When foundation raising beats a foundation repair
If the trouble is one cracked corner or a short stretch of wall, fixing that section usually makes more sense than lifting the whole house. Raising earns its cost when the house needs a new or bigger foundation under all of it, or has to sit higher than it does now. I'll tell you which one I think your house needs and why, and you're welcome to check that against anybody else's take.
What shapes the cost of a foundation raising job
The biggest swing is what the bid includes. A lift-only bid covers getting the house up and leaves the utility disconnects, the new foundation and the reconnection for you to arrange, while a turnkey bid puts all of it in one number, so compare what each bid covers before you compare totals. After that, the size of the house, how high it goes and how much work the ground underneath needs move it up or down.
