Repair or Replace Your Water Heater? How Laredo Homeowners Can Decide

Last updated: November 14, 2026

When the hot water stops, the first question is usually "fix it or buy a new one?" The answer depends on three things: where the problem is, how old the heater is and what the repair costs compared with a new unit.

Start with where the problem is

• The tank is leaking. Water coming from the tank body, not from a pipe or valve, points to the tank itself, and a new part won't seal it. Plan on a replacement.
• A connection or valve is leaking. Leaks at fittings, pipes or a valve are often repairable.
• No hot water, or not enough. This can be a part, the controls, the power or gas supply, or sediment in the tank. A plumber can test it and tell you which.
• Noises and rusty water. ENERGY STAR lists rumbling, rust in the water and reduced hot water among the signs that a heater needs attention. On an older heater, they often tip the decision toward replacing.

Then look at the age

ENERGY STAR's advice is that if your water heater is more than 10 years old, you should consider replacing it before it forces an emergency decision, because some heaters fail without warning.

To find the age, look at the label on the tank. The brand and serial number usually tell you when it was made, and some labels show the date directly. If you can't read it, the plumber can.

A simple way to decide

These are rules of thumb, not a quote. A licensed plumber who sees your heater can tell you what's worth fixing.

What a new water heater costs

Angi's national figures put installing or replacing a water heater at about $1,300 on average, with most jobs between $875 and $1,750. The price moves with the size of the tank, gas or electric, how hard it is to reach, and whether the venting, gas line or water connections need changes. Prices in Laredo can be different; the plumber confirms the price before starting.

Tank or tankless?

If you're replacing, it's a good moment to compare options. ENERGY STAR explains that a tankless heater has no storage tank and heats water only when it's needed, so it doesn't spend energy keeping a tank hot. Switching from a tank usually costs more up front, because the gas or electrical supply, venting and connections may need changes. Ask for written estimates for both so you can compare. See installation and replacement.

While you're at it: set it to 120°F

The U.S. Consumer Product Safety Commission recommends 120°F. Water at 150°F can cause third-degree burns in two seconds, and water at 140°F can burn in six. If you have young children or older adults at home, this matters.

Questions to ask the plumber

1. What exactly failed, and is the tank itself sound?
2. How old is the heater, and what do you recommend at that age?
3. What does the repair cost, and what would a replacement cost, both in writing?
4. What's included in a replacement: the unit, installation, any permit and haul-away of the old tank?
5. What warranty comes with the part, the new heater and the labor?
6. What's your license number? Look it up in the state's public search before work starts. Texas rules require plumbing proposals and invoices to show the Responsible Master Plumber's name and license number.

If it's leaking right now

Shut off the water at your main valve, keep water away from outlets and cords, and don't touch the relief valve or open the panels. If you smell gas, leave the house and call for help from outside. More in water heater problems and plumbing emergencies.
