The Cabin Masters take on a historic clammers' shack that's one nor'easter away from falling into the creek. Ashley joins the boys for a renovation that consists of opening up boarded windows as well as clearing out animal droppings, years and years of trash and old machinery. In order to make a big transformation without changing the outside look, the Masters have to get creative while battling the rising tide that touches the camp. The team has their work cut out for them with this rebuild and they know everyone in town is watching closely as they work on this historic landmark.
