Leak Detection in Baldock
Finding hidden leaks across SG7 - without damaging period features
Leak detection in Baldock has a particular twist: the town centre is genuinely old, with housing stretching back to Georgian and earlier periods, and the original copper and lead pipework in some of these properties has been quietly degrading for well over a century. The Grade II listed townhouses on High Street and Hitchin Street, the Georgian and Victorian terraces around the conservation area, and even the inter-war semis on the older streets all share one common feature – pipework that’s older than most of the homeowners. Add the very hard chalk-aquifer water that comes from the same springs that feed the River Ivel rising in the town, and you’ve got an environment where pinhole corrosion and joint failures are constant features of plumbing life.
Specialist non-invasive equipment, full insurance reports, and we work with all major insurers and loss adjusters. Our leak detection service covers everything from thermal imaging through to acoustic and tracer gas methods.
Why hidden leaks are common in Baldock homes
Three factors stack against Baldock’s housing. First, age – significant portions of the central housing stock are 150+ years old, with original copper and lead pipework now well past the typical service life. Second, the very hard chalk-aquifer water from Affinity Water accelerates pinhole corrosion at copper joints throughout the town. Third, the proximity of the Ivel Springs and the underlying chalk geology means groundwater levels here are higher than in towns set on heavier clay – and underground leaks don’t always show as classic dry-area damp signatures.
By the time the water bill spikes or ceiling stains appear, the leak has often been running for weeks. Speed of hidden leak detection matters – both for the water saved and the structural damage prevented. For active leaks where water is visibly escaping, our emergency plumbing service operates 24/7 across SG7.

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 running under Baldock 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 Baldock's listed and period properties where lifting original timber floors or breaking through plaster cornices needs to be a last resort.
The properties where leaks are hardest to find
Grade II listed townhouses on High Street and Hitchin Street
Original pipework runs through buildings that have been altered, extended and reconfigured across multiple centuries - joints in places no drawing shows. Listed building constraints make speculative investigation work expensive and slow. Non-invasive detection is essential rather than optional.
Georgian and Victorian terraces around the conservation area
Original copper and lead pipework buried under floors that have been in place for 100–200 years. Thermal imaging plus acoustic detection together usually find the source without major access work.
Inter-war semis 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 repair.
Underground mains leaks under driveways
Long supply pipes running under block-paved or gravel driveways, often 15–25m on the older detached properties on the town outskirts. Acoustic detection narrows the leak to within centimetres, saving thousands in unnecessary excavation.

Areas we cover for leak detection around Baldock
FAQs
How quickly can you get to a leak in Baldock?
Active leaks where water is visible or the meter is spinning – same-day in most cases. Non-emergency hidden leak detection surveys, usually within 2–3 working days.
How long does leak detection in Baldock usually take?
Most domestic leak surveys take 1–3 hours on site. Listed and period properties with extensive concealed pipework can take 4–6 hours because of the additional care needed. Underground mains leaks typically 2–4 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–£10,000 limits. Check your policy wording. We provide invoices and reports formatted for insurance claims and can liaise with your insurer directly.
Will you damage my original floorboards or period features?
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. For listed properties we minimise access work as a matter of routine.
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.
