Ask before you sign
- Will you pull the city permit and schedule the inspection? It's required in Texas.
- What's your license number? I'd like to look it up.
- Is labor covered too, or only the unit? Ask how many years of labor warranty you get.
- Is haul-away of the old heater included?
- Are you replacing the gas connector and checking the vent? Most codes require a new flex connector.
- Does the price include a pan with a drain line to the outside, and a working shutoff?
- Should I add a FloodStop or auto shutoff valve? It's cheap insurance when the heater sits over or near finished space.
What moves the price
Two quotes for the same heater can be $1,500 apart. These six things explain most of the gap.
Attic access
Carrying a 150 lb tank up a pull-down ladder takes two people and more time.
+$250 to $675
Expansion tank
Needed on many homes with a pressure regulator. Protects the new tank from pressure spikes.
+$150 to $350
After-hours install
Same-day, night and weekend jobs carry a premium for on-call crews.
+$150 to $450
City permit
Required in nearly every Houston city. Already built into the ranges here.
Included
FloodStop valve
Shuts off the water if the pan senses a leak. Worth it over finished space.
+$175 to $425
Longer warranty
A 10 to 12 year tank is built heavier than a 6 year tank and priced that way.
+$100 to $700

Before you hire
Do I need a permit to replace a water heater in Houston?
Yes. Texas requires a licensed plumber and a permit for water heater replacement, even like-for-like. In the City of Houston and the surrounding cities, the plumber pulls the permit and an inspector signs off. A quote that skips the permit is cheaper for a reason.
How do I check a plumber's license?
Ask for their license number and look it up with the agency below. It takes about a minute.
Why do attic installs cost more?
Two people have to carry the old and new tanks through a pull-down ladder, and code requires a drain pan with a line to the outside, safe access and a solid platform. That adds labor and parts.
Should I repair or replace?
A leaking tank always means replacement. If the tank is over about 10 years old, replacing usually makes more sense than a big repair. Younger units with a bad thermostat, element or valve are often worth fixing.
Where do these prices come from?
They start from installed-cost data we verified in Dallas-Fort Worth and are adjusted for local labor: plumbers in the Houston area earn about 3% more than in Dallas-Fort Worth (U.S. Bureau of Labor Statistics, May 2025). Your plumber's price depends on the exact unit, access and code items found on site.
