Water Damage in an Uptown Condo in Chicago, IL

This was caused by an old water heater that rusted through the bottom and started leaking out water.  The homeowner said that they didn't notice it until the floor started looking funny.  Initially it was hard to see the damage because the flooring is dark.  Homeowner had no idea that it was the water heater until the plumber who came to inspect showed him the rusted bottom.  Water damage has caused most of the flooring to cup, meaning that it is rippled.  The side edges of the planks swell up making a "U" shape.  Most of the flooring needed to be removed and the subfloor dried.
