How these pages are written
Each service page starts with what you can safely check or do yourself, then explains what usually causes the problem, how a plumber diagnoses it and what the repair options are. Where a Laredo rule applies, such as the 2021 plumbing code the city adopted in 2024, the 2025 backflow ordinance or the drought plan’s five-day leak rule, the page says so and links the source.
We do not publish prices. Plumbing costs depend on access, materials, permits and the time of day, and any number we printed would be wrong for most houses. Each page lists what drives the cost instead, so you can compare estimates on equal terms.
Who does plumbing work in Texas
Plumbing work for others in Texas requires a license or registration from the Texas State Board of Plumbing Examiners. Plumbing companies operate under a Responsible Master Plumber, and the people doing the work may be master, journeyman or tradesman plumbers, apprentices working under supervision, or registered drain cleaners. Backflow assembly testers hold a separate license from the TCEQ, and lawn irrigation systems are generally installed by TCEQ-licensed irrigators.
You do not need to memorize the categories. Ask the company for its license number, check it on the board’s website, and ask who will actually do the work. The hiring guide covers the rest.
Permits inside city limits
Laredo’s Building Development Services department issues permits and inspects the work. Jobs that commonly need a plumbing permit include water heater replacement, gas piping, sewer repair or replacement, repiping, adding or moving fixtures, and new lawn irrigation systems. Simple repairs, like a flapper, a faucet cartridge or clearing a drain, generally do not. A permitted job is inspected, which gives you an independent check on work you usually cannot see once the wall is closed or the trench is filled.
Plumbing through the Laredo year
Plumbing problems in Laredo follow the weather more than people expect. A rough calendar helps you get ahead of them:
Spring
Sprinkler systems come back on after winter. It is a good time to walk each zone, fix broken heads before drought rules make them a violation, and check whether your backflow assembly is due for its three-year test. In 2026, one of the city’s twice-yearly free chlorine conversions began in late March, which can change how the water tastes for a few weeks.
Summer
Long stretches of heat mean the heaviest irrigation and pool use of the year, and the highest water bills. Drought stages are most likely to tighten now. A stuck sprinkler valve or a leaking pool fill line shows up fast on the meter.
Fall
A good season to flush the water heater, test shutoff valves and schedule work that needs walls or yards opened, before the holidays bring guests and extra loads on drains and the sewer line.
Winter
Hard freezes are rare but serious. Cover hose bibs and above-ground backflow assemblies when a freeze is forecast, open cabinet doors on outside walls, and know where the main shutoff is before the temperature drops.
Gas lines
In Texas, gas piping inside a home is plumbing work and requires a licensed plumber, and Laredo enforces the 2021 International Fuel Gas Code. If you smell gas, leave the house and call 911 and your gas utility from outside before calling a plumber. Do not switch lights or appliances on or off on the way out.
Repair or replace?
Many plumbing calls end with that question: fix the leak, the valve or the water heater, or replace it. A reasonable rule of thumb is to repair when the part that failed is small and the rest of the system is sound, and to replace when the material itself is wearing out, when repairs keep coming, or when a repair would cost a large share of a replacement. Ask the plumber to explain both options and what they expect from each over the next few years. Each service page has a section on choosing between them.
Before you call
- Stop the water if you can, and note which valve you closed
- Take a photo of the problem; it helps the plumber bring the right parts
- Have the water heater type and age handy if it is involved
- Know whether the house is on a slab or a raised floor
- If you rent, tell the landlord; many want to choose the plumber
Ask on the call whether the plumber handles gas work, backflow testing, water softeners and commercial jobs, since not every plumbing company does all of them. If it does not, it can usually tell you who does.
