What is the correct foundation repair plan?
Pier placement is not an exact science, so it is not uncommon for reputable house leveling contractors to differ somewhat in their repair plans.

Except in cases of upheaval, a house has never been damaged by installing too many piers. Many Texas houses have lost market value because of inadequate underpinning.
