Owning or buying a property around [Grasse](https://cassini-expertise.fr/grasse-secheresse-argile-fissures-donnees-officielles/) – Châteauneuf-Grasse, [Opio](https://cassini-expertise.fr/opio-secheresse-argile-fissures-donnees-officielles/), Valbonne, Le Bar-sur-Loup – comes with challenges that French buildings know well: rising damp in old stone walls, mould in renovated houses, cracks after dry summers, and disputes with local builders. Our Antibes-based practice helps English-speaking owners navigate all of this, with reports written in clear terms you can act on.

Stéphane Cassini is an independent building expert working independently for owners. He works for **you only** – not for insurers, not for builders, and he sells no products or works.

## What we do for English-speaking clients

- **Humidity & mould diagnosis** – find the true cause (condensation, rising damp, infiltration), get a written report with the correct scope of works;
- **Pre-sale / pre-purchase expert reports** – essential around here: buyers’ surveyors (experts) flag humidity and cracks, and a proper independent report protects your price;
- **Builder disputes** – defective works, unfinished projects, invoices for poor quality: we build the technical case, and if needed we support you before the **Tribunal judiciaire de Grasse**;
- **Insurance claims** – water damage, drought-related cracking (cat-nat), under-evaluated claims: we challenge the insurer’s expert with measurements, not opinions.

## Why foreign owners call us more often than you’d think

Many English-speaking owners around Grasse spend winters abroad or let their houses. Empty, badly heated houses in this climate develop condensation mould within one or two seasons – and tenants or caretakers rarely report it in time. By the time you return, walls are stained, wardrobes smell, and a buyer’s surveyor turns the whole thing into a price negotiation. We diagnose what actually happened, in writing, so you can decide with facts instead of guesses.

The second classic situation: works carried out while you were away. A roof “repaired”, a facade “treated”, a damp course injected – invoices paid from abroad, results disappointing. We build the technical file (measurements, standards, comparative quotes) that turns a vague complaint into a claim a contractor or its insurer must answer.

## Understanding the French buyer’s survey

When you sell, the buyer’s expert (diagnostiqueur or independent surveyor) flags humidity, cracks and mould in his report – and each mention becomes a negotiation lever. Sellers who anticipated with **our own report** keep control: the cause is identified, the works are costed, the file is clean. Sellers who improvised lose 5 to 15% on the price, or the buyer walks away. We prepare that file with you before the first viewing.

## Practical questions from our English-speaking clients

### Do you write reports in English?

The report itself is in French – French notaires, buyers’ experts and courts require it – but every report comes with a call (or meeting) in English where we walk you through each conclusion, and the executive summary of causes and works can be provided in English on request.

### How fast can you visit?

Within the week anywhere in the pays de Grasse – Grasse, Châteauneuf-Grasse, Opio, Valbonne, Cabris, Spéracèdes, Le Bar-sur-Loup, Tourrettes-sur-Loup. Written report within 2 to 5 days of the visit. Free quote first, no obligation.

### Can you help with insurance after storm or drought damage?

Yes – that is a large part of our work. We measure, document and challenge the insurer’s expert when damages are under-evaluated, including drought cracking recognised as natural disaster (cat-nat) in the Var and Alpes-Maritimes.
