Top. Super reliable, fast, precise, competent and very friendly! Mr. Greiter was sent by the property management, quickly analyzed everything and was able to make the balcony door usable again immediately. We sincerely thank you for the great work!

Mr. Greiter came to us to readjust our windows. He was very polite and nice and was able to provide a timely appointment at my request (due to the cold season and the drafty windows). Very good communication, he informed me when he could come over and was punctual for the appointment. He was so quick that he could not only check our problem windows but ALL windows. I am very satisfied!

We have been working very well with Mr. Greiter for several months. All work has been completed to our utmost satisfaction so far! The price-performance ratio is also right.

Mr. Greiter quickly and efficiently adjusted our large, heavy swing doors to the balcony. Since then, they have been functioning perfectly and effortlessly. The heavy front door of our apartment building had various problems; sometimes it wouldn't open at all, and despite all previous attempts, it fell into the lock too quickly. It is also functioning perfectly again after his intervention. I would call him again immediately if a window or door gets stuck.
