Quick Answer
Winterize an off-grid cabin by inspecting and repairing roofs, gutters, and downspouts, and preparing plumbing, electrical, and HVAC systems for freezing temperatures. Disconnect and drain hoses, and cover or insulate exposed pipes. Seal gaps and cracks in windows, doors, and walls.
Preparing Plumbing Systems
Inspect your cabin’s plumbing system, paying close attention to exposed pipes in unheated areas such as the crawl space or attic. Disconnect and drain hoses from outdoor faucets, and consider installing frost-proof spigots. Use foam pipe insulation to cover exposed pipes, and wrap or tape them with heat tape or thermostatically controlled heat cables for added protection.
Insulating and Sealing the Cabin
Check the cabin’s insulation levels, particularly in the attic, walls, and floors. Add insulation as needed to maintain a minimum of R-19 in the walls and R-30 in the ceiling. Seal gaps and cracks in windows, doors, and walls with weatherstripping, caulk, or spray foam to prevent cold air from entering and warm air from escaping.
Preparing HVAC and Electrical Systems
Schedule a professional inspection of your cabin’s HVAC system to ensure it’s in good working condition. Consider installing a whole-house humidifier to prevent pipes from freezing. Also, inspect and clean your cabin’s electrical panels and outlets, and ensure that all electrical connections are secure and waterproof.
