Hi Guys,

I have a question, do any of you know what does the dark stain on the rim joist and floor joist (ends only) mean? They feel damp to the touch, but still solid when I hit it with my flash light. I see this around almost the entire perimeter of our 1350 SF house built in 1950's. Should I be concerned and replace them? :huh:


Thanks,
Juju

What is the siding on that house? And why does it go clear to the ground?

Oh, and the deck is wrong. Should be at least four inches below the door threshhold.

Hi md2lgyk,

I believe the exterior is made of stucco (am I answering your question?) and thanks for pointing out the deck, I will do some code research when we re-do our deck.

You are thinking East Coast code, with snow. The OP is in San Fran. The deck can only be a max. 1-3/4" below threshold.
I spec them even closer, about 3/4" for comfort's sake.

What happens when you stick an ice pick in the black area? Could be creosote. You used to be able to buy it in a can and brush it on.

We shaved a little piece off and it has regular light wood color within. So maybe you are right. It's hard to imagine someone would crawl alone the entire parameter to paint on every single rim and floor joist. :)
