Leak Detection in Ealing, Hillingdon, & West London — 24/7, No Callout Fee

A hidden leak won't fix itself, and every day it goes untraced it does more damage. Our leak detection service finds concealed and hidden water leaks fast and accurately across Ealing, Hillingdon and West London, using non-invasive equipment that pinpoints the source without tearing up your floors and walls to look for it. Left untreated, a hidden leak causes further structural damage the longer it runs — so the sooner we accurately locate it, the better. Available 24 hours a day, with a one-hour average response.

There's no callout charge — you only pay for the work. Our experienced plumbers and leak detection engineers can trace the leak only, if you have a plumber ready to carry out the repair, or find and fix it in the same visit.

Call now on 07494 691 692 — 24 hours a day, 7 days a week.

 

 

Signs You Have a Hidden Leak

Concealed leaks are difficult to spot because the water damage often appears a long way from the leak itself. The signs to watch for:

 

• A high water bill with no explanation — often the first and clearest sign of a hidden leak
• A damp patch, stain or blistering paint on a wall, ceiling or floor
• A musty smell in a particular room that doesn't shift
• The sound of running water when all taps and appliances are off
• Warm patches on the floor — a sign of a leak on the hot feed or a central heating pipe
• Boiler pressure dropping repeatedly and needing topping up
• Reduced water pressure with no obvious cause
• Cracked or lifting floor tiles where water has got beneath them

If you've spotted any of these, the sooner the leak is traced the less damage it does — and the cheaper it is to put right. Left untreated, a slow leak behind a wall can go unnoticed for months, rotting joists and ruining plaster, and in the worst cases causing damage to the structure of the building itself.

 

Our Leak Detection Process — Minimal Damage, Maximum Accuracy

 

The old way of finding a leak meant guessing at the location and digging or cutting until you found it. We don't work that way. As leak detection specialists, our process is non-invasive: we accurately locate the leak first, with minimal damage to your property, so any repair work is targeted rather than exploratory.

We use several methods of leak detection, and often more than one on the same job, working from the least intrusive upwards:

 

• Acoustic listening devices — sensitive equipment picks up the sound of water escaping a pressurised pipe, even through concrete, tile or plaster
• Thermal imaging cameras — infrared cameras reveal the temperature differences a leak creates behind a surface, mapping the affected area without touching it
• Tracer gas — a safe gas is introduced into the pipework and detected where it escapes, ideal for pinpointing very small or slow leaks
• Fluorescent dye — introduced into the system to make a leak visible under UV light, useful on pools, tanks and visible pipework
• Endoscopic cameras — a small borescope camera inspects cavities, ducts and voids where a leak is suspected but can't be seen
• Moisture meters and pipe tracing — to map pipe routes and confirm the extent of water spread

 

Having the full range of detection equipment matters, because no single method finds every leak. A leak that acoustic listening devices can't hear may show up instantly on thermal imaging cameras, and vice versa. We bring all of it, so we don't have to come back.

 

Leaks We Trace and Repair

 

Concealed pipe leaks

Leaks on pipework buried in walls, under floors or above ceilings — the hardest to find and the most damaging when left. Tracing hidden leaks in domestic plumbing systems is the core of what we do.

 

Central heating leaks

If your boiler pressure keeps dropping and needs topping up, you almost certainly have a leak somewhere in the system. We trace leaks in central heating systems — radiator pipework, valves and buried heating circuits, including under solid floors.

 

Underground water leaks & water main leaks (water meter checks)

A leak on your incoming water supply — between the water meter and the house — can waste an enormous amount of water and won't show inside. Underground water leaks are easy to miss until the bill arrives. We carry out water meter checks to confirm a supply-side leak, then locate underground water leaks along the run so the pipe can be dug up in one place rather than several.

 

Under-floor and slab leaks

Leaks beneath a concrete slab or solid floor are among the most difficult to locate without specialist equipment — and the most expensive to get wrong. Thermal imaging and acoustic detection let us pinpoint a slab leak precisely, so the floor is only opened where it needs to be.

 

Bathroom and wet room leaks

Water escaping through failed sealant, grout or a shower tray often looks like a plumbing leak but isn't. We identify whether the problem is pipework or waterproofing, so you're not paying to chase a leak that a re-seal would fix.

 

Swimming pool leaks

A dropping pool level usually means a leak in the pool structure or its circulation pipework. We can help trace a suspected swimming pool leak using the same acoustic, dye and pressure-testing methods we use elsewhere.

 

Leak Detection for Insurance Claims ("Trace and Access")

Most home and building insurance policies include what's called "trace and access" cover — they'll pay to locate a leak and access the damage, as well as for the resulting repairs. But to claim, you usually need a professional leak detection report documenting the leak and its cause.

We provide written leak detection reports suitable for building insurance claims, setting out what we found, where, and the method used. Acting quickly also limits further water damage while the claim is processed. If your insurer has asked for evidence before they'll process a claim, this is exactly what they need — call us and mention it's for an insurance claim when you book, so we bring the right documentation.

 

Detection-Only and Trade Callouts

Not everyone needs us to carry out the repair. We work regularly with other plumbers, builders and property managers who need a leak located quickly so their own team can fix it. If you already have someone on the job and just need the leak pinpointed, we offer detection as a standalone service.

Equally, if you'd rather we handled the whole thing — trace the leak and repair it in the same visit — our engineers are fully qualified plumbers, not just leak locators, so there's no need for a second appointment or a second trade.

 

Experienced Leak Detection Engineers

We're not a call centre that subcontracts the work — we're a local leak detection company with our own experienced plumbers and leak detection specialists working across West London every day. Every engineer is a member of the Chartered Institute of Plumbing and Heating Engineering (CIPHE), the professional body for the UK plumbing and heating industry, and all work is fully insured and comes with a six-month warranty.

Because our leak detection engineers are fully qualified plumbers as well, we can move straight from finding the leak to fixing it — on domestic plumbing systems, central heating systems and the incoming water supply alike. Our specialist leak detection equipment lets us locate leaks other plumbers can't, and we work for homeowners, landlords and commercial clients across the area.

 

Ealing Leak Detection

We're based in Ealing, which makes us the fastest local option for leak detection across the borough — Ealing includes West Ealing, South Ealing, Acton, Hanwell and Greenford, all of which we cover. Ealing's older housing stock, with a lot of original buried pipework and solid floors, throws up exactly the kind of concealed and slab leaks our equipment is built to find.

 

Leak Detection in Hillingdon & West Drayton

We cover Hillingdon, Uxbridge, West Drayton, Hayes, Ickenham and Ruislip for both emergency and planned leak detection, domestic and commercial. Wherever you are in the borough, we're rarely far away.

 

Leak Detection Across West London

Beyond Ealing and Hillingdon, we cover the wider West London area and out towards Buckinghamshire and Surrey — Chiswick, Hammersmith, Fulham, Kensington & Chelsea, Richmond, Twickenham, Teddington, Staines, Egham, Chalfont St Giles, Chesham, Amersham and more. See the full list below or check our coverage map.

 

Homeowners, Landlords & Commercial Properties

For homeowners, a hidden leak means rising bills and mounting damage. As your local emergency plumber we locate it fast and accurately, and can repair it there and then.

For landlords and letting agents, we trace leaks between flats and in communal areas, provide the documentation you need for insurers or leaseholders, and work around tenant access.

For commercial properties, we find leaks with minimal disruption and, wherever possible, without closing you down. If tracing or fixing the leak needs further access, we'll set out your options before doing anything.

 

Leak Detection — Frequently Asked Questions

 

How much does leak detection cost?

There's no callout charge — you only pay for the work carried out. The cost depends on how much tracing the leak takes, and we'll be clear with you about that before we start. If the leak needs repairing once found, we'll quote that separately so you can decide whether we carry it out or your own plumber does.

 

Will you damage my walls or floors finding the leak?

No — that's the point of what we do. Our methods are non-invasive: acoustic detection, thermal imaging and tracer gas let us pinpoint the leak first, so any access needed for the repair is minimal and in the right place, rather than exploratory.

 

How quickly can you come out?

Our average response is one hour across Ealing and the immediate surrounding areas. We operate 24 hours a day, 7 days a week, including bank holidays.

 

Can you provide a report for my insurance claim?

Yes. Most policies include "trace and access" cover but require professional evidence of the leak. We provide written reports suitable for insurance claims — mention it's for a claim when you book.

 

My boiler pressure keeps dropping. Is that a leak?

Very often, yes. If you're repeatedly re-pressurising your boiler and there's no visible drip, there's likely a leak somewhere in the central heating pipework — sometimes buried under a floor. We trace heating leaks specifically.

 

Do you find leaks on the water main / outside supply?

Yes. We carry out water meter checks to confirm a supply-side leak and trace its position along the run, so any excavation is limited to one spot rather than digging up the whole route.

 

Can you just find the leak and let my own plumber fix it?

Absolutely. We offer detection as a standalone service and work regularly with other trades. Or we can find and fix it in one visit — whichever suits you.
