HallsMarble polishing
An even shine, from satin to mirror, chosen with you.
Reception halls, client lounges and grand staircases restored outside opening hours by an identified team bound by confidentiality.
Between Rue de la Corraterie, Rue du Rhône and Quai des Bergues, Geneva’s banking district lines up sober façades that often conceal entrance halls of great elegance. Veined white marble, two-tone floors, grand staircases with wrought-iron balustrades, client lounges with stone tables: these interiors speak of stability and discretion, two values close to the heart of wealth management.
Les Traitements du Sud · Geneva restores and maintains the marble of private banks, family offices, business law firms, fiduciaries and corporate headquarters. We work on reception halls, meeting lounges, grand staircases, executive washrooms and the worktops of reception areas.
In these settings, technical quality alone is not enough. It takes an organisation compatible with building security, work carried out outside opening hours, an identified and stable team, and an unreserved commitment to confidentiality. That is how we work.
Every project starts with a visit with the facility manager or head of general services, followed by a free quote in Swiss francs, detailed by area, and a schedule built around your constraints.
A private bank does not open its doors to just anyone, and rightly so. Our way of working adapts to your procedures.
The same technicians attend from one visit to the next. We send their names and identity documents in advance for accreditation, and they follow the access, badge and escort rules set by your security department.
We work in the evening, overnight, early in the morning or at weekends, as your security allows. On Monday morning, the reception hall is ready for the first appointments.
We are happy to sign a non-disclosure agreement. No photographs are taken beyond the surfaces being treated, no documents are approached, and we never name an institution in our communications.
A bank’s hall is often calmer than a hotel lobby, but it is looked at more closely. A client waits a few minutes, observes, judges. Dull marble in front of the reception desk, fan-shaped scratches by the revolving doors, darkened joints: all details at odds with the standards on display.
We restore an even surface through polishing, with a finish chosen with you: a mirror polish for a contemporary hall, a softer satin for a 19th-century building on the Corraterie. Deep scratches are first removed by wet grinding, with no dust reaching neighbouring offices.
For large areas, see also our page on marble floor restoration.
One contact on our side, one on yours: the key to a smooth job in a secure environment.
We tour the building with the facility manager, identify the marbles and note the condition of each area, staying within the zones we are authorised to access.
A free quote in Swiss francs per area, accompanied, if you wish, by a non-disclosure agreement signed before work begins.
Named team list sent to security, out-of-hours slots approved, access and lock-up procedure agreed.
Wet methods, furniture protected, nothing moved without permission. Each area is handed back clean and dry at the end of the slot.
Suitable protection, inspection with your contact and a written report of the work carried out.

In meeting lounges, marble is within arm’s reach: coffee tables, consoles, decorative fireplaces, window sills. Coffee cups, glasses of sparkling water and slices of lemon left on the stone leave rings and acid etching, which we remove by stain removal and local re-polishing, without taking the furniture out of the room.
The grand staircase of a historic headquarters is often the building’s centrepiece. Treads worn in the middle, chipped nosings, dulled risers: we restore them through repair and polishing, step by step. Our marble staircase page explains this work in detail.
A marble lounge fireplace is treated in the same way; see our marble fireplace page.
Geneva’s financial centre mixes 19th-century buildings, often listed or inventoried, with recent headquarters featuring large expanses of polished stone. The former call for respectful restoration: keeping the patina, choosing a satin finish in keeping with the period, repairing rather than replacing. The latter expect a perfectly even polish on large-format slabs, where the slightest flaw shows under the raking light of glazed façades.
In both cases, Geneva winters leave their mark: de-icing salt and grit carried in from the pavements of Rue du Rhône dull the first few metres of the hall. A spring maintenance visit erases these marks and prepares the stone for the year ahead.

ContractsScheduled visits outside opening hours.
Yes, that is our standard arrangement for financial institutions. We work in the evening after closing, overnight, early in the morning or at weekends, within the slots authorised by your security. Areas are handed back clean, dry and ready to receive clients before the next opening, with no trace of our visit.
Yes. For each client we put together a stable team, whose names and identity documents we send to your security department for accreditation. In the exceptional event of a replacement, we let you know in advance. Your security staff therefore always know who is in the building.
Gladly. We sign your institution’s non-disclosure agreement before any work begins. In practice, our teams go nowhere near documents or workstations, photograph only the surfaces being treated, and we never name a client in our communications or references.
Our wet methods produce no fine dust likely to trigger detectors. Before the job, we agree with your security on the open areas, the hours and the access and lock-up procedure. A guard can accompany us if your rules require it; we simply adjust our schedule.
Yes. Glass rings, acid etching and light scratches on a table, console or fireplace surround are treated on site with compact equipment. The surrounding floor and furniture are protected, and the room is handed back clean within the planned slot.
For a 19th-century building, a satin or soft polish often respects the spirit of the place better than a high-gloss mirror. We carry out a test on an inconspicuous area so you can judge for yourself before approving. The decision is yours, in liaison with your architect if the building is subject to heritage protection.
We work for financial institutions and prestige offices throughout the city and in the municipalities below. To arrange a visit, use our contact page.
