OUR
PROCESS

From your first call to a fully documented result — here’s exactly how we work. No guesswork, no unnecessary damage, no surprises on the bill.

01
Site Visit
We attend your property anywhere in London, North London, Barnet, and surrounding areas to assess the issue, identify visible signs of water damage, and carry out an initial leak investigation.
02
Specialist Leak Detection (Non-Invasive)
We use advanced non-invasive leak detection methods including thermal imaging, tracer gas, acoustic detection, and moisture mapping — pinpointing hidden leaks under floors, behind walls, and within ceilings without unnecessary disruption.
03
Trace & Access London (Insurance Approved)
Once located, we carry out trace & access works to expose the leak using controlled, targeted methods. Our approach is fully aligned with insurance trace & access policies, helping you recover costs where applicable.
04
Leak Repair & Plumbing Works
We carry out professional leak repairs, replacing faulty pipework, fittings, or components to restore your plumbing or heating system efficiently.
05
Leak Detection Report for Insurance
We provide a detailed leak detection report including photographic evidence, thermal & moisture readings, confirmation of leak source, and works carried out — suitable for insurance claims, loss adjusters, and trace & access submissions.
06
Making Good & Reinstatement Works
We offer making good services, restoring affected areas following leak repairs, with full reinstatement options available — leaving your property as we found it.
07
Aftercare & Insurance Support
Our service doesn’t stop once the leak is fixed. We provide ongoing aftercare support, assistance with insurance claims, access to an independent loss adjuster, and clear documentation to help maximise your chances of a successful claim — from start to finish, and beyond.

WE WORK
WITH YOUR
INSURER

Our Guarantee

TRACE
& ACCESS

Trace & Access is the specific term used by insurers for the process of finding a hidden leak, opening the minimum area to expose it, and documenting everything for your claim. We are specialists in this service.

✓ Covered by Most Home Insurance Policies
Most buildings and contents insurance policies include Trace & Access cover. This means your insurer pays for the cost of finding and accessing the leak — check your policy schedule for details.
