How to Prevent Pipes From Freezing in a Cabin?
Last updated October 25, 2026
The short answer
Maintain Warmth
Keep the cabin heated to at least 55F, even when you are away. Set the thermostat to a consistent temperature and avoid lowering it at night. If the cabin has zones you rarely use, keep those doors open so warm air circulates freely.
Check for cold spots near exterior walls, crawl spaces, and attics. Add extra insulation to these areas. Where winter temperatures can dip below freezing, a few extra inches of insulation can make a real difference. Use foam pipe covers on any exposed pipes in unheated spaces.
Seal Drafts and Openings
Cold air sneaks in through gaps around windows, doors, and where pipes enter the cabin. Use caulk or spray foam to seal these openings. Pay special attention to the rim joist area in the crawl space, as that is a common entry point for cold air.
Check the foundation vents and close them for winter. If you have a crawl space, consider covering the ground with a vapor barrier to reduce moisture and cold. Sealing drafts not only protects pipes but also lowers your heating bill.
- Inspect caulk around windows and doors
- Use expanding foam for larger gaps
- Close foundation vents before winter
- Add weather stripping to doors
- Insulate the rim joist area
Let Faucets Drip
When temperatures drop sharply, let a few faucets drip slowly. Running water is less likely to freeze because moving water has more energy. Focus on faucets that are farthest from the main water line or on exterior walls.
Collect the dripping water for plants or other uses to avoid waste. If you have a well, make sure the pump and pressure tank are in a heated space. A small drip can prevent a major burst, saving you from costly repairs and water damage.
Drain the System If Away
If you plan to leave the cabin for more than a few days during winter, drain the entire plumbing system. Turn off the main water valve, then open all faucets and flush toilets to empty the lines. Also drain the water heater and any irrigation lines.
Add antifreeze to drains and toilet bowls to prevent traps from freezing. Be sure to use plumbing antifreeze, not automotive antifreeze. This step is especially important for cabins that are not winterized. If you miss a spot, a burst pipe can cause extensive damage.
- Turn off the main water valve
- Open all faucets and flush toilets
- Drain the water heater and lines
- Add plumbing antifreeze to traps
- Close the shutoff valve on the well
Know the Signs of Trouble
If you return to the cabin and find no water when you open a faucet, a pipe may be frozen. Do not use a torch or open flame to thaw it, as that can start a fire. Instead, use a hair dryer or space heater and start from the faucet end.
If a pipe has already burst, shut off the main water valve immediately. Then call local water damage pros to handle the cleanup. They can extract standing water, dry out the structure, and help prevent mold. Acting quickly reduces the damage.

What temperature should I keep my cabin to prevent frozen pipes?
Keep the cabin at least 55F, even when you are away. This temperature is generally safe for most plumbing systems. If you have pipes in unheated areas, consider adding extra insulation or heat tape to those sections.
Can I use heat tape on my pipes?
Yes, heat tape can be effective when installed correctly. Follow the manufacturer's instructions and wrap it evenly around the pipe. Do not overlap the tape, as that can cause overheating. Check the tape periodically for damage.
What should I do if a pipe bursts while I am away?
If you discover a burst pipe, turn off the main water valve as soon as possible. Then contact the pros to extract water and dry the area. They can also help with structural drying and dehumidification to prevent mold growth.
