Signs Your Well Casing Is Damaged
Experiencing this problem right now? Call us for immediate assistance.
Your well casing is the protective barrier between your water supply and the surrounding soil. When it fails—through cracks, corrosion, or separation—contaminants can enter your well. Casing damage is serious and typically requires professional assessment and repair.
Common Causes
- Corrosion Over Time: Steel casings corrode, especially in acidic soil or water conditions. This is the most common cause of casing failure.
- Age: Casings have a finite lifespan. Wells over 40-50 years old are at higher risk regardless of material.
- Ground Movement: Earthquakes, soil settlement, or land subsidence can crack or shift casing.
- Improper Installation: Casings that weren't properly grouted or were damaged during installation fail earlier.
- Electrolysis: Electrical currents in the ground can accelerate corrosion in metal casings.
- Physical Damage: Impacts from equipment, dropped objects, or improper pump installation can crack casing.
Warning Signs to Watch For
- Water quality changes suddenly
- Sediment or debris in water
- E. coli or coliform bacteria detected
- Water looks cloudy after rain
- Well yield decreases
- Visible rust or holes at wellhead
- Water tastes or smells different
How to Fix This Problem
1. Get Professional Inspection
Video camera inspection can reveal the extent and location of damage. This guides repair options.
2. Water Quality Testing
Test for bacteria and other contaminants to understand the risk level and urgency.
3. Liner Installation
For some damage, a new liner can be installed inside the existing casing to restore integrity.
4. Casing Repair
Localized damage may be patchable. This is typically for newer damage in otherwise sound casing.
5. Well Replacement
Severely damaged casings, especially in older wells, often require drilling a new well.

Frequently Asked Questions
How long do well casings last?
Steel casings typically last 25-50 years depending on soil and water conditions. PVC casings can last longer but are less common in older wells.
Can you repair a cracked well casing?
Sometimes. Repairs are possible for localized damage. Extensive corrosion or multiple cracks usually mean the casing has reached the end of its useful life.
How much does it cost to replace well casing?
Casing repair or lining typically costs $3,000-10,000. If a new well is needed, costs range from $15,000-50,000+ depending on depth.
What happens if my well casing fails?
Groundwater contamination becomes likely. Surface water, bacteria, and other pollutants can enter the well. This is a health concern that requires prompt action.
