What causes water damage in New Hampshire
Frozen pipes
Extended cold freezes pipes in older homes, seasonal camps and any house that loses heat.
Ice dams
Deep snow and heat loss through the roof back meltwater into ceilings and walls.
Snowmelt and river flooding
Rapid thaws and heavy rain raise the Merrimack and its tributaries and fill basements.
Homes and how they are built
Older capes, colonials and farmhouses with fieldstone foundations are common, along with lake camps and ski-area condos that sit empty for stretches. Many rural homes rely on private wells, and oil or propane heat that can run out.
When it happens
Freeze and ice dam season runs December through March. Flooding peaks with the spring thaw in March and April.

Licensing for contractors, plumbers and mold work differs by state and often by city. Ask any company for the licenses your state and local building department require, and check them before work starts.
In every state, homeowners insurance excludes rising floodwater, which needs a separate flood policy. See what homeowners insurance covers.

Questions from New Hampshire homeowners
What happens if my heating fuel runs out while I'm away?
The house freezes and pipes burst when they thaw. Use automatic fuel delivery and a low-temperature alarm, and have someone check the house.
Does insurance cover a freeze in a vacant home?
Policies often require that you kept the heat on or drained the plumbing. Read the freezing clause, especially for seasonal homes.
Can a fieldstone basement be kept dry?
It can be managed with drainage, a sump pump and a dehumidifier, but old stone foundations are rarely watertight.
