I am buying a 1920s tudor single family house in Westchester NY, and several larger patches on the northwall had very high humidity readings on the little humidity meter (70%-90%, in the red zone). Wall surface is stucco. The kitchen sink faces that wall and the 2nd floor bathroom drain should be right along that wall as well.
My question is: what's the likely reason? could it be a leaky pipe? Is opening the wall the only way to find out? Should I replace stucco with something else going forward? How about costs? Something like this, does it sound like a major major issue, or not that big a deal? I am signing the contract this week, so would apprecaite some input. Thanks.
