Villefranche's vaulted ground floors
Old stores and vaulted cellars turned into living rooms. A stone vault, one wall facing outside, no through ventilation: condensation settles on the stone and black patches follow the curve of the vault.
Villefranche-sur-Mer, Beaulieu-sur-Mer
Two neighbouring communes and two opposite kinds of building: in Villefranche, an extremely dense old town running down to the bay, with vaulted ground floors and covered streets; in Beaulieu, villas and belle-époque blocks around the harbour, with basements and gardens.
We remove black mould from walls and ceilings, treat bathroom joints and cellars, without breaking anything and without a building site. The quotation is made from photos, before we travel out.

The local building stock explains most cases. Here is what comes up again and again.

Old Villefranche is built on top of itself, with covered passages and homes that never see the sun. Party walls stay cold, and mould returns every winter in the same place.
Laundry rooms, plant rooms, wine cellars, gardens that hold water. Moisture produced below rises through the house, and patches sometimes surface a floor above where they started.
Constant salt air, windows shut in winter, residences partly used in season only. Mould starts on window reveals, in north-facing corners and on the bathroom ceiling.
Example of a treated surface: visible mold is cleaned, the area is sanitized and prepared to stay clean.
Before
AfterTreatment of affected surfaces with suitable products, 3-month guarantee. First pass €25 per m² of surface actually treated — not the floor area of the room, but the area we really work on — and every further pass cheaper than the one before. Visible mould needs 3 to 5 passes, an old infestation 5 to 15. Clean surfaces in the same room are treated preventively from €15/m². We clean visible mold without breaking walls, painting or heavy renovation. Rates and worked examples
Minimum call-out in this town: €200 (zone B), travel included.
Cause diagnosis and room climate survey — surface temperature readings, humidity, dew point, ventilation, with a written report. A separate service, €150 in zone A and €200 in zone B, credited against treatment ordered within 30 days. What the report contains
We also treat cellars and outdoor surfaces — facades, plinths, terraces — from the ground, up to 4 m, on an individual quotation.
After treatment we can also provide simple cleaning of the room. Cleaning is available at €25 per hour, minimum 3 hours, excluding construction waste.
We cover the whole area.
Villefranche-sur-Mer and Beaulieu-sur-Mer are in zone B: the minimum call-out is €200, travel included. If you have several rooms to treat, it is worth grouping everything into a single visit.
Yes, and it is a common case in Villefranche. Stone and vaulting are no problem for the product. What does matter is that the developed surface of a vault is larger than it looks: we measure it from photos and give you the figure we will use before the work.
That is the rule in old Villefranche. Where equipment and water have to be carried by hand, the access surcharge from €40 applies, quoted in advance from the address.
€200, zone B, travel included. The same as Nice, Cagnes and Antibes.
The service area is intentionally focused so we can stay realistic and responsive.
