How does a ventilation (vmc) project work in Onex?
Analysing your needs
Contact SOS-Travaux.ch and describe your ventilation (vmc) project in Onex: the more detail you provide, the faster and more accurate the match will be. We identify the best-placed professional in our network — by speciality, location and availability — from among the tradespeople active in the canton of Genève.
On-site visit and diagnosis
The ventilation (vmc) tradesperson visits Onex for a free initial assessment. They evaluate the existing condition, identify hidden constraints (concealed pipework, structural condition, moisture) and check applicable regulatory requirements. This step prevents unwelcome surprises during the works and produces a realistic, well-founded quote.
Detailed proposal and schedule
You receive a complete commercial proposal: technical description of the works, list of materials with brand names and references where relevant, a week-by-week schedule and the total budget in CHF. The price is firm and final, subject only to unforeseen issues documented in writing. You have all the time you need to compare and ask questions before signing.
Professional execution with daily updates
Works begin on the agreed date. The tradesperson complies with the Swiss standards specific to their trade — electricians must hold an ESTI authorisation, plumbers must be SSIGE-approved — and coordinates any other trades needed. You are offered regular progress updates to keep you informed at each stage of the works.
Quality check and resolution of snags
Before final handover, the tradesperson carries out their own internal quality inspection. At the handover in Onex, you note any outstanding items on a snagging list: the tradesperson commits contractually to resolving them within an agreed timeframe. Only after your sign-off does the final payment become due.

Budget and financing — Ventilation (VMC) in Onex
The budget for a ventilation (vmc) project in Onex depends on the area involved, the quality of finish selected and any technical constraints specific to your building. As a guide, prices in the canton of Genève range from 3540 to 9440 CHF/fixed price for a standard service including labour and materials. Budget an additional 10–15% reserve for unforeseen items, which are common in older buildings. On the financing side, Swiss homeowners have several levers: maintenance costs are deductible from income tax, energy efficiency investments qualify for Building Programme subsidies (potentially several thousand CHF depending on the canton of Genève), and major works can be financed through a supplementary mortgage or an early withdrawal from the third pillar. Compare these options with your bank advisor to find the most advantageous arrangement for your project in Onex.
Regulations and standards — Ventilation (VMC) in the canton of Genève
Undertaking ventilation (vmc) work in Onex without understanding the regulatory framework risks leaving you with a non-compliant installation that your building insurance may refuse to cover in the event of a claim. Swiss construction law operates on two levels: federal legislation sets out the general principles, while the canton of Genève has its own implementing regulations. In practice, these cover fire protection (AEAI requirements, mandatory for any building permit), electrical installations (NIBT standard and ESTI inspection after works), sanitary connections (SSIGE approval and compliance with municipal requirements in Onex) and thermal insulation (verified by the cantonal energy office for subsidised projects). A qualified tradesperson in the canton of Genève knows and automatically complies with these requirements — but it is useful for you to be aware of them too, to confirm that the works are being carried out correctly.
