Fiber cement and window replacement Lake Mitchell Customer's Problem: The home had rotting and failing siding. The old windows were not thermally efficient. An old tool shed was falling apart next to the home. Service: Alpha Building Services removed all of the existing siding and windows. The siding was replaced with James Hardie fiber cement siding (Thatch in color). Thermal Line composite windows were installed to take care of the cold wind coming in off the lake. Alpha installed fiber cement siding on a new tool shed for the property. © 2003-2010 Alpha Building Products. All Rights Reserved.
