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 uses four cracked wall sections as a worked, fictional job. Its matching itemized estimate and PDF let you trace the advice to actual document lines. The role considered here is painter. Confirm the site conditions, product selections and your own costs before preparing 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.
Measurement basis: Record crack length, patch area, depth and whether movement is active.
2. Build a product and labor 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 labor inputs for a customer job; the displayed amounts are fictional document inputs.
Selections to confirm: Separate backing repair, plaster materials and final decoration expectations.
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.
Work sequence: Resolve the cause of movement or damp before patching and allow required drying stages.
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.
If the job changes: Loose background or continued movement can change the repair method.
Worked project calculation
The example line for loose plaster removal is 4 hours × $55.00 = $220.00. This line is one part of the complete 7-item estimate and uses a fictional unit rate.
The paired estimate has 7 separate lines. For this fictional job, multiply each quantity by its unit price and add the line amounts to get $2,193.00. The sample PDF uses these exact values, with tax and markup left at zero so the arithmetic is visible. This total is an illustration, not a regional price or an offer to perform the work.
| Cost line | Quantity | Unit price | Line amount |
|---|---|---|---|
| Protection and defect mapping | 1 job | $135.00 | $135.00 |
| Loose plaster removal | 4 hours | $55.00 | $220.00 |
| Backing and bonding allowance | 1 job | $175.00 | $175.00 |
| Patch application | 46 sq. ft. | $18.00 | $828.00 |
| Finish and feather edges | 10 hours | $60.00 | $600.00 |
| Return sanding visit | 1 job | $145.00 | $145.00 |
| Clean-up and paint-ready check | 1 job | $90.00 | $90.00 |
| Illustrative subtotal | $2,193.00 | ||
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.
Separately identify supplier allowances, labor, subcontracted work and site-specific risk where they apply. Before giving a selling price, decide how your own overhead, profit and any applicable tax will be handled. Do not copy the fictional rates into a real quote without checking your own measurements and supplier or subcontractor figures.
