Ask about the work before it starts
Contact your insurer and describe the symptoms. Ask whether investigation or opening up needs approval and what evidence they need. Note any claim reference and give relevant reporting requirements to the company carrying out the work.
Separate the parts of the job
Finding the source, opening a wall or floor, repairing the pipe and restoring finishes are separate activities. A policy can treat them differently. The Track N Fix residential package includes detection, access and plumbing repair; decorative and remedial reinstatement is excluded.
Keep the evidence together
Keep the investigation report, photographs, booking information and invoices together. A Trace & Access report records the work and findings; it does not promise reimbursement or decide what a policy covers. Your insurer applies the policy, excess and limits to the claim.
