Landscape contractor Roger Cook removes the rest of the old plants and dead lawn to make way for the new, while homeowner Liz Bagley and interior designer Lisey Good show off their plans for decorating the more modern downstairs unit. Upstairs, cabinet installer Oliver Earl shows master carpenter Norm Abram the new cabinets going into the kitchen. Plumbing and heating expert Richard Trethewey visits nearby Boston Light, the site of the first lighthouse in the country, to see its newly restored Fresnel lens. General contractor Tom Silva shows host Kevin O'Connor how he's expanded the back porch using composite decking with a hidden fastening system, and how he's repairing an old pressure treated railing, rather than replacing it. Flooring contractor Patrick Hunt shows Norm a new dust collection system that attaches to a standard floor sander, separates particulate matter through a cyclone, and then funnels the dust to a canister that can be kept outside, leaving the jobsite dust free.
