I called them because my siding was ripped off by the wind storm this past month and my windows were in bad shape. Since this is their specialty and they manufacture their own windows and have special siding panels that won't rip with the wind, I figured I'd go with them. They replaced my windows within 2 weeks (1 day installation) and my siding was complete within a week. I like the work and I believe the house down the street likes it too since they used Alpha about two weeks later. Price was good too.
