How to level steps

I've got 2 steps from the front sidewalk to the deck. It's not bad enough to be unsafe - just could look better and not bad enough to replace. Suggestion on how to jack it up. Thanks.

there are people that can lift it with foam pumped under it or the people pump a concrete mixture under it, call your local concrete people for advice

 

neal, interesting post - didn't know about foam,,, we've mudjack'd w/cement/sand/water slurry but never foam - THANKS !

 

They came out last year and relevaled a 20ft side walk in ten minutes for $400 and came back and did it again when it settled a little for free. I was impressed they only drilled 3/4" holes in three places
