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.
At Jackie's slippery build site, rain and mud hinder the team at every step; the Hills are forced to dig their supplies out of three feet of snow; the Owen family works to overcome missing pieces of their log walls.
The Hills race to finish installing their floor which leads to an on-site injury; Jackie and her team run into problems when their build materials start to fall apart; the Owens struggle to install flooring before being buried by a snowstorm.
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; Jackie and her team work to finish the cabin's roof structure.
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; the Hills find their materials buried under snow.
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 Hills' build site; Kyle slips and falls while the Owens team is installing windows.
Jackie's team hears propane leaking somewhere in their cabin; melting trails make the delivery of cabinets and appliances dangerous at the Owens' build site; a chimney installation does not go as planned for the Hills team.
The teams continue to struggle as their build seasons come to a close; Jackie's team hurries to finish the interior; the Owens team is at risk of not finishing their client's cabin on time; the Hills brave one more journey to their build site.
