How much does a water heater replacement cost in Houston?
A water heater replacement in Houston typically costs $1,720 for a 40-gallon electric tank, installed. The full range for that same straightforward swap is $1,340 to $2,300. That includes the unit and a normal replacement of the same fuel, in the same spot. It does not include a re-pipe, a new gas line, or a panel upgrade.
Electric, gas, heat pump, or tankless in Houston
The national starting point for that electric tank is $1,750 before local labor. Houston labor is 0.96 times a national crew. About 42% of the national price is labor, so the city changes the crew more than the box. Versus a crew priced at 1.00, that saves about $30. The same labor rate is applied to a 40-gallon gas tank, a heat-pump water heater, and a gas tankless. Those three are in the table. A heat pump costs more to install and usually less to run. A tankless costs more because the vent and the gas line often have to change.
What a fair bid looks like in Houston
Use the 1988 house of about 1,950 square feet as the example. A first-floor or garage closet swap, same fuel, existing vent and pan left in place, is the typical price of $1,720. The low price is that job with easy access and no code surprise. The high price is the same heater when the quote adds a drain pan, an expansion tank, a flue correction, or a second trip. If a quote says it is the easy swap and sits far above $2,300, ask which of those items is in it.
Garage tanks in this climate lose less standby heat than attic-adjacent closets, but a leak on a slab is expensive. A pan and a shutoff belong in the typical bid.
Running cost is not the install price
At 14.6¢ per kilowatt-hour, an electric water heater keeps charging you every month. A gas heater charges you mostly once, at install.

Installed costs start from published national ranges and scale the labor share. Rents are planning medians, not listings. Reviewed 2026-09-01.
If you rent in Houston
You almost never replace a water heater yourself without the owner. The price is the same either way. The decision is not. Use this range to read a landlord's quote. A claim that a standard tank is an emergency several times the high number is a reason to ask for the scope in writing, not a reason to hire a plumber in secret.
Before you call a plumber in Houston, match the quote to one row in the table. Typical for the electric tank is $1,720 at labor 0.96, on a 1988 home of about 1,950 square feet. Reviewed 2026-09-01. If the quote is a different fuel or a different location, it is a different job.
