Recommendation
The communication with the window change company went smoothly, despite my limited proficiency in German. They effectively understood my requirements and provided valuable recommendations.

The installation process was swift, and the workers displayed utmost professionalism while executing the task. I would recommend Zastrau GmbH.

"I am highly satisfied with the work your employees did to replace the balcony door. They worked extremely cleanly and very quickly and were also very friendly. What I also noticed very positively was that the work site was cleaned very neatly and everything was left in a very clean condition. Thank you very much for that! 🤩🙏"

We were very satisfied, from the consultation to the execution of the work. The employees were very correct and friendly and worked until 6 p.m. on Friday to finish the job. What tradesman still works at that time on a Friday. Good work ethic.

Uncomplicated communication and advice in advance. The installation or execution without any complications. The awning was installed after a little over 2 weeks after ordering / consultation. Much faster than previously promised. This is just top!!!

Thank you very much for your cooperation 🤝🏼
We are glad to have convinced YOU of our efficiency from the very beginning.
There will certainly soon be "imitators" in the house - after all, it was not the first awning at this and the neighboring object(s) ☺️
