A new water heater by tonight.

The common sizes are on the truck. If yours is leaking at seven in the morning, you’ll have hot water by dinner, at the price on this page.

Replace it, or repair it?

If the tank itself is leaking from the bottom, it’s done. Steel tanks rust from the inside out and there’s no patch for it. If it’s a valve, a thermocouple, an element or a supply line, we fix it for a fraction of a new tank and tell you roughly how many years it has left.

Why so many Houston heaters are in the attic

Builders put them up there to save floor space. It works fine until the tank leaks over your ceiling. An attic install needs a proper drain pan piped outside, and it needs two people to carry fifty gallons of steel across the joists safely. That’s the $350.

Is tankless worth it here?

Sometimes. Houston groundwater is warm most of the year, so a tankless unit works less hard than it would up north. But most houses need a bigger gas line to run one, and the price difference takes a long time to pay back. We’ll check your meter and your line before we quote it, and we’ll tell you if a tank is the smarter buy.

Asked about water heaters.

How much does it cost to replace a water heater in Houston?

At Six-Ten a 40-gallon gas water heater is $1,895 installed, a 50-gallon gas is $2,095 and a 50-gallon electric is $1,795, including the permit and haul-away. Attic installs add $350. Whole-home gas tankless starts at $4,600.

Can you install it the same day?

Usually. The trucks carry 40- and 50-gallon tanks. Tankless and unusual sizes take a day or two.

How long does a water heater last?

Most tank water heaters last eight to twelve years. An annual flush helps, especially with Houston’s hard water.
