Watch This Old House Season 16 Episode 4 Online

We tour the newly demolished back areas of the house, and see how woefully underframed they are. In preparation for the new foundation, the crew suspends the gable end of the old house with ""pins"" of engineered lumber supported both inside and outside the building. Herb Brockert removes part of the old rubblestone foundation, and a small-batch concrete delivery truck pours footings for the addition's lally columns. Steve revisits the Gallants' Victorian to see how they're liking it. A few days later, a performed concrete foundation system arrives on site and is swung into place with a crane. Soon, a transit truck arrives and the crawlspace gets a slab as part of the foundation system.
