Is builder in Chicago responible after 4 years, if his plumber did not follow code?
I purchsed a duplex condo in June 2006 with the master bed/bath in the basement level and just realized the tiled shower was leaking causing water damage and an airborne mold issue. I pulled a 12x12 tile off the shower bench, and noticed they did not use a water proof membrane. The bench was framed with a 2x12 which is rotting and water logged. The Bench is inside the shower and was not installed with a pitch, so water pools on the bench which I assume caused the leak into the framing of the adjacent wall. I have not verified they used a shower pan/membrance for the base of the shower yet, but I am not sure how to proceed. I've owned the condo for just over 4 years. Is the builder still responsible? Please help
