Plumbing Installation and Replacement in Laredo, TX

Unlike a burst pipe, an installation can be planned. That's the best moment to compare prices, ask questions and choose the right equipment for your house.

Common installation jobs

Tankless water heaters

ENERGY STAR explains that a tankless heater has no storage tank: it heats water only when you open a tap, so it doesn't spend energy keeping a tank hot. Switching from a tank often means changes to the gas line or electrical service, venting and the water connections, so the price depends a lot on your house. For a standard tank replacement, Angi's national average is about $1,300; ask for a written estimate for the tankless option so you can compare. See also repair or replace your water heater?

Repiping

Repiping replaces old supply lines with new pipe throughout the house or in one section. People usually consider it after repeated leaks, a slab leak or very low pressure. Ask what material the plumber recommends and why, how they'll reach the pipes, and what wall or ceiling repairs are included. See leaks and slab leaks.

Toilets, faucets and shower valves

Replacing a toilet, a faucet or the valve inside a shower is common work. If the shower valve is inside the wall, ask whether the job includes opening and closing the wall, and who handles the tile.

Garbage disposals

Ask whether the price includes the unit, and whether your sink and electrical setup work with the new one.

Water softeners and filters

A plumber installs the unit and connects it to your water lines. Ask the installer what your water needs and what maintenance the system will require.

What to ask for in writing

• The full price: equipment, labor, materials, any permit and haul-away of old equipment.
• The Responsible Master Plumber's name and license number. Texas rules require them on plumbing proposals and invoices.
• The model and size of any water heater or fixture.
• The warranty on the equipment and on the labor.
• What's not included, such as drywall, tile or electrical work.

Before you hire

• Check each plumber's license in the state's public search. Texas law requires plumbing work to be done by licensed plumbers.
• Get at least two estimates for bigger jobs like repiping or a tankless conversion.
• Ask if the job needs a city permit. The plumber will tell you.
• Ask how long the water will be off and plan around it.

Installation FAQ

Is a tankless water heater worth it?

It depends on your house, how much hot water you use and what the conversion costs. Ask for written estimates for both a tank and a tankless unit and compare them over the years you plan to stay.

How do I know if I need to repipe?

Repeated leaks, a slab leak or low pressure all over the house are common reasons people ask. A plumber can inspect the pipes and tell you whether a repair or a repipe makes more sense.

Do I need a permit to replace a water heater?

Ask your plumber. They'll know what the City of Laredo requires for the job.
