Closing a Plymouth 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.
Plymouth is served by the Plymouth Village Water & Sewer District, which covers the downtown, the Plymouth State University campus area, and the surrounding neighborhoods. That makes it one of the better-served towns in the region for public utilities — and one of the busiest for plumbing, because of what the buildings are used for.
A significant share of Plymouth’s housing is student rental property: older houses on Highland Street, Merrill Street, and the streets around the campus, cut into apartments, occupied by six people where a family of four used to live. Drains that would last decades in a single-family house clog every semester. Fixtures get used four times as hard. Landlords need a plumber who answers in August and January when the turnover happens and something always fails.
The downtown has its own commercial layer — restaurants on Main Street with grease-line and backflow requirements, and businesses that lose money every hour they’re closed.
Outside the district — up toward Texas Hill, out along the Baker River, toward Rumney and Campton — it goes back to wells and septic, with the usual rural New Hampshire freeze exposure. The Baker and Pemigewasset river valleys also mean a number of Plymouth properties sit low, and a house with a wet basement has plumbing consequences: pressure tanks, water heaters, and pumps that sit in water don’t last.
Plymouth also anchors our northern service area — it’s the practical edge of the Lakes Region, and we’re there regularly.
If you rent out a Plymouth property, replace the tenant-accessible shut-offs before you need them. Old multi-turn stops under sinks and toilets seize shut, and a tenant who can’t stop a running toilet at 2am becomes a flooded unit by 4am.
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.
