Drone aerial thermal imaging in Blois
Drone thermography pairs a calibrated radiometric infrared camera with aerial mobility: in a single flight it reveals heat loss from a roof, insulation defects in a building envelope, failing photovoltaic panels (hot spots, blown diodes, dead strings), leaks in buried heat networks and water ingress beneath waterproofing membranes. Every pixel carries a usable temperature measurement, not just a colour.
Our thermal flights respect proper measurement conditions (indoor/outdoor temperature differential, absence of direct sun where required, humidity) and are paired with visible imagery to locate each anomaly. The report, produced in radiometric software by an operator trained in building thermography, locates and quantifies every defect. It is the reference tool for energy audits, photovoltaic plant operation and large-scale leak detection.

Rates
€500–1,800 per job — the range observed on the 2026 French market, including regulatory preparation, flight and delivery. The exact quote depends on the site, the deliverable and the airspace context in Blois.
Common use cases
- Thermal inspection of a ground-mounted or rooftop photovoltaic plant
- Heat-loss audit of a commercial building or co-owned residence
- Leak detection on a buried district-heating network
- Detecting water ingress beneath flat-roof waterproofing
- Searching for people or animals (verification flights, fawns before mowing)
- Insulation checks before/after energy renovation works
The local context in Blois
Prefecture of Loir-et-Cher, Blois terraces its old town between the Loire and its royal château, residence of seven kings and ten queens of France, famous for its François I staircase. The city lies within the UNESCO-listed Loire Valley: flights must reckon with this protected landscape, Blois-Le Breuil aerodrome (LFOQ) to the north-west, and the proximity of Chambord — whose national estate is off-limits without express authorisation. The Saint-Laurent-des-Eaux nuclear plant, 15 km upstream, imposes its prohibited zone.
The Blois economy combines château tourism, pharmaceutical and cosmetics industries, and agriculture (Sologne strawberries, Cheverny and Touraine vineyards). Typical drone missions: tourism promotion (with authorisations), real estate, construction monitoring, agricultural and vineyard imaging of the Blésois, structure inspection on the Loire.
Applicable regulations
Thermography follows the rules of the site being flown: open category A2/A3 for ground-mounted solar farms and buildings in clear areas (professional thermal drones usually exceed 900 g), specific category STS-01 with prefectural declaration for buildings in built-up areas. One specificity: building thermal flights are ideally flown at dawn or at night in winter, yet night flying is prohibited in the open category — it requires a specific-category authorisation or falls back on permitted dawn/dusk slots. Height under 120 m, AlphaTango operator registration, and particular care with parasitic reflections, which dictate controlled shooting angles.
Frequently asked questions
What time of year should building thermography be done?
From October to April, when the gap between the heated interior and the outside reaches at least 10°C. Flights take place early in the morning, before the sun warms the walls and skews the readings.
How much solar capacity can be inspected in one day?
An automated flight covers 10 to 20 MWp per day depending on the plant layout, with automatic hot-spot detection and each faulty module located by its coordinates.
Does the thermal camera measure exact temperatures?
Yes, provided a calibrated radiometric camera is used and material emissivity and ambient conditions are entered: typical accuracy is then ±2°C, sufficient for any building or photovoltaic survey.
Can this service be flown anywhere in Blois?
Almost: Zone interdite de la centrale nucléaire de Saint-Laurent-des-Eaux en amont; Aérodrome de Blois-Le Breuil (LFOQ); Domaine national de Chambord à proximité (survol soumis à autorisation). Depending on the exact location, the pilot picks the right framework (open or specific category) and files the required declarations — included in the quote.
