Devon Leak Detection Services

From residential plumbing problems to complex commercial systems, our specialist engineers handle every type of water leak investigation across the county.

Central Heating Leak Tracing

If your boiler pressure keeps dropping or you're constantly topping up the system, there's likely a leak somewhere in your heating circuit. We find it without ripping up floors unnecessarily.

  • Pressure loss investigations
  • Radiator and pipework leaks
  • Sealed system diagnostics

Concrete Slab & Foundation Leaks

Leaks beneath solid floors are notoriously difficult to find. Our acoustic and thermal equipment lets us pinpoint the exact location before any concrete is broken out.

  • Leaks under floor slabs
  • Foundation pipe failures
  • Targeted access with minimal excavation

Insurance Trace & Access

Need documentation for an insurance claim? We provide comprehensive reports including moisture readings, thermal images, and photographic evidence—all formatted for insurers.

  • Detailed written reports
  • Photographic and thermal evidence
  • Moisture mapping data

Mains Supply Pipe Leaks

A leak on your incoming water main can cause high bills, low pressure, or even a warning from your water company. We trace these leaks from the boundary stopcock to your property.

  • High water bill investigations
  • Meter running when taps off
  • Water company leak notices

Underfloor Heating Investigations

Wet underfloor heating systems can develop leaks that are invisible from above. We test and trace faults in heating loops without lifting your entire floor.

  • Cold patches on heated floors
  • Pressure drop in UFH manifold
  • Individual loop isolation testing

Hidden Water Leak Detection

Not sure where the damp is coming from? We investigate mysterious moisture problems in walls, floors, and ceilings to identify the true source—whether it's a leak, condensation, or penetrating damp.

  • Unexplained damp patches
  • Bathroom and kitchen leaks
  • Moisture behind tiles and units

Commercial & Business Premises

Leaks in commercial buildings mean lost productivity and potential liability. We work around your operations—including evenings and weekends—to minimise business disruption.

  • Offices, shops, and retail units
  • Schools, care homes, and public buildings
  • Out-of-hours service available

External & Underground Pipes

Pipes running beneath driveways, gardens, and pathways can leak for months undetected. We locate these buried leaks precisely so repairs are targeted and cost-effective.

  • Garden and driveway pipe runs
  • Leaks under patios and paths
  • Buried supply pipe tracing

Internal Plumbing Leaks

Dripping taps and running toilets waste thousands of litres. But concealed pipework—hot and cold feeds, manifolds, and waste pipes—can also fail. We trace and diagnose all internal plumbing faults.

  • Hot and cold supply pipes
  • Concealed waste pipework
  • Toilet cisterns and overflows

How Devon Leak Detection Finds Leaks Without Causing Damage

Our engineers use a combination of specialist equipment and proven techniques to trace leaks with pinpoint accuracy—saving property owners in Exeter, Plymouth, Torquay, and across Devon from unnecessary excavation and repair costs.

Advanced Detection Equipment

Modern leak detection has moved far beyond simply listening for drips. We deploy a range of professional-grade tools, each suited to different scenarios, so we can adapt our approach to your property and the type of leak suspected.

By combining multiple methods, our team achieves a high first-visit success rate and can often locate a leak within hours rather than days—whether you're in Newton Abbot, Barnstaple, Tiverton, or anywhere else in Devon.

  • Thermal Imaging Cameras – Detect temperature variations in walls, floors, and ceilings that indicate hidden moisture or leaking pipes.
  • Acoustic Listening Equipment – Ground microphones and electronic amplifiers pick up the sound of water escaping from pressurised pipes, even through concrete.
  • Tracer Gas Detection – A safe hydrogen-nitrogen gas mix is introduced to pipes; our sensors detect where it escapes, revealing the leak point.
  • Moisture Meters & Mapping – We measure and map moisture levels across surfaces to understand the full extent of water damage.
  • Salts Analysis Testing – Chemical analysis distinguishes mains water leaks from heating system leaks and penetrating dampness.
  • System Pressure Testing – We isolate and pressurise heating circuits, mains pipes, and underfloor loops to confirm leaks and verify repairs.

Why Devon Property Owners Choose Devon Leak Detection

With over 15 years of experience in leak detection, we've built a reputation for accuracy, professionalism, and genuine care for our customers' properties across Exeter, Plymouth, Torquay, and the wider Devon area.

Local Knowledge Across Devon

We understand Devon properties—from Victorian terraces in Exeter to modern estates in Newton Abbot, coastal homes in Exmouth and Dawlish, rural farmhouses on Dartmoor, and period properties in Totnes and Sidmouth. Different building types present different challenges, and we're experienced with them all.

Non-Invasive First

We always try to find the leak without causing damage. Our equipment allows us to see through walls and floors, so we only expose pipework when absolutely necessary and only in the precise location needed.

High Success Rate

We locate the leak on the first visit in over 95% of cases. Our combination of experience and technology means fewer repeat visits, less disruption, and faster resolution for you.

Insurance-Ready Reports

If you're claiming on your home insurance, we provide detailed trace and access reports that meet insurers' requirements. Our documentation includes everything needed to support your claim.

Qualified Engineers

Our team are trained leak detection specialists—not general plumbers who occasionally trace leaks. This focus means we invest in the best equipment and stay current with detection techniques.

Clear, Honest Advice

We explain what we find in plain English, not jargon. If a leak turns out to be something we can't help with, we'll tell you and point you in the right direction rather than trying to sell you something you don't need.

What Our Customers Say About Devon Leak Detection

Don't just take our word for it—here's what homeowners and businesses across Devon have said about our service.

We'd had a damp patch in our hallway for months and two different companies had failed to find the cause. Devon Leak Detection came out and within a couple of hours had traced it to a pinhole leak in a pipe under the floor. Brilliant service and saved us from having the whole floor lifted.

JH
James H. Exeter

Our water bills had been creeping up for a year before we finally called. Turned out there was a leak on the mains pipe running under our driveway. The engineer found it quickly and we only needed to dig in one small area. Very impressed with the professionalism.

ST
Sarah T. Tiverton

Needed a trace and access report for our insurance company after finding water damage in our bathroom. The report was thorough and the claim went through without any problems. Would definitely recommend to anyone dealing with leak-related insurance issues.

MC
Michael C. Plymouth

Our underfloor heating kept losing pressure and our plumber couldn't work out why. These guys pressure tested each loop and found a leak in a pipe joint that had failed. Explained everything clearly and the written report was very detailed. Really helpful team.

ER
Emma R. Newton Abbot

I run a small B&B near Torquay and had water appearing in a guest room ceiling. They came out the next day, found the leak above in the bathroom pipework, and I had the repair done the same week. Minimal disruption to my business—exactly what I needed.

PW
Patricia W. Paignton

Had been topping up our boiler every few days for weeks. The engineer used thermal imaging and found a leak in a pipe buried in the wall. Really glad we called—we were about to start pulling up floors in completely the wrong place!

Frequently Asked Questions About Devon Leak Detection

Here are answers to some of the questions we're asked most frequently by customers across Devon.

Will you need to make holes in my walls or floors?
In most cases, no. Our equipment allows us to locate leaks through walls, floors, and ceilings without causing damage. If access is needed to confirm a leak or enable repair, we'll discuss this with you first and only create the smallest opening necessary.
Is leak detection covered by home insurance?
Many home insurance policies include "trace and access" cover, which pays for the cost of finding a leak and accessing it for repair. Check your policy documents or call your insurer to confirm. We provide detailed reports that meet insurers' requirements.
How long does a typical investigation take?
Most residential investigations are completed within 2 to 4 hours. More complex commercial properties or multiple leak sources may take longer. We'll give you a realistic time estimate when we book your appointment.
Do you carry out repairs once the leak is found?
We specialise in leak detection rather than plumbing repairs. Once we've located the leak, we'll explain what's needed to fix it and can recommend trusted local plumbers or heating engineers if you don't have your own. Some straightforward repairs can be arranged separately.
What areas does Devon Leak Detection cover?
We cover all of Devon including Exeter, Plymouth, Torquay, Paignton, Newton Abbot, Barnstaple, Tiverton, Exmouth, Bideford, Ilfracombe, Sidmouth, Dawlish, Teignmouth, Totnes, Crediton, Honiton, Okehampton, Tavistock, Ivybridge, Kingsbridge, Salcombe, Dartmouth, and all surrounding villages and rural areas. We also cover all of Cornwall. If you're unsure whether we cover your location, just give us a call.
Can Devon Leak Detection find leaks in underfloor heating systems?
Yes, underfloor heating leaks are one of our specialities. We can pressure test individual loops, use thermal imaging to identify problem areas, and trace the exact leak location so repairs can be made with minimal floor disruption.
What should I do if I think I have a leak?
First, check your water meter—if it's turning when no water is being used, you likely have a leak. Note down any damp patches, unusual sounds, or changes in water pressure. Then give us a call and we'll talk through the situation and advise on next steps.
