This Old House - Season 19 Episode 4

Our master carpenter lays out lines for subslab ductwork in his workshop, and the crew strips off the barn's old shingles. They will use a shingle panel system when they replace the siding. Tom Silva shows us his new jobsite trailer, leased complete with office and secure storage room. A surveyor works to put together a certified plot plan, while we see the excavation work around the main house for the kitchen foundation and for a perimeter drain along the front rubblestone foundation for years. In the barn, our master carpenter puts in one of the new post to make room for the garage to come - earlier he used new one-piece footing forms and a waterborne lazer level to provide solid bases for the new posts, poured by a small-batch concrete delivery truck. In the future media room, the crew removes the lally column, holding up the building with jacks and a cripple wall before inserting a flitch beam of laminated veneer lumber and steel.
