Process of a facade project

The inspection of the facade determines the necessary treatment: simple cleaning, targeted repair, or complete resurfacing with insulation. The ambient humidity in valley areas requires particular attention to this initial diagnosis, as does the condition of the roof, often the source of infiltrations that degrade the upper part of the wall's coating.

Work begins with cleaning and preparing the surface, followed by repairing cracks and applying the coating or installing the chosen cladding. The finishing touches come last.

A standard facade project lasts one to three weeks depending on the surface area and complexity, with an additional constraint related to the weather for coatings that require precise drying times.

Which materials for your facade

Lime plaster

A traditional material that allows the wall to breathe, particularly suitable for older buildings in Clausen and Pfaffenthal where moisture management remains a constant challenge throughout the year.

Acrylic render

More waterproof and available in a wide range of shades, it is suitable for more recent constructions without specific heritage constraints, with simpler maintenance over the years.

Composite cladding

Resistant to moisture and virtually maintenance-free, it offers a durable solution for facades most exposed to the valley's elements, without the constraints of traditional plaster.

Areas of intervention in Luxembourg City

• Clausen and Pfaffenthal: facades exposed to valley moisture
• Belair and Limpertsberg: high-end facades to preserve
• Bonnevoie: renovation of old terraced houses
• Kirchberg and Gasperich: contemporary cladding on recent constructions

Regulations and subsidies in Luxembourg

Any modification to the exterior appearance of a building, including a change of color, requires municipal authorization in Luxembourg. Certain areas with marked architectural character apply even stricter aesthetic rules.

External thermal insulation work can benefit from the Klimabonus scheme and the super-reduced VAT rate of 3% for homes over ten years old, significantly reducing the net cost of a project that combines aesthetics and energy performance.

Why choose Avenir Rénovations for your facade

A successful facade depends as much on the initial diagnosis as on the execution: identifying the true cause of an infiltration before addressing it prevents having to redo the same work two years later for a poorly resolved issue the first time.

Expertise adapted to the local climate

Our teams are familiar with the specific constraints of valley neighborhoods, which are more exposed to humidity than the surrounding plateau, and adapt materials and installation techniques accordingly.

Know-how suited to local construction

Each intervention is carried out according to techniques appropriate to the existing support, with strict adherence to drying times between each applied layer, even if it slightly extends the announced timeline.

A guarantee of durability

We take responsibility for the longevity of the treatments applied, a crucial point for a component that protects the entire building for several decades.

Permits, frequency, and external insulation

A permit is required as soon as the exterior appearance is modified, including for a simple change of color; the required declaration is prepared with the municipality of Luxembourg. Expect an ideal frequency of fifteen to twenty years for a classic coating, slightly less in valley neighborhoods more exposed to humidity like Clausen or Pfaffenthal. A facade renovation is also the perfect time to insulate externally, as scaffolding and surface preparation are already necessary for the renovation alone.

Maintenance, financial aid, and the best time to intervene

Periodic cleaning and preventive anti-moss treatment significantly extend the lifespan of the finish, particularly useful in the most humid areas of the capital. When the project includes external thermal insulation, the Klimabonus and the super-reduced VAT rate of 3% generally apply, significantly reducing the net cost; however, a simple aesthetic renovation without insulation does not benefit from these provisions. Spring and summer offer the best drying conditions for coatings, a particularly important factor in valley neighborhoods where ambient humidity naturally slows this process.

Trust your facade to Avenir Rénovations Luxembourg

A well-maintained facade protects the entire building for decades. In valley neighborhoods like Clausen and Pfaffenthal, this vigilance is even more crucial against ambient humidity, to avoid more costly issues later on.

Our teams operate throughout Luxembourg City, providing a free diagnosis that precisely determines the appropriate treatment for your facade and its exposure, whether it is located in the valley bottom or on the drier heights of the capital.

The facades of Clausen and Pfaffenthal often share a common vulnerability: reduced sun exposure that slows natural drying after rain, promoting the appearance of moss and persistent moisture stains. A poorly chosen coating, too impermeable, paradoxically worsens this phenomenon by trapping moisture against the wall instead of allowing it to escape naturally to the outside over the seasons.
