Arborist Matt Foti and crew remove a large swamp marple from the site. Tom Silva takes us to see another, simpler ranch expansion he did in a nearby town. Back at the site, our master carpenter and host discuss the new polystyrene insulating foundation forms Ken Lewis is installing; then the concrete is pumped over the house and into the completed forms. Later, our host checks in to see the slab poured and termiticide applied to the new foundation's perimeter.
