What is trace and access?

Trace and access is the process of finding the source of a hidden water leak and making it accessible for repair — and it’s a specific section of most buildings insurance policies. If water is coming through your ceiling or a damp patch keeps growing, your insurer will usually ask for a professional investigation before they settle an escape-of-water claim.

That’s what we do. Our leak detection engineers use thermal imaging, acoustic listening, tracer gas and moisture mapping to pinpoint the leak to within centimetres — before anything is opened up. We then document everything in a report written for insurance claims.

Does insurance cover trace and access?

Trace and access may be covered under buildings insurance, depending on the policy. We provide insurance-ready reports and evidence to support the claim. Where your policy includes trace and access cover, it typically pays towards locating the leak and the access work needed to reach it — we’ll help you understand your cover position before any work starts.

• The repair of the leaking pipe itself is often not covered (that’s usually maintenance) — but the damage the water caused, and finding the leak, usually is.
• Insurers can reject or reduce claims when the leak’s source was never professionally confirmed. A proper report protects you.
• Cover limits vary. Bring us your policy wording — we’ll tell you honestly what’s likely covered before any work starts.

How our investigation team finds your leak — without the damage

• Thermal imaging — temperature traces of hot-water and heating leaks behind walls and under floors.
• Acoustic listening — the sound signature of pressurised leaks, even under concrete.
• Tracer gas — the smallest, deepest leaks: safe gas in the pipe surfaces exactly at the fault.
• Moisture mapping — calibrated readings that map how far water has travelled.
• Pressure testing — confirms which system is losing water: heating, hot or cold supply.

What’s in your trace & access report

Delivered in 24–48 hours, written to be read by loss adjusters: cause and exact location of the leak; method and instrument evidence; access works carried out and why they were necessary; moisture damage extent; repair recommendation. Written for insurers, housing authorities and managing agents.

Step by step

1. Call or WhatsApp a photo — we’ll tell you straight away if it sounds like a trace & access claim.
2. Same-day/next-day survey — one of our engineers attends; non-invasive investigation, source confirmed.
3. Report in 24–48h — insurance-ready evidence pack.
4. Access + repair — our repair team fixes what the investigation found (no second contractor).
5. Claim support — we can speak with your insurer or adjuster directly.

Trace & access vs leak detection — what’s the difference?

Leak detection is the finding. Trace and access is the finding plus the insurance-framed process — locating, accessing, and documenting so the claim pays. If you’re claiming, you want trace & access. If you just want the leak found and fixed with no claim, see our leak detection service.

Frequently asked questions

Will my insurer pay for trace and access?
Trace and access may be covered under buildings insurance, depending on the policy. We confirm your cover position before any work starts and provide the report and evidence to support your claim.

Is the leak repair itself covered?
Often not — pipe repair is usually classed as maintenance. The finding, access and water damage usually are. We quote the repair separately and honestly.

How fast can you attend?
Same-day emergency attendance across London & Surrey in most cases.

Do you deal with the insurer for me?
Yes — our reporting team can liaise with your insurer or loss adjuster and supply the evidence they ask for.

What if you can’t find the leak?
We find it. Our methods cover heating, hot/cold supply, waste and ingress — and we don’t leave until the source is confirmed and documented.

Do you do the repairs too?
Yes — detection, access, repair and reinstatement. One company from investigation to report to repair — one bill.
