I have an old house. I recently remodeled the kithen and downstairs bath which is connected to kitchen and under stairs. There is a pocket door in the bath that leads down another flight of stairs to the basement. The bath has a very noticable musty/drain type smell that is drifting into the kitchen, even when door is closed. The basement has a bit of a basement smell, but not as bad as the bath...so I don't think it's coming from there. I can open the door to the basement and smell it stronger in the bath than in the basement. I've "nosed" everywhere for the source. sink drain, around the bottom of toilet...can't find it.
I've seen foggers from homedepot...any one with any other suggestions? thankyou.
