Absolutely worst experience ever, when I called Wardco to request service because window is not staying open( double hung) I was informed that I bought windows from service man “ Norm “ and not Wardco . All my attempts to contact Norm have failed as he never responded to my messages. When I called customer service at wordco I was faced with rude and unpleasant lady who promised to call but never did. I am continuing to try and solve my problem with no effect . Do not trust or go to them! I have spent lots of money and ended being treated unpleasantly and with avoidance. Do not use Norm as your service man because you will never hear from him again!!
