When the Barnwood Builders need a laugh, they turn to Tim Rose and Alex Webb. Tim and Alex share their hilarious journey from mortal enemies to good friends as they save old barns and cabins, learn new skills and marvel at American pioneer history.

Mark finds a barn being torn down in Pennsylvania and buys it on the spot. The crew goes the extra mile to rescue the beams as Johnny deals with overhead wires and Sherman works with one good arm. Later, Mark visits the largest bank barn in the state.
