A staircase is at once a means of getting around, a safety feature and, often, a decorative one. Whether it is an interior wooden staircase, a concrete flight, a metal model or an outdoor access, the work calls for precise measurements and good coordination between several trades.

What staircase work covers in French-speaking Switzerland
The word “staircase” covers very different projects. The most common are:
- Building a staircase in a house under construction, for access to the attic, a mezzanine or a converted basement.
- Complete replacement of a worn-out, noisy staircase that no longer suits how the home is used.
- Renovation: sanding and varnishing wooden steps, changing the covering, replacing damaged risers.
- Balustrades and handrails: replacement, bringing up to standard, adding a second handrail.
- Outdoor staircase: steps up to an entrance, a front stoop, a garden or patio staircase, exposed to frost and damp.
- Staircase in a co-owned building: the stairwell of an apartment block, with shared coverings, lighting and safety features.
The usual materials are wood, metal, concrete, natural or reconstituted stone, glass for some balustrades, and combinations of these. Each has its own installation requirements, upkeep and durability.
When to call a professional for your staircase
Some minor finishing work can be done yourself, but a staircase affects people’s safety: a poorly fixed step or a balustrade that is too weak can cause a serious fall. A professional is advisable in the following situations:
- the steps creak, move or show cracks;
- the load-bearing structure, the stringer or the slab seem affected by damp or corrosion;
- you want to change the shape (straight, quarter-turn, spiral) or the position of the staircase;
- an opening has to be cut in a floor;
- an elderly person, a young child or a person with reduced mobility needs to be able to use it safely;
- the staircase is in an old or listed building, where the original appearance matters.
A tradesperson takes the dimensions on site, assesses the condition of the structure and tells you what is feasible. This visit avoids ordering mistakes, which are common when you measure yourself.
Trades, training and standards: what is different in Switzerland
Several professions work on a staircase. The carpenter makes and fits wooden structures; the structural metalworker works steel, stainless steel or aluminium; the mason pours or repairs concrete structures; the tiler and the floor fitter finish the steps; the painter or varnisher treats the surfaces. In Switzerland, most of these trades are learned through an apprenticeship leading to a Federal Certificate of Proficiency (CFC), which shapes basic training. This is not a guarantee of quality for a particular job: it is the quote, the references you ask for and your discussion with the company that let you form an opinion.
Safety requirements (balustrade height, step dimensions, lighting) are set by building rules and by the regulations applicable to each building. They may differ depending on whether it is a single home, a multi-unit building or a space open to the public. Ask the company which requirements it relies on, and check with the municipality or the relevant cantonal department if in doubt.
Permits and energy: staircases in Geneva, Vaud, Valais, Fribourg, Neuchâtel, Jura and Bern
A simple replacement of steps does not generally require a permit, but a structural alteration, a new outdoor staircase or work on the facade may. Each canton has its own procedure:
- Geneva: building permits are issued by the canton, through the Office des autorisations de construire (building permits office). The old town and protected districts add constraints, and many rental buildings are managed by property managers whose consent is required.
- Vaud: the permit is issued by the municipality; the file goes through the cantonal permits centre (CAMAC) when State departments need to give an opinion. The old towns and the Lavaux vineyards, a World Heritage site, call for particular attention.
- Valais: the permit is issued by the municipality in building zones and by a cantonal commission outside building zones. For chalets and second homes, the federal law on second homes applies in the municipalities concerned.
- Fribourg: applications are submitted through the cantonal platform FRIAC; the permit is issued by the prefecture or the municipality depending on the type of work. The canton is bilingual and its old towns are protected.
- Neuchâtel: applications go through the cantonal counter SATAC, with the decision taken by the municipality. The watchmaking heritage of La Chaux-de-Fonds and Le Locle, a UNESCO site, may affect work in the buildings concerned.
- Jura: the permit is issued by the municipality or by the canton depending on the scale of the project. The old towns of Delémont, Porrentruy and Saint-Ursanne need to be taken into account.
- Bern (Biel/Bienne): the permit is issued by the municipality or the prefecture depending on the project. Biel/Bienne is officially bilingual, French and German.
On the energy side, a staircase alone is rarely affected, but a larger project (insulating a stairwell, replacing windows, a full renovation) may fall under cantonal energy legislation: the cantonal energy law (LEn) and the cantonal energy office (OCEN) in Geneva, which runs the Buildings Programme, or cantonal energy departments elsewhere, each with its own subsidy programmes. Conditions change; check with the relevant cantonal department before signing.
Preparing your quote request for a staircase
The clearer your description, the more precisely companies can respond. State:
- the type of building (house, flat, apartment block) and your status: owner, tenant with the landlord’s consent, co-owner or business;
- the location of the staircase (interior, exterior, shared stairwell) and the number of floors it serves;
- the current condition and what you want: repair, renovate or replace;
- the materials or style you have in mind, even if you are still undecided;
- site access constraints: narrow passage, no lift, the only staircase in the home;
- the period you would like the work to take place;
- photos and, if possible, a few approximate measurements.
Also mention whether the staircase is the only access to part of the home: this affects how the work is organised.
What a reliable staircase quote details
A good quote is read line by line. In principle it specifies:
- the description of the work: type, shape, dimensions, materials and finishes;
- the removal and disposal of the old staircase, or its partial retention;
- supply and installation, with the two distinguished;
- related elements: balustrade, handrail, lighting, protection of walls and floors;
- preparatory or restoration work (masonry repairs, painting, floors);
- the services that are excluded and the points that could lead to an extra charge;
- the payment terms and the validity of the offer.
Compare quotes on the same basis: two amounts are comparable only if the services described are too.
What makes the cost of a staircase vary
No reliable amount can be given without seeing the premises. The cost depends in particular on:
- the material chosen and its quality;
- the shape: a straight staircase is not as complex as a winder or spiral one;
- whether it is made to measure or uses standard components;
- the height to be covered and the number of steps;
- access and handling difficulties;
- the extent of related work (opening in the floor, reworking floors, painting);
- the safety and finishing elements;
- the time of year and the availability of companies.
Only a quote drawn up after examining your situation will give you a reliable figure.
Legal warranties on staircase work
The Code of Obligations (CO) governs defects in work carried out. For work on immovable property, art. 371 CO provides a five-year period to claim for defects; for movable property, the period is two years. A staircase firmly fixed to the building generally falls into the first category, but the classification depends on the specific case. If your contract refers to the SIA 118 standard, its provisions apply in addition: read the contract before signing. In all cases, report a defect as soon as you notice it and keep a written record.
