Kevin,
Straightline charges our 'members' (Free Members too!) $225.00 pier. If they have to do a cement break out, i THINK that is is an extra $50. (which is reasonable, as they fill the hole back with concrete so you don't have to have it done!)
Rey Herrerra is the group rep, and he has been very honest with us, even when we didn't need piers in his estimation. He has also told us when he suspects a slab leak - and often he is right. (This happened last year on a rental we have owned for about 4 years!)
Another great feature is that their warranty work also stays with the house, so, no transfer upon sale is necessary.
Rey's number is: 817-770-3966
The office is also good to call (Number is: 817-979-7663) especially if you already know you want to schedule him. Just let them know you are with DFW REI CLUB so you will get our prices, and Rey will be the one to come out in 99% of the cases. (sometimes if he's unable, they have other guys to sub in)
Hope this helps!
