Water Heater Repair FAQs
- Is a leaking water heater an emergency?
- Treat it as one. Close the cold-water valve on top of the tank if you can reach it safely and call us — a failing tank can release its full volume.
- How long do water heaters last?
- Most residential tanks run roughly 10–12 years. Past that, repairs tend to be a bridge rather than a fix.
