Should I repair or replace my water heater?

Tank water heaters are reliable for the first 8 to 12 years. If maintained regularly, they can be even more reliable! However, at some point in a water heater's lifespan, repairs begin to accumulate. Other issues may also emerge (like being excessively loud or causing very high energy bills—no thanks!). All these problems tend to worsen over time, so a replacement eventually becomes a wise choice.

Consider replacing your water heater if:

  • Your water heater is more than 10 years old.
  • You run out of hot water faster than you used to (and your hot water usage hasn't changed).
  • Your water heater energy costs increase yearly, but you haven't changed your hot water usage.
  • Your water heater is showing signs of rust and corrosion.

Water heater repair cost factors:

The part that needs to be replaced

The cost of repairing a water heater may rise if a more intricate part is damaged or multiple parts require replacement. Our plumbers will always inform you about the part(s) that need repair and discuss various repair options, leaving the final decision to you.

Accessibility of the water heater/pipes

If your water heater is in a difficult-to-access area, such as a small closet, the repair may take longer, leading to slightly increased labor costs. Additional labor may be required to clear a path to the water heater.

Whether your warranty is valid

A valid warranty can lead to significant savings on your repair. Typically, manufacturer warranties for water heaters cover replacement parts for 1 to 5 years from installation. A labor warranty may also be included if your water heater was installed within the last year or so.
