Leak Detection Service in Paris — 100% Insurance Covered

You have a damp patch on the wall. Your water bill has doubled for no obvious reason. Or your water meter is spinning even though every tap is off.

You know there's a leak. You just don't know where.

And the solution that comes to mind — knocking down the wall, lifting the tiles — is also the one you're dreading most.

Good news: that's no longer the only option. Professional leak detection locates a leak to within a few centimetres, without touching your walls, without demolishing your bathroom, without turning your apartment into a building site.

Even better: in most cases, the entire cost is covered by your home insurance. We handle the paperwork for you.

How we detect a leak without breaking anything

Acoustic detection

A water leak creates a vibration that travels along the pipe and through the building materials. A professional acoustic sensor picks it up. We place sensors at access points on your water network, and a correlator calculates the exact position of the leak. Accurate to 10 to 30 centimetres. No wall opened. No tiles lifted.

Thermal imaging

Water leaking inside a wall or under a floor changes the surface temperature of the material. A thermal camera reads these differences and shows the damp zone as a colour anomaly. Particularly effective for underfloor heating leaks and leaks behind plasterboard.

Tracer gas

For deep or very slow leaks, we inject a harmless gas mixture into the pipe after isolating the network. The gas rises through the material and escapes at the leak point. A surface detector picks it up with centimetre-level precision.

Is your leak covered by insurance in France?

This is the question most expats and international residents don't think to ask — and the answer is almost always yes.

French home insurance contracts include a guarantee called garantie dégâts des eaux — water damage cover. Under this guarantee, your insurer covers:

• The cost of professional leak detection (plumber, equipment, technical report)
• The cost of making good after the search (replastering, retiling if necessary)
• In many contracts: the water damage itself

The condition: qualified professional + written technical report. That's what Réseau Tubulure provides as standard.

How Réseau Tubulure handles your insurance claim

What we do for you:

• Detect the leak using professional equipment — no damage to your property
• Write a full technical report with photos, precise location, and nature of the fault
• Help you file the insurance claim in the format your insurer requires
• Follow up with your insurer if needed

In the vast majority of cases, you pay nothing upfront.

Step by step: what to do if you suspect a leak

Step 1: The meter test

Turn off every tap and appliance. Note your water meter reading. Wait 30 minutes. Read the meter again. If the numbers have moved, you have an active leak.

Step 2: Isolate the area

Turn off your main stopcock (usually under the kitchen sink). If the meter stops, the leak is inside your apartment. If it continues, the leak is in the shared building pipes — contact your building manager (syndic) immediately.

Step 3: Call us

Describe the symptoms. We'll ask a few questions to guide the search and offer you a fast appointment, often the same day.

Frequently asked questions

Do your plumbers speak English?

Yes. Several of our technicians are fully bilingual and can conduct the entire intervention in English — from the first call to the technical report.

How long does leak detection take?

Most interventions take 1 to 2 hours depending on the configuration of your water network and the location of the leak.

What if the leak is coming from a neighbour?

We'll tell you clearly. We provide a technical report identifying the probable source, which you can use with your building manager or your insurer to initiate the inter-party claim process.
