Our Leak Detection Services

We offer a comprehensive range of leak detection services to locate leaks anywhere in your Harpenden 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 expert water leak investigation services that pinpoint the exact leak location.

Central Heating Leak Detection

We find leaks in radiator pipework, boiler connections and sealed heating systems with our professional heating system leak detection. 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 specialist underfloor heating investigations that avoid unnecessary damage.

Underground Leak Detection

We locate leaks in buried supply pipes, service pipes and drainage systems across gardens and driveways with advanced underground pipe tracing.

Commercial Leak Detection

Full business and commercial property leak services for offices, retail, hospitality, healthcare and industrial properties across Harpenden.

Trace and Access

Insurance-approved trace and access surveys for insurance claims with detailed 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 detection equipment uses ground microphones to detect the sound of water escaping under pressure. Excellent for tracing leaks in mains supply pipes.

Tracer Gas Detection

For heating systems and underfloor circuits, hydrogen and helium tracer gas methods introduce 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 Harpenden Property Types

Harpenden's property mix presents unique challenges for leak detection. The town includes everything from charming Victorian and Edwardian homes near the High Street to spacious detached houses in areas like Southdown and modern developments. Each construction type has different pipe materials, layouts and common leak points.

Period and Victorian Properties

The older properties around Harpenden town centre and surrounding conservation areas often have a mix of original and updated plumbing. Lead and copper pipework from different eras can create weak points at joints. Our thermal imaging and moisture mapping can trace these complex pipe runs without opening up the structure.

Large Detached and Family Homes

Harpenden is known for its larger family homes, many with extensive gardens and long supply pipe runs from the road. These properties often have more complex plumbing systems, including multiple bathrooms and extended pipework. Underground leaks between the meter and the house are common and require specialist detection.

Commercial and Mixed-Use Properties

Harpenden's thriving High Street and business areas include retail units, restaurants, offices and healthcare premises. We provide comprehensive plumbing and pipework leak investigations 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 Harpenden?

In most cases we can arrange a leak detection visit in Harpenden within 24–48 hours, and often sooner for urgent issues. For many customers in Harpenden AL5 and nearby areas such as St Albans, Wheathampstead and Redbourn, 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 Harpenden 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.
