Ask what happens after detection
Does the instruction include necessary access, plumbing repair, parts, testing and a written report? Establish the boundaries before comparing totals.
Check exclusions
Finishing work, commercial systems and additional unrelated faults may be separate. Ask how changes to the instruction will be agreed.
Clarify claims and limits
Ask how uncertainty, access restrictions and inconclusive tests will be explained. No method can promise a result in every condition.
