Local risks
What causes water damage in Dover
Original plumbing in older homes
37% of Dover's housing predates 1960. Pipes that old narrow with rust, joints weaken and drain lines crack, so a small drip behind plaster or under a floor can go unnoticed until stains or soft spots appear.
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.
Seasonal risks, licensing and FEMA history across the state are on the New Hampshire page.
