How much do new windows cost in Adelaide? Real 2026 ranges

How much do new windows cost in Adelaide?

Standard replacement windows in Adelaide cost $4,000–$12,000 per opening fitted in 2026. Double-glazed replacements typically run $8,000–$25,000 per opening. Full new-build window packages on a typical four-bedroom Adelaide home land $25,000–$80,000, with premium uPVC or architectural aluminium pushing past $120,000 on bigger or more considered builds.

Window pricing has more variables than most homeowners expect. The same opening can cost $4,500 or $14,000 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:

1. The frame itself. Aluminium, uPVC, timber, and steel sit at different price points — typically a 1× / 1.4× / 1.6× / 2× progression respectively for equivalent sizes.
2. The glazing. Single, double, or triple glazing — and within double, whether it’s standard, low-e, argon-filled, or laminated. Each layer adds 20–40% to the glazing line.
3. The hardware. Locks, hinges, winders, security ironmongery — usually 8–15% of the frame-and-glazing total.
4. 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”.
5. 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.
6. 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	$1,500–$3,500	Most common; salt-rated for coastal
uPVC	$1,800–$4,200	Premium European spec; growing fast in SA
Timber casement	$2,200–$4,800	Heritage-sympathetic; western red cedar
Timber double-hung sash	$2,500–$5,500	Heritage detail; restoration available

These are fitted prices — they include removal, reinstatement, and patching.

Double-glazing cost in Adelaide

Adding double glazing to the equation roughly doubles the glazing line and adds 30–60% to the per-opening fitted price. In practice:

Configuration	Per opening fitted
Aluminium double-glazed	$2,500–$5,500
uPVC double-glazed	$3,500–$7,500
Timber double-glazed (casement)	$3,800–$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 20–40% cheaper than bespoke.
• BAL-FZ exposure. Bushfire flame zone certification adds 30–60% to the frame-and-glazing total.
• Heritage detail. Custom timber sash with traditional cogs and weights runs 60–120% higher than modern equivalent.
• Acoustic glazing. Required near busy roads or airport flight paths; adds 25–40%.
• 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
• Direct supply for builders — owner-builders working with us through the builder-priced channel save 10–18%

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.
