Workers were very friendly, they came very quickly and fixed my problem.
I changed my old broken window to a complete new system window with a cat door, the Duma, is such an efficient team, you can easily reach them through call or Whatsapp. The quality of the window is top! The install team is super polite, friendly too. I highly recommend them!
Perfect very professional, very organized company most of all very friendly people. And a quick repair. Verhagen
I hired DuMa to replace 2 windows and a balcon door. I am very satisfied on all fronts. The offer was slightly cheaper than competition. The communication was very nice too: through the whole process DuMa explained in detail what they would perform. The end result is clean and precise. The execution was fast thanks to good coordination and team work from the DuMa team. I also appreciate that it was possible to communicate both in German and English. I highly recommend DuMa's services!
