Emergency plumbing in Houston: what after-hours help costs

The figures below are national ranges from Angi's September 2026 emergency plumber guide. Angi says emergency plumbers typically charge 1.5 to 3 times the standard rate.

Angi adds that many emergency plumbers charge a flat emergency service or trip fee of $150 to $300. HomeGuide's 2026 plumber cost guide gives similar signals: weekday nights at time and a half or more, and weekends, after hours and holidays at double or triple time.

HomeAdvisor also lists an emergency call-out fee of $100 to $300. All of these are national figures, not Houston prices.

Some situations cannot wait, and some can once you have taken the first steps yourself.

• Call tonight: a burst pipe you cannot isolate, sewage backing up inside with the cleanout dry, no water at all to the house, or a leaking water heater you cannot shut off.
• Call the utility or 911 first: a gas smell. CenterPoint Energy says to leave on foot and call its Greater Houston gas leak line at 713-659-2111 and 911 from a safe place. Sewage standing at the street cleanout is a city matter; Houston Public Works says to call 311.
• Can often wait for normal hours: a single clogged drain when other fixtures work, a dripping faucet, a running toilet, or a leak you have stopped by closing the fixture valve or the main.

Closing the main shutoff can turn a night call into a weekday appointment and save the emergency premium. Our emergency checklist covers the first ten minutes in detail.

• Keep the water off and open a faucet at the lowest point of the house to drain the lines.
• Move valuables and rugs away from the wet area and photograph the damage before cleanup, for your insurer.
• For a sewer backup, stop running water and check the cleanout near the street. Houston Public Works describes it as typically a white plastic pipe with a threaded or pull-off cap, sometimes under a metal cover. What you find there tells the plumber whether the blockage is likely in your line or the city's.
• For a gas smell, stay outside. CenterPoint Energy says not to use your cell phone near the leak, not to start a car and not to return to the area.
• For a frozen pipe, HomeAdvisor lists a typical flat fee of $100 for thawing, far less than repairing a pipe that splits. Keep the faucet open and never use an open flame.

1. Ask for the numbers on the phone. Trip or service fee, hourly rate, any minimum, and whether the clock starts when they leave or when they arrive.
2. Ask for the license number and the company's Responsible Master Plumber, and check them in the Texas plumbing license search while you wait. Texas law requires plumbers to carry their license while working, and TSBPE says service vehicles must display the company name and the Responsible Master Plumber's license number.
3. Approve the repair in writing before work beyond the emergency fix starts. Stopping the leak tonight and quoting the full repair tomorrow is reasonable.
4. Watch for pressure tactics. The Texas Attorney General warns not to let anyone rush you into signing a contract, never to sign one with blanks in it, and says scammers often demand full payment in advance.
5. Keep every receipt and photo for your insurer.
