Mengeder Fensterbau und Glasbau GmbH

A business that provides extremely high quality service with its professional staff.

A highly competent company! The work was carried out quickly and professionally. All contacts were very friendly and reliable. We can wholeheartedly recommend Mengeder Fensterbau.

I'm very satisfied! I had Mengeder Fensterbau manufacture and install all the windows, doors, and shop windows for my building at Hannöversche Str. 7 in Dortmund. From the initial measurements to the final installation, we received professional and competent support throughout the entire process! I highly recommend them! We're already planning our next project with them!

Just before the holidays: My patio door—whose locking mechanism hadn't worked properly for years—suddenly wouldn't close completely. And it wouldn't open at all. Among other things, this blocked access to the garage... A quick internet search, a call to Mengeder Fensterbau: "Okay, we can be there in two hours." Relief... Two hours after the two skilled technicians entered my house, the entire door mechanism had been replaced, and it opened and closed as smoothly as it hadn't in what felt like decades. PERFECT!!!

Five years ago, we replaced two glass sliding doors and a total of ten windows. Everything was handled very professionally. Mr. Baris Acikgöz gave us excellent advice and listened to our wishes. Technically, I give him a 10 out of 10. Personally, I give him a 10+. Today, we ordered our new windows from Mengederglasbau and had them installed. Once again, everything went very professionally. The employees are very experienced and work cleanly. Thank you very much.
