The teams continue to struggle as their build seasons come to a close. Jackie's team hurries to finish the interior of her cabin, while the Owens team is at risk of not finishing their client's cabin on time. Meanwhile, the Hills brave one more journey to their build site to try and finish before their friends arrive.

Jackie's team hears propane leaking somewhere in their cabin as they install the cabinets and stove. Melting trails makes the delivery of cabinets and appliances dangerous at the Owens' build site, while a chimney installation is not going as planned for the Hills team.

Jackie's team delivers French Doors only to find the frame fits incorrectly during installation. A snow machine delivery runs into problems on the melted trail at the Hill's build site. Meanwhile, the Owens team is installing windows when Kyle slips and falls.

The Owens work to finish the roof, but multiple falling objects and whiteout conditions make the job perilous. Jackie and her team struggle lifting the 250-pound stove from the bay up to the cabin, and The Hills arrive at their build site to find their materials buried under the snow.

The Hills work on their first floor framing, but work slows to a stop when their tools begin to freeze. The Owens work on installing the second story gables, while Jackie and her team work to finish the cabin's roof structure.

The Hills race to finish installing their floor to avoid a delivery delay, which leads to an on-site injury. Meanwhile, Jackie and her team run into problems when their build materials start to fall apart, while the Owens struggle to install flooring before possibly being buried by a snowstorm.

At Jackie's slippery build site, the team works to finish the subfloor and start raising walls, but rain and mud hinder them at every step. Meanwhile, the Hills are forced to dig their supplies out of three feet of snow, while the Owen family works to overcome missing pieces of their log walls.

Three new teams begin their projects; Matt and Amy Hill realize building in snow is complicated; Mike and Dan Owens mill the lumber needed for their build; Jackie Keizer hires a team that struggles to bring out an excavator to dig her foundation.
