Zastrau provided me with very good support from start to finish, both in terms of advice and help with open questions. The job of replacing a patio door with additional burglary protection was
carried out professionally. There were absolutely no complaints. Even after the purchase of the new product, you continue to receive good advice. I will be placing my next order with Zastrau again. The price and the top service are right. I can recommend Zastrau to everyone!!!

The very good and competent advice from Mr. Zastrau was the deciding factor for me to choose this product.
The Gayko windows are of very good quality and are easy to handle, just like the exterior blinds.
easy to handle, just like the external roller blinds. After installation, it has become noticeably quieter in the house.
The windows were installed by conscientious and clean workers.
I would particularly like to highlight Mr. Becker and Mr. Rasmussen.
They were always on site during the installation of the WINDOWS and were very motivated during all the work,
friendly and competent.

We needed insect screen elements for several windows and doors. Due to the integrated external venetian blinds, we had extremely little space for this. This made installation extremely difficult and time-consuming. But in the end, Zastrau mastered this challenge to our complete satisfaction. The fact that the windows and doors were measured in advance by Mr. Zastrau himself and again by a Kadeko representative played a decisive role, and then on the day of installation the extremely competent and friendly employees were very imaginative and ultimately mastered even the most difficult windows with a great deal of tinkering talent.
We can fully recommend this friendly company!

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.
