Deerfield at a glance

The U.S. Census Bureau estimates 4,989 Deerfield residents as of July 1, 2025 (4,850 in the April 2020 estimates base). The town’s Hazard Mitigation Plan Update 2019, prepared by the Southern New Hampshire Planning Commission and adopted by the Board of Selectmen on August 23, 2019, describes about 52.1 square miles, 50.8 of them land, bordered by Northwood, Nottingham, Raymond, Candia, Epsom and Allenstown.

The plan calls Deerfield rural, with its two major water bodies Pleasant Lake (495 acres, on the Northwood line) and Freese’s Pond. Other watercourses include the Lamprey River, Bean River, Beaver Creek, Nicholls Brook, Hartford Brook and the North Branch River. Routes 43 and 107 make it a commuting town for Concord and Manchester.

For insurance, that means single-family homes on well and septic, lake homes on Pleasant Lake, and wooded lots where wind, ice and fallen trees drive most claims.

Where you live in Deerfield changes the policy

• Routes 43 and 107. In the April 2007 flood, the plan says Route 107 and Route 43 were closed at the South Road split, Route 43 at the lower fairgrounds entrance, and Route 107 at the Epsom town line at Yeaton Farm. It also notes that a stray boat plugged the Route 107 culvert at Freese’s Pond, just north of the Route 43 junction, and flooded the road.
• The Lamprey River at Raymond Road. The plan says debris along the Lamprey River at the intersection of Raymond Road and Route 107 has flooded the road.
• Candia Road at Nicholls Brook. The plan pictures flooding there in April 2007, and says beaver dams occasionally block culverts and watercourses around town.
• Pleasant Lake and Freese’s Pond. Lakefront homes bring their own questions: shoreline, seasonal use, docks and boats.

Flood coverage in Deerfield

According to the plan, the most recent FEMA biennial report counted 75 residential structures in Deerfield’s special flood hazard areas, but the town had only 31 NFIP policies in force. Eleven claims had been filed, and one residential repetitive-loss property was insured under the NFIP.

The plan rates riverine flooding a moderate probability and debris-blocked culverts and ice jams a high probability, and says floods in Deerfield have historically come from snowmelt and heavy rain combined with debris-blocked crossings.

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 Deerfield plan

The plan rates hurricanes, hurricane-force winds, tornadoes, nor’easters, heavy snowstorms and ice storms as high-probability hazards. It says the most frequent wind problem in town is downed trees and the power lines they take with them. During the February 2010 windstorm, the town had many downed trees and a major power outage, and opened its overnight shelter for three nights.

For a homeowner, the takeaway is that most Deerfield losses start with trees and wind: roofs, siding, cars and outbuildings, followed by frozen pipes when the power is out. We review wind, water backup, flood and well coverage on every Deerfield homeowners quote.

Winter, trees and wind in Deerfield

The plan lists the historic December 2008 ice storm, the July 2008 tornado, the February 2010 windstorm and the October 2011 nor’easter among recent disasters. 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.

Lake homes on Pleasant Lake and newer homes on large wooded lots can cost much more to rebuild than their assessment, 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 Deerfield, 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 farmhouse, carriers will ask about the roof, heating, wiring, plumbing, well and septic, and about barns and other outbuildings.

Renters and tenants in Deerfield

If you rent in Deerfield, 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 Deerfield households also need auto insurance, and many add a personal umbrella. Deerfield households drive Routes 43 and 107 to work, the same roads the plan says closed in the 2007 flood, so a good auto policy and roadside coverage are worth a look. 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 Deerfield

• 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 near the Lamprey River, Nicholls Brook or Freese’s Pond
• A lake home on Pleasant Lake insured as seasonal after it became year-round
• Barns, outbuildings or a home business left off the application

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 Deerfield

• 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
• Have a plan for heat and water if a long outage hits; the town has opened its shelter for days at a time
• Keep trees near the house and driveway trimmed

Buying a home in Deerfield

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. Near the Lamprey River, a brook crossing or one of the lakes, ask for any elevation certificate and the seller’s flood history. For a lake home, 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 Deerfield 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 Deerfield, NH?

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

Does Deerfield flood?

In places. The town’s 2019 hazard mitigation plan describes the April 2007 flood closing parts of Routes 43 and 107, and lists debris flooding at Raymond Road and Route 107. It counted 75 homes in the floodplain but only 31 flood policies. 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.
