Double Glazed Windows Cost for Melbourne Builders
A practical cost guide for Melbourne builders estimating double glazed windows - tender allowances, supply-only vs install, and where schedules lose money.
Send a schedule or book a measure — local aluminium manufacture for Melbourne builders.
Builders searching double glazed windows cost in Melbourne are usually mid-estimate, mid-variation or mid-argument with a client who assumed single glazing. This guide is written for trade estimating - not glossy homeowner marketing.
What to allow at tender
For residential aluminium with standard double glazing, many Melbourne builders allow a mid-band figure per opening and refine once the schedule is frozen. Under-allowing for Low-E or acoustic glass is the classic profit leak.
- Standard DG aluminium window (supply-only): build a contingency above bare clear IGU rates
- Doors and large sliders: price separately - they are not window rates
- Upper-level install access: scaffold and two-person handling change the game
- Powder-coat colour changes after extrusion starts = rework cost
Where quotes go wrong
- Schedule says 'DG' with no U-value / SHGC - energy consultant upgrades later
- Rough openings change after frame order
- Site wants staged delivery but quote assumed one drop
- Heritage or BAL requirements appear after the price is locked
