Professional Leak Detection & Plumbing Investigation
At Espy Leak Detection, we specialise in locating hidden water leaks quickly and accurately using advanced, non-invasive techniques. Whether you’re dealing with a suspected underground leak, central heating issue, or unexplained water loss, we provide reliable solutions across Buckinghamshire, High Wycombe, Aylesbury, Marlow and Uxbridge.
Using advanced diagnostic technology including acoustic listening equipment, thermal imaging cameras, tracer gas systems, electronic leak detection (ELD) and pressure testing, we are able to identify the precise source of leaks in:
-
underground water pipes
-
internal plumbing systems
-
central heating pipework
-
underfloor heating systems
-
concealed pipework within floors and walls
-
building fabric and waterproofing failures
Unlike many leak detection companies, our background is in professional plumbing and heating systems. This means we not only locate the leak, but understand the pipework systems behind the problem and can often carry out targeted access and repair works immediately once the source is identified.
Hidden leaks can cause serious structural damage, rising water bills, damp problems and mould growth if left unresolved. Our goal is to pinpoint the problem quickly, minimise unnecessary disruption and provide clear recommendations for repair and drying where required.
We regularly work with homeowners, landlords, managing agents, insurers and loss assessors, providing detailed reports suitable for insurance “Trace and Access” claims.
If you suspect a hidden leak, Espy Leak Detection offers the experience, technology and practical plumbing knowledge needed to resolve the problem properly.
We provide professional leak detection services across:
High Wycombe, Aylesbury, Beaconsfield, Marlow, Uxbridge, Slough, and surrounding areas.
