Builder Mike Williams and his team gain some ground, but can they keep it while laying plywood over the cabin's foundation in Eagle Song? Dave and Hans try and get reacquainted with their build and it reminds them how little time and how much work they have left on Shelter Island. Builder Adam Tschappat comes face to face with his biggest fear for his cabin's success in the Wrangell Mountains.
Builder Mike Williams' son Cody comes up with a fix for their pressure washer problem in order to peel the logs for their cabin build in Eagle Song. Dave and Hans work through extreme weather fluctuations and muscle heavy beams in place for the second floor on their cabin build on Shelter Island. Builder Adam Tschappat is a bag short of cement to complete the foundation for his cabin and his team worries as he is nowhere to be found in the Wrangell Mountains.
Builder Mike Williams gets all 45 of his logs peeled and starts to stack and insulate his cabin in Eagle Song. Builders Dave and Hans deal with dangerous heavy fog on their boat journey to Shelter Island and struggle to lift heavy logs with limited help. Builder Adam Tschappat saves the day with an extra bag of cement, and he and his team prepare the location and materials needed for the cabin's outhouse in the Wrangell Mountains.
Builder Mike Williams falls further behind schedule due to wet weather and unforseen obstacles in Eagle Song. On Shelter Island, builders Dave Bartlett and Hans Moser get a surprise visit and much needed help to finish the cabin, but they still need to make a trip to town in order to complete the build. Builder Adam Tschappat disassembles his cabin at the log yard and begins transporting it to his build site in the Wrangell Mountains.
Builder Mike Williams and his team get the rafters and roofing underway on his cabin but with no lack of challenges in Eagle Song. On Shelter Island, builders Dave Bartlett and Hans Moser are on their own with setting the extremely heavy ridge beam until help arrives. Builder Adam Tschappat successfully transports all of his logs to his build site in the Wrangell Mountains and gets the massive floor to the cabin laid out.
On Shelter Island, Dave Bartlett and Hans Moser have not one, but two 700-hundred pound ridgepoles to set. Over at Eagle Song, running out of weatherproofing, and a last minute design change, forces Mike Williams to forge ahead in dodgy weather. For builder Adam Tschappat, a faster pace comes to a screeching halt when two crucial logs go missing at his build site in McCarthy.
It's do or die time for all of the builders. The tides become the ultimate decider for Dave, Hans, and Steve, and send Steve to the workshop. For builder Adam and his family, the weather can't dampen their excitement as they finish their legacy cabin build. Over at Eagle Song, Mike is racing the first snowfall, can the family that builds together, stay together?
Three new build teams arrive to their build sites and begin work on their unique cabins in the remote Alaskan wilderness. Josh Tousignant and his crew make the long trip to Cordova to begin building the foundation for their clients' two-story cabin. John Donkersloot and Heather Rough oversee delivery of two 40-foot shipping containers for their cabin's foundation on a mountain build site in Seward. Finally, float plane pilot Chris Maynard and his crew fly out build materials and install helical piers for his cabin's foundation on Trinity Lake.
At Trinity Lake, Chris and Joe battle an 80-foot spruce that begins to fall too soon before a helicopter delivery almost goes wrong. Next, John and Heather fall behind while building the floor of their cabin due to the rain and need help getting back on schedule on Mt. Ascension. Later, Josh and his team must forklift their materials up the muddy driveway to the build site in Cordova after the semi gets stuck at the bottom. Finally, a complex build plan with too many parts and pieces threatens to shut the site down in order to get organized.
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.
All three builds are running behind schedule and must rush to get ahead. John and Heather build a water catchment system but discover they aren't getting enough water pressure, Chris Maynard's windows are delivered by helicopter in a dilapidated crate that swings violently in the wind, and Josh comes dangerously close to tipping over his forklift and knocking over a gable wall.
Time is running out for the builders to complete their projects. At Trinity Lake, Chris Maynard gets help installing solar panels and sets up cameras to watch for bears while Greg and Ivan work quickly to finish the interior tongue and groove paneling for the cabin's roof. Outside Cordova, Josh Tousignant works on the custom log stairs as Jeremy takes his time to precisely cut and build the cabin's custom windows. On Mt. Ascension, John Donkersloot and Heather Rough's build site is flooded, and they must rebuild the road to their cabin. Later, a window doesn't fit, and too much pressure on freshly built custom concrete countertops causes problems.
The builders are in the final push to finish their cabins before winter strikes and forces them to shut down. Josh Tousignant and his team fight the rain and wind to install the wood stove and finish the roofing tin before clients Keith and Kathleen take over to finish their cabin's interior. Chris Maynard and his wife rush to install the kitchen counters and furniture before their extended family arrives for the first time. John Donkersloot and Heather Rough struggle to finish both the exterior and interior of their cabin before the snow falls and their build season is over.
