Our house is over 50 years old and needed an update to the clapboard exterior. We love the look of stone, but with an old frame house and no basement, we didn't have a foundation that would support the weight. Gerry brought us samples if his product which is a urethane foam panel that totally looks like stone! As Do-It-Yourselfers, we wanted to do the install. He totally encouraged that and helped us get started on a great transformation. This product works inside or outside the house - anywhere you need a stone look but can't support the weight, or don't want the hassle of dealing with mortar and concrete. It goes on with construction glue and a few screws. We have had so many compliments and we haven't even finished the rest of the project yet! Gerry is a great guy! Very helpful.
