Llano County sits on top of some of the oldest rock in Texas, and that makes well drilling here its own animal. If you are building on acreage near Llano or Kingsland, the granite under your feet decides how your well gets drilled and what it costs.
What well drilling costs in Llano County
$3,780 to $16,200 for a typical residential well (100 to 400 feet is common). Your real number depends on depth and ground conditions, which is why an on-site quote beats any calculator.
Questions to ask before you hire
- Are you licensed and bonded for water-well work in this state?
- What depth do most wells in this county hit water, and how do you price by foot?
- Do you handle the permit and the well-log filing, or do I?
- What pump and pressure-tank setup do you recommend for my acreage?
- What is your guarantee if the first hole comes up dry?
What to know about well drilling in Texas
The Llano Uplift is exposed granite and metamorphic rock, so many wells here produce from fractures rather than a clean sand layer. Output can vary sharply between two nearby tracts, and hard-rock drilling takes specialized rigs. Ask any driller how they handle fractured granite before you sign anything.
Texas licenses water-well drillers and pump installers at the state level, while building, septic, and land-use permits are handled county by county. Rural counties often have lighter permitting than metro areas, but septic (OSSF) permits and well-log filings are near universal. Confirm with your county before work starts. Always confirm current requirements with Texas Department of Licensing and Regulation and your county.

Common questions
Most residential wells run between $3,500 and $15,000, driven mostly by depth and ground conditions. Hard rock and deep water tables push the price up.
A straightforward residential well is usually drilled in one to three days once permits are in hand. Pump and pressure-tank hookup add a day.
Most states and counties require a permit and a filed well log. A licensed driller typically handles this, but confirm it in writing.
