Reply to comment by obsdifly in The new house I bought has some shims underneath the floor beams, between the concrete support & the beam, that are failing. Who would I call in Springfield? A framing company? by jgj570s

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?

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

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.

That seems like a lot.

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?

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)
