Repair, rehabilitation, and replacement solutions to restore well performance

Wells can degrade over time or fail due to casing corrosion, sedimentation, structural damage, or changing groundwater conditions. Cole Bros Well Drilling provides comprehensive well repair and replacement services throughout a 50-mile radius of Oceana County — restoring safe, reliable water access for rural homes, farms, and businesses. From targeted rehabilitation to full well replacement and abandonment, our team evaluates each situation and recommends the most practical, cost-effective solution.

Pump tests, video inspection, water sampling, and measurement of static and pumping water levels.

Recommendation & estimate

Clear options outlining repair, rehabilitation, or replacement, with detailed cost comparisons.

Execution

Skilled crews perform rehabilitation or replacement using appropriate equipment and materials, including grout sealing and sanitary well caps.

Post-service testing

Confirm restored yield, pump performance, and water quality.

Documentation & maintenance plan

Written report, warranty details, and recommended follow-up schedules.

Dealing with sediment and sand problems

Wells screened in unconsolidated materials may begin producing sand as formation materials migrate. We address this via redevelopment, setting pumps above unstable zones, or installing properly sized gravel packs and screens. When persistent sand production occurs, deepening or re-siting the well might be required.

Addressing microbial and chemical contamination

Biofouling can reduce yield and degrade water quality. We perform disinfecting treatments, shock chlorination, and in some cases recommend long-term treatment systems. For chemical contaminants, we provide testing and partner with water treatment specialists to install filtration, softening, or reverse-osmosis systems as needed.

Abandonment and sealing of old wells

Proper abandonment prevents cross-contamination between aquifers and protects groundwater. We follow state guidelines to remove or fill boreholes with approved materials and seal at the surface. This is critical for properties with unused or unsafe wells.

  • Emergency repairs for critical failures

    When a well or pump fails suddenly, our emergency team provides rapid diagnostics, temporary bypass pumping if needed, and immediate corrective plans to restore water. We prioritize critical repairs for farms and commercial customers who depend on consistent water flow.

  • Costs and planning

    Repair costs vary by approach: rehabilitation typically costs less than full replacement, but longevity and reliability differ. We provide transparent estimates explaining life-cycle expectations. For older wells, replacement may be the better long-term investment.

  • Preventative maintenance reduces the need for major repairs

    Regular maintenance — annual pressure tank checks, periodic water sampling, and pump current monitoring — detects early warning signs before substantial repairs are required. Cole Bros offers maintenance programs tailored to household, agricultural, and commercial needs.
