Pier type chosen for the soil
Pressed concrete and steel are the two common options in this part of Texas and they suit different ground. The quote should say which and why.
Piers carry the weight of the house past the soil that keeps swelling and shrinking, down to ground that behaves the same all year. San Antonio Foundation Fix explains which pier type is being proposed for your house and why, before anything is installed.

Pier work is the heavier end of foundation repair. What follows is what a proper installation covers.
Pressed concrete and steel are the two common options in this part of Texas and they suit different ground. The quote should say which and why.
Piers go down until they meet ground that will carry the load. On the deep clay south and east of the city that is further down than it is on the north side.
Pier spacing and location come from the elevation readings and the structure above, not from a standard pattern applied to every house.
Pier count, depth approach, access requirements and any coverage on the work belong in the quote in writing, before you agree to it.
Ask what happens if a pier does not reach resistance at the expected depth, and whether that changes the price. Ask what the crew does about landscaping, patios and driveways in the way. Those answers separate a clear quote from a vague one.
The comparison page sets the two pier types side by side so you can follow the recommendation. Piers and leveling usually happen in the same visit, since one holds the other in place.
Piers alone do not stop soil from moving elsewhere around the house. Drainage and root barrier work addresses the cause, and a measured inspection decides whether piers are warranted at all.
That comes out of the elevation survey and the structure above, so it is not something anyone can answer over the phone. San Antonio Foundation Fix states the number and the locations in the written quote after measuring.
Deep enough to reach ground that carries the load, which varies a lot across Bexar County. Clay south and east of downtown runs much deeper than the limestone on the far north side. The quote states the approach for your address.
Coverage terms vary by contractor and by pier type, and they should be in writing on your quote before you sign. Ask what is covered, for how long and whether it moves with the house if you sell.
No honest contractor will promise that. Piers support the sections they are installed under. The soil around the rest of the house still responds to wet and dry seasons, which is why drainage and watering still matter afterwards.
