THE ESTIMATING ANSWER
For four cracked wall sections, start with a defined scope and measurement basis. Record crack length, patch area, depth and whether movement is active. Separate backing repair, plaster materials and final decoration expectations. Price the listed tasks separately and state the condition that would require a revision: Loose background or continued movement can change the repair method.
This guide follows four cracked wall sections in Launceston, Tasmania. 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
Repair four local plaster wall defects on sound backgrounds, including opening, patching, finish coats and sanding to paint-ready condition. Record crack length, patch area, depth and whether movement is active. 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: Record crack length, patch area, depth and whether movement is active. 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
Separate backing repair, plaster materials and final decoration expectations. This example has 7 distinct lines, including protection and defect mapping, loose plaster removal, backing and bonding allowance. Use actual supplier prices and labour inputs for a customer job; the displayed amounts are fictional document inputs.
Choose before pricing: Separate backing repair, plaster materials and final decoration expectations. The fixture separates protection and defect mapping, loose plaster removal and backing and bonding allowance rather than hiding all work in one figure.
3. Sequence the work and handoffs
Resolve the cause of movement or damp before patching and allow required drying stages. 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: Resolve the cause of movement or damp before patching and allow required drying stages. Note which stage needs access, a selected product or another trade before the next stage can be priced confidently.
4. Set a change boundary
Loose background or continued movement can change the repair method. The example excludes structural movement repair, damp treatment or full-wall painting. Record the discovery, agree the revised work and update the estimate before adding it to the job.
Change trigger: Loose background or continued movement can change the repair method. Record the revised task and quantity before it changes the amount your client sees.
Review the Australian job
Check access, substrate, drainage and product delivery at the property. Record weather and site conditions that affect the work, and confirm any design or approval requirements for the real scope.
The patch application line uses 4.27 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 Launceston, Tasmania or another location.
Worked project calculation
The paired PDF has 7 cost lines. For example, Loose plaster removal is 4 hours × A$79.48 = A$317.92; Patch application is 4.27 m² × A$280.00 = A$1,195.60. Each amount comes from the stated quantity and unit rate, so you can trace the arithmetic back to the job scope.
| Work item | Quantity | Unit rate | Amount |
|---|---|---|---|
| Protection and defect mapping | 1 job | A$195.08 | A$195.08 |
| Loose plaster removal | 4 hours | A$79.48 | A$317.92 |
| Backing and bonding allowance | 1 job | A$252.88 | A$252.88 |
| Patch application | 4.27 m² | A$280.00 | A$1,195.60 |
| Finish and feather edges | 10 hours | A$86.70 | A$867.00 |
| Return sanding visit | 1 job | A$209.53 | A$209.53 |
| Clean-up and paint-ready check | 1 job | A$130.05 | A$130.05 |
| Illustrative total | A$3,168.06 | ||
Adding every exact-cent line gives A$3,168.06. 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
Repair four local plaster wall defects on sound backgrounds, including opening, patching, finish coats and sanding to paint-ready condition.
Outside this example: No structural movement repair, damp treatment or full-wall painting.
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.
