Water Heater Repair/Replacement Cost Breakdown
A water heater repair cost will normally include:
- Supplies -- Small parts and supplies are usually included in the repair job's cost.
- Labor -- Your plumbing contractor may calculate an hourly fee (with a minimum) or a per-job charge for repair. If it is necessary to perform a new water heater installation to replace your old hot water heater, expect to pay extra for the labor involved in installing it, as well as the cost of the new water heater.
- Cleanup -- Haulage costs for your old water heater, if necessary, may add to the expense of this project.
Get the Most for Your Money
Make sure that your water heater repairs will conform to your local building code in terms of the venting system and other components. The easiest way to accomplish this is to have a local plumber near you either assist with the repair or installation, or have them perform the job themselves. Having them work on your water heater may be a bit pricier, but for more difficult jobs or replacements, it can end up being more economical as you can be assured that the project is done correctly.
If your water heater is already 8-10 years old when it breaks down, replace it. It's at the end of its useful lifespan anyway, and newer models -- especially tankless heaters -- are much more efficient.
