The Gironde is one of the best-equipped departments in France for private swimming pools. The Gironde climate: intense summer heat, significant temperature variation, sandy soils around the Bassin d'Arcachon and the Médoc, subject pools to particularly harsh conditions. The result is frequent, often silent, and always costly leaks if ignored.
Faced with abnormal water loss, the temptation to call the first pool professional you find is high. Bad idea: searching for a pool leak requires specific equipment: tracer gas, an endoscope camera, acoustic listening devices, fluorescein, and a precise reading of buried hydraulic networks. A failed diagnosis means unnecessary work, or worse, a leak that continues to silently worsen.
Our editorial team has reviewed the main specialist companies active in the department. Here is our 2026 ranking, with ADN at the top, an expert in non-destructive swimming pool leak detection in Gironde for over 14 years.

When the pool level drops and there's no explanation, DNA is the name that Bordeaux owners have learned to remember. Based in Mérignac, the company has been specialising in all types of tiled concrete pools, polyester shells, and liners for over 14 years, without emptying the pool or prior demolition.
What sets ADN apart in the local landscape is, first and foremost, the composition of its teams. Its technicians are qualified plumbers, trained in-house and loyal to the company for several years. A rare continuity in the sector, which translates into an understanding of hydraulic networks that generalists simply don't have. Before connecting any appliance, they understand how the network is constructed, which makes all the difference to the accuracy of the diagnosis.
The methods used are non-destructive: fluorescent dye, tracer gas, endoscopic camera, acoustic listening. Each intervention concludes with a detailed technical report, recognised by all insurance companies, a document that many owners underestimate until the moment their insurer needs it.
ADN operates throughout Gironde from two agencies (Mérignac and La Teste-de-Buch), which allows for short intervention times in both Bordeaux Métropole and the Arcachon Basin. The company works for both private individuals and pool installers who prefer to outsource the detection phase to go straight to the repair.
What the editorial team liked: Impartial diagnostic positioning. DNA does not carry out repairs, so there is no point in increasing the estimate. The technical report is produced in the client's interest, not the company's.
Located in La Teste-de-Buch, Detect Bassin Operating in a territory it knows better than anyone for over 15 years: the Arcachon Basin and, by extension, the whole of Gironde. The sandy and unstable soils of this area create ground movements that put atypical stress on buried hydraulic networks – a particularity that this company has learned to deal with on a daily basis.
Detect Bassin's technicians handle all types of liners — liner, shell, tiling — and cover buried pipes, infiltration zones, dampness and the technical room. The interventions are non-destructive, and the services are aimed at both individuals and professionals.
What the editorial team liked: On-site expertise rooted in a challenging region, with a real specialisation in swimming pools exposed to the constraints of the Girondin coastline.
📍 La Teste-de-Buch (33260)
O'Detect It is based in Sainte-Eulalie and covers the right bank of the Gironde — Cenon, Libourne, Saint-André-de-Cubzac — as well as Bordeaux and a large part of the department. The company focuses exclusively on non-destructive detection, with a complete technical arsenal: tracer gas, dye, endoscopic camera, acoustic listening and pressure tests.
The intervention report provided after each diagnosis is recognised by insurers, which facilitates the coverage of research costs when the contract provides for it. O’Detect works for both individuals and condominium associations.
What the editorial team liked: Documentary rigour and geographic coverage that embraces the right bank, often overlooked by Bordeaux actors.
📍 Sainte-Eulalie (33560)

The starting price for a swimming pool leak detection is published online, which avoids any unpleasant surprises.
The company is available 7 days a week and covers almost the entirety of Gironde, from Bordeaux to Libourne, including Pessac, La Teste-de-Buch and Gradignan. The techniques used include thermography, acoustic correlation and tracer gas detection.
What the editorial team liked: Price transparency – rare in this sector – and weekend availability for seasonal emergencies.
📍 Bordeaux Métropole (33)
SABACA New Aquitaine is the regional antenna of a national network specialising in non-destructive leak detection. The company operates in Bègles, Mérignac, Arcachon, Libourne and throughout Gironde, with a stated availability 7 days a week for emergencies.

What the editorial team liked: Networked organisation ensures service continuity and standardised protocols that reassure insurers and managing agents.
📍 Bègles (33130)
Wi Bord'eau operates throughout Gironde and a part of Nouvelle-Aquitaine. The company covers private basins as well as municipal swimming pools, local authorities, and insurance experts. Its technical equipment includes a drone (for roofs), a smoke machine, fluorescein, and an endoscopic camera.
For swimming pools, Wi Bord’eau carries out leak tests on seals, nozzle fittings and pipework, with a full video inspection.
What the editorial team liked: Multi-client addressing — a pool installer or a town hall can use it just as easily as an individual — and the extensive coverage towards the Médoc and the Bassin.
📍 Bordeaux and Gironde (33)
ARTIST It is distinguished by a triple expertise: leak detection on swimming pools, on pipes, and thermal detection. The company has a network of partners for repairs, which allows it to offer a comprehensive service – from diagnosis to the renovation site.
She operates in Bordeaux and throughout Gironde, with insurance compliance displayed for her pool services.
What the editorial team liked: The ability to avoid increasing the number of intermediaries between detection and repair, thanks to the integrated partner network.
📍 Bordeaux (33)

For swimming pools, services include pressure testing, video inspection, and assistance with insurance claims.
What the editorial team liked: The advertised delivery time of under 24 hours is particularly useful during the peak summer season when every lost day counts.

What the editorial team liked: A single point of contact who understands the swimming pool as a whole — ideal when a leak is related to faulty equipment rather than pipework.
