Because a promised appointment that isn't kept and the work that isn't completed can hardly lead to a good rating.

We are very happy with everything from the initial consultation and cost estimate to the final inspection and invoice, which was even cheaper than expected. If we ever need anything again, we would definitely use Rossmann again. The owner and all the employees are very friendly and do a fantastic job. Thank you so much for our beautiful new bathroom.

We had our gas boiler replaced by Rossmann and are completely satisfied. From the initial contact to the final installation, communication was always respectful, prompt, and easy to understand. All appointments were reliably kept, which is not always the case these days. The installers worked very cleanly and proved that they can handle even tricky situations with ease. Thanks to their creative solutions, everything went smoothly and efficiently. We wholeheartedly recommend Rossmann and thank them sincerely for their excellent work!
