Retrofit existing frames rather than replacing them to save 40–60%. Do the whole house at once for volume discounts. Choose standard double glazing over acoustic unless noise is a specific issue. Check government rebates and energy efficiency incentives. Compare at least three quotes from accredited glaziers.

Check online reviews on Google and trade platforms. Confirm the installer holds relevant licences and accreditations for your state or territory. Ask whether they carry public liability insurance. Request a written quote that itemises labour and materials separately. Confirm the warranty terms for both the glass units and the installation work. Ask to see examples of recent completed projects.
