Chris Maynard and team prepare for two intense helicopter deliveries of roof rafters, and Greg precariously scales a raised rake wall to nail it into place. John and Heather are finishing the roof by installing insulation and metal sheeting when the forklift won't shift gears and threatens to knock over their timber frame. Josh and his team work from jagged pallets and rickety ladders late into the night to finish the three gable walls for Keith and Kathleen's cabin.

John Donkersloot and Heather Rough's build is put on pause as they try to figure out how to install their drywall without covering their timber frame. A new team member comes to their rescue to help them finish framing their walls, and they get a late delivery of lumber to finally finish the decking system. Chris Maynard's windows spin violently in the air during delivery, Joe and Duane install the metal roofing tin on a steep slope, and the team works on finishing the insulation and tongue and groove walls before Chris runs out of time and money. Between the rain flooding the inside of the cabin and bears eating their supplies on-site, Josh Tousignant and his team also have to contend with breaking tools and winter looming, so Josh hires additional crew to help him finish the roof system, dormers and deck.
