What causes water damage in Allentown
Original plumbing in older homes
64% of Allentown'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.
Apartments and shared walls
Renters occupy about 58% of Allentown's homes. In multi-unit buildings, water from one unit travels through floors and shared walls, so report leaks to the landlord or association in writing right away.
Rowhome shared walls
Water from a neighbor's roof or plumbing can travel through party walls and shared basements.
