Closing a Tilton camp or lake house for the winter, or opening it back up in the spring — done methodically, documented in writing, so nothing gets missed and nothing splits in February.
Tilton and Northfield share the river, a village center, and a water and sewer arrangement that’s unusual for this region: much of the built-up area on both sides has public water, and the sewage goes into the state-run Winnipesaukee River Basin Program system. For plumbing that means a lot of Tilton homes have municipal pressure, a curb stop at the street, and a main shut-off in the basement rather than a well and pressure tank — a different set of problems and a different set of solutions.
The village housing is old. Tilton grew as a mill village along the Winnipesaukee River and much of the stock dates to the 1800s, with the mixed-material plumbing that implies: cast-iron waste stacks, galvanized supply, copper patches, and the occasional length of something no one makes anymore. Water pressure complaints in old Tilton houses are usually the supply line, not the street.
The commercial corridor along Route 3 and Exit 20 is its own market — restaurants, retail, and lodging that need backflow devices, grease-line drain work, and repairs that can’t wait until Monday because a closed business is losing money by the hour.
Head away from the village — up Sanborn Road, out toward the Sanbornton line, or along the Silver Lake area — and you’re back on wells and septic, with the usual New Hampshire complement of pressure tanks, shallow lines, and unheated crawlspaces.
If you’re on Tilton town water, find your main shut-off and turn it fully closed and back open once a year. Old gate valves seize in the position they’ve sat in for a decade, and the moment you need it is the worst possible time to discover it won’t move.
Shutting down a seasonal house properly is not turning off a valve and opening the faucets. On a well system the pump is shut down, the pressure tank drained, the pump line relieved, and the whole distribution system blown out with compressed air at low, controlled pressure — because water left standing in a horizontal run is exactly where a pipe splits. Water heaters are drained. Every trap gets non-toxic RV antifreeze: sinks, tubs, showers, floor drains, and each toilet, with the tank and bowl emptied and treated.
Then the list nobody remembers. Whole-house filters and water softener tanks hold water and crack. Ice makers have a supply line and a reservoir. Dishwashers and washing machines hold water in the pump housing. Outdoor showers, dock hose bibs, boathouse sinks, wet bars, and irrigation zones all need to be drained separately. On a lake-draw system the foot valve and line have to come out of the water before ice-in.
We finish with a written record of what was drained, what was left charged, and where antifreeze went — so whoever opens the house in the spring, including a different person entirely, knows exactly what they’re walking into.
A standard Lakes Region camp winterization typically runs $175–$450 depending on the number of fixtures, whether it’s a well or town supply, and the extras (filters, softener, irrigation, boathouse). Spring startup runs similar. Booking both together is the way most owners do it.
Aim to be done by the end of October. The first hard freeze in the Lakes Region can arrive in early November and does not wait for your schedule. Waterfront and private-road properties should book earlier still, because access gets harder once the roads soften or the snow starts.
You can, and for a house you visit in winter it is often the better choice — but it is only as reliable as your power and your furnace. Most homeowner policies require a minimum interior temperature, commonly 55°F, or a shut-off water supply in a vacant home. If you leave heat on, add a low-temperature alarm so a heat failure does not become a burst pipe you find in April.
Water softeners and whole-house filter housings, ice maker lines, dishwasher and washing machine pump housings, and outdoor showers or dock hose bibs. All of them hold water, all of them crack, and none of them drain when you open the faucets. A written fixture list is the only reliable fix.
