I needed my sewer line replaced and got five estimates, including two for trenchless pipe replacement. I ended up choosing the lower bid for digging up the yard, but if we had gone with the trenchless sewer repair option, this company would have been our choice. They had one of the best prices, and when Cameron came out the same day I requested a quote, he clearly explained how trenchless replacement works. He was very knowledgeable, patient, and answered all of our questions. The office also called us twice to follow up and make sure we did not have any other questions. We really appreciated the great customer service and the helpful guidance during the whole sewer line estimate process.

outstanding service! from beginning to end, san antonio due south plumbing handled everything in a professional and efficient way. malachi kept in touch with me the whole time, walking me through different repair options and prices. after our early morning call, scheduling was quick and easy. cameron arrived at my house within an hour to replace our tankless water heater. he was polite, worked quickly, and made sure to clean up all the mess when finished. in just a few hours, we had hot water running again! i'm really glad a neighbor told us about this company—they're now my first call for any plumbing issues or projects.

We had a serious plumbing issue when our water heater started leaking right after we had it serviced. We tried calling several places around San Antonio, but nobody had the right replacement parts in stock. We reached out to San Antonio Due South Plumbing late in the evening, and by the next morning, they called us back and let us know they had plenty of water heaters ready and could send someone out the very next day. Cameron and Malachi arrived early, got to work right away, and had our new water heater installed before lunchtime. They were both friendly, professional, and explained everything clearly. The whole process was quick and stress-free. We are very happy with the service and would definitely recommend them to anyone in need of a reliable plumber in San Antonio!

I had a fantastic experience with this plumbing company. Cameron was incredibly helpful throughout the process. As first-time homeowners, we had never dealt with a septic tank before, but Cameron explained everything clearly and made sure we understood what was happening when our plumbing system stopped draining. The service was fast and hassle-free, and it was great working with such a professional team. I was nervous about finding the right plumber for our septic and plumbing needs, but now I know exactly who to call in the future. Cameron pumped our septic tank, cleared a stubborn clog, and did it all at a fair and honest price. I highly recommend reaching out to this company for any plumbing or septic issues!

When we first moved into our house in San Antonio, we called San Antonio Due South Plumbing to help with our plumbing needs. They handled everything from cleaning out our tanks and grease trap to clearing out some tough roots from our main line. At the time, we were so busy settling in that we didn’t realize just how excellent their service was. Malachi and Cameron are the friendliest and most patient plumbers you could ask for. They took extra time to make sure we understood our whole plumbing system. Today, they carefully traced where all our sinks and showers were draining, which was something we never knew before—not everything went into the main tank! Now we know much more about how to take care of our system, especially our tricky grease trap that always seems to clog. Cameron showed us how we could add a clean out to keep things running smoothly. The team is always kind and helpful, and their prices are fair. You really can’t put a price on the peace of mind they give you.

I recently had an issue with a clogged toilet, and San Antonio Due South Plumbing solved the problem quickly and efficiently. Malachi, the plumber who came out, was very polite and made me feel comfortable about the situation. He fixed the issue fast and even gave me helpful tips for future plumbing needs. He explained my options and guided me through the whole process. The company also gave me a follow-up call the next day to make sure everything was still working fine. I was so impressed that I’m already scheduling another visit to have my kitchen faucet replaced. The office staff was also very friendly and easy to work with. I highly recommend this plumbing company!

i have used San Antonio Due South Plumbing for years because they always do solid plumbing work and really stand behind their repairs if anything comes up. most recently, i needed a shower valve cartridge swapped out. cameron handled it fast and left no mess at all. later on, i had to get the main valve changed in the same spot as the new cartridge. i asked for cameron again, and he and malachi managed to replace the valve without taking out any tile. they had to cut an access hole, but there was a fire block in the way. somehow, they still got the job done neat and tidy.

I had a great experience with this plumbing service. We couldn’t use our bathrooms or showers all day because of a stubborn clog. After waiting a long time for help, I finally called this company late at night. The dispatcher told me a plumber could come within a couple of hours, but Cameron actually arrived sooner than promised. He fixed the blockage quickly and got everything working again. The price was fair, too. I’ll definitely call them again for any plumbing problems. Cameron was friendly, patient, and understanding, even though it was late at night.

I called San Antonio Due South Plumbing early one morning because we had a strange leak inside the wall that we couldn't figure out ourselves. Malachi was busy, like most plumbers are, but said he could stop by later that afternoon to check it out. All the other companies we called said it would be next week before they could come. Malachi showed up that afternoon as promised and got right to work trying to find the problem. Since we were losing daylight, he couldn't pinpoint the exact source of the leak that day and thought it might be one of the pipes in the wall. Malachi returned the next day around lunchtime to keep investigating. By mid-afternoon, he discovered that our water heater needed to be replaced. We didn't expect to have hot water for the weekend since this was a last minute call, but Malachi immediately went out to pick up a new water heater that same evening. By that night, we had a brand new water heater installed and the leak was fixed. We really appreciated how Malachi fit us into his busy schedule, was thorough, knowledgeable, and made sure the job was done right—even if it meant staying late. We will definitely call again for any plumbing needs. If you want someone reliable, honest, and hardworking, this is the plumber for you!

Today started off rough when my tenants called to complain about a horrible smell coming from the laundry room drain in my rental house. It was really awful. I had used a plumbing service before to fix some issues with the dishwasher and kitchen pipes, so I reached out to them again. They were able to send someone out the same day. Cameron was great! The problem turned out to be tricky. My house is older, and I thought the plumbing was still in good shape, but I was wrong. Cameron and his assistant Malachi crawled under the house, even though the crawl space is really tight, and found that several old pipes from the kitchen, bathroom, and dishwasher had cracked and were leaking for quite a while under the house. There was water, waste, and a lot of build-up blocking the pipes, so hardly anything was draining properly. They replaced all the broken pipes and connectors, and while working, they also found a gas leak in one of the heating pipes. Cameron suggested I call the city about the gas leak. Malachi turned off the gas and capped the leaking pipes for safety. I let the tenants know, made some extra plans, and now everything is on track to be fixed. These plumbers do excellent work, and I highly recommend their service.

The plumbing service I received was outstanding, both in customer care and the plumber’s skills! I can’t say enough good things about my experience. I live in San Antonio, in an area where it’s usually hard to get someone out, but they answered my call right away and set up an appointment quickly. I needed help with my on-demand water heater—it needed a flush, some servicing, and the temperature adjusted. Malachi handled everything and made sure my system was working perfectly. He really went the extra mile and was a pleasure to work with. Cameron, who answered the phone, was one of the nicest and most professional people I’ve ever spoken to. As someone who knows how important first impressions are, I was really impressed by her helpfulness. My experience with this plumbing company was truly great!
