In case you missed this the first time, I am still advocating you do this or a similar attempt.

I am fairly well versed in carpentry but this is an area where I have had little experience. If it were a gable end, no problem but this wall has me stumped as far as the best and safest way to jack it up and do the repair.
the blocking method you show originally should work for you( every 16 or 24") . I would like to add - add filler blocks between your blocks to keep them from twisting, like band blocks. put the filler blocks directly above your temp beam and as close out to the foundation as possible. the screws you use to lock in your tie back blocks should suffice to keep twist from occurring but the filler blocks will without a doubt. make all your blocking the same size as the joists.

those blocks are relying on the plywood not being bad and helping take the load for a few inches. is your plywood sub floor bad at all?

Thanks Hand drive, I would have to agree with you. I will take your advice on this and thanks again. I'll also add a sister joist as de-nagorg suggested. Can't be too careful.

Thank you both for the suggestions.

I was thinking you could leave the temp blocking in as permanent if you can butt them over to the backside of the band you are replacing without interfering with the replacement. when ready just set the new band in tight against the blocking. keep in mind how the old band is pushing out some now and set temp blocks accordingly( back in so new band sits flush to foundation etc...) the temp blocks will sit some under the wall helping to hold it up while repairing. you could cut the blocking so it sits a hair above the foundation plate and then shim back down to new plate later after it is installed.

Thats what I was thinking hand drive, no reason to remove the blocking and I think it will be a plus since the rim is a single 2x.

OK.............got all the blocking in, 16" O/C. I located all the wall studs and placed the blocking so that it is inline with the wall studs. My blocking is under the bottom sill approx. 2". I found out today that the idiot that built this addition used 5/8 OSB as his subfloor. Really? Did you really save that much money by using 5/8 instead of 3/4? Did you? Freakin idiots!!!

Glad to hear back on this project. I appreciate being kept up to date.

Sounds like you are doing it right.

Me I would have used 3/4 plywood flooring.

That said I hope that your OSB, holds up for the long run, I have seen it deteriorate with the least amount of moisture getting on it.

Not as quick as particle board, but it still deteriorated to where I had to replace it for the need of strength reinforcement.

It was a spongy floor so my father had me lay down 7/16 osb and then luan over that before they replaced the flooring. That was a good move. One other interesting item was the rim joist, being 18' long, is in 3 pieces. A short 24" section, then a 14' section and then another 24" section at the other end. I have a nice seasoned treated 2x10x20 nice and straight to install as the new rim. Treated sill plate as well. I'll post pic's during the process.

Replacing Rim Joist and Plate.


Everything has been going according to the plan and rather well for this kind of project. I got the wall jacked up and supported, cut the nails that attatched the wall plate to the rim joist and the old rim joist just fell out. Cut the old plate up at the anchor bolts and removed it. I notched the new plate for the anchor bolts because its not possible to lift it over them. Cut the new rim joist to length ( one beautiful piece of treated 2x10) and slid it in behind the stone step and into place. It was a perfect fit. Secured with some saberdrive screws and lowered the jacks. That was it for day one.

Replacing Rim Joist and Plate.


DAY 2 : Today I tackle the plate and rim joist on the gable end. Moved the jacks into place and jacked the floor joists up about 1/2 an inch. Same process, cut the nails securing the wall place and subflooring, pulled nails that secured the rim joist into the end of the joists and she ,once again, just fell out. This side had more damage than anticipated but I was prepared. Installed the new plate in the same manner. I did have to "scab" new 2x10's to a few joists and ended up doing the same to each joist. There was a little damage to 4 of them but I decided it was worth the time to "scab" each joist. The joists are 18' so I scabbed an 8' 2x10 onto each one. Overkill but I'm assured that this job is not going to have to be done again in my lifetime. Once again, the rim joist fit nicely so I secured and lowered the jacks. Ran my screws in to secure the rim joist to the common joists and cleaned up. Next to come..........the finishing flashing and trim.

My apologies for not having more pics of the process. I get caught up in the work and can't seem to remember to stop and take pictures of the process.

It is not "overkill" to do it right. or to build for longevity.

Sometimes one must get it done now, so the pictures are not really necessary, just a nice touch.

looking good , keep it up.
