Why Texas costs what it does
Texas is one of the cheapest states to test. Sandy soils across much of the state, plus lighter requirements, keep most perc tests in the $250–$600 range.
Much of Texas drains well, though the Blackland Prairie belt through the center is heavy clay that can raise costs and force engineered systems.
What still changes your price
Within Texas, the biggest swings come from the number and depth of test holes, whether your soil needs an engineered design, and which county holds the permit. Confirm your county’s exact requirements before booking. It’s the fastest way to avoid paying for testing you don’t need.
