Pricing guide

Costs vary mainly with whether you choose like-for-like glass, manufactured insulated double-glazed units, or a full supply-and-fit window. Double-glazed and full-unit work typically carry higher material allowances and modest labour uplift for handling or frame adaptation. Access, the condition of existing frames, and any need for scaffolding or hazardous-material handling can also affect quotes.

  • Glass type and performance

    Higher-performance or double-glazed insulated units usually have greater material cost and require more careful handling.

  • Supply scope: glass vs full unit

    Supplying a complete window unit typically increases material allowance and may add carpentry and finishing tasks compared with a glass-only replacement.

  • Frame condition and carpentry needs

    If existing frames are damaged or require adaptation for new glazing, carpentry work is often needed and enlarges the job scope.

  • Access, height and equipment required

    Jobs at height or with restricted access may require scaffolding or an elevated work platform, which typically increases complexity.

  • Manufacture lead time and handling

    Custom or manufactured insulated glass units often have longer lead times and may affect scheduling and overall timing.

Frequently asked questions

How long will an upgrade usually take?
Timing depends on the scope: like-for-like glass swaps are usually quicker, while manufactured double-glazed units or full supply-and-fit installations often take longer and may be staged. Lead times for custom units can also extend the overall schedule.
Do glaziers need a licence for this work?
This type of glazing and window replacement work requires a licensed glazier. You should ask the tradesperson to confirm they hold the appropriate licence for the work.
Will my frames need carpentry or repairs?
If frames are structurally sound, a like-for-like replacement is typically straightforward. If frames are damaged or you're fitting a full window unit, carpentry, sealing and finishing work is often required and may be quoted separately.
Do insulated double-glazed units cause delays?
Manufactured insulated units often have longer manufacture and delivery times and may also need frame rebate work, so they typically add time to the project. Providers usually plan for fabrication and delivery when scheduling installation.
Is the SureQuote estimate a quote, and why can a tradie's quote be different?
No. Your estimate is a guide price for a typical job that matches your answers. A tradie prices your actual job in their quote, once they've seen things like access, condition, materials and the full scope. Read the full answer
What happens after I submit my job, and how many tradies will contact me?
We email you your estimate and a link to your job. Up to 3 local tradies can take it and contact you to quote; only they get your name, phone and email, and you choose who to hire, if anyone. Read the full answer
Is it free to get quotes, and does the tradie's fee raise my price?
Yes, getting quotes is free and you don't have to hire anyone. Tradies pay us a capped fee to take your job, and we set it before they quote, so nothing is added to your quote. Read the full answer
Can I add photos to my job?
Yes. Add up to 10 photos in the chat after you give your contact details, or later from the job in Hire, and tradies see them before they take the job. Read the full answer
Do I have to hire one of the tradies?
No. Getting quotes is free, you're never obliged to hire anyone, and you pay only the tradie you choose to hire. Read the full answer
Does SureQuote check tradies' licences and insurance?
We collect each business's ABN, licence, insurance and warranty details and keep them as up to date as we can, so you can see them in one place on its profile. We don't guarantee them, so always check the licence yourself on the relevant licence register before you hire. Read the full answer
