Allenstown at a glance

The U.S. Census Bureau estimates 4,882 Allenstown residents as of July 1, 2025 (4,709 in the 2020 census). The town’s Hazard Mitigation Plan Update 2021, prepared with the Central New Hampshire Regional Planning Commission and adopted by the Board of Selectmen on February 22, 2021, describes about 20.6 square miles (13,189 acres), of which 0.1 square mile is water, with Bear Brook State Park covering more than half the land area.

The plan says the Suncook River flows through Allenstown before joining the Merrimack, and that Downtown holds Town Hall, Fire, Police, Library, schools, manufactured-housing parks and businesses along US 3 (Main Street) toward Hooksett and across the river into Pembroke. NH 28 follows much of the Suncook. The Deerfield Road side is rural and remote around the State Park. Other named waters include Bear Brook, Catamount Brook, Little Bear Brook, Boat Meadow Brook, Pease Brook, and several ponds and marshes.

Carriers underwrite Allenstown houses around rebuild cost, roof age, heating and wiring, distance to a hydrant or fire station, and whether the lot sits near the Suncook floodplain or a washout-prone road.

Where you live in Allenstown changes the policy

• Downtown / Suncook Village and US 3. The plan’s denser population center sits along Main Street with municipal buildings, schools, businesses and manufactured-housing parks. Older village stock and park homes need accurate dwelling limits and water-backup options.
• Suncook River corridor and NH 28. The plan repeatedly maps floodplains of the Suncook River as the town’s primary riverine flood exposure. Houses near the river, crossings and low approaches need a FEMA map pull and a flood conversation before closing or renewal.
• Deerfield Road and Bear Brook State Park. The plan contrasts this rural side with Downtown: remote residences tucked into and around the park, with longer emergency and plow response. Tell us about wells, septic, outbuildings and how the house is reached in a storm.
• Near the Merrimack and Hooksett / Pembroke edges. The plan notes the Merrimack forms a small western boundary and that Suncook Village ties across the river into Pembroke. Border lots still need parcel-level flood and access details.

Flood coverage in Allenstown

The 2021 plan documents a severe flooding period from 2005 through 2012, including the Columbus Day Flood of 2005, the Mother’s Day Flood of May 2006, April 2007 storms and later events that damaged roads, bridges and homes. Its HIRA table scores inland and river flooding as present across town and along Suncook floodplains; high wind and severe winter weather score among the highest overall-risk natural hazards (8.0 each), while the flood history and NFIP record still drive how we review riverside homes.

Allenstown participates in the NFIP. The plan cites the Merrimack County Flood Insurance Study and current FIRMs effective April 19, 2010 (original maps April 2, 1979). As of September 2018 the plan reports 21 NFIP policies in force ($6.09 million of coverage), 96 paid losses since 1979 totaling about $2.11 million, and—as of April 2018—24 repetitive-loss properties (23 single-family and 1 multi-family). It also estimates about 150 parcels with buildings at least partly in special flood hazard areas, so most floodplain buildings still lack a flood policy.

A homeowners policy will not pay for the Suncook or Merrimack over its banks, or for surface water and road washouts outside a mapped zone. Flood is its own policy. Check your address on the FEMA Flood Map Service Center.

• 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.

See our flood insurance overview. 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.

Wind, winter and washouts

High wind events and severe winter weather each score an overall risk of 8.0 (high concern) in the plan’s HIRA. The photographic history and event tables include wind damage (including a October 2017 home destruction) and roadway washouts such as Deerfield Road in March 2020, plus Tropical Storm Irene and the 2011 Halloween snowstorm among regional declared events. Fallen trees, ice dams, frozen pipes and wind losses are generally homeowners claims, subject to your deductible and policy terms.

Winter, trees and wind in Allenstown

New Hampshire winters bring ice dams, frozen pipes and heavy snow loads, and storms bring down trees and limbs. 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 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, and Cincinnati and Chubb both write homes at any dwelling limit, so we quote both. Each carrier underwrites the specific house, so these are starting points, not promises.

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 or manufactured home in Allenstown, 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. On an older Downtown or Deerfield Road house, carriers will ask about the roof, heating, wiring, plumbing, well and septic.

Renters and tenants in Allenstown

If you rent in Allenstown, 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 Allenstown households also need auto insurance, and many add a personal umbrella. 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 Allenstown

• 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 house near the Suncook River floodplain or another mapped special flood hazard area
• A dwelling limit based on assessed value instead of rebuild cost on a Downtown or park home
• Well, septic or Deerfield Road access details 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 Allenstown

• 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 near the Suncook or a repetitive-loss neighborhood, keep any elevation certificate and prior flood quotes on your phone
• Know your plow and tree-crew contacts before the first nor’easter, especially on Deerfield Road

Buying a home in Allenstown

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. Ask whether any part of the lot is in a FEMA special flood hazard area, whether the seller has an elevation certificate, and whether the property has a flood-loss history. For a Deerfield Road or park home, get well, septic and access details into the insurance file before closing. We line up the homeowners binder, and a flood binder if you need one, so both are ready for your lender.

How a Allenstown 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.
