Replacing an inadequate foundation and a pitched basement slab; uncovering a secret ceiling.

Working around the antique fieldstone foundation, Kevin and Norm find Tom and mason Mark McCullough replacing the inadequate foundation under the addition and pouring a new slab in the basement with a concrete curb to bolster the walls. Breaking through the living room ceiling, they discover a lot more headroom, along with the original plaster molding and medallion, almost completely intact.
