- Licensed Texas plumbers
- Gas and electric, tank and tankless
- Same-day visits when the schedule allows
Installed price by size and fuel in DFW
These are typical ranges for the DFW market in 2026, not quotes. They combine the unit, ordinary labor, haul-away of the old tank and the small parts every code-compliant install needs. National cost guides set a wide net: Fixr puts a 50-gallon gas tank at $900 to $2,500 installed and an 80-gallon at up to $4,000, while NerdWallet gives a $600 to $2,500 range for a traditional tank and notes Home Depot averaging $1,950. North Texas lands in the middle to upper half of those spreads because permits and expansion tanks are routine here.
Gas costs more than electric to install, even though it is cheaper to run. A gas tank needs a flue, a gas connection with a shutoff and a sediment trap, and in many homes a correction to old venting. An electric tank needs a pan, a drain line and a dedicated circuit that is sized correctly.
| Size and fuel | Low | Typical | High |
|---|---|---|---|
| 40-gallon gas | $1,400 | $1,850 | $2,400 |
| 50-gallon gas | $1,600 | $2,100 | $2,800 |
| 75-gallon gas | $2,800 | $3,400 | $4,200 |
| 40-gallon electric | $1,100 | $1,500 | $2,000 |
| 50-gallon electric | $1,300 | $1,700 | $2,200 |
| 75-gallon electric | $2,000 | $2,600 | $3,400 |
Attic, garage or closet: where the heater sits changes the bill
Three places hold most heaters in North Texas homes. Slab-on-grade construction, common since the 1970s, pushed many tanks into garages and interior closets, and two-story houses from the Las Colinas and Plano boom years put them in attics. Each location triggers a different set of extras.
| Location | Typical extras | Added cost range |
|---|---|---|
| Interior closet or utility room | Vent reconnect, drain pan if above finished floor | $0 to $250 |
| Garage | Platform or stand for ignition sources (or a unit rated for flammable vapor), impact protection | $75 to $300 |
| Attic or second-floor closet | Watertight pan with a piped drain, vacuum relief valve, carrying the tank up and down, extra labor | $250 to $700 |
| Relocation to a new spot | New gas run, vent or water lines; separate permit scope | $600 to $2,500 or more |
Permit, haul-away and the code add-ons
Replacing a water heater needs a plumbing permit in most DFW cities, even for a like-for-like swap. Denton's published fee is $50 and Dallas lists a minimum permit fee of $100; the guides we opened show a national spread of $25 to $300. Check with your own city for the current figure, since it varies with scope. The licensed plumber doing the job normally pulls it, and the fee is passed through on your invoice.
Removal and disposal of the old tank usually costs $100 to $500 when it is itemized, according to Fixr, but many installers fold it into the labor line. These are the code items that most often get added to a bare-bones price, and they are why a quote that looks low can end up near the typical range.
| Item | Typical cost | Why it shows up |
|---|---|---|
| Plumbing permit | $50 to $150 | Required by most DFW cities for replacement |
| Thermal expansion tank | $150 to $400 installed | Closed systems with a check valve or pressure reducing valve |
| Drain pan with piped drain | $75 to $300 | Attics, upstairs closets, any spot over finished floors |
| New T&P discharge line | $50 to $200 | Old line is undersized, threaded, corroded or too short |
| Flue or vent repair | $500 to $1,100 for replacement venting | Power-vent costs more than direct-vent |
| Platform or stand in a garage | $75 to $200 | Ignition source near the floor |
| Haul-away of the old tank | $0 to $200 as a separate line | Often included in labor |
Big-box store install versus a plumber-led replacement
Retailers such as Home Depot and Lowe's advertise an all-in install price, and the unit price is hard to beat. The trade-off is scope: a retailer package usually covers a standard like-for-like swap and then bills for anything beyond it, such as venting corrections, pans, expansion tanks, gas fittings and attic access. A plumber-led replacement tends to start higher but folds the code items into the first number, and the plumber on site can adjust when the existing setup is not up to current code.
Neither route is wrong. A simple closet swap of a recent heater suits a packaged price. An attic, a failed vent or an older installation tends to favor a plumber who will fix what is found rather than write a change order.
| Factor | Big-box package | Plumber-led replacement |
|---|---|---|
| Advertised starting price | Lower; commonly under $1,800 | Higher; commonly $1,800 and up |
| Final price when the install is simple | Close to the advertised figure | Close to the quoted figure |
| Attic, vent repair or relocation | Extra charges added after the site visit | Included in the assessment |
| Permit handling | Varies by retailer and city | Pulled by the licensed plumber |
| Code items such as pan and expansion tank | Often billed as add-ons | Normally part of the job |
| Scheduling | Depends on the retailer's installer calendar | Same-day availability subject to schedule |
Ten-year cost of owning each type
The purchase price is only part of the cost. The table adds ten years of energy and routine care using stated assumptions: gas priced near $1.40 a therm delivered, and electricity near 15.4 cents a kWh (the Texas average that EIA data showed for the second quarter of 2026), and a family of three to four. Inch Calculator notes electric heating costs roughly $100 to $300 more per year than gas, which is consistent with the gap here.
Treat this as an illustration. A household that showers heavily or a house with a long pipe run to the kitchen will see bigger energy numbers on all three, and the order of the rows will not change.
| Type | Installed cost | Energy (10 years) | Maintenance (10 years) | Total |
|---|---|---|---|---|
| 50-gallon gas tank | $2,100 | $2,800 | $400 | $5,300 |
| 50-gallon electric tank | $1,700 | $5,400 | $400 | $7,500 |
| Gas tankless | $4,300 | $2,100 | $1,000 | $7,400 |
How a replacement price balloons
Four situations explain most of the replacement bills that run past the range. The first is a vent that no longer meets code, found when the old tank comes out and the flue shows rust or an improper slope. The second is a gas line that is undersized or lacks a shutoff and sediment trap. The third is water damage under the old tank that has to be dried and repaired before the new one goes in. The fourth is a switch from tank to tankless, which can add $150 to $2,500 over a like-for-like change according to NerdWallet's labor numbers.
Ask for the vent, the pan, the expansion tank and the permit to be named in the quote, so the total you approve is the total you pay. For the work itself, the details are on the installation page; for the cost of the other path, see the tankless cost guide.
Straight answers
What should a fair water heater replacement price look like in DFW?
In Dallas–Fort Worth in 2026, a fair installed price is about $1,400 to $2,800 for a 40 to 50 gallon gas tank and $1,300 to $2,200 for a 50-gallon electric. Prices above that usually reflect an attic location, vent repair or other code items, not just the heater.
How much does it cost to replace a 50-gallon water heater?
A 50-gallon gas tank typically costs $1,600 to $2,800 installed around DFW, with a common figure near $2,100. A 50-gallon electric typically costs $1,300 to $2,200. The wide spread comes from location, permit fees, venting and whether the old tank is hauled away as a separate charge.
Does a water heater replacement require a permit in Texas?
Most North Texas cities require a plumbing permit for a replacement, including Dallas and Denton, and fees run from about $50 to $150. State law does not set one rule for every city, so check with yours. A licensed plumber normally pulls the permit as part of the install.
Is it cheaper to install a gas or electric water heater?
Electric is cheaper to install, often by $300 to $500, because it needs no flue or gas connection. Gas is cheaper to run, commonly by $100 to $300 a year. Over ten years the gas model typically comes out ahead unless you have no gas service to the house.
Why do two quotes for the same water heater differ by $1,000?
The unit is rarely the cause. Quotes differ on whether the permit, expansion tank, pan, vent repair and haul-away are included, and on warranty length of the model chosen. Ask each bidder to itemize those lines so the totals can be compared fairly.
How long does a replacement take?
A standard tank swap in an accessible closet or garage typically takes two to four hours. An attic install, a vent correction or a gas line change can run into the afternoon. Permit inspection, where required, happens separately after the new unit is working.
