Local risks
What causes water damage in Hempstead
Original plumbing in older homes
56% of Hempstead'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.
Leaks between units
About 54% of occupied homes in Hempstead are rented, and many are apartments or condos. A leak in one unit often reaches the units below, so landlords, associations and each tenant's insurer are involved.
Flash flooding
Intense rain has overwhelmed storm drains in recent years, sending water into basement apartments and finished lower levels.
Seasonal risks, licensing and FEMA history across the state are on the New York page.
