals also help with proper sealing to avoid air and water leaks, which can lead to long-term damage.

Tips for Reducing Aluminium Window Installation Costs

1. Get Multiple Quotes: Compare quotes from reputable suppliers and installers to get a fair price.

2. Choose Standard Sizes: Custom-sized windows increase costs, so if possible, opt for standard sizes.
