That last weekend at the camp can feel like a simple routine: pack up, shut off a few things, lock the door, and head home until spring. However, closing a seasonal home for a Maine or New Hampshire winter takes more than that.
With no one around to catch problems early, a vacant camp can develop serious issues. A frozen pipe can rupture, a small roof leak can go undetected, and moisture can collect in an attic. By the time you return in the spring, that small problem becomes a much larger project.
Because of that, proper camp winterization matters. The good news is that most of the important steps are straightforward. Here is a practical second home closing checklist to follow before you lock the door.
1: Why Closing Right Matters More Than You Think
The 24–48 Hour Problem
For a vacant camp, even a small leak can become a bigger issue when no one is there to catch it. The CDC recommends drying wet materials within 24 to 48 hours when possible because prolonged dampness can support mold growth.
This is especially important in Maine, where about 16-17% of housing is seasonal. A leak that starts in November could go unnoticed until spring, leaving moisture for months.
Water Doesn’t Care If Nobody’s Home
A pipe can still freeze whether the property is occupied or empty. The same is true for slow plumbing leaks, failed appliance connections, roof seepage, and water entering through vulnerable exterior areas.
Because no one is there to respond, even a small amount of water can continue spreading. Shutting off and properly draining the plumbing is therefore one of the most important parts of your camp shutdown for winter.
What Winter Does to Neglected Homes
Maine and New Hampshire winters also create several risks at the same time. Freezing temperatures can affect plumbing, while repeated freezing and thawing can stress roofs, gutters, foundations, and exterior openings.
Roof and attic conditions deserve particular attention. Uneven roof temperatures can also lead to snow melting and refreezing, increasing the risk of ice dams.
2: Before You Close the Door — The 3-Hour System Shutdown
Water & Plumbing (30 minutes)
If your plumbing setup allows it, shut off the main water supply before leaving. Then open appropriate faucets and drain vulnerable lines so water is not left sitting in areas that may freeze.
Some seasonal homes may also need more extensive winterization, particularly those with well systems, sprinkler systems, or plumbing that cannot be fully drained. In those cases, have a professional winterize the system.
HVAC & Heating (20 minutes)
If you are leaving the heat on, start by confirming that the thermostat is working and set to a temperature that protects the plumbing. During cold weather, keep a vacant home at no lower than 55°F.
Lowering the thermostat can reduce energy use, but the savings are not worth increasing the risk of frozen pipes. Instead, keep the temperature at a safe level and, if your system supports remote monitoring, check the temperature while the property is vacant.
Appliances & Moisture Sources (20 minutes)
Clean and dry appliances that will be shut down for the season. For the dishwasher, clear food debris and leave the door slightly open after the final cycle. If a refrigerator will be unplugged, clean it thoroughly and leave the doors propped open.
Check washing machine connections and shut off the supply if recommended for your setup. Empty the ice maker when required, remove food that could spoil or attract pests, and run the garbage disposal with water to clear remaining debris.
Sump Pump & Basement Prep (10 minutes)
Test the sump pump before you leave, confirm that the discharge line is clear, and check that water can move away from the property. If you have a battery backup or other backup power, test that system too.
At the same time, look for damp walls, standing water, staining, or musty odors. Existing moisture should be addressed before the camp is left vacant.
3: Reader Question: “Can I Just Turn Down the Heat to Save Money?”
You can lower the temperature to reduce energy use, but not so far that the property is at greater risk of freezing. During cold weather, keep a vacant home at 55°F or higher to help protect the plumbing.
Heating costs vary depending on the home, insulation, and heating system, but small savings may not be worth the risk of a frozen pipe and the water damage. For that reason, use a programmable or connected thermostat that can help maintain a temperature and also allow you to monitor the property remotely.
4: The Roof & Gutters Inspection (Before the First Snow)
Ice Dam Prevention Checklist
Clean leaves, pine needles, and other debris from the gutters so melting snow has a clear path to the downspouts. Make sure the downspouts direct water away from the foundation.
From a safe location, look for obvious roof problems and check the attic for signs of inadequate insulation, poor ventilation, or previous moisture.
Shingle & Flashing Assessment
Look for missing, loose, or damaged shingles. Check flashing around chimneys, vents, skylights, and other roof penetrations for visible cracks or gaps.
A small repair now can help prevent water from entering attic or ceiling materials during winter storms. Then, when you are ready to open the camp again, you can start the season without discovering unexpected water damage.
Roof Raking & Snow Load Limits
Do not judge roof safety by snow depth alone. Wet snow and ice can weigh substantially more than fresh, dry snow. Moreover, roof design, pitch, condition, and the distribution of snow also affect the load.
That’s why, if the camp will remain vacant, arrange for a trusted neighbor, property manager, or other local contact to check the property after major storms. If there is heavy accumulation or another sign of structural stress, have the roof assessed.
5: Interior Moisture Control (Often Overlooked)
Dehumidifiers & Air Circulation
Where appropriate, leave interior doors slightly open to encourage airflow between rooms.
A dehumidifier can also help in a basement or crawl space when it is suitable for unattended use and has a safe drainage setup.
Cabinet & Pipe Access
During severe cold, opening cabinet doors under sinks can allow warmer indoor air to reach exposed plumbing, especially when pipes run along exterior walls.
This is a useful precaution, but it should support proper winterization rather than replace it. If the plumbing system is meant to be drained, follow the full shutdown procedure for the property.
Identifying Hidden Moisture Risk Areas
Before leaving, inspect crawl spaces, uninsulated areas, attics above unheated porches, basement corners, under sinks, and areas where you have seen condensation or water staining before.
A musty odor, discoloration, peeling material, damp insulation, or visible staining should be dealt with before the property is left for the season.

7: The Departure Checklist (Last 15 Minutes)
Windows & Doors
Once the major systems are handled, finish with a final walkthrough. Confirm that all windows and exterior doors are closed and locked.
Look for obvious drafts or damaged weatherstripping and address any gaps that could expose the interior to winter conditions.
Exterior Doors & Crawl Space Access
Check crawl space doors, basement access points, utility openings, and other exterior areas for gaps.
Seal obvious entry points where appropriate. Rodents and other animals can damage insulation, wiring, ductwork, and other materials while also introducing moisture and contamination.
One Final Walk-Through
Listen for dripping water and check under sinks, around plumbing connections, and along ceilings for fresh staining. Pay attention to any unusual musty odor.
If you suspect a gas leak, follow your utility provider’s emergency instructions and avoid creating sparks or operating electrical switches in the area.
Finally, photograph the property’s general condition, utility areas, meter readings, thermostat display, and any existing wear or damage. That gives you a useful record to compare against when you return in the spring.
8: Reader Question: “Should I Hire Someone to Check On the Property Mid-Winter?”
For many seasonal homeowners, a mid-winter check is worthwhile, particularly when the property will be empty for several months. But how often you should visit depends on the home’s age, condition, heating and plumbing systems, and the severity of the winter.
A check every four to six weeks can provide an opportunity to catch problems early. If you cannot visit yourself, a trusted neighbor, property manager, or local contact can check the property and make sure it remains secure.
9: What Happens If Something Goes Wrong While You’re Away?
Emergency Water Damage Response
If a pipe freezes and bursts, a sump pump fails, or water enters through the roof, do not wait. The longer water remains, the more opportunity it has to spread into surrounding materials and cause additional damage.
If something goes wrong while your seasonal property is vacant, you can call Octagon Cleaning & Restoration for 24/7 emergency water damage response throughout Maine and New Hampshire. Our team can respond even when you are not nearby.
After-Hours Protocol
Keep emergency contacts accessible and make sure anyone responsible for the property knows who to call. Octagon uses the same main number for emergency dispatch day or night, so you do not need to find a separate after-hours contact.
When you call, provide the property’s location and any access information, such as a key location, gate code, or lockbox details. Photos and documentation can also help the team understand the situation before arrival.
10: Key Takeaway — Closing Right Saves Thousands
Proper camp winterization is about handling the controllable risks before you leave. Shut down the plumbing correctly. Maintain safe heat. Clear the gutters. Check the roof. Control moisture. Test the sump pump. Document the property’s condition.
Then arrange for someone to check the camp during the winter if it will remain vacant.
