For the past 3 months there's a rancid smell coming from my bathroom area like a dead rat or something. My bathroom area is clear and there's absolutely nothing in the vicinity that would make it my fault. The smell is not 24/7 but comes out occasionally.
There's a ventilator on top of the bathroom and my theory is that the smell is coming from there. Now how do I fix this or who do I call?
Thank you in advance!
