Why yes Tom in KY I am out there, WAY OUT THERE!! But seriously folks,....
Where to start... First what was the reason for the repairs.
Termites? Settling of piers? Soil bearing capacity or soil type like sand or clay.You live in Texas where there are not likely to be earthquakes but clay soil can expand to 4 times when wet. Do you live by a shore. I assume this is a one story home?
The reason you need to know all these diferent variables is I need to know about soil movement and high wind or hurricane areas as they change your spacing of piers and any new tie downs you may need to bring it up to current standards.
To get a real answer to your questions you need to get someone local to your area, like your building department or a licenced engineer or a competent ,licenced home inspector,preferably one from the www.ASHI.org
Tell us how you make out and mabey let the crew wait until monday to get the answers, don't be rushed and get it wrong.
It's to important to get a professional to look at it.
If you have to hire someone, take it of their end. They should have known how to fix this in the first place.
Good luck Jill!!
