Nordik Windows And Doors

My dealings with Nordik are by far the worst experience I've had with my home renovations. The day of my window installation, one of my windows was missing. I received multiple explanations/excuses for it. Also, the windows that were installed had different locks, one had a damaged frame, the hardware on one of the doors was faulty and it was installed crooked, and there were exterior workmanship issues. I was told that everything would be fixed and completed. I had to follow up multiple times to secure an inspection date and a subsequent work date. There was a complete lack of communication within the Nordik customer service team. A repair person was eventually scheduled after several weeks of waiting. He showed up with no idea of the repair issues that he needed to address. He did not have enough time to do what was needed. I had to follow up again with Nordik to reschedule another repair visit. Thankfully I held back 13% of my final payment as I did not trust Nordik to address all of the deficiencies, and I did not trust the quality of their products or workmanship. I continue to have issues with my windows. Two windows do not open properly, one does not fully lock, and the door hardware is still faulty. Nordik is not interested in addressing these issues. Rather, they are hounding me for this 13% holdback and refusing to deliver their warranty.
