How Much Do New Windows Cost in Adelaide? (2026)

How much do new windows cost in Adelaide?
Single-glazed replacement windows in Adelaide typically cost $700–$5,500 per opening fitted in 2026, depending on size and frame. Double-glazed replacements typically run $1,500–$8,500 per opening. Full new-build window packages on a typical four-bedroom Adelaide home land around $18,000–$95,000, with architecturally-designed builds running substantially higher.
Window pricing has more variables than most homeowners expect. The same opening can cost under $2,000 or well over $8,000 depending on the frame material, the glazing spec, the heritage overlay, and the access conditions. This guide breaks down what’s actually driving the number on your quote.
What’s in a window quote
A real Adelaide window quote covers six cost layers:
- The frame itself. Aluminium, uPVC, timber, and steel sit at different price points — rising roughly in that order for equivalent sizes.
- The glazing. Single, double, or triple glazing — and within double, whether it’s standard, low-e, argon-filled, or laminated. Each step up adds to the glazing line.
- The hardware. Locks, hinges, winders, security ironmongery — a smaller but real share of the total.
- Removal and reinstatement. Taking out the existing window cleanly, reinstating brick or render externally, and patching the architraves internally — this is the “fitted” part of “fitted price”.
- Access and site conditions. First-floor windows over a stepped landscape cost more to install than ground-floor sliders. Heritage detail adds time. Strata or commercial access adds documentation. Overhanging trees over the install elevation can need Adelaide tree pruning before the fitter arrives — a pruning visit before install can make the day run more smoothly.
- Planning and certification. BAL-rated systems, heritage approvals, and energy-rating documentation are real cost lines on the projects that need them.
Replacement window costs (single-glazed, fitted)
| Frame material | Per opening fitted | Notes |
|---|---|---|
| Aluminium | $700–$3,500 | Most common; salt-rated for coastal |
| uPVC | $1,500–$4,200 | Premium European spec; growing fast in SA |
| Timber casement | $1,400–$4,800 | Heritage-sympathetic; western red cedar |
| Timber double-hung sash | $2,200–$5,500 | Heritage detail; restoration available |
These are fitted prices — they include removal, reinstatement, and patching. The low end of each range reflects small openings such as single awning windows.
Double-glazing cost in Adelaide
Adding double glazing raises the glazing line and the per-opening fitted price. In practice:
| Configuration | Per opening fitted |
|---|---|
| Aluminium double-glazed | $1,800–$5,500 |
| uPVC double-glazed | $1,500–$7,500 |
| Timber double-glazed (casement) | $2,800–$8,500 |
| Premium uPVC triple-glazed | $5,500–$11,000 |
Retrofit double-glazing — adding a second pane to an existing timber-frame window where the frame can accept it — runs $1,800–$4,000 per opening. Aluminium frames generally can’t be retrofitted; full replacement is usually the right call.
Full-home new-build window packages
A typical four-bedroom Adelaide build runs 12–20 window openings totalling 60–110 square metres of glazing. Realistic 2026 ranges:
- Standard aluminium single-glazed: $18,000–$32,000 supplied and fitted
- Aluminium double-glazed: $32,000–$65,000
- uPVC double-glazed (premium European): $50,000–$95,000
- Architectural mixed (timber sash + aluminium curtain wall): $80,000–$160,000
These are realistic mid-range numbers. Architecturally-designed homes with feature glazing, multi-pane sliders, and bespoke detail can run substantially higher.
What pushes prices up
- Custom sizes. Standard sizes (made to common modules) are cheaper than bespoke.
- Bushfire (BAL) requirements. The higher BAL levels, especially BAL-40 and BAL-FZ, add significantly to the frame-and-glazing total.
- Heritage detail. Custom timber sash with traditional cords and weights costs considerably more than a modern equivalent.
- Acoustic glazing. Worth considering near busy roads or flight paths; adds to the glazing cost.
- Multi-storey access. Scaffolding requirements can add $2,000–$8,000 per project.
What can push prices down
- Standard sizes ordered as a package
- Material consolidation (everything aluminium, or everything uPVC) avoids supplier setup charges
- Off-season install (May–August) — quieter time of year, sharper pricing
The realistic budget
For an Adelaide homeowner planning a full-home window upgrade in 2026, budget $35,000–$80,000 for a meaningful aluminium-double-glazed retrofit, or $50,000–$110,000 for premium uPVC double glazing. Plan a 4–8 week supply lead time and a 5–7 day install window.
