Can you recommend a concrete lifting company?

Our front porch step has sunk and we need to get it lifted. Yes, we could have the whole thing ripped out and repoured, but this is the way we want to go. I've gotten one estimate from Raise-Rite and am trying to get another.

If anyone has used Raise-Rite I would appreciate some feedback on them. Any recommendations or advice to stay away from a specific company are appreciated.

Thanks!

Yes, I believe we used Raise-Rite a few years ago. They did a good job, and came in very reasonable with their quote.
