Hi. I have seen a house I'd like to buy but on the 2 occasions I have viewed it there has been a strong smell of sewage as i have walked in, and it's in the kitchen too. It's a 1996 built 2 bed house converted into 3 bed with only one bathroom which is on the 1st floor. The 1st floor doesn't smell. The smell isn't coming from the kitchen sink. Any ideas what it is?
