I have a house in the far north Dallas area that needs the foundation levelled; it's a slab foundation, brick house, approximately 1400 square feet. I have heard HORROR stories from others in the area who had theirfoundations repaired (yes, by reputable companies!), so I'm hesitant to proceed but need to do it so I can sell the house. Anyway, I'm wondering about ballpark figures for foundation repair in this area. I realize that there are variables, but what's a realistic high-low range?
