📞 Call Now: 07822 025 911
Here’s the truth about water leaks: A pinhole leak loses about 170 gallons daily. That’s £620 yearly down the drain, plus whatever damage it’s quietly causing behind your walls. After 30+ years finding leaks across Cornwall and Devon, I’ve seen too many “small” leaks turn into five-figure disasters.
At DCI Leak Detection, we use cutting-edge technology to find leaks without ripping apart your home. Think keyhole surgery for your pipes – we get in, find the problem, and get out with minimal fuss.
💧 Why Water Leak Detection Matters More Than You Think
Every property in Cornwall and Devon faces unique water leak challenges. Our coastal climate, ageing infrastructure, and varied soil conditions create the perfect storm for pipe problems. Here’s what I’ve learned after four decades on the tools:
External supply pipe failures account for 30% of our callouts. Whether it’s a mains water leak or internal pipework, early detection saves thousands in repair costs and prevents structural damage.
The Real Cost of Ignoring Leaks
🔍 Our Water Leak Detection Process: How We Find What Others Miss
Finding water leaks isn’t guesswork – it’s science. We combine four proven detection methods to guarantee results. Here’s exactly how we track down your leak:
Whether it’s a residential property or commercial building water leak detection for your business, our process remains thorough and systematic.
Initial Assessment
We map your pipework and identify high-risk areas. Quick pressure tests reveal if you’ve got an active leak.
Acoustic Detection
Sensitive ground microphones pick up leak sounds through concrete, tiles, even granite. Water escaping under pressure creates distinct frequencies.
Thermal Imaging
Our FLIR cameras spot temperature differences caused by water flow. Perfect for underfloor heating leaks and hot water pipes.
Tracer Gas
For stubborn leaks, we use safe hydrogen/nitrogen mix that finds even micro-leaks. The gas rises through any material to pinpoint the exact spot.
Moisture Mapping
We trace water’s path using professional moisture meters, ensuring we’ve found the source, not just the symptom.
Leak Located & Marked
We mark the exact leak location with precision. You’ll know precisely where to access the pipe, minimizing damage and repair costs.
🏠 Types of Water Leaks We Detect
Not all leaks are created equal. Each type requires specific detection methods and equipment. Here’s what we commonly find across Cornwall and Devon properties:
From surface issues to deep underground water leaks, we’ve developed specific techniques for every scenario.
| Leak Type | Common Causes | Detection Method | Urgency Level |
|---|---|---|---|
| Mains Water Leaks | Pipe corrosion, ground movement, tree roots | Acoustic correlation, tracer gas | 🔴 Critical – 24hr response |
| Internal Pipe Leaks | Joint failure, frost damage, poor installation | Acoustic listening, thermal imaging | 🟠 High – 48hr response |
| Slab Leaks | Foundation settling, pipe age, water chemistry | Ground microphones, moisture mapping | 🟠 High – Property damage risk |
| Central Heating Leaks | Corrosion, pressure issues, micro-leaks | Thermal cameras, pressure testing | 🟡 Medium – Boiler damage risk |
| Swimming Pool Leaks | Liner damage, pipe cracks, fitting failure | Dye testing, pressure monitoring | 🟡 Medium – Water waste |
🛠️ Advanced Water Leak Detection Technology Explained
Gone are the days of digging up half your garden hoping to find a leak. Modern leak detection is about precision, not destruction. Here’s the kit that makes the difference:
Acoustic Leak Detection
Think of it as a stethoscope for your pipes. Water escaping under pressure creates vibrations we can hear through specialist equipment. Our ground microphones amplify these sounds by 10,000 times – I can literally hear a drip through 3 feet of concrete. Discover how our acoustic leak detection technology pinpoints even the smallest leaks.
Thermal Imaging Cameras
Our FLIR cameras see temperature differences invisible to the naked eye. Hot water leaks show as warm spots; cold water creates cool patches. Particularly brilliant for underfloor heating leak detection where other methods struggle. Learn more about our thermal imaging leak detection capabilities.
Tracer Gas Technology
When acoustic and thermal fail, tracer gas succeeds. We use a 5% hydrogen mix that’s completely safe but incredibly effective. It’ll find leaks losing less than a teacup of water daily. Perfect for those mystery leaks that have other companies scratching their heads. Learn more about our tracer gas leak detection service.
Moisture Meters & Mapping
Professional-grade meters that measure moisture content to 0.1% accuracy. We create a moisture map of your property to trace water’s path back to its source. Essential for insurance claims and preventing future problems.
These combined technologies allow us to tackle everything from swimming pool leaks to complex underground pipe failures with confidence.

Commonly Asked Questions About Water Leak Detection
How accurate is professional leak detection really?
In good hands with proper equipment, we achieve 95% accuracy pinpointing leaks to within 30cm. That’s the difference between removing two tiles or ripping up half your bathroom floor. The 5% uncertainty usually involves multiple leaks or pipes running through solid granite – even then, we’ll narrow it down to a small area.
Can you detect leaks through concrete floors?
Absolutely. Our acoustic equipment hears water movement through up to 4 feet of concrete. The trick is knowing what you’re listening for – a pinhole leak sounds like rice pouring, while a split joint sounds like bacon frying. After 30+ years, I can tell you the leak type just by the sound.
What if my leak only happens sometimes?
Intermittent leaks are often temperature-related – pipes expand and contract, opening hairline cracks. We use pressure testing over time and data loggers that record 24/7. Caught many a “ghost leak” that only appeared when the heating kicked in at 6am.
Will you need to dig up my driveway?
Rarely. We trace external leaks using acoustic correlation – think of it as triangulation using sound. We can pinpoint leaks under tarmac, concrete, even that expensive block paving, without lifting a single stone. Only dig where we need to repair.
How long before I can use my water again?
For detection only – immediately. We don’t need to turn off your water to find leaks (except for pressure testing). If we’re repairing too, most domestic repairs are done within 2-4 hours. You’ll have water back the same day.
Is it cheaper to just replace all the pipes?
Depends on your property. For a 1960s bungalow with accessible pipework, maybe. For a Georgian townhouse with pipes buried in lime plaster walls? You’re looking at £15,000+ and weeks of disruption. Detection and targeted repair usually saves 80% of that cost.
I live in a listed building - can you still help?
Yes, and we’re probably your best option. Listed buildings need non-invasive detection more than anyone. We’ve worked on Grade I listed properties across Cornwall using only thermal imaging and acoustic detection. No drilling, no damage to historic fabric.
My property is only 2 years old - surely I can't have leaks?
New builds actually have higher leak rates in the first 5 years. Poor installation, untested joints, and settlement movement all cause problems. Plus, modern push-fit plumbing can fail if not installed perfectly. Don’t assume new means leak-free.
Does our coastal climate make leaks more likely?
Yes. Salt air accelerates copper pipe corrosion, especially in exposed locations. Temperature swings between summer tourists and winter storms stress pipework. Plus, our acidic moorland water (pH 6.5) eats copper from the inside. Perfect storm for leaks.
Why do I lose more pressure in winter?
Cornwall rarely gets proper freezes, but we get plenty of freeze-thaw cycles. Pipes expand and contract repeatedly, opening micro-cracks. Plus, you’re using more hot water, revealing heating system leaks that summer masked. Book detection before Christmas chaos.
My plumber couldn't find the leak - why would you be different?
Plumbers are excellent at fixing leaks but most lack specialist detection equipment. They rely on experience and educated guesses. We use £50,000+ of detection equipment and do nothing but find leaks all day. It’s like comparing a GP to a heart surgeon.
The water meter is spinning but all taps are off - whose problem?
If the meter itself is faulty, that’s South West Water’s issue. If it’s spinning due to a leak on your property (after the meter), that’s yours. We can quickly determine which with a simple isolation test. Don’t delay – you’re paying for that water.
My water bill has tripled - will they reduce it?
South West Water may offer a one-time leak allowance if you prove you’ve repaired the leak promptly. Get our detection report as evidence. They typically reduce the excess usage by 50%, but only once per property ownership.
What causes most leaks in Cornwall and Devon?
1) Corrosion from acidic water 2) Poor installation of modern push-fit plumbing 3) Ground movement on clay soils 4) Freeze-thaw damage 5) Age – copper pipes last 50-70 years, many properties are reaching that limit.
