I am in the market to replace ALL of my windows in my home. I'm going through the process of getting quotes from 3 vendors. Welda windows was on my list. I called to set up an appointment. It was for a Friday at 8pm. I went out with friends on Friday and made sure I left early to make it home by 7pm in order to wait for the window guy. Welda called in the am on Friday to confirm the appointment. 8pm passed as did 9pm. The Welda representative DID NOT SHOW UP nor did anyone from the company call to tell me there was a problem. I thought they may call the next day to tell me there was an emergency but they did not even do that! They just lost 7-10K worth of business.
