Water Leak Detection & Repair Services Near You
If your water bill jumps for no good reason, a leak could be the culprit. Leaks are common in San Antonio homes because pipes age, soil shifts, and temperature swings stress fittings. Even small leaks can waste a lot of water and cause rot or mold over time.
That’s why PlumbSmart responds quickly, pinpoints the leak, and gives you clear repair choices. You get honest pricing, clean work, and a fix that holds up. For most San Antonio leak calls, we can diagnose and begin repairs that day.
Common Signs of a Water Leak
Water leaks don’t always show up as a puddle. Many leaks start inside a wall, under a sink, or beneath the foundation, so the first clue is usually something that feels off. If you notice any of these signs in San Antonio, it’s time to call PlumbSmart.
Your water bill spikes without a clear reason
Musty smells that won’t go away
Damp drywall, bubbling paint, or staining
Random dripping sounds when no water is running
Low water pressure in one or more fixtures
Warm spots on floors or wet carpet areas
Your water meter moves when everything is off
Not sure if it’s a real leak or just a one time spike? We can inspect your plumbing system, fixtures, and main water line, then confirm what’s happening with targeted testing. If we find a leak, we’ll explain the repair and help you avoid future damage.
You deserve peace of mind at home. Our PlumbSmart team will fix the problem safely, cleanly, and the right way, so you can get back to your day.

We couldn’t be happier with the service and highly recommend him.Posted on Kathleen BallTrustindex verifies that the original source of the review is Google. Joey came by today to check on our fire place because we were concerned about a gas leak. From the start, this experience was great. It was easy to submit a booking request and the scheduler called a few hours afterward to set the time. They had an appointment available the very same day, which was great. I love how they sent info ahead regarding who the tech was. Joey called me before hand to say he could come by sooner if we wanted. He was professional, straight to the point, and put our minds at ease. I will definitely give these guys a call for any future plumbing issues we run into.Posted on David LinnTrustindex verifies that the original source of the review is Google. Our technician was very professional and talked me through everything he was going to do to fix our water softener. He rocked!Posted on Richard HouseTrustindex verifies that the original source of the review is Google. Outstanding service in every way. I got a next-day appointment, the technician (Paul) was on time and fixed the problem (stopped up drain) in less than 30 minutes. He was very professional and thorough in explaining and fixing the problem. He also explained various service options they provide for ongoing preventative maintenance.Posted on Ken RobertsonTrustindex verifies that the original source of the review is Google. Install a recirculating pump. Joey did outstanding work. Good price. Only problem is Plumsmart management sent Jorge the day before for the quote. They replaced Jorge with Joey which I am ok with. Just needed to be notified of the change. After the service was completed they sent me a review on Jorge, not Joey who did the work. No recipe either for work perform.Posted on Mary RamirezTrustindex verifies that the original source of the review is Google. Joey was very helpful and kind, he took the time to explain, was very professional. Thank you for your good service, and appreciate the discount on first time use, really came in handy. Thank you.

PlumbSmart — San Antonio
You can call us for assistance 24 hours, 7 days a week.
San Antonio is a great place to live, but local plumbing takes a beating. Hard water minerals build up inside pipes and fixtures, and hot summers followed by quick cold snaps can stress joints and valves. Add shifting soil and older neighborhoods, and it’s easy for small leaks to start and grow. That’s why quick water leak detection and repair in San Antonio matters.
PlumbSmart is local and we know the homes, the water, and the common leak patterns in San Antonio. From a dripping faucet to a slab leak, we show up ready to diagnose, explain, and fix it.
Need an upgrade while we’re there? We can replace old shutoff valves, update supply lines, install modern fixtures, and recommend simple water treatment options. Our goal is to make your plumbing more reliable and efficient, so you waste less water and avoid repeat leak repairs in San Antonio.
Plumbing problems are cheaper when you catch them early. With routine inspections and maintenance, PlumbSmart can spot corrosion, loose fittings, and pressure issues before they turn into a flooded cabinet or a damaged foundation. During a visit, we check visible plumbing, test key fixtures, look for hidden moisture, and review your water pressure. If something looks risky, we’ll tell you straight and help you plan the next step. No surprises, just solid guidance.
