What Increases Pool Light Repair Cost
- Water intrusion: corrosion increases repair scope
- Cord length: long conduit runs cost more to replace
- Niche damage: metal corrosion requires repair
- Electrical safety: GFCI and transformer issues add testing time
- Older pools: outdated fixtures are harder to repair
When Repair Is Enough vs When Replacement Is Required
Repair is usually enough if:
- The fixture housing is intact
- The issue is limited to gasket or wiring
- The light passes electrical safety testing
Replacement is usually required if:
- The fixture is corroded or leaking repeatedly
- The cord cannot be safely replaced
- The light is obsolete or non-code-compliant
Rule: If water has repeatedly entered the fixture, replacement is safer than repair.
Common Add-Ons During Pool Light Repair

| Transformer replacement | $200–$800 | Voltage or safety issues |
| Bonding or grounding repair | $200–$600 | Electrical safety compliance |
| Pool draining (if required) | $150–$500 | Severe niche or fixture issues |
