Leak Detection Cost in Dubai — Realistic Prices and What Affects Them

If you suspect a hidden water leak in your Dubai home, the first thing most people want to know before calling anyone is what it’s going to cost. The answer depends on a few specific factors — the type of leak, where it is, and how difficult it is to locate. But unlike most articles that leave it at that, this one gives you real numbers.

The short version: professional leak detection in Dubai typically costs between AED 300 and AED 1,500 depending on the complexity of the job. Most residential detections fall in the AED 400 to AED 800 range. What follows explains what drives the price and what you’re actually paying for.

Leak Detection Prices in Dubai — What Jobs Actually Cost

• Basic assessment and pressure test: AED 300 – 500. A technician visits, checks visible signs of moisture, and runs a pressure test on your water supply system to confirm whether a leak is present and roughly where it is. For simple, accessible leaks — a leaking pipe joint under a sink, a visible drip at the water heater — this is often all that’s needed before proceeding to the repair.
• Acoustic leak detection: AED 400 – 700. Sensitive listening equipment is used to locate the sound of water escaping a pressurized pipe through walls, floors, or ceilings. Effective for most concealed supply line leaks in residential properties.
• Thermal imaging inspection: AED 500 – 800. A thermal camera detects temperature differences on wall and floor surfaces caused by moisture — cooler areas where water is present show up distinctly. Particularly useful for hot water line leaks and leaks inside walls where acoustic detection is harder to pinpoint.
• Combined acoustic and thermal detection: AED 600 – 1,000. Used when the leak is concealed behind tiles, inside ceiling voids, or in a location where one method alone isn’t sufficient to pinpoint it accurately. Most hidden leaks in older Dubai apartments are found this way.
• Tracer gas detection: AED 800 – 1,500. A harmless gas is introduced into the pipe system. It escapes at the leak point and is detected at the surface by a sensor. Used for very small leaks that acoustic and thermal methods can’t locate precisely — particularly in pipes buried under concrete or running through inaccessible building cavities.
• Under-slab or underground leak detection: AED 900 – 1,800+. Leaks beneath the concrete floor slab or in underground supply lines require specialised acoustic or tracer gas equipment calibrated for detection through concrete. These are the most time-intensive jobs and carry the highest detection cost.
• CCTV drain camera inspection: AED 400 – 700. Used specifically for drainage system problems — cracked pipes, collapsed sections, root intrusion — rather than supply line leaks. Different equipment from leak detection tools.

These are realistic ranges based on what jobs cost in Dubai. The final quote depends on what the technician finds on arrival and how much time and equipment the job requires. Any reputable company gives you a firm price after the initial assessment, before any advanced detection work begins.

What Makes One Job More Expensive Than Another

Where the Leak Is Located

An exposed leak — dripping pipe under a sink, leaking joint at the water heater — takes minutes to confirm and costs the minimum. A leak somewhere inside a tiled wall in a bathroom that shares pipework with three other rooms in a high-rise apartment is a different job entirely. The harder it is to access and isolate the leak, the more time and equipment the detection requires.

Underground and under-slab leaks are the most expensive to detect because the pipe is buried in concrete. The equipment needs to be sensitive enough to pick up the leak signal through significant material. In Dubai, slab leaks are more common than in many other cities because of the combination of ground movement during extreme heat and the high pressure at which water is delivered to buildings.

The Type of Pipe and System

Rigid copper pipes carry sound well, which makes acoustic detection faster and more accurate. PPR and PEX plastic pipes — which are standard in most Dubai buildings constructed in the last 15 years — transmit sound differently, and the leak signal can travel along the pipe length in a way that makes precise location harder. This doesn’t make detection impossible, but it can mean the job takes longer and requires combining methods.

The size and complexity of the property also matters. Locating a leak in a one-bathroom apartment with a straightforward plumbing layout is a shorter job than the same task in a large villa with multiple bathrooms, an outdoor irrigation system, a rooftop storage tank, and pipework running through different floor levels.

How Obvious the Signs Are

A damp patch directly below a bathroom means the leak is probably in the bathroom above it — narrowing the search area significantly. A rising DEWA bill with no visible damp anywhere means the leak could be anywhere in the supply system, which requires a more systematic approach: pressure-testing sections of the system to isolate which part is losing pressure, then using detection equipment within that section. More investigation time means higher cost.

Why Detection Costs Less Than the Alternative

The reason professional leak detection is worth paying for comes down to what happens without it. A plumber without detection equipment who needs to find a hidden leak has one option: open the wall or floor where they think it might be and look. If they’re right, one section gets opened. If they’re wrong — which happens — another section gets opened. Each section that gets opened means tiling, plastering, or flooring that needs to be restored.

In Dubai’s typically tiled bathrooms and kitchens, restoration after exploratory opening isn’t cheap. Matching existing tiles is often difficult or impossible, which means replacing a larger area than what was opened. A professional detection that costs AED 600 and pinpoints a leak to within 20 centimetres saves the cost of opening and restoring multiple wall sections that might total AED 3,000 to 5,000 — plus you’ve already paid for repair work that didn’t fix the leak.

There’s also the ongoing cost of an undetected leak. A pinhole leak in a supply line can lose hundreds of litres per day, which adds up on a DEWA bill over weeks or months before the damage becomes visible. By the time a damp patch appears on a ceiling, the leak has usually been running long enough to cause structural damage that costs considerably more to repair than the leak itself would have.

Supply Line Leaks vs. Drainage Leaks — Different Problems, Different Methods

These two types of leaks behave differently and require different detection approaches, which is worth understanding before you call.

A supply line leak is in a pressurized pipe — the pipes that bring water to your taps, showers, and appliances. Because these pipes are always under pressure, they leak continuously whether or not water is being used. The signs are a water meter that moves when everything is turned off, a DEWA bill that’s higher than expected, or damp that appears without any obvious source. Acoustic and thermal detection, or tracer gas, are used to find these.

A drainage leak is in a non-pressurized pipe — the pipes that carry wastewater away. These only show signs when water is being used: a damp patch on a ceiling that appears after someone showers, a sewer smell, or visible moisture around a drain pipe. CCTV camera inspection is typically used here because the problem is usually a cracked or misaligned joint rather than a pinhole in a pressurized pipe.

Telling a plumber which type of leak you suspect — or describing what you’ve noticed and when — helps them arrive with the right equipment and reduces the time spent on the job. Our leak detection service covers both types, and we’ll identify which kind of leak you’re dealing with during the initial pressure test assessment.

Insurance and Leak Detection in Dubai

Many home contents and building insurance policies in the UAE include what’s called “trace and access” cover. This is specifically designed to cover the cost of professionally locating a hidden leak and the physical access work needed to reach the pipe — opening a wall section, for example. It typically does not cover the pipe repair itself or the reinstatement of the surfaces afterwards, though some policies do include these.

If you have home insurance, check your policy for trace and access cover before paying for detection out of pocket. If it’s covered, you’ll need a professional detection report documenting the location and cause of the leak — which is something a proper detection visit produces as standard. A plumber who simply opens walls and fixes pipes without documentation won’t provide what your insurer needs to process the claim.

Frequently Asked Questions

My DEWA bill has gone up but I can’t see any damp anywhere. Is that definitely a leak?

A rising water bill without visible damp is one of the most common signs of a supply line leak — particularly an underground or under-slab leak where the water is escaping into the ground rather than into the building fabric. The best way to check is to turn off all water-using appliances and taps and watch the water meter for 30 minutes. If the meter moves, water is leaving the system somewhere. That confirms a leak even if there’s no visible sign of it.

Do I need a specialist for hidden leaks, or will any plumber do?

For a visible, accessible leak — dripping tap, leaking joint under a sink — a standard plumber is fine. For a leak you can’t see, a plumber without detection equipment has no option other than opening walls and floors speculatively. The detection equipment that locates hidden leaks non-invasively — acoustic sensors, thermal cameras, tracer gas kits — costs tens of thousands of dirhams and requires training to use correctly. A specialist with this equipment will find the leak faster, with far less surface damage, and at lower total cost than exploratory opening.

What’s the difference between a supply line leak and a drainage leak?

A supply line leak is in a pressurised pipe, so it runs constantly regardless of whether you’re using water. You’ll notice it in your DEWA bill or from damp that doesn’t correspond to specific water use. A drainage leak only occurs when water is being used and draining — damp that appears during or after showers, for example, or a sewer smell from a specific drain. They need different detection methods, and describing your symptoms accurately helps the technician arrive prepared.

Does home insurance in the UAE cover leak detection?

Many policies include trace and access cover, which pays for finding the leak and physically accessing the pipe. It generally doesn’t cover the repair of the pipe itself or restoring the surfaces that were opened, though policies vary. Check your policy wording specifically for “trace and access” — if it’s there, you’ll need a professional detection report to support the claim, which a proper inspection provides.

How long does a leak detection visit take?

A straightforward residential leak detection — pressure test, acoustic scan of the relevant area, confirmation of leak location — typically takes one to two hours. More complex situations, like locating an under-slab leak in a large villa, can take three to four hours or require a follow-up visit if tracer gas is needed. We give you a realistic time estimate when you call and describe the situation.

Why are slab leaks particularly expensive to detect and repair in Dubai?

Detection through concrete requires more sensitive equipment than detection through walls, and the signal can be harder to isolate when the pipe runs under a large poured slab. On the repair side, accessing the pipe means either cutting into the slab — which is disruptive and expensive to reinstate — or re-routing the pipe through the walls above, which avoids the concrete but involves running new pipework. The approach depends on where the leak is and what the existing plumbing layout allows. We assess both options and explain the costs before any work starts.
