Update by user Apr 21, 2021 Alside has not responded to any inquiries, they are doing absolutely nothing. Original review posted by user Mar 22, 2021 Purchased 36 "Premium Deluxe Vinyl Replacement Windows w/Climatech Glass" through Kroll Construction. Windows were manufactured by Alside Windows, an Associated Materials company. Windows include a LIFETIME warranty. Filed a claim due to a crack in a window frame (left pane) that was the result of the lock and receiving side of the lock not aligning properly, Alside denied the claim. The left pane has a cracked frame and the right pane cannot even lock since the window appears to be sitting askew. Has to be either a manufacturing defect or installation defect. Kroll Construction instructs me to file a claim with Alside, Alside dismissed the claim, neither Alside nor Kroll will take responsibility for a poorly manufactured/installed window. User's recommendation: AVOID ALSIDE WINDOWS!!!
