David: This Old House Episode #2709
Host Kevin O’Connor sees how landscape contractor Roger Cook is building the fieldstone and mortar sitting wall. Meanwhile, master carpenter Norm Abram shows homeowner Paul Friedberg troublesome conditions with the wood-to-ground contact on the side of the house, underneath the front porch, and at the garage. Pest control expert Bill Seigel comes to the rescue with a treatment to stop the termite activity and prevent further damage. General contractor Tom Silva shows Kevin the new stepped dowel fastening system he is using to put down the ipe decking. Architect Treff LaFleche takes Kevin to see a riff on the Shingle-style brand new home he designed that looks traditional on the outside, but features clean, wide open, modern spaces on the inside. Up in the attic, plumbing and heating expert Richard Trethewey shows Norm the air handlers, and how the high velocity mini-duct system lets him easily feed conditioned air to the second and third floors.
