Single Rim Joist Rotted - Support?


Hello,

I'm currently repairing my front deck after I found it was not flashed properly. I discovered that the single rim joist has rotted in several sections.
My concern with replacement is does the inside joists need to be supported. Based on the crawl space the joists are resting on the sill, but still concerned if extra support is needed before removing the rim joist.

I have attached outside and crawl space pictures. Any advice on this would be appreciated.

Agreed. I too fear no heights, nor falls. But that sudden stop scares the "willies" out of me.

It would be fairly easy to build a temporary support for your joists, from a few concrete blocks stacked, with a stringer board running the length needed to support the joists temporarily, that way you could work the rotted rim out from above and below without fear of collapsing the remainder of the deck.

No worries. Those joists ARE sitting on the sill and are not going DOWN. The main function of the rim joist or band joist along the sides of the house perpendicular to the floor joists is to keep the floor joists plumb and keep the from racking. In most cases the floor trusses are laid in place first and tacked to the sill with the rim following as the crew moves along and plumbs joists. Yes, the rim partially supports the floor above...to the tune of the thickness of the rim....but the rest is solidly sported by the trusses themselves. So you have a solid structure in place, replace the rotted rim, flash properly, and good to go. Ron

Took us 4 hours to complete the replacement, flashing and new ledger is installed. I wonder how much time it would have taken the pro's. Reason I did this as CHI the local company quoted me $2400 to replace the one board, no flashing etc just remove the rim joist. Seems like they are wanting a little to much per hour, I appreciate the help and extreme savings.

Thank you

Don't think OSHA would approve. We were putting ridge cap on because builder was from out of state and wouldn't come back to finish and his son went out and took the pic. It sat for months with no ridge cap. Just wanted to get it done. Thing is we have both taken OSHA and MSHA courses.

At least when the guy on the metal roof starts sliding he has something to grab on to.
