Why choose Avenir Renovations?
When should you consider an exterior wall renovation in Geneva?
A wall that changes color in patches, a facade with peeling paint, a frame that is warping, these signals are unmistakable. Exterior wall renovation in Geneva is necessary when the support shows cracks that penetrate the coating, or when water seeps in with every rain. The Geneva buildings, often century-old in historic neighborhoods, require special attention to current SIA standards.
Beyond visible damage, mosses that colonize a north-facing wall betray a lasting excess of humidity, favored by the lake's fog. The age of the building also matters, as a wall built before the 1980s often provides insufficient insulation against current energy requirements. A simple facelift is not always enough to meet these demands. In this case, facade renovation is considered in parallel, to address wall and thermal envelope in a single project, rather than in two phases.
How does Avenir Rénovations manage your exterior wall renovation in Geneva?
At Avenir Rénovations, our company structures each exterior wall renovation in Geneva around a single point of contact, from the first meeting to the completion of the project. This organization avoids unpleasant administrative surprises, such as building permit applications with the municipality.
It also coordinates the various trades involved in the project, ensuring a service that meets the owner's expectations. Our renovation company also works on the roof or framework when the project requires it, but here remains focused on your exterior walls. In Geneva, these processes sometimes involve the Department of Territory, especially for buildings visible from public spaces.
What work is required for an exterior wall renovation?
Any renovation of an exterior wall in Geneva follows a rigorous method designed to last for several decades. Buildings in the historic center often feature stone or flint walls, while more recent constructions favor concrete blocks. Our building professional first assesses the nature of the substrate before engaging in the necessary masonry work for its modernization. Several trades often intervene on the same wall. Each job combines structural integrity and aesthetics, respecting the architectural character of the canton.
On a stone wall weakened by time, our renovation company prioritizes a localized underpinning. This technique consolidates the base without dismantling the entire structure. Precise work, carried out step by step, avoids any risk to neighboring structures.
The old joints, often lime-based, are replaced with a mortar compatible with the original stone to preserve its ability to breathe. This structural modernization prepares the ground before any finishing work. For Meillerie stone facades, common in old Geneva, the team adjusts the grain of the mortar to the original shade. On a listed building, our building professional also coordinates the procedures with the cantonal heritage service.
The choice of covering primarily depends on the original substrate of the wall. On a concrete block wall as well as on a stone wall, several coverings are suitable depending on the desired result. Our building professional guides you towards the most appropriate solution for your facade.
- Single-layer render for a uniform finish and good adhesion on a concrete block wall
- Lime plaster, more breathable, particularly suitable for a stone wall
- Insulating render compliant with SIA standards for thermal gain on poorly insulated facades
At Avenir Rénovations Geneva, our craftsmen then apply a water-repellent render as a finish to repel rainwater without trapping residual moisture. This step shapes the visual identity of the building for decades to come.
What budget should be planned for renovating an exterior wall in Geneva?
The budget for an exterior wall renovation in Geneva depends on several criteria. The surface to be treated, the nature of the support, and the type of finish chosen all come into play. A structurally sound wall that requires only a new coating costs much less than a damaged facade. The latter often requires a complete renovation and external thermal insulation.
The canton of Geneva also has labor rates higher than the Swiss average, a factor to consider in any serious estimate. This budget remains indicative until the Project Manager has visited the site. Several detailed quotes, including different possible coatings, allow for adjustments to the project according to your actual budget.
