Get a bottle jack or almost any jack or two. Jack up just enough to take the weight off and replace yourself. It won't be that hard. If it was rocket science construction workers couldn't do it. Good luck construction worker

Can confirm I have very little DIY experience but have done this before.

I'm curious how they're failing? Floor sagging?

I'm a remodel contractor

It was caught in inspection. You can see that they are being crushed, and I think maybe that's what some of the bouncing of one of our floor sections is from.

Also some sheetrock cracks here & there. I want to replace with metal or composite shims.

Might make more sense in the long run to replace post with one that doesn't need shimmed?

That seems like a lot.

I mean a well rated handyman would be your best bet if you don't feel comfortable doing it yourself. For something that minor you'll still be charged hundreds by any contractor in town

Though if it is just shims, using a jack to lift the joist then sliding a new shim in is pretty simple

New construction we use steel plates for shims. Any decent handyman can do this for you.

They are just small, square steel shims that don’t crush. On another note if you have deflection or sagging in your floor the problem most likely isn’t the shims. Either the support posts our joists are settling or moving. That’s what needs to be shored up

I know that the shims were identified as a problem… So I kind of want to start there and see what happens. So you're saying it's not the entire pylon holding up the beam, but it's some sort of metal box or something? Do you have a link to it?

Do you know any in the Springfield area?

I’ve used hometown handyman several times and they’ve been great

Right on. I'll check them out. Thanks.

I mean you can use literally anything, more wood shims, these, steel.

Do you know how big the gap is? You might just call up a metal fab shop and ask how much it would be to cut you a 10-20 4"x4" squares of 20 gauge metal.

However no matter what shim what you go with, you must jack up the beam so you can fit the shims in, no way to get them in to do work without jacking up with beam slightly (1/16" maybe more)

This is good advice for all home diy. Very few things you can't do yourself with enough time and effort to learn.

Where can these shims be purchased? My new construction house has shims because they didn’t nail the subfloor correctly. We have major floor movement causing drywall cracks and floor popping.
