I purchased my current home 3 years ago, the house is all of 18 years old. During installation of a new front deck, we discovered a fair amount of water damage to our Door box, and the wall adjacent to the box. We later learned the house had sustained storm damage, was "fixed", but apparently sealed up with wet wood; or so we're guessing (FYI - I had to replace the entire roof 3 months after I moved in, so if it were a bad roof, we've resolved that).

One of the joists between my first and second floors has rotted completely out at one end (about 2 feet of it). The subfloor above has also started to rot. My question is how much of the wood, the joist, do I need to cut back before splicing in a new piece?

What about treatment(s) for the remaing "good" wood near the damaged area?

If additional information is needed, let me know (just trying to keep this short).

Typically you would need to go another 2/3 so if the damage is 2Ft you would go 6Ft. If it was 3Ft you would go 9ft. The best of course is to cut off the rot & sister one at full length. That said the best fastener would be through bolts staggered, you want that to act as one member now.

Without seeing it it's almost impossible to guess, but you may want to look at the top plate as well at bearing.

Thanks for the response. Unfortunately I won't know just "how bad" this portion of my house is damaged, until I pull off the front siding and finish exposing the interior. The good news, I think, is that this is not on or near a load bearing wall, it's part of a "box" that juts off the front of the house between the 1st and second floors. From what I can see, by looking in the hole that I've 'made', it appears it's two joist, two that meet and attach, and the sub-floor that are affected. All the other wood members feel, look and appear solid.

Can you recommend any form of wood treatment I could use that may help "prevent" further rot? Will something like Thompson's Water Seal help with this?

Again, thank you for you input,
