Had 6 windows installed 11/2019 . Noticed fine scratches on window fraims . They stated they would had to have a factory rep come out and look at them. A few months after that corona hit. 4 more months went by we called and they said they will replace them great! 3 more months went b they stated corona has slowed product we understand that .now we are calling once or twice a week he's in a meeting or out of office he will call you and call no call backs.. still waiting 13 months later and no calls or replacement windows.This was only half the house . I don't think they will be getting the other windows we need in this house. Verry disappointed with our owner rep.. not what he promised he would do. One sad and scratched window world customer in Troy Mi. We never expected this from them. read more
