Closing a Center Harbor 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.
Center Harbor is one of the smallest towns in the region by population and one of the most concentrated by shoreline. The village sits at the head of the bay where Route 25 meets Route 25B, and most of the town’s built development runs along the water and the roads climbing away from it — Bean Road, College Road, and the neighborhoods toward the Moultonborough and Meredith lines.
Center Harbor is one of the communities connected to the state-run Winnipesaukee River Basin Program sewer system, which is unusual for a town this size and a genuine advantage for waterfront property. Water supply, though, is largely private — drilled wells and pressure tanks, with the maintenance responsibility that comes with them.
The seasonal share is high. A large portion of the housing stock is second homes and summer property, opened in May and closed in October, plus a smaller ring of year-round houses back from the water. That gives us a compressed spring and a compressed fall, and it’s why we ask Center Harbor owners to book shutdowns early rather than calling the week before Thanksgiving.
Because the town is small, the buildings tend to be personal — family places held a long time, with plumbing that reflects decades of do-it-yourself additions. A wet bar somebody plumbed in 1988, an outdoor shower off the back deck, a hose bib at the dock. Every one of those is a place water sits, and every one of them needs to be on the shutdown list by name.
Write down every water fixture on your Center Harbor property — including the dock hose bib, the outdoor shower, and the wet bar nobody uses — and keep the list with the shut-off. A written list is the only reliable way a shutdown doesn’t miss something.
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.
