New Durham at a glance

The U.S. Census Bureau estimates 2,890 New Durham residents as of July 1, 2025 (2,697 in the April 2020 estimates base). The town’s 2022 Multi-Hazard Mitigation Plan Update, prepared with the Strafford Regional Planning Commission, describes a mostly rural town of 43.8 square miles (41.4 of land, 2.4 of water) in northern Strafford County, hilly, with elevations from 400 feet to 1,680 feet on the Brookfield line.

The plan lists Shaw’s Ponds, Merrymeeting Lake, Marsh Pond, Chalk Pond, March’s Pond, Downing Pond, Coldrain Pond and Club Pond, plus the headwaters of the Cocheco River, Hayes Brook and the Ela River. It notes that many of the town’s wetlands are also floodplains.

Development, the plan says, is mostly residential with scattered commercial and industrial uses, and the village area lies between the Merrymeeting River, Main Street, Old Bay Road, Tash Road and Route 11. For insurance, that means many lake and pond homes, some of them seasonal, plus houses on larger rural lots.

Where you live in New Durham changes the policy

• The pond shores. The plan names the southern shore of Downing’s Pond near the town center, the southeast and northwest shores of Chalk Pond, the northwest shore of March’s Pond and the southeastern shore of Shaw’s Pond as areas where homes are especially exposed to a 100-year flood.
• Merrymeeting Lake and the Merrymeeting River. The plan says most structures in the floodplain are homes along Merrymeeting Lake and part of the Merrymeeting River, and that the floodplain around the river, especially near the fish hatchery, is susceptible to flooding. The cover photo of the plan shows spring flooding over Merrymeeting Road along the marsh in 1984.
• The Ela River, Merrymeeting Brook and Hayes Brook. The plan sees significant flooding potential along Merrymeeting Brook, the Merrymeeting River and the Ela River, and a fairly wide floodplain along Hayes Brook in the southeast.
• Below the dams and along Kings Highway. Of the town’s 23 dams, the plan rates Merrymeeting Lake Dam, Jones Dam and Marches Pond Dam high hazard. A breach would send water down the Merrymeeting Brook valley toward Route 11 and the town center. It also says high water at the Ellis Hatch Dam in Brookfield would flood part of northwest New Durham, including three culverts on Kings Highway. No dam has failed in town in at least 20 years.

Flood coverage in New Durham

New Durham has been in the NFIP since June 27, 1977, and its flood map has not changed since May 17, 2005. The plan’s FEMA figures (January 2, 2022) showed 10 policies in force, 9 of them on single-family homes, with about $1.9 million of coverage, 2 paid losses and no repetitive loss claims.

The plan notes the town has worked with FEMA on compliance issues around the flood areas at Merrymeeting Lake. With thousands of acres of floodplain and homes on several ponds, 10 policies suggests most waterfront owners have no flood coverage.

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 hazards in the New Durham plan

The committee ranked severe thunderstorms and severe winter weather as the highest risks, flooding, dam failure, earthquake and landslide moderate, and wildfire and drought low. It notes steep slopes in the northern third of town above Merrymeeting Lake, where heavy rain can cause erosion.

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

Winter, trees and wind in New Durham

The plan says the January 1998 ice storm caused major tree damage and power outages lasting many days, especially on the ridge north of Merrymeeting Lake and around Birch Hill; the December 2008 ice storm hit southern and central New Hampshire hard; and the January 2009 and March 2010 storms brought downed trees, outages and road closures. For homeowners, that means ice dams, frozen pipes, snow loads and trees on roofs. 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.

Lakefront homes on Merrymeeting Lake and the ponds 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 New Durham, 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. Tell us if a camp sits empty all winter.

Renters and tenants in New Durham

If you rent in New Durham, 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 New Durham households also need auto insurance, and many add a personal umbrella. New Durham commuters rely on Route 11, and the plan’s dam inundation area reaches Route 11 and the town center, 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 New Durham

• 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 Merrymeeting Lake, a listed pond shore or the Merrymeeting River
• A seasonal camp that is now used year-round, or a year-round home left empty all winter
• Docks, boats and outbuildings missing from the policy

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 New Durham

• 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 Downing’s, Chalk, March’s or Shaw’s Pond or near the Merrymeeting River, keep sump-pump and elevation records handy
• Know how you will heat the house and keep pipes from freezing in a long power outage

Buying a home in New Durham

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 a lake or pond, or below one of the high-hazard dams, ask for any elevation certificate and the seller’s flood history. For a camp, confirm whether it is winterized and used year-round. We line up the homeowners binder, and a flood binder if you need one, so both are ready for your lender.

How a New Durham 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.

Frequently asked questions

Do you insure homes in New Durham, NH?

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

Does New Durham flood?

Along its ponds and rivers. The town’s 2022 hazard mitigation plan puts about 15% of the town in the 100-year floodplain and names the shores of Downing’s, Chalk, March’s and Shaw’s ponds and the Merrymeeting River near the fish hatchery as flood-prone. Check your address on the FEMA Flood Map Service Center.

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.

Who writes your NFIP flood policies?

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.
