Estimate an exterior entry door by the measured opening, selected pre-hung unit, threshold details and surrounding finish. Keep product, fitting and weather closure visible rather than quoting a bare door price. The worked one pre-hung entry door example uses measured metric quantities and fictional AUD amounts; check the actual site and supplier information before quoting.

THE SHORT ANSWER

Estimate an exterior entry door by the measured opening, selected pre-hung unit, threshold details and surrounding finish. Keep product, fitting and weather closure visible rather than quoting a bare door price.

This Australian walkthrough uses a fictional one pre-hung entry door in Adelaide, South Australia. The matching exterior entry door replacement estimate example (https://quicklyestimates.com/en-au/samples/exterior-door-replacement-estimate/) shows the same item quantities and amounts in an app-exported PDF. Measure your own site and replace the example rates before issuing a client quote.

1. Identify the replacement assembly

Record opening dimensions, swing, sill and hardware selection. A slab-only job differs from this pre-hung replacement in both product and labour.

For this example, the agreed starting scope is: Replace one pre-hung exterior entry door in an existing suitable opening. Include door allowance, removal, installation, weatherstrip and threshold allowance, hardware fitting, interior trim touch-up allowance and disposal. Opening enlargement and structural repair excluded. A change to a listed surface, product or access assumption should trigger a revised line or allowance.

2. Inspect the existing opening

The sample assumes suitable framing and adjacent finishes. Hidden deterioration or enlargement requires a separate inspected scope before proceeding.

3. Detail weather and hardware work

List threshold, weatherstrip and handle fitting responsibilities. Clarify which components come with the selected unit so allowances do not duplicate supplier packages.

4. Define finish and disposal

State whether casing, paint, exterior trim and old-door disposal are included. The touch-up allowance here is limited, not a full wall or cladding refinish.

Worked exterior entry door replacement calculation

Two checkable lines from the example are 1 each × A$336.00 = A$336.00; 1 each × A$1,470.00 = A$1,470.00. The full 7-line estimate totals A$3,696.00 with the demonstration tax input at 0%. The amount is a fictional scenario, not an Australian market rate or a recommended selling price.

Material purchasing and installed quantities may differ. For your own estimate, use the actual takeoff, supplier prices, labour plan, access and disposal requirements. Decide how overhead, profit and the applicable tax treatment affect your final quote; do not copy the example's zero tax setting.

Before you share the estimate

- Measure opening, swing and threshold.
- Confirm selected unit and hardware.
- Inspect framing and adjacent finishes.
- Define trim and disposal limits.

Scope boundary in this example: No opening enlargement, structural repair, cladding replacement, full repainting or specialty security system integration.

Confirm the client details and location, item descriptions, measured units, total and validity date. If opening up the work reveals a different condition, document the changed scope and price before proceeding.

Common questions about exterior entry door replacement

Is an exterior door the same scope as an interior door?

No. Threshold and weather closure details need explicit consideration along with the selected assembly and opening.

Does the price include painting?

Only where stated. This example has a trim touch-up allowance but no complete door or wall repaint.
