Building Alaska

Three new couples challenge the Alaskan elements. Mike and Kathleen Kondus build atop a windy tundra, first-time builders Mike and Teresa Oldenkamp construct a complex cabin and Paige Drobny and Cody Strathe create a dog-training facility on haunted land.

Mike and Kathleen begin on the foundation, but their nail gun goes on the fritz and the posts aren't level. Dog mushers Paige and Cody run low on supplies. Mike and Teresa work on their foundation with a damaged excavator.

Paige and Cody realize they don't have the correct insulation for their log walls. Kathleen and Mike's team get dangerously high up to install the ridge beam. Mike and Teresa begin work on their floor, but discover the joists are not evenly spaced.

Mike and Teresa begin building their walls, but the winch is more dangerous than they realized. Paige and Cody use a boom truck, forcing the team to work extra cautiously. Mike and Kathleen find a nasty surprise at the bottom of the mountain.

Mike and Kathleen move to interior work, but the remote location is still slow with progress. At Paige and Cody's site, mechanical failures prevent the project from finishing before dog sled season. As Mike and Teresa build higher, it gets more dangerous.

Paige and Cody's build takes a hit after Sterling and Joe leave the site and a trailer full of vital materials breaks down; the foundation is sinking at Mike and Teresa's cabin while Kathleen and Mike Kondus watch part of the cabin begin to crumble.

The Konduses fight the rain and shattered window panes deep in the White Mountains. Mike and Teresa's team gets stuck on slippery scaffolding 19 feet in the air while Paige and Cody's build stalls thanks to a material ordering snafu near the deadline.

It's a race to the finish as Paige and Cody wrap up before dog racing season in Cantwell while Mike and Kathleen lose all their help deep in the White Mountains. Meanwhile, the Oldenkamps struggle with the challenges of working on a grain-bin-style cabin.
