old man stink in the house

Hey all.

We have always had (3 years now) an "old man stink" in our 1957 home. It's kind of a musty smell that I think originates from the crawl spaces that encompasses half of the footprint of the house. So this past year I removed all of the old poly and replaced it with new 6mil poly. I overlaped an taped it and pegged it 2 feet up on all of the walls. I also pluged the vents with poly and insulation. ...but the smell has not subsided.

Should I
1. "seal" the poly on the walls with maybe furing strips? right now the poly is just tacked.
2. should I insulated and/or poly the floor joists in the crawl space?
3. should I "seal" the duct work with say duct tape at the seems?
4. should I put in a dehumidifier?

Any other tips would help. Seems like I've read _tons_ and I'm on the right track. We're in central IL as far as geography. Also, soil in the crawls space is dry in some parts and slightly damp in others (under the poly), but no water. We have tiling all around the house, good roof water removal, and a well graded lot.

Thanks!
Nate

Are you sure that's what you're smelling? Did the previous owners have cats?

I don't think there were cats. Plus there is no carpet and only hardwood floors and tile. Seems more musty/stale than something with a scent.

what do you mean #4? The rh is 54% right now (and it's _extremely_ humid today)

If you're sure it's not from cats then I would insulate between the joists with R19 Kraft Faced, paper facing down. Then I would try a dehumidifier and an exhaust fan if possible.

54% is to close. Need to get it under 50%.
