Best Wood Foundation Repair in Arlington TX

We used Olshan in 2009 - because I wanted the best I could find to do my repairs.  They were more expensive, but I felt it was worth it.  Now, 6 years later, I have more foundation issues.  I've had 5 other companies out to look at my problem.  They all said - without exception - that Olshan put piers in the back of my house that were not needed.  They looked at the original drawings that Olshan did in 2009, and were puzzled as to why it was done.  Now, I have to have those piers removed or shortened because the house has heaved upward and caused additional damage to the structure.  I'm very disappointed - I thought I was getting the best company out there to do the work; now, I feel like I got scammed.  I don't think 5 other foundation companies would be wrong!
