I am really very satisfied with the performance, as:
- short-term delivery of a rough cost estimate received after request.
- honest, detailed and competent on-site consultation without the feeling of being "talked into" something. Advantages and disadvantages of the configuration options were explained. Options for retrofitting were explained
- Due to the competent advice, the result was better than planned/expected.
- Possibility to inspect the windows at Kühn's showroom
- Prompt, uncomplicated implementation
- Options for tax deduction according to EnVE or KfW subsidies were shown and handed out as a leaflet. Entrepreneur declaration, was pro-actively enclosed with the invoice
- Generally very friendly and pleasant communication
- Fair price/performance ratio
I can only recommend Kühn and plan to commission further work.
Thank you very much!
