Common questions about water heater repair & replacement

What should a replacement heater cost around DC?
A basic 40-gallon swap generally lands somewhere between $1,850 and $2,900 fitted here, since permit fees and licensed labor in this market sit well above the national average, and the fuel type and venting move it further. Run the builder above for your own figure.
Fix it or start over?
Under eight years with a dead element or thermostat, repairing almost always wins. Once a tank is past ten and rusting through, replacing it is the cheaper move.
Who handles the permit?
We do. Fairfax County, Arlington, Alexandria and the District all require one for a heater replacement, and the paperwork is on our side of the job.
