Well Casing Repair: Options & Solutions
📋 In This Guide
Signs of Casing Damage
Water Quality Changes
- Sand or sediment (new or increasing)
- Cloudiness
- Bacteria contamination
- Surface water taste/odor
- Water quality changes after rain
Well Performance
- Decreased yield
- Water level changes
- Pump wearing out faster
- Air in water
Visual Signs
- Rust at wellhead
- Cracks or holes visible
- Well cap damage
- Ground settling around well
Why It Matters
- Contamination risk (surface water entry)
- Pump damage from sand
- Well collapse possible
- Health hazard
What Causes Casing Damage
Corrosion
- Most common cause
- Steel casing rusts over time
- Acidic water accelerates
- Creates holes, weakness
Age
- Steel casing life: 30-50 years typical
- PVC: 50+ years
- Older wells more at risk
Ground Movement
- Earthquakes
- Land subsidence
- Heavy equipment near well
Poor Installation
- Inadequate grouting
- Wrong casing material
- Improper seal
Physical Damage
- Impact from above
- Pump installation damage
- Dropped tools
Repair Options
1. Camera Inspection First
- Essential before repair
- Shows damage location and extent
- Guides repair choice

2. Casing Liner
- New pipe installed inside old

3. Packers
- Inflatable seals at specific depths
- Isolate damaged sections
- Block surface water entry
- Good for specific problem areas
Cost: $1,000-$4,000
4. Grouting
- Cement or grout pumped around casing
- Fills voids and gaps
- Seals annular space
- Good for sealing issues
Cost: $1,000-$3,000
5. Patch Repair
- For localized damage
- Expandable patch placed over hole
- Less common
Cost: $1,000-$3,000
6. Deepening
- If damage is near bottom
- Drill deeper, add new casing
- May find more water too
Cost: $2,000-$10,000+
Repair vs New Well
Consider Repair When
- Damage is localized
- Well otherwise produces well
- Repair cost under $10,000
- Good well location
Consider New Well When
- Extensive damage
- Well is very old
- Low yield anyway
- Repair cost approaches new well
- Multiple problems
Cost Comparison
| Option | Cost Range |
|---|---|
| Minor repair (packer/grout) | $1,000-$4,000 |
| Casing liner | $3,000-$15,000 |
| New well | $15,000-$50,000 |
