Hello,
Excuse my lack of knowledge but just wanted to get some advice...
We have had what appears to be some form of leak for the last couple of months in the ceiling/top of wall by our front door. It seems to occur even when it hasn't been raining.
The upstairs neighbor is a builder, but from what I've seen of his work it can often be a bit slap dash.
I noticed yesterday that there is a large hole where his bathroom pipes exit the house to the drain - see photo links

This hole is located in the area where the leak is so I'm wandering if this could be the cause.
Does this large hole look like a problem to you guys?
