Who we work with

We offer a partnership to professionals who help homeowners in Luxembourg:

  • Energy advisors: your clients need new windows to meet the Klimabonus requirements.
  • Estate agents: a buyer wants new windows before moving in, or a seller wants to add value to the property.
  • Architects: your renovation project needs made-to-measure windows and doors, measured and installed by one team.
  • Property managers and building managers (syndics): a shared building or a rental home needs new windows, doors or shutters.

What your clients get

  • A free measurement visit at home, with no obligation.
  • A detailed written quote at a fixed price after measuring, with every window listed.
  • Help with the paperwork for Klimabonus and 3% VAT.
  • Clean installation by our own team, in one to two days for a house.

What you get

  • One contact person for you and your clients, from the first visit to installation.
  • Clear documents: a quote that lists every window, useful for your files and your advice.
  • Support in four languages: French, Portuguese, German and English.
