A façade is renovated on average every 10 to 15 years — and when properly prepared, the work protects your home for the long term while adding value. Price per m², administrative procedures, reduced VAT and a tip for unlocking a grant: here is the complete guide to façade renovation in Luxembourg in 2026.
Good to know: renovation + insulation = grant. Façade renovation on its own is not subsidised, but combined with external wall insulation (ITE) it becomes eligible for the Klimabonus. Estimate the gain with our aid calculator.
Why and when to renovate your façade?
Façade renovation is not just a matter of appearance. A deteriorated façade lets moisture in, encourages cracks and degrades the insulation. You typically renovate a façade:
- When the render cracks, blisters or crumbles;
- When damp patches, moss or dirt appear;
- Before a sale, to add value to the property;
- Ideally at the same time as external insulation, to share the scaffolding and the works.
The price of façade renovation in Luxembourg
The price depends on the chosen finish and the condition of the substrate.
| Finish | Indicative price (per m²) |
|---|---|
| Façade paint | €25 – €45/m² |
| Single-coat render | €30 – €80/m² |
| Roughcast | €30 – €90/m² |
For a house with around 100 m² of façade, budget:
- €6,000 to €9,000 for a full repaint;
- €9,000 to €15,000 for rendering.
Preparatory work (cleaning, crack repair, anti-moss treatment) and scaffolding hire have a strong influence on the quote.
Permits: don’t skip this step
In Luxembourg, renovating a façade involves administrative procedures:
- Work declaration: in Luxembourg-Ville, a declaration must be submitted to the mayor at least 10 days before work begins for any renewal of the surface finish.
- Protected zone (conservation area): if the property is in a protected zone, a full building permit is mandatory. It can extend the timeline by 4 to 8 weeks and impose specific materials (lime render, prescribed colours), which increases the cost of the project by 20 to 50%.
Always check with your municipal administration before launching the project.
3% VAT on façade renovation
Good news: façade renovation benefits from the super-reduced 3% VAT rate (instead of 17%) for homes completed at least 10 years before the date of the work. Main residences, second homes and rental properties are all eligible — a substantial saving on the total budget.
The tip: combine renovation and insulation
Since the scaffolding is already in place, it is the ideal moment to add external wall insulation (ITE). You then get:
- a brand-new façade and significantly improved energy performance;
- access to the Klimabonus (up to ~€115/m² of insulation) that façade renovation alone does not offer;
- a single job instead of two, with logistical savings.
