Our Leak Detection Services in Truro

Leak detection in Truro using thermal imaging camera

We offer comprehensive leak detection services to locate leaks anywhere in your Truro property. Behind walls, beneath floors, underground in gardens or driveways, or within your heating system. Our approach combines multiple detection methods so 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 specialist water leak detection techniques that pinpoint the exact leak location without unnecessary damage.

Central Heating Leak Detection

We find leaks in radiator pipework, boiler connections and sealed heating systems with our central heating leak detection service. Particularly useful 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 excavation.

Underground Leak Detection

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

Commercial Leak Detection

Full commercial leak detection services for offices, retail units, restaurants, hotels and mixed-use buildings throughout Truro.

Trace and Access

Insurance-approved trace and access investigations 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 engineers use multiple specialist technologies and choose the most appropriate methods based on your property type, where we suspect the leak might be, and what kind of pipework is involved. This multi-method approach gives us the best chance of pinpointing the leak while keeping disruption to a minimum.

Thermal Imaging Leak Detection

Our thermal imaging leak surveys use infrared cameras to detect temperature differences caused by water escaping from pipes. This works particularly well for locating leaks behind walls, within ceiling voids and beneath floors without any need for exploratory damage. In Truro's older Georgian and Victorian properties, thermal imaging is especially valuable for tracing leaks through solid walls and beneath suspended timber floors, helping us identify the actual source rather than just where the water ends up.

Acoustic Listening Equipment

Acoustic listening leak detection uses sensitive microphones to detect the sound of water escaping under pressure. This technology works well for tracing leaks in mains supply pipes, both inside your property and underground. In Truro, we often use acoustic equipment to trace leaks in supply pipes running beneath front gardens and driveways, particularly in properties with longer runs from the pavement to the house. Our equipment filters out background city noise so we can identify exactly where the leak is loudest.

Tracer Gas Detection

For central heating systems and underfloor heating circuits, tracer gas leak detection is often the most effective method. We introduce a safe, inert gas (typically a hydrogen-nitrogen mix) into the system. The gas escapes at the leak point and rises through flooring and wall materials, where our detectors locate it at the surface. Many Truro properties have had extensions or renovations that include underfloor heating, and tracer gas allows us to pinpoint leaks in these circuits without lifting large areas of flooring unnecessarily.

Other Detection Methods

Depending on your situation, we may also use moisture mapping to track dampness through building materials, endoscopic cameras to inspect pipe interiors and cavities, or pressure testing to confirm whether a system is leaking. For water mains leak detection and slab leak detection beneath concrete floors, we combine multiple methods to get it right.

Leak Detection for Truro Property Types

Truro's property mix presents specific challenges for leak detection. The city includes everything from Georgian townhouses in the centre to Victorian and Edwardian terraces, inter-war semis, post-war council housing and modern family homes. Each construction type has different pipe materials, layouts and common leak points. Our engineers have worked across all of them.

Georgian and Victorian Properties

The older properties around Truro city centre and Lemon Street area often feature original lead or iron pipework, solid walls, and suspended timber floors. Leaks in these homes can be particularly challenging because water travels along joists and through voids before becoming visible. We use thermal imaging and moisture mapping to trace leaks accurately, identifying the actual source rather than just where dampness appears on ceilings or walls below.

Semi-Detached and Terraced Houses

Truro has many inter-war and post-war semi-detached homes, often with copper pipework and solid ground floors at the rear with suspended timber at the front. Common issues include leaks from bathroom and kitchen plumbing systems and pipework, central heating pipework running beneath ground floors, and supply pipes entering the property. Our acoustic and thermal equipment can trace pipes hidden within wall cavities and floor voids without opening up the structure.

Modern Developments

Newer properties towards Threemilestone, Treliske and around the outskirts of Truro often have plastic pipework that's less prone to corrosion, but leaks still occur at joints, manifolds and connections. Many have also been built with underfloor heating, which requires specialist detection when a leak develops in the circuit. We can trace these systems accurately without unnecessary disruption to your flooring.

Commercial and Mixed-Use Properties

Truro's position as Cornwall's administrative and commercial centre means it has numerous commercial properties, including shops, restaurants, offices, the Royal Cornwall Hospital, and care facilities. We provide professional leak detection for commercial premises with flexible scheduling to minimise business disruption. Our detailed reports are formatted for building managers, landlords and insurers as required.

Signs You Might Have a Leak

Many leaks stay hidden for weeks or months before becoming obvious. By the time you see visible damage, a lot of water may already have been lost and the structure affected. Here are warning signs that suggest you should get a professional leak detection survey:

  • Water bill has gone up but your usage hasn't changed
  • Boiler pressure keeps dropping and needs topping up
  • Damp patches, staining or bubbling paint on walls or ceilings
  • Musty or mouldy smell, especially where there's no obvious moisture source
  • Sound of running water when everything is switched off
  • Warm or wet spots on floors (particularly with underfloor heating)
  • Water pressure has dropped throughout the property
  • Water meter spinning when nothing is running

If you've noticed any of these in your Truro property, it's worth investigating sooner rather than later. Catching a leak early typically means simpler repairs, lower costs and less damage overall.

Truro's Water and Your Pipes

Truro's water supply can be harder on pipes than in some other areas of the UK. The mineral content can accelerate wear on certain pipe materials over time, particularly in older properties with original copper or iron pipework. If your boiler keeps losing pressure or you've noticed pinhole leaks developing in your heating system, professional detection can help identify whether you have an isolated leak or a more widespread issue that needs addressing.

How Our Leak Detection Process Works

Tracer gas leak detection being performed in Truro property

When you contact us about a suspected leak in Truro, 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 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 between two and six hours, depending on the property and how complex the leak is.

Findings and Report

Once we've located the leak, we explain what we've found, show you the evidence (thermal images, moisture readings, etc.) and mark the leak location. You'll receive a written report with photographs, suitable for your insurer or contractor.

Leak Repair

Once we've found the leak, we often carry out minor repairs the same day. For more complex jobs, we can provide you with a detailed quote or you can choose your own preferred contractor to complete the repair.

Insurance Claims and Trace & 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 repairing the damage itself.

We provide insurance-standard reports that include:

  • Description of the investigation methods used
  • Photographic and thermal imaging evidence
  • Precise leak location with reference to property layout
  • Technical findings and pipe identification
  • Recommendations for repair

These reports are formatted to support your claim and give your insurer the information they need to process it. We can liaise directly with loss adjusters when required and provide additional documentation if requested. You can learn more about what trace and access covers on our dedicated guide.

Not sure whether your policy includes trace and access cover? Check the policy documents or contact your insurer before arranging your visit. We're happy to discuss the likely investigation scope so you can confirm cover in advance.

Hidden leaks rarely fix themselves. What starts as a minor drip behind a wall or beneath a floor can escalate into significant structural damage, affecting timber joists, plasterwork and even electrical systems. The longer a leak goes undetected, the more water is wasted and the greater the repair bill becomes.

Professional leak detection takes the guesswork out of finding the source. Rather than tearing up floors or cutting into walls hoping to find the problem, our targeted approach means repairs can be planned precisely. This reduces disruption, keeps costs down and gets your property back to normal faster.

For Truro homeowners dealing with insurance claims, having a professional trace and access report can make the difference between a smooth claim process and a frustrating back-and-forth with your insurer. Our documentation provides the evidence needed to support your case.

Frequently Asked Questions

What are the signs of a hidden water leak in my Truro property?

Common signs of water leaks in Truro properties include unexplained increases in water bills, boiler pressure dropping regularly (needing topping up more than once a month), damp patches on walls or ceilings that won’t dry, musty smells particularly in basements, mould growth in unusual places, the sound of running water when all taps are off, and warm or cold spots on floors with underfloor heating. In Truro’s river valley location, natural dampness can mask leak symptoms, so any persistent moisture beyond normal condensation should be investigated.

You are responsible for all pipework within your property boundary, from where the water supply pipe enters your land to all internal plumbing. South West Water is responsible for the water main in the street and the communication pipe up to your property boundary (usually where your outside stop tap is located). If you have a leak on your side, you’ll need professional leak detection. If it’s outside your boundary in Truro, report it to South West Water on 0344 346 1010.

Non-invasive leak detection uses three main technologies to find leaks without excavation or damage. Acoustic listening devices detect the sound of escaping water through pipes, distinguishing it from background noise like Truro’s traffic. Thermal imaging cameras identify temperature differences where water is escaping, particularly effective for underfloor heating leaks. Tracer gas (a safe hydrogen/nitrogen mix) is introduced into empty pipes – the gas escapes through the leak and is detected by sensitive equipment above ground, even through concrete or Truro’s clay soil. These methods pinpoint leaks to within one square metre accuracy.

Most home insurance policies include ‘Trace and Access’ cover, which pays for finding and accessing hidden water leaks. This typically covers the cost of leak detection services and making good any damage caused by accessing the leak. However, insurers usually require a written quotation before approving leak detection work. The actual pipe repair is often covered under separate ‘escape of water’ provisions. We provide comprehensive, insurance-approved reports with photos and exact leak locations that Truro property insurers accept.

Boiler pressure loss is commonly caused by hidden leaks in your central heating system, particularly in pipework under floors or within walls. In Truro’s Georgian and Victorian properties, aging copper pipes corrode faster due to our river valley moisture levels. Other causes include faulty pressure relief valves or expansion vessels. If you’re topping up pressure more than once a month, or losing more than 0.5 bar weekly, you likely have a leak. Professional leak detection can locate the exact failure point without damaging period features or floors.

Truro’s position where the Kenwyn, Allen and Truro rivers converge creates high water tables that fluctuate with rainfall and tides. This affects leak detection in several ways: natural groundwater can mask leak symptoms, making visual detection harder; tidal pressure stresses underground pipes, especially within 200 metres of the rivers; and acoustic detection must filter out water movement sounds. Our equipment is specifically calibrated for these river valley conditions, distinguishing between groundwater infiltration and active leaks.

Most residential leak detection in Truro takes 2-6 hours depending on property size and complexity. Georgian terraces with multiple floor levels typically take 3-4 hours, while modern single-storey properties average 2-3 hours. Listed buildings in Truro’s conservation areas may take longer due to careful non-invasive requirements. Commercial properties like shops on Lemon Quay or offices near County Hall can take 4-8 hours. We book the full day to ensure thorough detection without rushing.

While plumbers can perform basic leak repairs, leak detection specialists use advanced technology and techniques specifically designed to find hidden leaks without damage. We use thermal imaging cameras, acoustic correlators, and tracer gas equipment that most plumbers don’t have. Our expertise includes understanding how Truro’s geology, Victorian infrastructure, and river valley conditions affect water systems. Specialists provide insurance-approved reports with photographic evidence and exact coordinates. Think of it as the difference between a GP and a specialist consultant – both valuable, but specialists handle complex cases requiring specific expertise and equipment.
