Kingston at a glance

The U.S. Census Bureau estimates 6,288 Kingston residents as of July 1, 2025 (6,194 in the April 2020 estimates base). The town received a state grant in 2023 to update its hazard mitigation plan; we could not find a posted copy, so this page relies on watershed studies and FEMA maps.

The Country Pond Watershed Management Plan (Rockingham Planning Commission and partners, 2021) says Kingston grew 117 percent from 1970 to 2019, and describes the Country Pond shore as densely developed with homes, campgrounds and youth camps. A 2024 Kingston Lake water quality memo for the town and lake association notes that Greenwood Pond flows into Kingston Lake by way of the Powwow River.

For insurance, Kingston is mostly single-family homes, many of them lake houses or former camps, with private wells and septic.

Where you live in Kingston changes the policy

• Country Pond. The plan says the old outlet dam in Newton is no longer used, so the pond’s level now follows Powwow Pond downstream, controlled by the state-owned Trickling Falls Dam. It also flags culverts on Wilders Grove Road just before the Kingston line, where Concannon Road serves about 20 homes on a Kingston peninsula, for an engineering review.
• Kingston Lake (Great Pond) and Greenwood Pond. Shorefront homes here can face high water, wave and ice damage to docks and walls, and runoff questions. A converted camp has to be insured as the year-round house it may now be.
• Along the Powwow River. The river links the town’s ponds. Homes in low ground along it should check the FEMA flood map rather than assume they are clear.
• Rural homes far from a hydrant or fire station. Outlying homes are rated differently by some carriers, so tell us how far the house is from the nearest hydrant and fire station.

Flood coverage in Kingston

Kingston’s ponds are connected through the Powwow River system, and the Country Pond plan notes that pond levels depend on dams downstream. Check your address on the FEMA flood map, and if the house is close to the water, compare NFIP and private flood before you need it.

Most lake homes carry no flood policy at all. Spring melt and heavy rain are when that gap shows up.

A homeowners policy will not pay for a river or pond over its banks, or for surface water. Flood is its own policy. Check your address on the FEMA Flood Map Service Center and ask us to compare NFIP and private flood.

• NFIP through Selective. We write National Flood Insurance Program policies through Selective, a Write Your Own carrier. The NFIP covers up to $250,000 for the building and $100,000 for contents. New policies generally have a 30-day waiting period (see FloodSmart), so buy before storm season, not during it.
• Private flood. When a home costs more than the NFIP building limit to rebuild, or you want coverage the NFIP leaves out, we compare Flow Flood, Neptune Flood, Beyond Floods, The Flood Insurance Agency, CatCoverage and Aon Edge. Each one decides address by address.
• Elevation certificates. If you have one, send it. If the house has been raised or has flood vents, it can make a real difference in how flood carriers rate it.

Water backup (sewer, drain or sump pump failure) is an add-on to homeowners; flood is separate. If your basement is finished, ask about both. See basement flooding coverage and our flood insurance overview.

Other risks for Kingston homes

Shoreline homes see erosion and ice pushing on walls and docks; the Country Pond plan notes many shorelines are armored with walls and riprap, and recommends natural “living shoreline” fixes. Docks, boats and guests on the water also raise liability questions, so line up your umbrella with your boat and home policies.

For a homeowner, most Kingston losses start with trees, wind and water: roofs, basements, wells and outbuildings. We review wind, water backup, flood and seasonal-occupancy terms on every Kingston homeowners quote.

Winter, trees and wind in Kingston

Like the rest of Rockingham County, Kingston gets nor’easters, heavy wet snow and ice storms that bring trees down on roofs and power lines. For homeowners, that means ice dams, frozen pipes and snow loads, and lake camps left empty in winter need special attention. These are generally homeowners claims, subject to your deductible and policy terms. A properly sized wind and all-perils deductible, and a roof in good shape, do more for most homeowners than any single add-on. Water damage from a burst pipe is usually covered when the home is heated and occupied; long vacancies can change that, so tell us if the house will sit empty.

Larger homes

Under about $2 million, most of our 40+ carriers are in play. In New Hampshire, Andover generally writes homeowners up to about $1.5 million, or closer to $1 million for homes far from a hydrant or fire station. Around $2 million to $3 million, Hanover is often a fit; above $3 million, Cincinnati; and at $5 million and up, Chubb. Each carrier underwrites the specific house, so these are starting points, not promises.

Renovated and newer homes on Kingston Lake and Country Pond can cost far more to rebuild than their assessment suggests, so we start with a replacement-cost estimate. See high-value home insurance in New Hampshire.

Condos, rentals and older homes

Your HO-6 condo policy covers what the association’s master policy does not. See condo insurance in New Hampshire. If you rent out a house in Kingston, you need a dwelling or landlord policy; for New Hampshire landlord and habitational placements we work with Vermont Mutual, Andover, Safety, Concord Group and Providence Mutual. For an older home or a lake camp, carriers will ask about the roof, heating, wiring, plumbing, well and septic, and whether the house is lived in year-round.

Renters and tenants in Kingston

If you rent in Kingston, your landlord’s policy covers the building, not your belongings or your liability. A renters policy covers both, plus extra living costs after a covered loss. We shop renters coverage across our carriers, and Progressive Home is one of them; we use Progressive Home for renters policies only. Landlords who own two- to four-family buildings can see landlord insurance.

Auto, umbrella and the rest of the household

Most Kingston households also need auto insurance, and many add a personal umbrella. Kingston commuters rely on Routes 125, 107 and 111, so a good auto policy and roadside coverage are worth a look. Ask about boat coverage too if you keep one on the lake. We quote them with the home so the liability limits line up, and we put rentals, second homes, boats and valuables under the same review. One agent, one renewal conversation.

Common coverage gaps we see in Kingston

• A dwelling limit based on the purchase price or assessed value instead of the cost to rebuild
• No water backup coverage on a house with a finished basement
• Personal property limits that have not kept up with what the household actually owns
• Liability limits on the home and auto that do not line up with an umbrella, or no umbrella at all
• No ordinance or law coverage on an older home that would need code upgrades after a loss
• No flood policy on a home on Kingston Lake, Country Pond, Greenwood Pond or the Powwow River
• A seasonal camp that is now used year-round, or a year-round home left empty all winter
• A boat or dock with no liability coverage lined up with the umbrella

Most of these are straightforward to fix once someone reads the declarations pages side by side, and that is the first thing we do in a review.

Before storm season in Kingston

• Know your hurricane or named-storm deductible in dollars, not just as a percentage
• Photograph or video each room so a contents claim is easier to document
• Keep your declarations pages, flood policy and any elevation certificate somewhere you can reach from your phone
• If you are thinking about flood coverage, buy it well ahead of a storm because of the waiting period
• If you live on the water, keep sump-pump and elevation records handy
• Pull in or secure docks and boats before a big storm

Buying a home in Kingston

Start the insurance conversation before you are under contract, not the week of closing. Send us the listing and the inspection report when you have it. The report answers most of what carriers ask: roof age, electrical panel, heating, plumbing and any water in the basement. On Kingston Lake, Country Pond or Greenwood Pond, ask for any elevation certificate, the seller’s flood history and the septic evaluation New Hampshire requires for many shorefront sales. We line up the homeowners binder, and a flood binder if you need one, so both are ready for your lender.

How a Kingston home quote works

• Tell us about the house: address, year built, square footage, roof age and updates to wiring, plumbing and heating.
• Send your current declarations page so we can compare like for like and point out limits that look short.
• We shop the carriers that fit and lay the options out side by side, with the differences in coverage, deductibles and storm terms, not just price.
• You choose, and we handle the switch, including your mortgage company and the effective date, so there is no gap.

Yes. We insure Kingston homes from our Portsmouth office at 601 Islington St, and by phone, email and online. Call (603) 431-4020.

Does Kingston flood?

Homes near Kingston Lake, Country Pond, Greenwood Pond and the Powwow River can. Pond levels in the system depend on dams downstream. Check your address on the FEMA Flood Map Service Center and ask us to compare NFIP and private flood.

Does homeowners insurance cover a flooded basement?

Not from flood. Water backup from sewers, drains or a sump pump is an add-on, and rising or surface water needs a flood policy.

We write NFIP policies through Selective, and we compare private flood from Flow Flood, Neptune Flood, Beyond Floods, The Flood Insurance Agency, CatCoverage and Aon Edge.

Do you charge fees?

No. We don’t charge fees on any policy we write, including homeowners, condo, renters, landlord, dwelling and auto.
