Our Leak Detection Services

We offer a comprehensive range of leak detection services to locate leaks anywhere in your Hatfield 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.

Water Leak Detection

We locate hidden leaks in mains supply pipes, internal plumbing and waste systems using dedicated water leak detection specialists who pinpoint the exact leak location.

Central Heating Leak Detection

We find leaks in radiator pipework, boiler connections and sealed heating systems with our expert 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 precision underfloor heating leak detection methods.

Underground Leak Detection

We locate leaks in buried supply pipes, service pipes and drainage systems across gardens and driveways with underground pipe and water leak detection.

Commercial Leak Detection

Full tailored commercial leak detection for offices, retail, hospitality, healthcare and industrial properties across Hatfield.

Trace and Access

Insurance-approved complete trace and access guide services with detailed leak investigation reports, photographic evidence and findings to support your 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

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

Acoustic Listening

Sensitive acoustic listening devices detect the sound of water escaping under pressure. Excellent for tracing leaks in mains supply pipes and buried pipework.

Tracer Gas Detection

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

Leak Detection for Hatfield Property Types

Hatfield's property mix presents unique challenges for leak detection. The town includes everything from post-war housing estates and 1960s terraces to the large-scale new build developments around Ellenbrook and Hatfield Garden Village. Each construction type has different pipe materials, layouts and common leak points.

New Build Developments

Hatfield has seen significant residential growth in recent years, with major developments at Ellenbrook, Hatfield Garden Village and around the former aerodrome site. While newer plastic pipework is less prone to corrosion, leaks still occur at joints, manifolds and connections. Many newer properties also have underfloor heating, which requires specialist detection when a leak develops in the circuit.

Post-War and Mid-Century Properties

Much of Hatfield's established housing dates from the post-war New Town expansion, with estates across Birchwood, Oxlease, South Hatfield and The Ryde. These properties often have a mix of original copper and updated plastic plumbing, and 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.

Commercial and Educational Properties

Hatfield is home to the University of Hertfordshire, Hatfield Business Park and numerous commercial premises along the A1(M) corridor. We provide reliable plumbing leak detection and repair 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 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.

How Our Leak Detection Process Works

When you contact us about a suspected leak, 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.

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.

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 1–4 hours for domestic properties and 2–6 hours for commercial premises.

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.

Repair Guidance

We advise on repair options and can carry out minor repairs same day. For larger jobs, we provide clear information and a quote, or you can choose your preferred contractor.

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 trace and access survey 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.

Frequently Asked Questions

How quickly can you attend a leak in Hatfield?

In most cases we can arrange a leak detection visit in Hatfield within 24–48 hours, and often sooner for urgent issues. For many customers in Hatfield AL10 and nearby areas such as Welwyn Garden City, Welham Green and Brookmans Park, we're able to offer same-day or next-day appointments depending on our schedule.

What types of leaks can you find?

We specialise in locating hidden leaks that are difficult to trace without specialist equipment. This includes mains water supply pipe leaks, internal plumbing and waste pipes, central heating and radiator circuits, underfloor heating systems and underground leaks in gardens, driveways and yards.

Will you need to rip up my floors or damage walls to find the leak?

Our aim is always to minimise disruption. In most cases we can locate the leak using non-invasive methods such as thermal imaging cameras, acoustic microphones, tracer gas and moisture meters. This allows us to trace pipe routes and identify the leak location without lifting floors or breaking into walls unnecessarily.

Can you help with home insurance and trace and access cover?

Yes. Many Hatfield customers contact us because their home insurance includes trace and access cover. We provide detailed written reports with photographs, equipment used and clear findings, which are designed to support insurance claims.

Do you repair the leak as well as finding it?

Our primary focus is professional leak detection, but in many cases we can carry out minor repairs at the same visit, such as fixing accessible pipe joints or small sections of pipework. Where more extensive work is required, we'll clearly explain the options, provide a quote where appropriate, or supply the information your chosen plumber or builder needs.
