An Independent Insurance Agency for All of New Hampshire

High-value · NH · Reviewed by Jon Merwin, licensed insurance agent · Published October 3, 2026 · Updated October 3, 2026

Looking for an insurance agency in New Hampshire that can handle more than a basic home and auto bundle? Portsmouth Atlantic Insurance is an independent agency. We’ve been in business since 2005 and we’re licensed in New Hampshire and nine other states. Because we don’t work for one insurance company, we can compare 30+ carriers for your home, cars, umbrella, flood and valuables. Our office is in Portsmouth, but our clients live all over the state, from Rye and New Castle to Bedford, Hanover and the shores of Lake Winnipesaukee. Most reviews happen by phone, video or email, so distance from Portsmouth doesn’t matter.

This page covers how coverage needs change across New Hampshire, what owners of larger or higher-value homes should ask, and how to check that any agent you’re considering is properly licensed.

Does it matter where in New Hampshire you live?

Yes. Every New Hampshire home gets nor’easters, ice dams and long heating seasons, but each region adds its own risks. Use the table below as a starting point before your review.

Region	Example towns	Risks worth a closer look	Ask your agent about
Seacoast	Portsmouth, Rye, New Castle, Hampton, Exeter	Storm surge, tidal and coastal flooding, wind on exposed lots, older homes in historic districts	Flood (NFIP and private), wind or hurricane deductibles, replacement cost for historic finishes
Merrimack Valley & southern tier	Bedford, Manchester, Amherst, Hollis, Windham	Larger suburban homes, finished basements, sump and sewer backup, teen drivers	Water backup limits, extended replacement cost, umbrella limits
Lakes Region	Wolfeboro and Lake Winnipesaukee towns	Seasonal homes left empty in winter, frozen pipes, docks, boats and guests	Vacancy or unoccupancy terms, water-shutoff devices, boat and umbrella coverage
Upper Valley & Monadnock	Hanover, Keene	River flooding, older farmhouses, wood stoves, outbuildings	Flood outside mapped zones, coverage for barns and other structures, heating system details
White Mountains & North Country	Second homes and ski-area properties	Long fire-response distances, heavy snow loads, rentals to visitors	How fire protection class affects your options, roof and snow-load questions, short-term rental terms

What should high-value homeowners in New Hampshire ask an insurance agent?

A standard homeowners policy is built for an average house. A custom build on the Seacoast, a renovated Bedford colonial or a lake house with a boathouse usually needs more than that. Bring these questions to any agent you’re considering:

• Is my dwelling limit based on the real cost to rebuild? Ask for a current replacement-cost estimate, and ask whether extended or guaranteed replacement cost is available on your home.
• How are jewelry, art, wine and collections handled? Standard policies cap certain categories. Scheduling items, or adding a separate valuables policy, can remove those caps.
• What happens if water backs up or a pipe freezes? Water backup coverage is often an add-on, and seasonal homes may have vacancy terms that change what’s covered.
• Is my liability protection in line with what I own? An umbrella policy sits above your home, auto and watercraft liability. It matters more if you have a pool, a dock, a boat or snowmobile trails crossing your land.
• Do I need flood coverage, and how much? Flood is excluded from standard homeowners policies, and NFIP building limits may not cover a high-value home on their own.
• Can one carrier write the whole household? Putting the home, second home, cars and umbrella with one high-value carrier can simplify claims and help avoid gaps between policies.

Which insurance companies can a New Hampshire independent agency compare?

We work with 30+ carriers. For high-value homes, the carriers we place most often include Chubb, Cincinnati, Hanover, Openly, National General and Andover. For flood, we offer NFIP policies (mainly through Selective) and private flood options from carriers such as Neptune, Aon Edge, Beyond Floods, Flow Flood, FloodFlow, CatCoverage and The Flood Insurance Agency.

There isn’t one “best” insurance company for every New Hampshire home. Which carrier fits depends on your home’s age, construction, location, claims history and the limits you need, and each carrier makes its own underwriting decisions. Our job is to show you what each option covers so you can compare them properly. See our full carrier list.

Do you need flood insurance in New Hampshire if you’re not on the coast?

Often, yes. Standard homeowners policies exclude flood, and flooding in New Hampshire isn’t limited to the coast. Snowmelt, heavy rain and rivers like the Merrimack and Connecticut can reach homes outside mapped flood zones. You can check your property on FEMA’s Flood Map Service Center. As of October 3, 2026, NFIP policies generally take 30 days to start (FloodSmart lists the exceptions), so don’t wait for a storm forecast to buy one.

How do you check that an insurance agent is licensed in New Hampshire?

The New Hampshire Insurance Department licenses insurance producers, and you can check any agent or agency for free through the NAIC State Based Systems license lookup (choose New Hampshire). The lookup shows whether the license is active and which lines of authority it covers. Before you choose an agent, also ask:

• Is the agency independent or captive? An independent agency can quote several carriers; a captive agent represents one company.
• Which carriers do you use for homes like mine?
• Who handles my account day to day, and who do I call when I have a claim?
• How often will you review my coverage as my home and assets change?

Frequently asked questions

Is homeowners insurance required by law in New Hampshire?

No. New Hampshire law does not require homeowners insurance, but most mortgage lenders require it for as long as you have a loan. Even with the mortgage paid off, it protects what is usually your largest asset and your personal liability.

What is the difference between an independent and a captive insurance agent?

A captive agent represents one insurance company. An independent agency like Portsmouth Atlantic Insurance works with many carriers, 30+ in our case, so we can compare coverage from several companies for the same home.

Can a Portsmouth agency insure my home in another part of New Hampshire?

Yes. We are licensed statewide and work with homeowners from the Seacoast to the Lakes Region, the Upper Valley and the North Country. Most reviews happen by phone, video or email.

Which insurance companies do you use for high-value homes in New Hampshire?

For high-value homes we most often work with Chubb, Cincinnati, Hanover, Openly, National General and Andover. Which carrier fits depends on the home, its location and the coverage you need.

Does homeowners insurance cover flooding in New Hampshire?

No. Standard homeowners policies exclude flood. Flood coverage comes from a separate NFIP or private flood policy, and NFIP policies generally have a 30-day waiting period before they take effect.

How do I check that an agent is licensed in New Hampshire?

Use the free NAIC State Based Systems license lookup and choose New Hampshire. It shows whether the license is active and which lines of insurance the agent is authorized to sell.
