Well acidizing to restore a slow or low-yield well

The most common sign is a gradual drop in water pressure or flow, where the well that used to keep up with the house now struggles, especially when several fixtures run at once. You may also notice the pump cycling more often or running longer to recover, and sometimes you will see white or rust-colored mineral scale on fixtures. In our limestone-heavy Hill Country geology, calcium carbonate buildup on the well screen and in the surrounding formation is a frequent culprit, and acidizing is often the right fix before you consider drilling a new well. If you are seeing these symptoms, give us a call at (830) 816-3232 and we can help you diagnose the cause.

We introduce a measured acid solution into the well to dissolve the calcium, iron, and other mineral deposits that have clogged the well screen, perforations, and the rock fissures that feed water into the well. The acid is allowed to soak and work for a period of time, then the well is thoroughly flushed and purged so no treatment chemical remains in your water. After flushing, we test the recovery and flow to confirm the well is producing better. Done correctly, this opens up the pathways that mineral scale had sealed off and restores much of the well's original yield.

In most cases, yes, and that is exactly why it is worth investigating first. Acidizing an existing well is typically a small fraction of the cost of drilling a brand new one. Pricing for acidizing depends on your well's depth, diameter, and the severity of the buildup, so we provide a quote after evaluating your specific well. Call us at (830) 816-3232 and we will give you an honest assessment of whether acidizing makes sense or whether replacement is the better long-term value.

Most residential acidizing jobs are completed in a single day, though the exact timeline depends on the soak time needed and how much flushing the well requires. We do not consider the job finished until the well has been fully purged and the water runs clear. We will tell you when your water is safe to use again, and for peace of mind we generally recommend a water test before you return to normal use. If your well also needs other service while we are on site, we will let you know how that affects the schedule.

Acidizing restores flow by removing the mineral scale that is there now, but it does not change the underlying water chemistry that caused the buildup in the first place. In areas with hard, mineral-rich groundwater like much of the Texas Hill Country, deposits can slowly reaccumulate over a span of years, so think of acidizing as restoration and periodic maintenance rather than a one-time permanent fix. How long the results last depends on your water and how heavily the well is used. We are happy to talk through realistic expectations for your situation when you call (830) 816-3232.
