Façade cleaning — methods and costs in Luxembourg at a glance
Dirt, moss, pollution stains: professional façade cleaning brings render or stone back to its original look. The price is per m² and depends mainly on area, access height and the treatment chosen — cleaning alone or with a water-repellent coat.
On this page: why to clean in 2026, the real Luxembourg price ranges, and how to receive two comparable quotes within 24 hours — free of charge.
Why clean your façade in 2026: more than just clean
In Luxembourg the façade takes rain, frost and pollution all year. Cleaning it in time costs a few thousand euros — repairing it too late often costs ten times that.
Your house regains value
The façade makes the first impression, at a viewing and at a valuation. A clean exterior weighs directly on the perceived value of your property.
You protect the render
Moss and dirt hold damp and crack the render when it freezes. Repairing costs around ten times more than cleaning in time.
The water-repellent coat makes it last
Applied after cleaning, it beads the water off and slows re-soiling. Your façade stays clean several years longer.
Sometimes it is even an obligation
Some co-ownership or planning rules require regular façade upkeep. Your companies know what applies at your address.

Façade cleaning: your questions
How much does façade cleaning cost?
Expect €15 to €45 per m² depending on condition, height and treatment (cleaning alone or with a water-repellent coat). Your two quotes price your exact surface.
Cleaning or re-rendering?
Cleaning removes dirt, moss and pollution. Re-rendering repairs and recoats. Your companies judge what your façade actually needs.
Is the water-repellent treatment worth it?
Yes, it protects the façade from water and slows re-soiling. It is priced separately in the quote.
How long does it last?
A clean with a water-repellent coat keeps the façade clean for several years, depending on exposure. Your companies give you a realistic estimate.
How many companies will contact me?
Two at most. Never 5, never 27. It is written into our contract.
Is it free for me?
Yes, €0. HomeUpdate is paid by the trade companies, never by homeowners.
