Haut-de-Cagnes
A stone village clinging to the hill, sloping lanes, vaulted passages, terraced houses with no open facade. Walls never dry and black patches return every winter in the corners and along the bottom of partitions.
Haut-de-Cagnes, Cros-de-Cagnes, centre
Cagnes sits on three very different levels: the perched medieval village of Haut-de-Cagnes, the lower town around the centre and the Cagne river, and the old fishing village of Cros-de-Cagnes on the shore. Each produces its own kind of mould.
We remove black mould from walls and ceilings, treat shower joints, cellars and garages, 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.
A stone village clinging to the hill, sloping lanes, vaulted passages, terraced houses with no open facade. Walls never dry and black patches return every winter in the corners and along the bottom of partitions.
Flat ground, a fairly high water table, 1970s and 1980s blocks. Sharp cold bridges at the slab edges, garages and cellars below ground taking up salt efflorescence.
An old fishing village right on the shore: constant spray, small old houses, flats facing one way only. Condensation settles on window reveals and in north-facing corners.
Many homes are let part of the year and shut for the rest. Shutters closed for months, no airing at all: on reopening, the bathroom and the backs of furniture are affected.
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.
Cagnes-sur-Mer is in zone B: the minimum call-out is €200, travel included. If you have several rooms or several properties, grouping everything into one visit costs less.
Not to the door, usually. Sloping lanes and vaulted passages: where equipment and water have to be carried by hand, the access surcharge from €40 applies, quoted in advance from the address.
That is common here. The quotation is made from photos sent by the tenant or the agency, access is arranged with them, and you receive before-and-after photographs with the line-by-line calculation.
It is not harmless. Spores circulate in the air and affect children, asthmatics and allergy sufferers first. In a child's bedroom we treat the visible surface and then give the whole room a preventive pass if humidity is high.
The service area is intentionally focused so we can stay realistic and responsive.
