What DIAGNOFUITE does

DIAGNOFUITE is a privately held French professional services firm headquartered in St Étienne du Rouvray, within the Rouen metropolitan area, that specializes in non-destructive leak detection and diagnostic services for water networks and building envelopes. The firm deploys a comprehensive suite of electronic and electro-acoustic instrumentation, including tracer gas (hydrogen-nitrogen) injection systems, infrared thermography cameras, ultrasonic flow meters, video inspection cameras (including micro-cameras for small-diameter conduits), electromagnetic pipe and cable detectors, fiber optic probes for plastic pipes, radar material scanners, humidity meters, and smoke generators, to locate water leaks, air infiltrations, and thermal losses in buried or embedded pipes, flat roofs, and building envelopes without causing structural damage. Its service portfolio spans four lines: canalization leak detection, terrace roof leak detection, network mapping and tracing, and pressurized water network diagnostics.

The company serves property owners and managers in the residential and commercial real estate sector, industrial and commercial enterprises with complex pipe networks, public sector entities (Collectivités), and insurance companies, operating across a service radius exceeding 100 km from Rouen covering Seine-Maritime, Eure, Calvados, Yvelines, and Oise. Revenue is generated on a quote-based, per-engagement professional services basis with direct customer contact via phone, email, and the company website; services are frequently reimbursable under Multirisques Habitations (Multi-risk Home) and Dommages Ouvrages (Works Damage) insurance policies, creating a third-party payer dynamic. The firm is supported by the Haute-Normandie Region, is anchored at the Pépini ère Seine Créapolis business incubator, and holds the registered 'diagnofuite®' trademark. The company is small (1–10 employees), has operated for over 20 years, and does not disclose revenue, funding, or institutional ownership; no M&A, leadership, or expansion signals beyond the five-department regional footprint are present in the source data.

Core offering

DIAGNOFUITE provides non-destructive leak detection and diagnostic services for water networks and building envelopes in Normandy, France. The company deploys specialized electronic and electro-acoustic instrumentation — tracer gas systems, infrared cameras, ultrasonic flow meters, video inspection cameras, electromagnetic detectors, radar scanners, humidity meters, and smoke generators — to locate water leaks, air infiltrations, and thermal losses in buried or embedded pipes, roof terraces, and building envelopes without damaging structures.

Product overview

DIAGNOFUITE is a non-destructive leak detection company based in Rouen, Seine-Maritime, offering specialized services for water leak detection, air infiltration, and thermal loss detection. The company operates across Normandy and surrounding regions serving residential, industrial, commercial, and institutional clients. Their service portfolio includes four main service lines: canalization leak detection (using electro-acoustic, tracer gas, infrared thermography, and video inspection), terrace roof leak detection (using electro-acoustic, smoke, moisture meters, and thermography), network mapping and tracing (using magnetic detectors, fiber optic probes, and material scanners), and pressurized water network diagnosis (using portable ultrasonic flow meters and data loggers). These techniques are applied to buried/embedded pipes, terrace roofs, and building envelopes without causing damage to structures.

Broad incumbents

• ENGIE Solutions: French energy and building-services arm of ENGIE offering building-envelope diagnostics, thermal-loss assessment and facility-leak services to commercial and public-sector clients. Overlaps with DIAGNOFUITE's roof-terrace and thermal-loss detection lines.
• Mueller Water Products: US-listed water infrastructure provider offering leak detection, pipe-locating equipment and metering technology to utilities. Comparable on the leak-detection equipment and field-services axis though primarily US-market focused.
• Itron: Smart water metering and analytics provider whose AMI and leak-detection modules address NRW reduction for utilities. Adjacent to DIAGNOFUITE on the demand-creation side (data-driven leak alerts) but with a hardware/software business model.
• Suez Water: Major water services operator with leakage detection, network mapping and pipe diagnostics capabilities integrated into municipal contracts. Comparable on water-network diagnostic scope but with infrastructure and capital DIAGNOFUITE does not have.
• Xylem: Global water-technology company owning the Sensus and Pure Technologies brands, providing smart metering, acoustic leak detection and pipe-condition assessment. Overlaps with DIAGNOFUITE's acoustic, flow-meter and pipe-inspection methods at utility scale.
• Veolia Water Technologies: Global water and wastewater utility operator offering network diagnostics, NRW reduction and leak management services at municipal and industrial scale. Overlaps with DIAGNOFUITE in pressurized-water network diagnostics and leak localization, but operates at vastly larger scale across a global portfolio.
• Saur: French water-services operator providing network operation, diagnostics and NRW reduction to municipalities and industries. Direct overlap with DIAGNOFUITE on French water-network diagnostic services, but with utility-contract scale.

Direct peers

• Gutermann: Swiss-headquartered specialist in water-leak detection equipment and services, with acoustic and correlation-based solutions closely matching DIAGNOFUITE's electro-acoustic and network-diagnostic capabilities. Most direct product-and-service comparable in the European mid-market.

Emerging players

• Pure Technologies (Xylem brand): Specialist in pipe-condition assessment, inline inspection and acoustic leak detection for water mains, now operating under Xylem. Comparable to DIAGNOFUITE's leak-localization and pipe-inspection capabilities but focused on large-diameter trunk-main infrastructure.
• RADCOM Technologies: UK-based specialist in leak detection equipment and acoustic correlation technology used by utilities and service contractors. Comparable technology stack to DIAGNOFUITE's electro-acoustic and survey-based services, primarily a UK/regional player.
