4 crawlspace jack screws + joist perimeter mount

[PandaBear]

Previously I had a thread about a crawl space beam "tilting" and ask how much / who can fix it.

Well today a foundation contractor came to take a look and said that the seller's home inspector isn't really finding what is going on. This section of the floor has 4 concrete pier block and column supporting girders and joist that is not attached to the concrete perimeter (hence the funny column supporting it off ground). The floor on top of it is sagging about 1/4" compare to the rest of the home. The joist should have been putting load on the girders (what I was calling "tilted beam") but it isn't; there's a 1/4 void between the joist and the girder.

The contractor recommended 4 jack screws (galvanized) to replace the wood posts supporting the girders, and mount the joist to the concrete perimeter via a retrofit mount bracket. Together it would be about $500 parts and $500 labor (3-4 hours) and they have to wait till another 1/2 day job so they don't lose one work day. They don't shim because it is not a permanent solution (has to keep shimming, the original shim job is now 1/4" void).

Any suggestion? Sounds fair? I found another company that has a minimum job size of $1400. Should a handy man shim it again? Will jack screwing in the future be DIY?

The 4 jack screws is a good solution in my opinion. We did this to my fathers home and served well for 40+ years. Placement of the jack screw support is crucial as is the base they will sit on. Once the system is in place it becomes a DIY option. Ed

That's a reasonable solution at a reasonable price.

It sounds good to me-certainly better than our 'shack in the woods' where 1929 tree stumps have actually served well for some of the posts.

and maybe use treated wood near the ground

Your contractor is right on. Sounds like a good price to me. I did a couple of repairs like that when I was doing home repair.
Looking at the pics, it looks like one of the floor Joists was replaced.

Go for it PandaBear. A common and correct fix.

Thanks for all the responses. I think I'll go ahead and have them do it, seems like it is not worth the DIY this time but future adjustment is.
