🏢 FACADE INSPECTION · THIONVILLE (57) · €300–1,200 PER JOB
Drone facade inspection in Thionville
Drone facade inspection documents a building's condition over its full height without a lift platform, rope-access technicians or road closures. Cracks, concrete spalling, loose elements, rebar corrosion, render detachment, tired expansion joints, water ingress: the high-resolution sensor, combined with zoom, records millimetre-scale defects tens of metres up. It is the ideal tool for pre-renovation surveys and the statutory monitoring of high-rise buildings.
The standard deliverable is a report organised by elevation (north, south, east, west) with defects mapped onto rectified photos, supplemented if needed by a georeferenced facade orthophoto usable by your engineering office. Property managers, architects, inspection bodies and local authorities use our surveys to prioritise works and secure perimeters where falling material is a risk.

The local context in Thionville
Moselle's second city, Thionville lives to the rhythm of neighbouring Luxembourg: tens of thousands of cross-border workers transit daily via the A31 and the station. The belfry, the Tour aux Puces and the Moselle quays form the historic core, while the Uckange blast furnace (the listed U4) and the Fensch valley's steel heritage tell the iron saga. Two major airspace constraints: the prohibited zone of the Cattenom nuclear power plant, less than 10 km north-east, and the Luxembourg border — flying on the grand-ducal side means switching to Luxembourg's drone regulations.
The local economy combines cross-border services, multimodal logistics (Thionville-Illange port, Europort), residual steelmaking and brownfield regeneration. Drone missions: monitoring of logistics and housing projects in a border-pressured property market, structure inspection on the Moselle, industrial heritage, thermography.
Applicable regulations
Facades to inspect are almost always in built-up areas: the usual regulatory framework is the specific category (STS-01 scenario, populated-area flight with a class C5 drone) with prior prefectural declaration, the open category over public space (open to professionals since 1 January 2026, no overflight of people, daytime only), or sub-category A1 with a sub-250 g C0 drone for small buildings. The flight is conducted a few metres from the wall, well under the 120 m limit; a ground safety perimeter is marked out when the drone operates above public space, and neighbouring owners' consent is sought when the flight requires crossing their plot. Operator registered on AlphaTango, professional aerial liability insurance and Géoportail drone-map checks are systematic.
Frequently asked questions
Does the drone fully replace an engineering survey?
No: the drone provides the exhaustive, documented visual record; structural interpretation of defects remains the engineer's or architect's job. Our reports are designed to feed directly into their analysis.
Can you inspect a facade on a busy street?
Yes, with a specific-category flight declared to the préfecture and a ground safety perimeter managed by an assistant. We often work early in the morning to minimise disturbance to pedestrians.
How accurate is the photographic survey?
At 5 m from the facade, resolution reaches roughly 1 mm per pixel: microcracks, joint defects and early corrosion are clearly identifiable and measurable on the images.
Can this service be flown anywhere in Thionville?
Almost: Zone interdite de la centrale nucléaire de Cattenom; Frontière luxembourgeoise (réglementation drone différente); Emprises portuaires et logistiques d'Illange. Depending on the exact location, the pilot picks the right framework (open or specific category) and files the required declarations — included in the quote.
