Ask before you sign
- Will you pull the permit and schedule the inspection? Nearly every city here requires one.
- 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.
- Is there a floor drain or pan near the heater, so a leak doesn't flood the basement?
- 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.
Basement or attic install
Carrying tanks down narrow basement stairs adds time. Attic installs add even more.
+$100 to $375
Expansion tank
Needed on many homes with a pressure regulator. Protects the new tank from pressure spikes.
+$175 to $425
After-hours install
Same-day, night and weekend jobs carry a premium for on-call crews.
+$175 to $550
City permit
Required in nearly every Philadelphia 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.
+$200 to $525
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 Philadelphia?
Yes. In Philadelphia the plumber needs a city license and a permit from Licenses and Inspections. Suburban towns in Pennsylvania, New Jersey, Delaware and Maryland issue their own permits.
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. Pennsylvania has no statewide plumbing license, so suburbs license plumbers locally.
Does a basement install cost more?
A little. Tanks have to come down the stairs, and many older basements need a new vent connector or an expansion tank to meet current code. Attic installs cost more still.
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 Philadelphia area earn about 34% 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.
Who are the plumbers you connect me with?
