How to price garage interior painting work in Australia

By Estimates editorial team · Published 2026-09-25 · Australia edition

This guide follows one clear single-bay garage in Albury, New South Wales. The matching itemised estimate and PDF show how the job brief becomes measured quantities and separate AUD amounts. The responsible role in this scenario is painter. Check the actual site, selected products, supplier figures and labour plan before issuing a client quote.

1. Define the measured job

Repaint sound garage walls and ceiling after minor preparation; exclude the floor and garage door. Measure walls and ceiling separately, noting shelves, exposed services and surface porosity. Record the measurements and existing condition in the estimate before turning quantities into line items. The scope should make clear why this is a separate project from a broader renovation or maintenance quote.

Measure for this job: Measure walls and ceiling separately, noting shelves, exposed services and surface porosity. Put that measured basis beside the relevant PDF lines so area, fitted length and product purchase quantities stay distinct.

2. Build a product and labour schedule

Choose wall and ceiling products and decide whether stain or bare-block primer is required. This example has 7 distinct lines, including area clearance and masking, wall cleaning and filling, primer allowance. Use actual supplier prices and labour inputs for a customer job; the displayed amounts are fictional document inputs.

Choose before pricing: Choose wall and ceiling products and decide whether stain or bare-block primer is required. The fixture separates area clearance and masking, wall cleaning and filling and primer allowance rather than hiding all work in one figure.

3. Sequence the work and handoffs

Confirm access to a cleared work area before washing, filling and coating. Show which task depends on access, a selected product or another trade. If that dependency is still open, label the price preliminary and identify the information needed before a firm quote.

Plan the handoffs: Confirm access to a cleared work area before washing, filling and coating. Note which stage needs access, a selected product or another trade before the next stage can be priced confidently.

4. Set a change boundary

Oil contamination or wet masonry changes preparation and product suitability. The example excludes garage floor coating, shelving removal or structural crack repair. Record the discovery, agree the revised work and update the estimate before adding it to the job.

Change trigger: Oil contamination or wet masonry changes preparation and product suitability. Record the revised task and quantity before it changes the amount your client sees.

Review the Australian job

Inspect the existing surface, access, product schedule and handoff conditions. Resolve unknown work and confirm any specialist requirements before giving a client a final quote.

The wall application line uses 48.31 m². Keep the site measurement and supplier's selling unit together; a material purchase allowance can differ from installed coverage. The amounts are fictional AUD inputs, not current prices for Albury, New South Wales or another location.

Worked project calculation

The paired PDF has 7 cost lines. For example, Wall cleaning and filling is 9 hours × A$59.28 = A$533.52; Wall application is 48.31 m² × A$27.00 = A$1,304.37. Each amount comes from the stated quantity and unit rate, so you can trace the arithmetic back to the job scope.

Adding every exact-cent line gives A$3,381.82. The PDF uses a 0% tax input only to make its fictional arithmetic visible. Confirm the GST treatment that applies to the actual job and set your own markup before sharing a client quote. A fictional rate is a document input, not a market quote or a recommended selling price.

Scope and pricing boundaries

Repaint sound garage walls and ceiling after minor preparation; exclude the floor and garage door.

Outside this example: No garage floor coating, shelving removal or structural crack repair.

Separate product allowances, supply, installation, disposal and any specialist work where the actual project needs them. If access or a hidden condition changes, document the affected scope and agree a revised price instead of silently extending the base amount.
