Cost Considerations to Keep in Mind When Replacing Your Current Windows with Aluminium Windows
Upgrading your windows is one of the smartest home improvement projects you can undertake. Not only does it improve the look of your home, but it also impacts energy efficiency, security, and long-term durability.
Aluminium windows have become increasingly popular in South Africa, thanks to their sleek design, low maintenance, and ability to withstand harsh weather conditions. But before you take the plunge, it’s important to understand the costs involved.
Replacing your current windows with aluminium is an investment, and being aware of the financial considerations upfront will help you budget wisely and avoid unexpected expenses.
Understanding the True Cost of Aluminium Windows
When looking at the cost of aluminium windows, it’s worth noting that “cost” doesn’t just mean the purchase price. When it comes to aluminium windows, the overall expense is shaped by several factors, including installation, long-term maintenance, and even the potential savings you’ll enjoy over the years.
Looking at the full picture helps homeowners make a smarter decision – one that balances upfront investment with durability, performance, and return on value.
Here are the main cost considerations every homeowner should keep in mind when making the switch to aluminium windows.
1. Initial Purchase Price of Aluminium Windows
The most obvious cost to consider is the purchase price of the windows themselves. In general, aluminium windows are more affordable than solid wood alternatives, while still offering excellent strength and durability.
Wooden windows, particularly those crafted from hardwoods, tend to sit at the top of the price range because of the raw material costs and the craftsmanship involved.
Aluminium window prices will vary depending on:
-
The size of the window frames – larger frames naturally cost more.
-
Standard vs. custom designs – bespoke shapes or unusual sizes increase the price.
-
The type of finish – powder coating is the most common and cost-effective, while anodised and woodgrain finishes generally cost more.
-
Extra features – options like double or triple glazing, or integrated blinds between panes, add to the overall cost.
While solid wood windows may bring a warm, traditional charm, they typically require more maintenance and can have a shorter lifespan if not cared for properly.
Aluminium, by contrast, offers long-term cost savings due to its low maintenance, modern thermal efficiency, and durability of 40+ years. This makes aluminium a cost-effective choice for homeowners who want a balance of style, performance, and value.
2. Installation Costs
Window replacement is not just about buying frames; it is also about professional installation. Skilled labour is needed to ensure that the windows are properly fitted, insulated, and sealed to prevent drafts, leaks, or structural issues.
Factors that can affect installation costs include:
-
The number of windows being replaced
-
The difficulty of removing the existing windows
-
Accessibility (for example, higher floors or tricky angles may cost more)
-
Special structural requirements, such as widening or reinforcing openings
Pro tip: Always ask for a detailed installation quote so you can see exactly what’s covered.
3. Energy Efficiency Savings
One of the biggest advantages of aluminium windows is their energy efficiency. When fitted with double glazing and thermal breaks, aluminium frames help regulate indoor temperatures, keeping your home cooler in summer and warmer in winter.
While you might pay more initially for energy-efficient upgrades, these features can save you money in the long term through:
-
Lower heating and cooling costs
-
Enhanced resale value of your property
Think of energy efficiency as an investment, not just a cost.
4. Long-Term Maintenance Costs
Unlike wood, aluminium doesn’t warp, rot, or require frequent repainting. Its low-maintenance nature means you’ll save money on upkeep over time. However, there are still a few small costs to consider:
-
Occasional cleaning with mild soapy water to remove dirt and dust
-
Periodic inspections to check for seal wear and tear
-
Touch-ups on surfaces if scratched
These minor expenses are minimal compared to maintaining wooden windows, making aluminium a cost-effective choice in the long run.
5. Additional Features and Customisations
Customising your aluminium windows will impact the overall cost. Some popular add-ons include:
-
Tinted or reflective glass for privacy and UV protection
-
Double or triple glazing for maximum insulation
-
Soundproofing features if you live near a busy road or urban area
-
Unique colours or finishes to match your home’s aesthetic
While these upgrades increase costs, they also enhance comfort, functionality, and property value.
6. Potential Structural Adjustments
In some cases, replacing old windows with aluminium ones may require modifications to your walls or frames. For example, if your existing window openings don’t match the size of your new aluminium windows, resizing or reinforcing may be necessary.
These additional adjustments can increase labour costs, so it’s worth factoring them into your budget from the start.
7. Return on Investment (ROI)
While the upfront cost of aluminium windows may seem high, the return on investment makes them worthwhile. Here’s why:
-
Aluminium windows have a lifespan of 20-25 years with minimal upkeep
-
They enhance your home’s look and feel, and property value
-
Energy savings accumulate over time
-
They provide stronger security than many alternatives
By weighing short-term costs against long-term savings, you’ll see that aluminium windows are a smart financial decision.
Final Thoughts
Replacing your current windows with aluminium windows is a valuable investment that enhances both your home’s beauty and performance.
