Principality of Monaco
In Monaco mould rarely comes from a leak: it comes from the air. Very dense buildings, sealed windows that almost never open, air conditioning running much of the year, buried levels under every block. Moisture produced indoors has nowhere to go.
We treat the affected surfaces — walls, ceilings, bathroom joints, grilles and the area around diffusers, cellars — without breaking anything and without a building site. The quotation is made from photos and can be issued in writing, line by line, for a managing agent or an owner.
The local building stock explains most cases. Here is what comes up again and again.
This is the case most specific to Monaco. Cold air runs through ducts, condensation forms inside, and mould comes out on the grilles and on the ceiling all around them. We treat the accessible part without dismantling; the inside of the ducts is a job for a specialist contractor.
Airtight joinery, windows rarely opened, permanent air conditioning. The air is not renewed: mould starts in bathroom corners and dressing rooms, then behind fitted furniture.
Every building has its lower levels. Walls against the ground, weak or absent ventilation, pipework beading with condensation: the cellar becomes the starting point, and the smell rises into the common parts.
Scheduled access, fixed time slots, a condition report to document. We supply before-and-after photographs and a detailed quotation, in a form that can be attached to an owner's report or an insurance file.
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: €150 (zone A), 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.
Monaco is in zone A: the minimum call-out is €150, travel included. Paperwork is issued by Tatiana Subbotina EI, SIRET 845 294 883 00028, VAT not applicable under art. 293 B du CGI.
That is a sign that outbreaks remain inside the ducts, where we cannot reach without dismantling. The test is simple: if it reappears between two weeks and three months of actual running time, the ducts have to be opened and cleaned, which is a separate job.
Yes. Written quotation with a line-by-line calculation, before-and-after photographs, work scheduled in an agreed slot. That is the format we use most often in the Principality.
No. The product attacks neither plaster nor paint and does not require opening up the surface. What it does not do is restore the finish: if a watermark remains after treatment, repainting is a decorator's job.
The service area is intentionally focused so we can stay realistic and responsive.
