Key takeaways
- Most window installation & replacement jobs in Australia land between A$600–A$20,000 — known locally as window replacement.
- Australian glazing must comply with AS 1288 and windows with AS 2047; bushfire-prone sites add BAL construction requirements for openings. Aluminium frames dominate the market, and double glazing is rapidly becoming the default under updated NCC energy provisions.
- Prices below are researched national ranges, updated July 2026 — not quotes.

What affects the price
- Job size and scope — bigger or more complex jobs move you up the ranges above.
- Access and condition — hard-to-reach areas, older properties or neglected maintenance add labour time.
- Materials and quality level — where materials are involved, the grade you choose often matters more than labour.
- Urgency — same-day or out-of-hours work usually carries a premium.
- Where you live — large metros in Australia typically run above the national range; smaller towns below it.
How to save
- Get at least three quotes and compare like-for-like scopes, not just totals.
- Be flexible on timing — off-peak slots are often cheaper.
- Bundle related tasks into one visit to spread call-out costs.
- Agree the scope in writing up front to avoid change-order surprises.
How to hire a window installation & replacement pro in Australia
- Confirm glazing complies with AS 1288 (safety glass in doors, low windows, bathrooms) and AS 2047 for window performance
- Check state licensing for the trade and value threshold (QBCC in QLD, Fair Trading in NSW)
- In bushfire-prone areas, confirm BAL-rated windows and screens as required
- For two-storey work, confirm scaffold/EWP costs are in the quote
- Ask about energy performance (WERS ratings) — single glazing is still common but double is becoming standard
- Get per-window pricing with disposal and making good included
Red flags
- Non-safety glass proposed in doors or low openings (AS 1288 breach)
- No BAL awareness in bushfire zones
- Unlicensed for the job value
- No ABN or written quote
- Big deposit without a manufacturing order confirmation

Frequently asked questions
Do new windows need planning permission or permits?
Like-for-like replacement is usually permit-free, but many places regulate windows through energy codes, safety-glass rules, and egress requirements for bedrooms — and heritage/conservation properties almost always need consent for changes. Your installer should know local rules; ask what paperwork you'll receive at completion.
Can windows be replaced in winter or bad weather?
Yes — pros replace one opening at a time so the house is never fully open, and cold-weather installation is routine in cold climates. Sealants and foams have temperature limits, so extreme cold or rain may shift a schedule, but winter is often the quieter, cheaper season to book.
How much does window replacement cost?
Windows are priced per opening: the unit itself (frame material, glazing spec, size) plus installation labour. A standard-size replacement in an existing opening is the base case; enlarging openings, upper-floor access, bay windows and heritage styles add meaningfully. Whole-house jobs get per-window discounts.
Why is my double glazing misted up between the panes?
The sealed unit has failed and let moist air in. The fix is usually replacing just the glass unit, not the whole frame — a fraction of full replacement cost. Widespread misting across many windows of the same age suggests the batch is failing and full replacement may be better value.
How long does window installation take?
Replacing a window in an existing opening takes 2-4 hours per window for an experienced crew — a whole house is usually 1-3 days. The wait is in manufacturing: made-to-measure windows typically take 2-8 weeks from survey to fitting.
What should a window installation quote include?
Per-window pricing with glazing spec, removal and disposal of old windows, making good internal reveals and external sealing, hardware, and warranty terms for both the unit (often 10 years) and the installation. Cheap quotes commonly exclude making-good — the messiest part.
What is double glazing and is triple glazing worth it?
Double glazing (two panes with a sealed gas gap) is the modern default. Triple adds insulation and noise benefits that matter most in cold climates and on noisy roads; elsewhere the extra cost rarely pays back. Spend first on installation quality and low-E coatings — a badly fitted triple-glazed unit performs worse than a well-fitted double.
Is double glazing standard in Australia?
It is now effectively standard in new builds under NCC 2022's 7-star energy provisions and common in replacements, especially in Melbourne, Canberra and Tasmania. In tropical QLD the priorities shift to shading, ventilation and cyclone/debris ratings rather than insulation.
