A rising water bill with no obvious cause, a damp patch that won't dry out, or a warm strip on the floor that shouldn't be there — these are the classic signs of a hidden leak. We trace it non-invasively wherever we can, working alongside specialist leak-detection kit for the trickier cases, so we find the source with the least disruption to your home. Once we know exactly where it is, we fix it or tell you honestly what's needed. Fully insured, careful work, and documentation your insurer will actually want to see.
A hidden leak rarely announces itself — it shows up as a symptom somewhere else entirely: a bill that's crept up, a patch of damp that keeps coming back, or a floor that's warm in one spot and not another. Finding the actual source without pulling a house apart is the real skill, and it's what we focus on before any digging or lifting starts.
If your water bill has jumped and nothing in the house has changed, an underground supply pipe or a hidden internal leak is the most likely explanation. We start by checking your stopcock and meter — turning everything off and watching whether the meter still ticks over tells us within minutes whether there's a leak and roughly where to start looking.
A damp patch on a ceiling or wall, a warm strip on an otherwise cool floor, or skirting boards that have started to lift are all signs worth taking seriously. Underfloor heating pipes and hot water runs under solid floors are common culprits for warm spots; cold supply pipes tend to show up as damp rather than heat. We read the pattern before we touch anything.
Our first approach on every hidden leak is to narrow the source down without cutting into your home — checking pressure, isolating sections of pipework, and following the physical evidence to build a clear picture of where the leak actually is. Most of the time we can identify the likely area this way before anything gets opened up.
Where a leak is genuinely hidden — under a solid floor, inside a cavity wall, or along a buried supply pipe — we bring in acoustic and thermal-imaging leak-detection equipment to pinpoint it precisely before any opening-up work happens. That means the repair, when it comes, is targeted at the actual leak rather than a guess.
If a hidden leak has caused damage, your home insurance will very likely cover it under escape-of-water — but insurers want evidence, not just a repaired pipe. We document what we find: the likely cause, the location, photos of the leak and the fix, and an itemised invoice describing exactly what was done. That paper trail is exactly what makes a claim straightforward.
Three steps. No surprises.
Tell us what's prompted the call — a bill, a damp patch, a warm floor, a sound of running water you can't place. That helps us bring the right kit and start narrowing things down from the moment we arrive.
We check the stopcock, meter and visible pipework, then use specialist detection equipment where the leak is genuinely hidden. We aim to pinpoint the source before anything gets opened up, so any disruption is targeted, not guesswork.
Once we know exactly where the leak is, we give you a clear price for the repair before starting, document everything for your records or insurer, and either fix it there and then or book the repair in. You get an itemised VAT receipt by email, and you can pay by card on the spot with Stripe Tap to Pay, by bank transfer (BACS), or cash.
Based at 147 Woodfield Road, Crawley RH10 8AD, we trace hidden leaks across Crawley and out into the wider Sussex, Surrey, South London and Kent area — including the older housing stock where hidden leaks are most common. Click any area for full detail on what we cover there.
Not in this list? We also reach Burgess Hill and South London, and most addresses within about an hour of Crawley — call 07884 064809 and we'll confirm we cover you.
A hidden leak and a sudden burst are two ends of the same problem — if a pipe has properly let go, see our burst pipe repair service across Sussex. If you need someone urgently and can't wait, our 24/7 emergency plumber service in Crawley covers it, and if the leak's turned up during or after bathroom work, take a look at bathroom installation in Crawley.
We start with the simple checks — stopcock, meter, visible pipework and the pattern of damp or damage — which often narrows things down on its own. Where the leak is genuinely hidden, under a solid floor or inside a wall, we bring in acoustic and thermal-imaging detection equipment to pinpoint it precisely, so we're not guessing where to open up.
Our aim is always the least disruption possible. Most leaks can be traced non-invasively before anything is opened up, and once we've pinpointed the source, any access we do need is targeted to that spot rather than a wider search. We'll always explain what we need to access and why before we start.
Yes. Escape-of-water damage is covered by most home insurance policies, and insurers want a clear account of the cause, the location and the repair. We document what we find with photos and an itemised VAT invoice describing the fault and the work carried out. We can't submit the claim for you, but we'll give you everything you need to submit it yourself.
It depends on how straightforward the leak is to trace, so we won't quote a fixed figure upfront that might not hold. What we promise is a clear price agreed before any work starts, then you pay for the time on the job plus any parts or specialist equipment needed, with a VAT receipt by email.
We're based at 147 Woodfield Road, Crawley RH10 8AD and cover Crawley (RH10, RH11), Horsham (RH12, RH13), Burgess Hill (RH15), Haywards Heath (RH16, RH17), East Grinstead (RH19), Redhill (RH1), Reigate (RH2), Brighton (BN1-3) and out into Surrey, South London and Kent. If you're within about an hour of Crawley, call us — chances are we cover you.
No — plumbing is our trade, not gas. For anything involving gas appliances, gas pipework or boilers, we'll point you to a Gas Safe registered engineer (gassaferegister.co.uk), because that's the right qualification for that part of the job. If you ever smell gas, don't wait — call the National Gas Emergency Service on 0800 111 999.
The sooner it's found, the less damage and disruption. Call or WhatsApp and we'll talk through what you're seeing.
