Leak Detection in Royston
Hidden leaks in Royston found with thermal imaging, acoustic and tracer gas equipment rather than by digging, with full written reports for insurance claims.
Hidden leaks in Royston follow predictable patterns once you know the town’s housing. The Victorian and Edwardian terraces around the High Street, King Street and the historic core have copper and lead pipework that’s now over a century old, often with multiple reconfigurations across the decades. The inter-war and post-war housing north of Icknield Way has heating pipework typically installed in the 1960s and 70s, also now reaching the end of its serviceable life. The chalk geology underlying Royston means very hard water from Affinity Water accelerates pinhole corrosion at copper joints. And the surrounding villages, Therfield, Melbourn, Bassingbourn, Barley, bring substantial period cottages where original plumbing has been working away quietly for far longer than anyone realises.
Specialist non-invasive equipment, full insurance reports, and we work with all major insurers and loss adjusters. Our leak detection service covers thermal imaging through acoustic and tracer gas methods.
Three factors stack against Royston’s housing. First, age, significant portions of the central housing stock are 100+ years old, with original copper and lead pipework now past typical service life. Second, the very hard chalk-aquifer water from Affinity Water accelerates pinhole corrosion at copper joints. Third, the chalk downs geology means groundwater levels can be unpredictable, underground leaks don’t always show as classic dry-area damp signatures, particularly in the older properties on the south-facing slopes.
By the time the water bill spikes or ceiling stains appear, the leak has often been running for weeks. For active leaks where water is visibly escaping, our emergency plumbing service operates 24/7 across SG8.
How we find hidden leaks without damaging period features
Thermal imaging cameras
An infrared camera shows temperature differences across walls, floors and ceilings. A warm patch on a cold floor usually means a hot water pipe leaking underneath; a cold patch in a warm ceiling typically means cold mains escaping above. The camera narrows the search within minutes without touching anything.
Acoustic leak detection
Highly sensitive ground microphones pick up the sound of escaping water travelling through pipework. Particularly useful for underground mains leaks under Royston driveways and gardens, we pinpoint to within 10, 15cm before any digging.
Tracer gas detection
A safe, non-toxic gas (hydrogen-nitrogen mix) introduced into the system at low pressure. It escapes at the leak point and is detected on the surface. Our go-to method for tricky underground heating leaks where thermal imaging alone hasn’t given a clear answer.
Endoscopic cameras
Compact high-resolution cameras inspect cavities and pipework through small access points. Essential for Royston’s listed and period properties where lifting original floors or breaking through plaster needs to be a last resort.

The properties where leaks are hardest to find
Conservation area and listed properties around the High Street
Original pipework runs through buildings that have been altered and reconfigured across multiple eras, joints in places no current drawing shows. Listed building constraints make speculative investigation expensive and slow. Non-invasive detection is essential rather than optional.
Victorian and Edwardian terraces around the older streets
Original copper and lead pipework buried under floors that have been in place for 100+ years. Thermal imaging plus acoustic detection together usually find the source without major access work.
Inter-war and post-war housing with concealed heating pipework
Heating systems retrofitted in the 1960s and 70s often have pipework chased into walls or buried under floorboards. Thermal imaging narrows the area quickly; endoscopic confirmation through a small access point gives certainty before any repair.
Underground mains leaks under driveways and village gardens
Long supply pipes running 15, 25m under block-paved driveways or mature village gardens. Acoustic detection narrows the leak to within centimetres, saving thousands in unnecessary excavation.
Insurance work and reporting
We work routinely with all major UK insurers and loss adjusters. Full written reports with photographs, thermal images and findings provided as standard. Most home policies cover trace-and-access costs as a separate line, typically £5,000 to £10,000 limits.

Frequently asked questions
How quickly can you get to a leak in Royston?
Active leaks where water is visible or the meter is spinning, same-day in most cases. Non-emergency hidden leak detection surveys, usually within 2 to 3 working days.
How long does water leak detection in Royston usually take?
Most domestic leak surveys take 1 to 3 hours on site. Listed and period properties with extensive concealed pipework can take 4 to 6 hours. Underground mains leaks typically 2 to 4 hours. Fixed price quoted before we start.
Will my insurance pay for the leak detection survey?
Most home policies cover trace-and-access costs as a separate line from the repair, typically £5,000 to £10,000 limits. Check your policy wording. We provide invoices and reports formatted for insurance claims.
Will you damage my floors or period features during investigation?
Almost never. Our non-invasive equipment locates the vast majority of leaks without lifting anything. Where access is unavoidable, we plan it carefully, through an under-stairs cupboard, an existing pipe boxing, or a less prominent floor section.
My water bill has tripled but I can't see any leak, what's happening?
Classic underground supply leak symptom. Turn your stopcock off and watch the meter for 30 minutes; if it’s still moving, you’ve got a leak after the meter on your property. Acoustic detection along the supply run typically finds it within an hour.
Do you fix the leak as well as find it?
Yes. We’re a full plumbing and heating company, not just a detection service. Once located, you get a fixed price for the repair before any work starts. 12-month labour guarantee on every repair.
