Cambridge | Dramatic Staircase This Old House : Season 27 Episode 12

Host Kevin O'Connor arrives to find exterior coatings specialist Dan Rourke and his crew applying the EIFS finish coat. Custom pool specialist Bob Snay installs a black pebble finish on the bed of the new water feature. Inside, general contractor Tom Silva oversees the installation of the steel stairs. Kevin visits the custom metal shop that fabricated the steel as well as the dramatic bronze "wishbone" balustrade that will be installed later on the job. Reclaimed wood specialist Richard McFarland shows Kevin samples of reclaimed wood from all over the world as Tom's crew installs exterior redwood siding harvested from giant olive casks. Plumbing and heating expert Richard Trethewey gives Kevin an update on the mechanicals — the new boiler has arrived, radiant panels are installed underneath the first floor, and PEX water supply lines have been run.
