ABC siding gave us a life time warranty for our patio doors. We had trouble with the screen door thinking it was the rollers so we tightened them up. It turned out to be that the track was broken. Three years ago I called them telling them I had a life time warranty and would like someone to come out. Finally this year they came and took pictures. Because this company no longer has this type of doors then can not warrant my door. They also states that since we cannot prove we didn't hit it with a shovel they will not guarantee this door. We have a wooden deck connected to this door and we never use a shovel on it. Three years ago were they still making this door? What good is a life time warranty if they won't honor it!!
