I believe they will be honest and tell you if you don't need repairs, we had ours checked about 6 months prior and it was fine then. Then it got really bad, cracking tile and sheetrock, doors not shutting right. So we used Olshan for our foundation repair about 4 months ago. They did a great job. We had two estimates and they both said pretty much the same thing, except Olshan wanted to put 1 more pier than the other but came down on their price to be comparable with the other estimate. Olshan's is fast also, the other company (I can't remember their name) would have taken about 3 months to do the work and Olshan's did it within a couple of weeks. Olshan has been around for a long time and has a life-time warranty on their work. Good luck.
