Holderness sits on Squam and Little Squam, which means high-value seasonal property, boat-access houses, and a shoreline where a burst pipe in an empty house is a very expensive problem. Nearly all of it is on private wells.
Holderness is Squam Lake country — the quieter, more private big lake, with a shoreline of family compounds and second homes reached by long wooded drives off Route 113 and Shepard Hill Road, plus genuine island and boat-access properties out on the water. Little Squam and the Squam River channel through the village add another cluster of waterfront buildings.
These are, on the whole, substantial buildings on private drilled wells, and many of them are seasonal or lightly used in winter. That combination — big house, complex plumbing, empty for months, own water system — is the highest-stakes winterization profile in the region. There’s often a well pump, a pressure tank, a filtration setup, three or four bathrooms, a laundry, a kitchen with an ice maker and a pot filler, an outdoor shower, a boathouse, and irrigation. Every one of those has to be handled deliberately.
Access shapes the work here as much as the plumbing does. Squam’s shoreline is deliberately undeveloped-looking, driveways are long and narrow, and some properties are only reachable by water. Getting a new water heater or pressure tank into a house like that is a logistics problem before it’s a plumbing problem, and we’d rather plan it properly with you than show up and improvise.
The village end of Holderness has a small year-round core — the school, the church, houses along the river — with the everyday plumbing work any town has.
On a large Squam-area house, get the winterization documented — a written list of what was drained, what was left charged, and where the antifreeze went. When a different person opens the house in May, that document is what prevents a very expensive mistake.
