DFW Well Service

Well Repair & Rehabilitation

Casing cracks, failed grout seals, and corroded screens don't fix themselves. We diagnose with a downhole camera and repair to TCEQ standards — without replacing the well.

Repair First, Replace Only If Necessary

A failing well casing or screen does not always mean you need a new well. Many structural issues — cracked casing, compromised grout seals, sediment infiltration through a corroded screen — can be corrected at a fraction of the cost of a new well, provided the borehole itself is sound.

Every well repair engagement starts with a downhole camera inspection. We don't guess at the failure point — we document it, give you a written assessment, and recommend the repair method that addresses the actual problem. For older steel-cased wells in North Texas, this step alone often reveals issues that explain years of water quality problems.

What We Repair

Casing repair & liner installation

Cracked or corroded steel or PVC casing relined to restore structural integrity and exclude surface water.

Grout seal restoration

Inadequate or failed annular seals repaired to TCEQ standards — the most common source of bacterial intrusion in older wells.

Screen replacement

Corroded or clogged well screens replaced to restore yield and stop sediment infiltration.

Well cap & sanitary seal

Damaged or missing well caps and vermin-proof sanitary seals replaced to prevent surface contamination.

Structural casing repair

Offset, damaged, or collapsed casing sections addressed — including repairs related to drought-induced ground movement.

Post-repair disinfection

Shock chlorination and flushing after all repair work, with guidance on follow-up bacteria testing.

How a Well Repair Service Call Works

  1. 1

    Camera inspection

    We lower a downhole camera to document the exact condition of the casing, screen, and borehole wall. This determines whether repair is viable and which repair method applies.

  2. 2

    Assessment and recommendation

    Based on the inspection we identify the failure point — cracked casing, failed grout seal, corroded screen — and recommend the lowest-cost repair that restores structural integrity and protects water quality.

  3. 3

    Repair or rehabilitation

    We perform the approved repair: grouting, liner installation, screen replacement, or casing patch. All work follows TCEQ standards for water well construction.

  4. 4

    Disinfection

    After any repair that opens the well, we shock-chlorinate and flush the system. This eliminates any bacteria introduced during the repair process.

  5. 5

    Documentation

    You receive a written record of the repair performed, depth, materials used, and our recommendation for follow-up water testing — important for property records and future service.

Frequently Asked Questions

How do I know if my well casing is damaged?
Common signs include sudden changes in water taste or smell, visible sediment or turbidity that was not present before, bacteria appearing in water tests after previously clean results, and — if you can see inside the well — visible cracks, corrosion, or holes in the steel or PVC casing. A camera inspection is the definitive diagnostic tool and is included in our well repair assessment.
What causes well casing failure?
In North Texas the most common causes are corrosion of older steel casings (20–40+ year wells), physical damage from shifting clay soils or drought-related ground movement, improper original installation (insufficient grouting, casing too short), and older perforated or slotted casings that allowed gravel or sand infiltration. Welded steel casings from the 1970s–80s are especially prone to corrosion at the weld seams.
Can a damaged well casing be repaired, or does it need to be replaced?
It depends on the location and extent of the damage. Cracks or holes in the upper casing section can often be repaired by grouting or by inserting a liner. Damage near the screen or below the water-bearing zone may require a liner or screen replacement. In some cases — particularly older steel wells with widespread corrosion — well rehabilitation or replacement is more cost-effective. We assess each well with a camera before recommending a repair approach.
What is well grouting and when is it required?
Grouting is the process of sealing the annular space between the well casing and the surrounding borehole with cement or bentonite to prevent surface water and contaminants from migrating down the outside of the casing and into the aquifer. Texas requires grouting to a minimum depth under TCEQ rules. Older wells often have inadequate grout seals — this is a common cause of bacterial contamination and is correctable without replacing the entire well.
How long does well repair take?
Minor repairs — replacing a well cap, correcting a grout seal near the surface, or installing a sanitary well seal — can be completed in a few hours. Screen replacement or liner installation in a deep well typically takes a full day. Camera inspection and assessment take 1–2 hours and are typically scheduled before committing to a repair approach.
Will I need to disinfect the well after repair?
Yes. Any time the well is opened for repair work, we perform a shock chlorination disinfection before we leave. We recommend following up with a bacteria test 5–7 days after the chlorine has fully flushed from the system to confirm the well is clean before returning it to regular use.

We diagnose before we recommend. Most well repair assessments are completed same-week across all 19 North Texas counties.
