How Much Do Aluminium Windows Cost in Melbourne?
Straight answer: for a typical Melbourne home of 10 to 15 windows and doors, supply and install generally runs $20,000 to $50,000. A whole-home replacement on a 3 to 4 bedroom house typically lands between $20,000 and $80,000 depending on size, glazing and access. Anyone who quotes you a number without seeing your home is guessing. But you deserve real ranges before you talk to anyone, so here they are.

What drives the price
Number and size of openings
More windows, bigger windows, more cost. Large sliding doors and floor-to-ceiling glass cost more per opening than standard windows.
Glazing
Double glazing is the Melbourne standard for comfort and energy. Triple glazing adds roughly 20 to 30 percent on the glazing component and makes sense for busy roads or south-facing rooms.
Frame system
Standard aluminium is the entry point. Thermally broken frames (an insulating barrier inside the frame that stops heat passing through the metal) cost more and perform far better. Our SoTherm systems achieve U-values between 1.6 and 2.4, against around 6.0 for old single glazing. Lower is better.
Installation complexity
Ground floor with easy access is cheapest. Two-storey, heritage details and difficult access add labour.
Colour and finish
Standard powder coat colours are included. Premium and dual-colour finishes add a margin.
Replacement vs new build
Replacement costs more per window than a new build because the old window has to come out and the opening made good. For new builds and extensions we work from your plans and quote the full package, which is why builders and owner-builders get a tighter price per opening.
Is double glazing worth the money in Melbourne?
Yes, and Melbourne is exactly the climate it was made for. Cold winters, hot summers and temperature swings in a single day. Thermally broken double glazing cuts heat transfer at the frame and the glass, which shows up in your heating and cooling bills and in rooms that hold their temperature.

How much do aluminium windows cost in Melbourne?
For a typical home of 10 to 15 windows and doors, supply and install generally ranges from $20,000 to $50,000. Whole-home replacements on a 3 to 4 bedroom house typically range from $20,000 to $80,000.
How much extra is triple glazing?
Typically 20 to 30 percent more on the glazing component compared to double glazing. Worth it for noise on main roads; double glazing covers most Melbourne homes.
Is there a cheap option?
Standard aluminium frames with double glazing are the entry point. We do not sell single glazing for living spaces; it fails Melbourne's climate and current energy standards in most cases.
Do you charge for quotes?
No. Measure and quote are free, and the price we give you is fixed.
How long do new windows take?
Custom-made systems are typically manufactured over 10 to 12 weeks. We keep you updated through production rather than going quiet, and installation itself is usually days, not weeks.
Will I save on energy bills?
Thermally broken double glazing cuts heat transfer dramatically compared to single glazing (U-values of 1.6 to 2.4 versus around 6.0). Most clients notice rooms holding temperature immediately; bill savings depend on your home and usage.
