Water Heater Repair Washington DC: $228 to $1,017 + Rebates

Repair prices are national; no publisher lists a DC-only water heater repair price. The Angi row is its DC price band for mid-range plumbing jobs.

Do this now: water heater leaking or no hot water

1. Smell gas near the heater? Do not relight the pilot. Leave, then call the gas utility or 911 from outside.
2. Leaking: close the cold water supply valve on top of the heater, then turn off the power at the breaker (electric) or set the gas control to off.
3. Water near outlets: shut the breaker off only from a dry spot.
4. No hot water but no leak: check the breaker on an electric heater, or whether the pilot is out on a gas one.
5. Take photos of any water damage before you mop, in case you file a claim.

Is it urgent? When a DC water heater needs help today

A gas smell or water spreading across the floor is urgent; a heater that is lukewarm can usually wait for a weekday visit. HomeGuide says a tank leaking from the bottom usually means the tank itself has failed and needs replacing, at $600 to $1,800, while leaks at fittings, the drain valve or the relief valve can often be fixed for $100 to $1,000.

In a DC winter, with 60.1 nights a year at or below freezing at Reagan National by NOAA's 1991 to 2020 normals, a dead heater in a cold basement is worth a same-day call. If water has already soaked the floor, see water damage restoration in Washington, DC.

DC water hardness: about 7 grains per gallon

DC tap water averages 126 ppm of total hardness, about 7 grains per gallon, with a range of 78 to 175 ppm, DC Water's 2025 water quality report shows. That mineral load settles in the bottom of a tank over time. Rheem lists rumbling or popping from sediment, rust-colored water and a rotten egg smell as signs a heater is going bad. A flush runs $75 to $250 and an anode rod $150 to $350 in HomeGuide's guide.

Do you need a permit to replace a water heater in DC?

Yes for gas: the DC Department of Buildings lists new and replacement gas appliances as work that needs a permit, and only licensed DC contractors for the trade may apply for trade permits. DOB's fee schedule has no separate water heater line; its instant permit is $26 per fixture or appliance, and Angi's DC guide says permit fees start at $26. A plain repair, like a new thermocouple, is a different job from a replacement, so ask which one you are paying for.

DCSEU rebates and no-cost heat pump water heaters

DCSEU pays $750 or $1,000 toward a heat pump water heater that replaces an electric one, and $1,200 or $1,600 when it replaces gas, depending on the unit's efficiency tier, for homes of four units or fewer installed after October 1, 2026. A $2,000 heavy-up rebate applies when you replace gas or oil equipment and need more electrical capacity. The rebates require a DOB permit. Income-qualified owners or renters in single-family homes can get a heat pump water heater at no cost through DCSEU's Affordable Home Electrification program. Prices are in water heater replacement cost and tankless water heater installation.

Repair or replace in an older DC home

The median DC home was built in 1958, the Census Bureau's 2020 to 2024 survey shows, so many basements have older venting, gas lines and shutoffs around the heater. A cheap part on a young heater is worth fixing; a tank leaking from the body is not. If a repair runs close to HomeGuide's $600 to $1,800 replacement range, ask the plumber to price both, with the DCSEU rebate taken off the heat pump option.

Questions to ask a DC water heater plumber

1. What is your DC license number, and will you pull the DOB permit if this becomes a replacement?
2. What is the service call fee? Angi says DC trip fees run toward the top of $100 to $300.
3. Is the leak from a fitting or valve, or from the tank itself?
4. If I replace it, what would a heat pump water heater cost after the DCSEU rebate?
5. Can I see proof of insurance and a written price before work starts?
