Closing Your Sebago Lake Camp for the Season: An Owner’s Checklist

Closing a Sebago Lake camp is rarely as simple as locking the door after one last weekend.

A seasonal property may need its water system drained, dock and boat arrangements completed, food removed, heating and electrical systems checked, storm risks addressed, and someone assigned to watch the property after the owner leaves. What belongs on the list depends on the building, its utilities, how late it remains in use, and whether it will be heated through the winter.

The best time to make that plan is before the first hard freeze—and before seasonal service schedules fill.

This checklist will help you organize the work, identify decisions that need professional guidance, and leave a clear record for whoever may need to visit the property during the off-season.

Begin with a property-specific closing plan

No two camps should be closed exactly the same way. An insulated cottage kept at a safe minimum temperature has different needs from an unheated camp with exposed plumbing. A property with a drilled well, septic system, generator, wood stove, seasonal dock, or private road adds its own considerations.

Before scheduling work, write down:

The final planned overnight stay
Whether the building will remain heated or be fully winterized
The water source and location of shutoffs, drains, pumps, filters, and pressure tanks
Appliances or fixtures connected to water
The heating system, fuel supply, electrical service, alarm, and generator setup
Plans for the dock, boat lift, watercraft, outdoor furniture, and equipment
Winter road and driveway access
Who will hold keys and respond to a problem
Any requirements from the property insurer

If several family members use the camp, choose one person to manage the master checklist. A single written plan reduces the chance that everyone assumes someone else drained a fixture, booked the dock removal, or arranged the final property check.

Schedule the work before the closing rush

Camp closing is a season, not a single date. Boats, docks, plumbing systems, chimneys, generators, and cleaning may be handled by different providers, and each can have a different lead time.

Start by contacting anyone whose work must happen in a particular order. For example, a final cleaning may need to occur after the last guests leave but before the water system is shut down. A boat may need to be removed before a dock or lift. A heating inspection should leave enough time for repairs while the property is still accessible.

Owners who want one point of contact can begin with the Camp Opening, Closing & Property Watch Directory. Confirm exactly what each visit includes; “camp closing” can mean anything from a visual inspection and key-holding service to coordination of a complete seasonal shutdown.

Protect the plumbing and water system

Frozen pipes can cause extensive damage, particularly when a building is empty and a leak remains unnoticed. The correct shutdown process depends on the plumbing layout, water source, appliances, heating plan, and any fire-suppression system.

A closing plan may need to address:

The main water supply, pump, pressure tank, and water heater
Interior supply lines and low points
Sinks, toilets, showers, tubs, and exterior faucets
Washing machines, dishwashers, refrigerators, ice makers, and filters
Outdoor showers, irrigation, hoses, and seasonal water lines
Well equipment and any components exposed to freezing temperatures

Maine’s emergency-preparedness guidance recommends that owners who leave a home during freezing weather either arrange for someone to check that the heat remains on or drain and shut off the water system, except for systems that must remain active. Maine DEP’s camp-closing guidance also stresses fully draining seasonal plumbing and preventing winterizing materials from reaching ground or surface water.

Because incomplete drainage can leave water in valves, traps, appliances, and hidden low spots, owners who are uncertain about the system should use a qualified professional. Browse plumbing, heating, and HVAC providers or well, pump, and water services, and ask the provider to document what was shut off, drained, protected, or intentionally left operating.

Never use automotive antifreeze in a plumbing system. Follow the system manufacturer’s instructions and professional guidance for any product proposed for a seasonal water system, and do not discharge winterizing chemicals near the lake, soil, a well, or the septic system.

Decide how the camp will be heated and monitored

If the building will remain heated, the plan should account for power failures, fuel delivery, equipment trouble, and prolonged cold weather. Confirm the intended thermostat setting with the heating professional and insurer rather than relying on a universal temperature.

Before leaving, consider whether the property needs:

Heating-system inspection or maintenance
Fuel delivery and automatic-delivery confirmation
Generator service and a safe operating plan
Low-temperature, power-loss, water, or smoke alerts
Fresh batteries in applicable detectors and sensors
A local person who can respond when an alert occurs

Remote monitoring is useful only when someone receives the alert and has authority and access to investigate it. Test devices before leaving and confirm what happens if the internet, cellular connection, or electricity fails.

Use the electrical and generator directory or plumbing, heating, and HVAC directory when the work involves systems beyond routine owner maintenance. If the property has a fire-sprinkler or monitored alarm system, do not shut it down casually; consult the appropriate service company, insurer, and local fire authorities about the requirements for that system.

Arrange dock, boat, and waterfront work

Decide early what must come out of the water and who will do it. Timing can depend on weather, water levels, equipment access, marina schedules, and the design of the dock or lift.

The waterfront list may include:

Dock sections, ramps, floats, anchors, and hardware
Boat lifts and personal-watercraft lifts
Boats, motors, batteries, fuel, and trailers
Kayaks, canoes, paddleboards, and life jackets
Moorings or other seasonal equipment
Waterfront furniture and loose items exposed to wind or ice

Maine DEP recommends storing removed docks and boats where they will not damage shoreline vegetation. It also advises completing engine winterization, washing, and oil handling away from the water so pollutants do not reach the lake.

Find help through the dock and waterfront contractors directory and the boat repair, winterization, and storage directory. Ask what is included, where items will be stored, whether transportation is available, and when spring installation or pickup should be reserved.

Inspect the roof, drainage, trees, and shoreline

Walk around the property before leaves, ice, and snow make problems harder to see. Look from the ground for damaged roofing, loose trim, blocked drainage, leaning or damaged trees, erosion, washouts, and anything that could direct water toward the building.

Do not climb onto a roof or attempt hazardous tree work yourself. Photograph concerns and arrange an appropriate inspection.

For exterior work, browse:

Shorefront work may require state or local review even when it appears minor. Maine DEP advises contacting the local code-enforcement officer and the department when erosion repairs, retaining walls, riprap, or structural work go beyond minor maintenance. Avoid stripping away the natural layer of leaves and pine needles beneath shoreline trees; that layer helps slow and filter runoff.

Remove food and discourage pests

An undisturbed camp can offer rodents and insects food, nesting material, and shelter. Remove perishable food, trash, pet food, birdseed, and other attractants. Clean cooking surfaces, inspect storage areas, and look for openings around doors, foundations, vents, utility penetrations, and rooflines.

Maine DEP recommends closing entry points and removing food sources rather than relying on poisons that could affect pets or wildlife.

If you see droppings, nesting, damaged wiring, persistent insects, or an opening you cannot safely seal, consult the pest-control directory or the handyman and property-repair directory.

Clean, inventory, and document the property

A final clean helps prevent odors, stains, mold, and pest problems, but it also creates a useful baseline for the winter. Once the closing work is complete, photograph each room, the mechanical areas, exterior elevations, shoreline, dock-storage location, and any existing damage.

Consider recording:

The date the camp was closed
Who completed each service
Meter, fuel, thermostat, or system readings when useful
Water and electrical shutoff status
Items removed or placed in storage
Doors, windows, gates, and outbuildings secured
Photographs of the final condition
Unfinished repairs and spring follow-up items

The cleaning services directory can help with seasonal or deep cleaning. Owners of rental properties may also need the vacation-rental cleaning and property-management directory.

Create an off-season property-watch plan

Closing day is not the end of property care. Wind, heavy rain, power failures, falling branches, freeze-thaw cycles, snow, and unauthorized entry can affect an empty building throughout the winter.

A useful property-watch agreement should answer:

How often will the exterior and interior be checked?
What specifically will be inspected?
Are visits scheduled, weather-triggered, or both?
Will the owner receive photographs or a written report?
Who responds to alarms, low-temperature warnings, or water alerts?
What spending authority does the caretaker have in an emergency?
Who arranges snow access, fallen-tree removal, or urgent repairs?
How are keys, codes, and contractor access managed?

Check the owner’s insurance policy for vacancy, temperature, inspection, and notification requirements. A casual drive-by may not satisfy the policy or provide the interior checks the property needs.

Compare options in the Camp Opening, Closing & Property Watch Directory.

A simple final walk-through

Immediately before leaving, complete one last property-specific walk-through. This is the time to verify—not assume—that the planned work was finished.

Confirm water, heat, electrical, fuel, alarm, and generator settings
Check that windows, doors, sheds, and access points are secured
Remove remaining food, trash, liquids, and freeze-sensitive items
Bring in or secure outdoor furniture and loose equipment
Confirm boats, docks, lifts, and waterfront items are handled
Photograph the interior and exterior condition
Test alerts and confirm the correct people receive them
Leave safe access instructions with the designated local contact
Record the next scheduled property check
Keep the closing report and provider contacts where authorized family members can find them

Do not post publicly that the property is vacant, and share keys, codes, alarm details, and shutoff information only with people who need them.

Close carefully now, reopen more easily in spring

A thorough fall closing protects more than pipes and furniture. It protects the owner’s time, reduces unpleasant spring surprises, and gives local contacts a clear plan when winter weather reaches the lake.

Start early, tailor the checklist to the property, and bring in qualified help for work involving plumbing, heating, electricity, fuel, docks, trees, shoreline stabilization, or other specialized systems.

When you need local help, browse the complete Lake Home & Camp Services Directory or go directly to Camp Opening, Closing & Property Watch. Service areas and availability can change, so confirm the details directly with each provider.
