🔍 Quick Self-Assessment: Do You Have an Underfloor Heating Leak?
Before you call, check these warning signs. In my 30+ years tracing leaks across Cornwall and Devon, I've seen the same patterns time and again. Here's how to spot trouble early:🚨 Immediate Action Needed If You Notice:
- Pressure drop on your boiler gauge - the most reliable indicator
- Wet or damp patches appearing on floors, especially after the heating's been on
- Cold spots in areas that should be warm
- Musty smells or visible mould growth
- Unusual noises - gurgling, hissing, or bubbling sounds
- Higher water bills without increased usage
🔧 Why Underfloor Heating Systems Leak
After three decades with my ear to the ground (literally), I've traced thousands of heating leaks. Here's what really causes them, not the waffle you'll read elsewhere:The Big Three Culprits
1970s-80s Copper Nightmare
The chemistry doesn't lie: Thin copper pipes laid directly in concrete react with alkali, creating pinhole leaks. I see this weekly in older Cornwall properties. One leak usually means more are coming.Poor Installation Joints
The truth about fittings: Every joint is a potential failure point. Modern systems use continuous PEX loops up to 110 metres - far fewer joints, far fewer problems.Accidental Damage
The renovation risk: Drill hits, screw punctures, and renovation work account for 30% of the emergency calls I get. Always check pipe routes before any work.The Cornwall Weather Factor
Our coastal climate brings unique challenges. Freeze-thaw cycles stress pipes differently than inland areas. High humidity from sea air can mask early leak signs. I've learned to read our local conditions - it's why central heating leak detection in Cornwall requires local expertise. From professional leak detection specialists in Falmouth dealing with maritime properties to Penzance underfloor heating leak experts handling exposed coastal homes, location knowledge makes the difference. I've traced leaks in Camborne's mining heritage properties and Newquay's holiday accommodation - each area has distinct challenges.🛠️ DCI's 6-Step Underfloor Leak Detection Process
This isn't guesswork. It's a proven system I've refined over decades. Every step builds on the last, getting us closer to your leak with surgical precision:Initial Assessment & System Isolation
First job: establish if it's actually your underfloor heating. I test each zone separately using pressure gauges. Could be water supply pipes, could be drainage. No point chasing the wrong system. This acoustic leak detection methodology prevents wasted time and money.Thermal Imaging Survey
My FLIR camera sees what eyes can't - temperature differences that reveal pipe routes and leak locations. Hot spots show where heated water is escaping into surrounding areas. This thermal imaging leak detection technology is game-changing for underfloor heating systems.Acoustic Detection
High-frequency microphones pick up the sound of water escaping under pressure. Different pipe materials, different frequencies. After 30+ years, I can hear a pinhole leak through concrete. This method works brilliantly for underground water leak detection in all floor types.Tracer Gas Investigation
When thermal and acoustic aren't enough, I inject harmless hydrogen-nitrogen gas. It escapes through any opening and gets detected at surface level - works through wood, tile, even thick concrete. This tracer gas leak detection pinpoints leaks to within centimetres.Precise Location & Access
Now I know exactly where to dig. Trace and access done right means minimal floor damage. I mark the spot, explain what's needed, then make the smallest opening possible. This approach satisfies insurance requirements perfectly.Repair & System Test
Leak fixed, system pressure-tested, everything back to full working order. I use manufacturer-approved repair methods to protect your warranty. Then we test the whole system - no comeback surprises. Full plumbing leak services from detection to completion.💧 DCI Difference: Water Conservation Focus
Every hidden leak wastes thousands of litres. In drought-conscious Cornwall, that matters. I'm not just fixing your heating - I'm stopping unnecessary water waste. It's about doing right by our community and environment.💰 Underfloor Heating Leak Detection Costs
Straight talk on pricing. Unlike the "from £X" nonsense you see elsewhere, here are the real factors that affect your bill:Property Size & Access
Bungalow with easy manifold access? Straightforward. Three-storey house with buried manifold? More complex. Size and accessibility directly impact time needed.System Type & Age
Modern PEX systems with clear documentation? Quick to trace. 1980s copper with no plans? Needs more detective work. Age and documentation matter.Floor Type & Thickness
Tiles over screed need different techniques than engineered wood. Thick concrete takes longer to scan. Floor construction affects methodology and time.Leak Complexity
Single leak in accessible area? Quick fix. Multiple leaks or deep burial? More involved. Complexity affects both detection time and repair scope.Insurance & Trace and Access Coverage
Good news: Most home insurance includes trace and access cover for underfloor heating leaks. This typically covers both my detection fees and necessary access work. Always check your policy first - I provide full documentation for claims. I work directly with most major insurers. No upfront payment if your policy covers it - I claim directly, you get the repair without financial stress.🏠 Water vs Electric: Different Systems, Different Problems
Not all underfloor heating is the same. Here's what I deal with across Cornwall and Devon:Wet (Hydronic) Systems
What leaks: Water-filled pipes, manifold connections, pump units Detection methods: Pressure testing, thermal imaging, tracer gas Common in: New builds, extensions, whole-house heatingElectric Systems
What fails: Cable damage, joint failures, control systems Detection methods: Thermal imaging, electrical fault finding Common in: Bathrooms, conservatories, retrofit installations🛡️ Preventing Future Underfloor Heating Leaks

Saltash, CornwallCovering Cornwall & DevonFrequently Asked Questions Underfloor Heating Leaks
How long does underfloor heating leak detection take in Cornwall?
Most jobs take 2-6 hours depending on system complexity and property size. My 30+ years of experience means I can often locate leaks faster than competitors who quote 4-8 hours. Complex 1980s copper in concrete? Half a day maximum. Cornwall’s older properties often need more detective work due to poor original documentation.
What happens if you find multiple leaks in my underfloor heating?
Common in 1970s-80s Cornwall properties with copper pipes in concrete. I prioritise repairs by severity: major leaks stopped immediately, minor ones assessed for cost-effectiveness. Sometimes replacing entire zones is cheaper than multiple small repairs. I provide a comprehensive report showing all leak locations, repair options, and cost comparisons. Most insurers cover multiple leaks under single claims when properly documented.
Why do 1970s-80s Cornwall properties have more underfloor heating leaks?
Chemistry doesn’t lie. Thin copper pipes laid directly in concrete react with alkali, creating pinhole leaks. This was common practice in Cornwall developments between 1975-1985. One leak usually means more are coming. I’ve tracked this pattern across hundreds of jobs. Modern systems use PEX pipes with protective barriers – completely different chemistry, far fewer problems.
What's the difference between wet and electric underfloor heating leak detection?
Huge difference. Wet systems: pressure testing, thermal imaging, tracer gas injection. Electric systems: thermal scanning, electrical fault finding, cable continuity testing. Wrong diagnosis wastes hours and money. I identify your system type within minutes – competitors often guess. Wet systems show temperature drops, electric systems show heating element failures. Completely different approaches needed.
Should I call emergency or standard service for underfloor heating leaks?
Emergency (same-day): visible water damage, complete system failure, significant pressure drops, property flooding risk. Standard (next-day): suspected leaks, gradual pressure loss, uneven heating, preventative checks. Emergency callouts cost 50% more but prevent major damage. I’ve seen £500 leaks become £5,000 problems when ignored overnight.
How do you detect leaks under thick concrete floors in Cornwall and Devon?
Critical factor competitors ignore. Pre-1980: mostly copper pipes, often unlagged, expect multiple leaks. 1980-2000: mix of copper and early plastic, better documentation. Post-2000: modern PEX systems, detailed plans available. I adjust detection methods based on building era. Victorian conversions need special care – I know which Cornwall builders cut corners and which built to last.
What environmental impact do underfloor heating leaks have?
Hidden leaks waste 50-200 litres daily. In drought-conscious Cornwall, that’s environmentally irresponsible. I’m not just fixing your heating – I’m stopping unnecessary water waste. Average hidden leak wastes 15,000 litres yearly. That’s enough water for a family of four for 6 weeks. Every leak I find helps protect Cornwall’s water resources for future generations.
