New Hampshire water damage
What causes water damage in New Hampshire
New Hampshire homes range from 19th-century mill-town housing in Manchester and Nashua to newer subdivisions in the southern tier. Cold winters mean frozen and burst pipes, ice dams on older, poorly insulated roofs, and basements that take on water during spring melt. Many homes outside the cities use private wells.
Burst pipes in cold snaps
Pipes in exterior walls, over garages and in crawl spaces are most at risk during multi-day subzero stretches.
Ice dams
Older capes and colonials with little attic insulation are prone to ice dams that push water into top-floor ceilings.
Wet basements
Spring thaw and heavy rain saturate soil around foundations, and many basements rely on a sump pump to stay dry.
Water damage risk by season in New Hampshire
New Hampshire's winter is its main risk season: frozen pipes, ice dams and heavy snow loads on roofs. Spring snowmelt and rain raise rivers and groundwater, flooding basements in March and April. Heavy summer rain has caused flash flooding in the hills and valleys, and tropical storm remnants occasionally bring flooding rain in late summer.
Licensing, permits and insurance in New Hampshire
Building permits are issued by each city or town. Private wells should be tested after flooding that reaches the wellhead. If you rent, report water damage to the landlord in writing and keep copies.

Storm, flood and fire disasters in New Hampshire since 2000
FEMA has issued 32 major disaster declarations in New Hampshire for weather and fire events since 2000, and New Hampshire policyholders filed 2,650 flood insurance claims through the National Flood Insurance Program in that time. Most homeowners policies exclude flooding from outside water, so those claims come from separate flood policies.

FAQ
New Hampshire water damage questions
How fast should a flooded New Hampshire basement be dried?
Start within 24 to 48 hours. Cold basements dry slowly, so dehumidifiers matter more than fans alone.
Should I test my well after a flood?
Yes. If floodwater reached the wellhead, disinfect and test the well before drinking the water.
How often does New Hampshire have federally declared storm, flood or fire disasters?
Since 2000, FEMA has issued 32 major disaster declarations in New Hampshire for weather and fire events: 23 severe storms, 3 floods, 2 hurricanes, 1 winter storm, 1 snowstorm, 1 coastal storm and 1 ice storm. Over the same period, policyholders filed 2,650 flood insurance claims through the National Flood Insurance Program.
