foundation repair

[Andy C]

I called 3 companys all said I need65-68 piers. But the prices are way different!! From 15k to 26k.
A. Doses this sound about right?
B. The major price difference is just concrete piers, concrete with wire,or concrete with steel rebar.
C. They all have lifetime warrantys and have been in biz. For over 30 year's. But only two of them pay into the state fund for a real warranty!
What do ya'll thank about it? I know some of ya'll have had it done and there's a few home builders in the bunch. is why I am asking cause it's alot of money either way.
