English-speaking building expert on the Côte d’Azur – Cannes, Mandelieu, Mougins, Antibes
If you are an English-speaking property owner on the Côte d’Azur facing a building dispute, poor workmanship, or defects in a renovation or new build, Cassini Expertise provides independent technical assessments – with all inspection, advice and reporting delivered in English.
Based in Antibes, our expert covers the full Alpes-Maritimes (06), Var (83) and Bouches-du-Rhône (13): Cannes, Mandelieu-la-Napoule, Mougins, Le Cannet, Grasse, Antibes, Nice, Saint-Raphaël, Fréjus and beyond.
Why international owners call Cassini Expertise
You get an independent opinion, not a sales pitch. We sell no repairs, no materials, no services beyond our expertise. The contractor wants to close the file; your insurer wants to limit the claim; we document what is actually there – with dated measurements, professional instruments and photos.
You get a report in English, usable in France. Every report can be written in English, French, or both. It is structured to be handed to your avocat, your insurer, your syndic, or used in an amicable or judicial procedure in France.
You get 15 years of construction experience. Before becoming an expert surveyor, our expert spent 15 years in public works and site management. He knows how buildings are put together, how defects appear, and what contractors sometimes try to hide.
Typical situations we handle for British and international owners
- Ongoing renovation disputes – documenting poor workmanship and DTU non-conformities before final handover, so you are not locked into implied acceptance
- Pre-purchase inspections – independent assessment before you sign a compromis de vente on a French property
- VEFA defects and réserves – new-build defects identified and formally documented at delivery
- Cracks, damp, subsidence – diagnosis with professional instruments, root-cause analysis
- Insurance disputes – independent second-opinion expert assessment when the insurer’s assessment falls short
- Contractor disputes and mise en demeure support – technical evidence to back your legal position
How it works
Step 1 – Free phone consultation (15 minutes, in English). You describe the situation; we tell you honestly whether an expert visit is worth it.
Step 2 – Site inspection (typically 2-3 hours). Full technical assessment with professional instruments: crack gauges, moisture meters, thermal camera. Every finding dated and photographed.
Step 3 – Written report delivered within 2 to 5 days. Structured, referenced to French building standards (DTU), with a clear hierarchy of defects and recommended actions.
