Master carpenter Norm Abram continues work on removing the old clapboards, while out back at the new addition, general contractor Tom Silva and mason Mark McCullough carefully open up a hole in the old fieldstone foundation that will connect the old basement space to the new. Inside, host Kevin O'Connor finds window restoration specialist Alison Hardy and her crew removing the historic sashes to be taken off site for rehab. Plumbing and heating expert Richard Trethewey visits the local library to see the oldest existing flag in the country, the Bedford Flag, first hand. Back at the project house, Tom shows Kevin a rotted sill that he found during demo and explains how he plans to patch, rather than replace it. The footprint of the addition starts to take shape as Tom forms the new foundation out of ICFs. At the end of the day, a concrete truck arrives for the pour.
