Key facts
- New London has three lakes: Lake Sunapee on its western edge, Little Lake Sunapee to the north and Pleasant Lake to the east (Town of New London).
- Lake Sunapee covers about 4,155 acres, runs about 8.1 miles long, has 11 islands and three lighthouses maintained by the LSPA (Lake Sunapee Protective Association).
- Its shoreline is shared by New London, Sunapee and Newbury, and its outlet at Sunapee Harbor feeds the Sugar River.
- Many Sunapee-region homes are second homes used for both skiing and summer, so carriers ask about empty months.
- 1,000+ Google reviews and over 2,000 testimonials. A+ BBB.
New London homes: lake houses, village colonials and ski-country second homes
New London mixes a college town, a lake community and a ski-country retreat. Around Colby-Sawyer College and the town common are older colonials and capes. On the Lake Sunapee shore (including Georges Mills in neighboring Sunapee) and around Pleasant Lake are lake houses that range from expanded camps to large year-round homes. Up the hills are newer houses built for views of the lake and Mount Kearsarge, often used as second homes for skiing at Mount Sunapee and Ragged Mountain.
Lake Sunapee shore
Large year-round homes with docks and boathouses. Distance to water and flood zone shape the policy.
Hilltop view homes
Long driveways, wells and propane. Carriers ask about fire department distance and winter access.
Ski and summer houses
Two seasons of use and empty shoulder months. Monitoring and a caretaker help.
Village colonials
Older systems and finishes near the common. Replacement cost should reflect the craftsmanship.
Lake rules and what they mean for a rebuild
Lake Sunapee, Little Lake Sunapee and Pleasant Lake are public waters, so the state’s protected shoreland rules apply within 250 feet of the reference line, with a 50-foot waterfront buffer (NHDES Protected Shoreland FAQ). A shoreline rebuild may face permit conditions, a longer timeline and code upgrades. We look for extended replacement cost, ordinance or law coverage and additional living expense limits sized to a real Sunapee-region construction schedule.
Winter, wells and the empty-house problem
Most homes here rely on private wells, and many sit at the end of long, steep driveways. A pipe that freezes in an empty house in February can run for days before anyone notices. Carriers favor homes with low-temperature alerts, water-leak shutoff valves, generators and monitored alarms, and they want to know who checks the house. Snow load on large roofs and ice dams on complex rooflines are the other winter claims we see in this part of the state.

New London and Lake Sunapee home insurance FAQs
Who insures high-value homes in New London and around Lake Sunapee?
Portsmouth Atlantic Insurance compares 40+ carriers for New London, Sunapee and Newbury homes. For larger houses we quote Hanover (up to $2 million), Andover (New Hampshire homes up to $1.5 million), National General and Openly (up to $5 million in New Hampshire). The largest homes go to Cincinnati or Chubb.
Is insuring a Pleasant Lake or Little Lake Sunapee home different from Lake Sunapee?
The core questions are the same: rebuild cost, distance to water, docks and winter use. Smaller lakes can mean shallower frontage and older camps, while Lake Sunapee shore homes are more often large year-round houses. We set limits house by house. For shorefront homes in all three towns, see Lake Sunapee waterfront home insurance.
My Sunapee-area home is a ski-season and summer house. What do carriers ask?
Carriers ask which months the house is empty, whether the heat stays on, and whether there is low-temperature and leak monitoring. They also ask whether you rent it. Answering that up front helps us match the house to a carrier that writes seasonal or secondary homes.
Does homeowners insurance cover damage from high water on the lake?
No. Rising lake water is flood, which homeowners policies exclude. We can quote NFIP flood and private flood from Neptune, Beyond Floods, Flow Flood, Aon Edge, CatCoverage and The Flood Insurance Agency.
How do I insure a dock, boathouse or beach on Lake Sunapee?
Those are usually other structures on your home policy, with a limit based on a share of the dwelling limit. If they are worth more, we raise the limit or schedule them, and we check how each carrier handles ice damage.
Can you insure my Vermont or Upper Valley home too?
Yes. We are licensed in 10 states, including New Hampshire and Vermont, so one agency can handle the New London house, a Vermont ski place and the umbrella over both.
