I used to use a different brand of windows through years of rentals and fix-and-flip properties. But after retirement and needing to replace the windows in my own home, I went with Alside, as it seemed to be the right fit. My installation company was fantastic—the windows, however, were shoddy and had problems within a year of being installed. Our first cold snap resulted in cold drafts, fogging and even cracking of some windows. The warranty apparently did not cover any of these problems. It seems that Alside passes off faulty windows to their builders and distributors and that they collude to shield each other from any warranty issues that arise.
