Leak Detection in Paris: Costs, Insurance Reimbursement and Full Procedure

When someone tells you that you have a leak, the first question is almost always: 'How much is this going to cost?'
That's completely reasonable. And the answer will probably surprise you.
In the vast majority of cases, leak detection in Paris costs you nothing. Not because it's free. Because it's reimbursed 100% by your home insurance — and because Réseau Tubulure handles the paperwork for you.
Here's everything you need to know about pricing, insurance coverage, and how the process works.
What leak detection costs in Paris — market rates
Prices for leak search and detection in Paris vary depending on the method used, the complexity of the search, and which plumber you call.
Indicative price ranges:
- Acoustic detection (basic): €150 to €350 depending on the duration and network configuration
- Infrared thermal imaging: €200 to €450, often combined with acoustic detection
- Tracer gas: €300 to €600 for complex cases — thick slabs, buried pipes
- Technical report + photos: often included in the package, but worth confirming
These figures look significant. That's exactly why the insurance reimbursement question is so important.
The key point: in most cases, you pay nothing
Your French home insurance contract (assurance habitation) almost certainly includes a guarantee called garantie dégâts des eaux — water damage cover. This guarantee covers not only the damage caused by a leak, but also the costs incurred to find its source.
What this guarantee typically covers:
- Leak detection costs (plumber, equipment, technical report)
- Reinstatement work after the search (replastering, repainting if necessary)
- In many contracts: the water damage itself
The essential condition: the work must be carried out by a qualified professional, and a written technical report must be provided. That's exactly what Réseau Tubulure delivers as standard.
Why Réseau Tubulure can guarantee 100% coverage
Réseau Tubulure has developed direct agreements with the main insurance companies operating in Paris and the inner suburbs. We know each insurer's procedures, the required forms, and the deadlines to meet.
What we handle for you:
- Writing the technical detection report (photos, precise location, nature of the fault)
- Compiling the insurance claim file
- Submitting the file to your insurer in their required format
- Following up with the insurer if needed
In the vast majority of cases, you pay nothing upfront.
The full procedure, step by step
Step 1: You call us
Describe the problem — damp patch, spinning meter, unusually high bill. We ask a few questions to guide the search and offer you an appointment quickly, often the same day. If you're unsure about your coverage, tell us at this stage. We can check with you before coming out.
Step 2: Detection
A Réseau Tubulure technician comes to your address. They use the right equipment (acoustic detection, thermal camera or tracer gas) and locate the source of the leak precisely — without unnecessary damage.
Step 3: Technical report
You receive a complete report: before/after photos, precise location of the leak, nature of the fault, repair recommendations. This document is written in the format expected by insurers.
Step 4: Insurance claim
We compile the claim file and help you submit it to your insurer. In some cases, we submit it directly.
Step 5: Reimbursement
Your insurer validates the coverage based on the report. Intervention costs are reimbursed. In most cases, you pay nothing.
What if the leak is coming from a neighbour or shared pipes?
If the leak doesn't originate from your apartment, we'll tell you clearly. We provide a technical report identifying the probable source, which you can use with your building manager (syndic) or to trigger the inter-insurer process.
