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. The Kelowna, British Columbia worked example checks 7 CAD cost lines against the measured scope, with a C$3,034.00 illustrative subtotal before tax or markup.

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 a fictional project in Kelowna, British Columbia: Four cracked wall sections . Its matching estimate and PDF (https://quicklyestimates.com/en-ca/samples/plaster-wall-repair-estimate/) give each scope decision a visible CAD cost line. Use the document to understand the structure; verify the actual building, product schedule, labour and supplier inputs 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 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.

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.

Review the Canadian job address

Inspect the existing substrate, access and product selections at the property. Check any local trade or municipal requirements that apply and record unresolved conditions before preparing the final client document.

The patch application line uses 46 sq. ft., approximately 4.27 m². Keep the actual site measurement and the supplier’s selling unit together when you replace this quantity. The example amounts are fictional CAD document inputs, not current rates for Kelowna, British Columbia or another community. A site visit and current supplier information are needed to replace them.

Work through the itemized calculation

Check each extension of quantity and rate in the paired PDF. Two lines from this project are:

- Loose plaster removal: 4 hours × C$76.00 = C$304.00.
- Patch application: 46 sq. ft. × C$25.00 = C$1,150.00.

Adding all 7 rounded line amounts gives C$3,034.00 . The PDF shows 0% tax and the same total before any markup. The sample shows 0% tax only to make the arithmetic visible. Determine any applicable GST, HST or PST and markup for the actual work before sharing a quote.

Plaster wall repair example · CAD Work item | Quantity | Unit rate | Amount |

Protection and defect mapping | 1 job | C$185.00 | C$185.00 |

Loose plaster removal | 4 hours | C$76.00 | C$304.00 |

Backing and bonding allowance | 1 job | C$240.00 | C$240.00 |

Patch application | 46 sq. ft. | C$25.00 | C$1,150.00 |

Finish and feather edges | 10 hours | C$83.00 | C$830.00 |

Return sanding visit | 1 job | C$200.00 | C$200.00 |

Clean-up and paint-ready check | 1 job | C$125.00 | C$125.00 |

Illustrative subtotal | C$3,034.00 |

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.

Keep the product allowance, installation work and any unresolved condition visible as separate decisions. If access or the selected product changes, update the affected quantity or rate and explain the revision before the client relies on the estimate.

Before you send the estimate

- Record crack length, patch area, depth and whether movement is active.
- Separate backing repair, plaster materials and final decoration expectations.
- Resolve the cause of movement or damp before patching and allow required drying stages.
- Loose background or continued movement can change the repair method.

Check the business, client, property, dates, line extensions and notes. The plaster wall repair PDF example (https://quicklyestimates.com/en-ca/samples/plaster-wall-repair-estimate/) shows one way to present them. Its short PDF note lists the brief's scope exclusions; the fuller project limits above should guide your own scope.
