Leak detection in London
A trace and access survey is needed when there is evidence of a hidden leak that cannot be located by conventional methods: unexplained damp patches, mould or peeling paint, a sudden rise in water bills, persistent low water pressure, the sound of running water when nothing is on, or unexplained puddles.
"Trace and access" is a standard cover in most home insurance policies. It usually covers the cost of finding the source of a leak, making the area accessible so it can be repaired, and repairing damage caused by the search. It does not cover repairing the leak itself. Check your policy to confirm your cover.
To claim: contact your insurer before any work and tell them about the leak. Send them our insurance-approved quote. Once approved, we attend, carry out the survey and provide a comprehensive report pinpointing the leak. You pass the report to your insurer, who reimburses your costs. We can then quote for the repair and for making good.
