Plumbing help in Laredo, TX

What to do first, by problem

Most plumbing damage happens in the minutes before anyone stops the water. These are the safe first steps for the calls plumbers get most often.

Water spraying or pouring

Close the fixture valve if the leak is at one sink, toilet or appliance. Otherwise close the main house shutoff, then open a low faucet to drain the lines. Stay away from wet outlets and cords. The emergency plumbing page has the full checklist.

Sewage coming up in a tub or floor drain

Stop using every fixture in the house, including the washer and dishwasher. Every flush adds to the backup. Do not pour chemical drain cleaners into a main line. See sewer lines.

Water around the water heater

Close the cold water valve at the top of the tank and turn the gas control to Off or switch off the breaker. A leak from the tank body cannot be repaired. See water heaters.

A bill that suddenly jumped

Do the 15-minute meter test with everything off. If the meter moves, close the house main and test again to learn whether the leak is inside or in the yard. Our guide to a high water bill in Laredo walks through the usual causes.

One slow drain

Try a plunger, clean the stopper or strainer, and stop there if it does not clear. Several slow drains at once point to the main line. See drain cleaning.

Backflow: the rule many Laredo homeowners missed

If your yard has an in-ground sprinkler system, it needs a backflow prevention assembly, and that assembly needs regular testing. Laredo rewrote its cross-connection rules in Ordinance 2025-O-103, effective July 18, 2025. Standard sprinkler assemblies are tested every three years by a state-certified tester registered with the city, who files the result online. Systems with a chemical injector need a reduced pressure assembly tested every year. Every outdoor faucet needs a hose bibb vacuum breaker.

The stakes became clear on May 22, 2026, when a failed backflow device at a single home let contaminated water back into the system and triggered a boil water notice for roughly half the city for four days. The backflow and irrigation page explains the rules in plain English.

What affects a plumbing bill

We do not publish prices, because they depend on the house and the problem. These factors matter more than anything else:

• After-hours calls. Nights, weekends and holidays often cost more at many companies.
• Access. Pipes under slabs, behind tile, in attics or in tight crawl spaces take longer to reach.
• Diagnosis. Leak detection and camera inspections may be priced separately from the repair.
• Materials. Water heaters, valves and pipe vary widely in price and quality.
• Permits and inspections. Larger jobs, like water heater replacement, repiping and sewer repair, typically need a city permit.
• Restoration. Patching drywall, tile or a driveway after the plumbing is fixed is often a separate cost.

Ask for a written, itemized estimate, and for larger jobs compare more than one. The hiring guide lists what a fair estimate should include.

Ask for the license

In Texas, plumbing companies operate under a Responsible Master Plumber licensed by the Texas State Board of Plumbing Examiners, and the people doing the work hold their own licenses or registrations. Ask for the license number and look it up on the board’s website; it takes a minute. Permits inside city limits go through Building Development Services. A plumber who suggests skipping a required permit is a reason to keep looking.

Homeowners may do plumbing in their own homestead without a license under Texas law. That covers replacing a flapper or a showerhead. It does not cover work on a rental property, and gas, venting and sewer work are good reasons to call a licensed plumber anyway.

When the city announces something about the water

Laredo has issued several boil water notices in recent years, including an 11-day citywide notice in October 2024 after E. coli was found in the system, and the utilities department switches to free chlorine twice a year as routine maintenance. Those are city matters; official notices always come from the City of Laredo. What happens inside your home afterward, such as flushing lines, replacing filters and servicing the water heater, is where a plumber can help. See water notices and drought rules.
