If you’re trying to find the best emergency plumber in San Antonio, speed matters just as much as skill. A burst pipe, overflowing drain, or backed-up sewer line can turn into major property damage fast, especially when it happens after normal business hours.
I pulled together local companies that stand out for emergency response, clear communication, and the ability to handle everything from simple leaks to bigger structural plumbing problems.
How much does hiring an emergency plumber cost in San Antonio?
Facing a late-night pipe burst will usually set you back $270 to $389, as most companies charge a base service fee plus elevated after-hours labor rates to deploy their crews.
| Service / Fee Type | Estimated Cost |
| Emergency Service Call / Diagnostic | $150 – $250 |
| Hourly Labor Rates (Emergency) | $100 – $350+ per hour |
| After-Hours Surcharge | $100 – $300 additional |
| Minor Repairs (e.g., pipe leak) | $150 – $250+ |
| Major Repairs (e.g., water heater) | $300 – $800+ |
1. Reliant Plumbing

Website: https://reliantplumbing.com/
Address: 1119 Fresno St
Contact: (210) 468-8020 | [email protected]
Hours: Available 24/7
Dealing with a sudden plumbing crisis is easier when a company uses flat-rate pricing upfront. That’s because you’re not guessing about surprise fees before the work even starts.
Reliant Plumbing covers a wide local service area and offers same-day dispatch for sudden blowouts. I like that they provide complimentary visual diagnostics, which gives you a clearer picture of the problem right away.
They handle specialized grinder pump repairs for lakeside properties. And their crews arrive with fully stocked trucks that can often clear drains or fix sinks on the first visit.
The tradeoff is that such a broad footprint can stretch the fleet thin. During a city-wide winter freeze, longer wait times are possible while teams move across multiple counties.
Customer Reviews
Provided exceptional service.
I had the pleasure of having Forrest as my plumber. He provided exceptional service. Forrest is very polite, punctual, and knowledgeable! He walked me through all his findings, found areas that required immediate attention, and provided estimates for immediate repairs and possible future items that would need attention when the time called for it. Reliant will be on speed dial. Thank you, Forrest! Give him a RAISE

I’m so satisfied.
This has to be the most awesome plumbing company that I have worked with and I have ran several businesses. Sam, the plumber was outstanding! Crystal at dispatch gave me the best customer service I have received in any business. Called in the morning, Sam came out about an hour later. Walked me thru all the steps. Gave me a quote and a discount and started the work asap and it was a big job. I’m so satisfied that I will put this company on our vendor list for all our clinics in the San Antonio, Austin and Dallas area.

2. Roadrunner Plumbing & Air

Website: https://www.callroadrunnerplumbing.com/
Address: 4706 College Park
Contact: (210) 763-2721 | (830) 203-6138
Hours: Available 24/7
Roadrunner Plumbing & Air makes a strong case for households that may need help with plumbing and heating, ventilation, and air conditioning (HVAC) issues at the same time.
When my rental property had a slab leak that affected the ductwork, I appreciated how carefully their team worked through the problem instead of making vague guesses.
Their technicians focus on the root cause, explain repair tiers clearly, and leave the job site impressively clean afterward. They also cover a broad footprint across Bexar and Guadalupe counties.
I like their educational approach and cross-trained team, which makes them a practical option for messier emergencies.
The downside is that heavy summer demand for air conditioning calls can slow dispatch for a more moderate plumbing issue.
Customer Reviews
I wouldn’t trust anybody else.
I have used Roadrunner Plumbing for over 10 years and always get prompt, professional service and repairs. They communicate clearly and deliver a high quality result for a fair price. I wouldn’t trust anybody else. Here’s some pictures of the pressure reducing valve they replaced. The plumber Jonathan Evans showed up on time and was done in about an hour. First class operation and plumbers.

3. 1-Tom-Plumber

Website: https://www.1tomplumber.com/
Address: 11549 Old Perrin Beitel Rd, #202
Contact: (726) 207-3922 | [email protected]
Hours: Available 24/7
1-Tom-Plumber stands out when fixing the pipe is only part of the job.
The company guarantees around-the-clock deployment, handles water damage restoration and structural drying, and brings specialized excavation equipment for collapsed main sewer lines.
That means fewer handoffs and a faster path from discovery to repair. They also do a good job explaining the failure by showing customers the broken components directly.
The main downside is cost. Because they run heavy machinery and rapid-response mitigation crews, the baseline trip fee can feel high if you only need help with a minor drip.
Still, combining excavation, repair, and cleanup into one call can save a lot of stress during a larger emergency.
Customer Reviews
Highly recommend 1-Tom Plumber!
Brandon with 1-Tom Plumber did an excellent job replacing a toilet and repairing a broken pipe and flange. He was courteous, professional, and worked quickly without cutting corners. Everything was explained clearly, and I felt confident in the quality of the work. Highly recommend 1-Tom Plumber!

The good experience and fast turnaround were a key priority.
The repair that needed to be done was very straightforward. The plumber knew what needed to be done and took care of it. I would like to point out my experience with the person who took my call; she understood the situation we were in and helped us get someone out quickly. The good experience and fast turnaround were a key priority for us because we have five kids and only two bathrooms. I’m very thankful for the immediate help.

4. 1st Call Plumbing & AC

Website: https://1stcallplumbingandac.com/
Address: 5511 Brewster St
Contact: (210) 446-0200
Hours: Monday-Sunday, 7:00 AM – 7:00 PM
Older neighborhoods often need plumbers who know how to deal with aging cast-iron lines. That’s where 1st Call Plumbing & AC really stands out.
They maintain dedicated dispatch numbers for central San Antonio and the northern corridor, which can help cut travel time when water is already going where it shouldn’t.
After I hired them for a sudden attic leak, I appreciated that the technician also checked my main water meter to rule out related issues before leaving.
They’re also a helpful team to consult before reaching out to renovation contractors for major structural updates. Their upfront quoting is fair and refreshingly free of hard-sell tactics.
The main drawback is that, as a dual-discipline shop, they may prioritize severe cooling failures over moderate plumbing issues during extreme summer weather.
Customer Reviews
I highly recommend this business.
Great service from Nate and Steve! When we had an emergency and our water was shut off we needed someone to come out fast. Not only did 1st Call answer on a Sunday they had someone out to us within 20 minutes. Nate and Steve had us back up and running quickly and they were very pleasant and professional. I highly recommend this business.

Thank you for the timely, and exceptional customer service!
I had a plumbing emergency early this morning. I called another company and they kept me waiting all day. I called 1st Call and they got to me within an hour of my call. Nate was very knowledgeable and efficient- he got my drains cleared and peace restored. Thank you for the timely, and exceptional customer service!

5. Smith & Sons Plumbing

Website: http://www.smithandsonstx.com/
Address: 2118 Mannix, Suite 102
Contact: (210) 338-0046 | [email protected]
Hours: Available 24/7
Smith & Sons Plumbing works well for homeowners who want a team that explains the problem clearly instead of rushing through the decision.
They invest in modern diagnostic equipment to speed up troubleshooting and on-site repairs. Plus, they back emergency work with a commitment to return if the first fix does not hold.
That accountability can be reassuring when you’re already dealing with water damage and stress.
They also have a strong grasp of local codes and hard water issues, which is especially useful for people already looking into water softener providers for longer-term home upgrades.
The tradeoff is capacity. Because the company runs with a smaller crew, it may have a harder time responding quickly during a city-wide surge in emergency calls.
Customer Reviews
I would recommend them to any of my friends and family.
I have used Smith & Sons on 3 occasions and have been impressed every time. Our plumber has always been punctual, friendly and courteous, providing us with quality work at a very reasonable price. They have always been available within a day of calling and have solved our plumbing issues on each visit. I would recommend them to any of my friends and family.
