How to detect a leak yourself
Simple methods to confirm the presence of a leak before calling a professional.
Water meter test
- 1.Turn off all taps and water-using appliances in your home
- 2.Note the exact reading on your water meter
- 3.Wait 2 hours without using any water
- 4.Check whether the meter has moved: if so, there is a leak
Reliable for confirming a leak
2 hours
Food colouring in the toilet cistern
- 1.Get some food colouring (red or dark blue)
- 2.Add a few drops into the toilet cistern
- 3.Wait 30 minutes without flushing
- 4.If the bowl changes colour, the cistern has a silent leak
Very effective for toilet leaks
30 minutes
Visual inspection
- 1.Check the seals around taps, shower and bath
- 2.Look for damp patches on walls and ceilings
- 3.Inspect under sinks and behind toilets
- 4.Watch for mould traces or blistering paint
Detects visible leaks
15-30 minutes
Why DIY detection fails
A leak that is not precisely located can cause considerable damage. Domestic methods have their limits.
Concealed pipes
Most pipes run through walls, floor slabs or false ceilings. Without specialist equipment such as thermal imaging, inspection is impossible.
Gradual leaks
A micro-leak can lose litres per day without any visible trace. Only acoustic detection or tracer gas can locate it before it causes structural damage.
Misidentified source
Water follows gravity and the path of least resistance. A damp patch may appear several metres from the actual leak. Without technology, you risk breaking open the wrong spot.

How much does leak detection cost in Luxembourg?
The price of leak detection in Luxembourg starts at €149 excl. VAT (approximately €177 incl. VAT). The final price depends on the complexity: number of technologies used, area to inspect and accessibility of the pipes.
Our leak detection rates:
- Standard search (thermal imaging): from €149 excl. VAT
- In-depth search (acoustic + thermal): from €249 excl. VAT
- Complex search (tracer gas included): from €349 excl. VAT
Each rate includes:
- Travel across all of Luxembourg
- Detailed location report with photos
- Repair recommendations
- Detailed invoice for your insurance
A precise quote is provided after a telephone description of your situation.
What methods do you use to detect leaks?
We use three complementary technologies: infrared thermal imaging to visualise temperature differences, acoustic detection to listen for micro-leaks in pipes, and tracer gas for the most complex cases.
Our three detection technologies:
1. Infrared thermal imagingVisualises temperature variations caused by water in walls, floors and ceilings. A fast and entirely non-destructive method.
2. Acoustic detectionUltra-sensitive sensors amplify the sound of escaping water, even through concrete. Pinpoint accuracy to the centimetre.
3. Tracer gasAn inert, harmless gas is injected into the pipe. Surface sensors detect the exact point where the gas escapes, revealing the leak.
The method chosen depends on the type of leak and the configuration of your installation.
Is leak detection covered by insurance?
Yes, in most cases. Leak detection is covered by the water damage guarantee of your home insurance in Luxembourg. We provide a detailed report with photos and precise location, accepted by all insurance companies.
Insurance coverage depends on your policy:
- Standard home insurance: generally covers both the search and repair in case of water damage
- Excess: varies by policy (typically between €150 and €500)
- Claim: must be reported within 5 working days
Our leak detection report is designed to facilitate your insurance claim:
- Precise location with thermal images
- Technical description of the leak
- Estimate of necessary repairs
- Detailed invoice meeting insurer requirements
How long does a leak detection take?
A standard leak detection takes between 1 and 2 hours. For complex cases involving multiple technologies or a large area, allow 2 to 4 hours. We provide a time estimate when booking the appointment.
Duration depends on several factors:
- Simple search (localised leak, easy access): 1 to 1.5 hours
- Standard search (leak in a wall or floor): 1.5 to 2.5 hours
- Complex search (buried pipe or multi-storey building): 2 to 4 hours
Factors affecting duration:
- Building area to inspect
- Accessibility of pipes
- Number of water points to check
- Construction type (old vs. new build)
We do not leave until the leak is found. If one method is not enough, we switch to the next at no extra cost within the quoted price.
How can you detect a hidden leak in a wall or floor?
To detect a hidden leak, watch for signs: damp patches, blistering paint, water meter turning with taps closed. Only a professional equipped with thermal imaging and acoustic detection can precisely locate the leak without breaking anything.
Tell-tale signs of a hidden leak:
- Growing damp patches on a wall or ceiling
- Blistering paint or peeling wallpaper
- Persistent musty smell in a room
- Water meter turning with all taps closed
- Unexplained rise in water bill
Breaking open a wall blindly worsens the damage and costs. Our technologies see through walls:
- Thermal imaging detects the damp zone without contact
- Acoustic detection locates the leak point to the centimetre
- Tracer gas identifies leaks on buried pipes
Result: a minimal opening, targeted exactly at the leak.
