Our Leak Detection Services in Hertfordshire

We offer a comprehensive range of leak detection services to locate leaks anywhere in your Hertfordshire property — behind walls, beneath floors, underground, within your heating system. Our multi-method approach means we find the actual source of the problem, not just where the water ends up. As a leak detection specialist, we focus exclusively on finding and diagnosing leaks across the county.

Water Leak Detection

We locate hidden leaks in mains supply pipes, internal plumbing and waste systems using advanced water leak detection techniques that pinpoint the exact leak location with precision.

Central Heating Leak Detection

We find leaks in radiator pipework, boiler connections and sealed heating systems with our specialist central heating leak detection service. Ideal when your boiler keeps losing pressure.

Underfloor Heating Leak Detection

We trace leaks in underfloor heating circuits beneath screed, tile and laminate floors using non-invasive underfloor heating leak detection methods that avoid unnecessary floor lifting.

Underground Leak Detection

We locate leaks in buried supply pipes, service pipes and drainage systems across gardens and driveways with expert underground leak detection that minimises excavation.

Commercial Leak Detection

Full commercial leak detection services for offices, retail, hospitality, healthcare and industrial properties across Hertfordshire with flexible scheduling.

Trace and Access

Insurance-approved trace and access survey services with detailed reports, photographic evidence and technical findings to support your insurance claim.

Leak Detection Technology We Use

Finding a hidden leak takes more than guesswork. Our leak detection engineers use multiple non-destructive testing technologies, choosing the most appropriate methods based on your property type and the suspected leak location. This multi-method approach gives us the best chance of pinpointing the leak while keeping disruption to a minimum.

Thermal Imaging Cameras

Our thermal imaging leak detection surveys use infrared cameras to detect temperature differences caused by escaping water. Ideal for locating leaks behind walls and beneath floors without causing damage.

Acoustic Listening Equipment

Acoustic listening detection uses highly sensitive microphones to detect the sound of water escaping under pressure. Excellent for tracing leaks in mains supply pipes and pressurised systems.

Tracer Gas Detection

For heating systems and underfloor circuits, tracer gas leak detection introduces a safe, inert gas that escapes at the leak point and rises to the surface for precise detection.

Moisture Mapping

We use advanced moisture meters and mapping to track dampness through building materials, helping trace the leak path back to its source with precision — essential for identifying the true origin point.

Leak Detection for Hertfordshire Property Types

Hertfordshire's housing stock varies considerably — from Victorian and Edwardian properties in historic market towns to modern developments in new towns and commuter areas. Each property type has different construction methods, pipe materials and common leak points that our engineers are trained to handle.

Period and Victorian Properties

Older properties throughout St Albans, Hertford and historic market towns often have a mix of original and updated plumbing. Leaks commonly occur at joints between different pipe materials. Our thermal imaging and moisture mapping can trace these complex pipe runs without opening up the structure.

New Towns and Modern Developments

Properties in Welwyn Garden City, Stevenage, Hemel Hempstead and newer developments often have plastic pipework that's less prone to corrosion, but leaks still occur at joints and manifolds. Many newer properties also have underfloor heating, which requires specialist detection when a leak develops.

Commercial and Industrial Buildings

Hertfordshire is home to numerous commercial premises, from offices in the M1 corridor to distribution warehouses and retail parks. We provide professional plumbing leak detection for commercial premises with flexible scheduling to minimise business disruption.

Signs You Might Have a Leak

Many leaks stay hidden for weeks or months before becoming obvious. By the time you see visible damage, significant water may already have been lost. If you've noticed any of these warning signs, our leak detection services can help — you can also use our quick leak checker tool to assess your situation.

Water bill has increased unexpectedly

Boiler pressure keeps dropping

Damp patches on walls or ceilings

Musty or mouldy smell

Sound of running water when taps off

Warm or wet spots on floors

Water meter running when water off

Low water pressure throughout

Catching a leak early typically means simpler repairs, lower costs and less disruption to your home or business. If you've received a notification from your water supplier about suspected high usage, professional leak detection can help identify the source quickly.

How Our Leak Detection Process Works

When you contact us about a suspected leak in Hertfordshire, here's what happens:

Initial Conversation

We discuss your situation over the phone. What have you noticed, where, and when? This helps us understand what kind of leak we're likely dealing with and which equipment to bring to your Hertfordshire property.

Site Survey

Our engineer inspects your property, looks at the visible damage, checks systems (boiler pressure, water meter, etc.) and identifies access points. We explain our approach before starting any detection work.

Detection Work

Using thermal imaging, acoustic listening, tracer gas, moisture mapping or a combination, we systematically trace the pipe runs and isolate the leak source. This usually takes 1–3 hours depending on complexity.

Findings and Report

Once we've located the leak, we explain what we've found, show you the evidence and mark the leak location. You'll receive a written report with photographs, suitable for insurers and contractors.

Repair Guidance

We advise on repair options and can carry out minor plumbing repairs where appropriate. For larger jobs, we provide clear information for your contractor or can quote for the work.

Think You Have a Leak?

Don't let water damage get worse. Our engineers can locate your leak quickly using non-invasive technology.

Insurance Claims & Trace and Access

If you're claiming on your home insurance for water damage, your policy may include trace and access cover. This typically pays for the investigation to find where the leak is coming from, separate from the cost of repairs.

Not sure whether your policy includes cover? Check your policy documents or contact your insurer before arranging your visit. We work with all major insurers and loss adjusters across Hertfordshire.
