When they arrived, her two attic hatches were blocked with batt insulation. They cleared the obstruction and inspected the attic. To our surprise, there was over a foot of celluose insulation present. They told us she didn't need any more. When asked if radiant barrier was a good idea, they told us that it wouldn't really make an impact since she already had such good insulation. How about that? A company that REFUSES to sell you something you asked about, but don't actually need! Before they left, the two guys raked it out, placed dams around both attic hatches and properly insulated the backs of the hatches with foam board. They spent over an hour, but only charged me $100! They were honest, on time and a huge pleasure to do business with.
