Recognize what has actually changed

A change can arise from a concealed condition, a customer preference or an omission in the original proposal. Those are different situations and should be described accurately. Ask what new fact or request makes the change necessary. A discovered damaged support is not the same as deciding to install a different finish. Record who proposed the change and when. Keep the original estimate intact rather than allowing its wording to be quietly rewritten. The purpose is to make the development of the job visible, not to assume that every change is improper.

Capture the condition before it disappears

If opening the work reveals something unexpected, ask for photographs that show both the location and the detail. Include a scale where useful and a written description from the person who inspected it. Identify what has been removed already and what remains. Photographs of loose debris without context may not explain which part of the house it came from. You do not need to approach an unsafe opening to verify it personally. Ask for a record that can be reviewed from a safe place and retained after the area has been covered.

Define the revised scope

The change document should state the added or removed tasks and their relationship to the original repair. Ask whether the proposal solves the newly identified condition or merely allows work to proceed. Identify preparation, access and finish restoration affected by the change. If the repair boundary grows from one section to a larger area, record the new quantity and reason. Keep optional improvements separate. A useful description lets you understand what would happen if you approve only the necessary change and decline an unrelated upgrade offered at the same time.

Show the price and schedule effect

Ask for the additional or reduced amount, applicable taxes and revised total. If the amount cannot yet be established, agree on the next investigation and its limit rather than authorizing an undefined expansion. Record whether material delivery, curing or another trade changes the completion sequence. Ask if previously approved work is being removed or credited. A change should not be represented only by a new final invoice. Ontario's repair guidance discusses written changes when new work or pricing is agreed; consult its current explanation for the consumer-contract context of your job.

Keep approval specific

Use an explicit written response that refers to the change version and the accepted scope. Avoid a casual 'go ahead' in a message thread containing several options. If someone else in the household is coordinating the visit, decide who can authorize changes before work starts. Confirm whether discussion at the work area is only a request for information or an instruction to proceed. This is particularly useful when a provider speaks to different occupants on different days. A short clear approval record can prevent a later disagreement about what a conversation meant.

Distinguish protection from final reconstruction

An exposed area may need temporary protection while you decide. Ask the provider to separate that immediate protective task from permanent additional work, explaining what can safely wait and what cannot. Do not let a sales deadline stand in for evidence of urgency. Equally, do not delay a genuine safety response simply to complete paperwork. Once the immediate situation is controlled, record what was done, why and what remains open. You can then review the lasting repair using the same scope, evidence and approval discipline as the original job.

Carry the change into completion records

At handover, reconcile each accepted change with the finished work and invoice. Mark declined options as declined so they do not reappear ambiguously in the final total. Save the photos, revised drawings or measurements that explain the altered work. If the completed method differs again from the approved change, request an explanation before treating the record as complete. The final file should allow a future provider to understand both the starting condition and the repair that actually took place, without assuming the first quotation describes the finished assembly.

Keep a numbered change list for a job with several revisions. Each entry should lead to its finding, approval and cost effect, so the final account can be followed without reconstructing message threads.

Questions for the provider

  1. What new evidence makes this change necessary?
  2. What is the revised total and completion sequence?
  3. What temporary protection is needed if I pause the permanent work?
