It is wall-to-wall subs today. Everyone from the tile guy, to the fireplace guy, to the painter, to the granite-pillar guy - that would be landscape contractor Roger Cook - are at the Concord Cottage. Host Kevin O'Connor checks out Roger's latest pro... (more)ject: installing granite bollards in front of the barn door to prevent vehicles from accidentally backing into the barn, while also adding lots of old time character. In the front hall, tile contractor Joe Ferrante is prepping the radiant deck for tile with thin set first then cement board. In the living room, chimney specialist Mark Schaub shows Kevin the new remote controlled gas fireplace that can be vented up or straight out, via an exterior wall, and installs in about one hour. At Boston's Design Center, Kevin meets interior designers Tricia McDonagh and Charles Spada to see the antiques they've selected, and are still considering, for the cottage. Then back at the site, Kevin lends master carpenter Norm Abram a hand installing the sliding windows over the kitchen sink.
