Nombach has performed work for myself and other family members. We keep calling Nombach because they do an immaculent job at a reasonable price. There has been no complaints about this company from family members nor myself. I selected Nobach for my windows rather than choosing Feldco who had a bad report card with the BBB. Although Fedco’s proposal was a couple of dollars less than Nombach, I still chose Nombach. I wouldn’t want to deal with a company who might do a poor job and then I’m bothered with trying to get an issue resolved months after he initial work has been done. I would advise…..Choose Nombach.
