Master plumber Chris Garza did an outstanding job finding our leak and repairing it immediately. He was professional, efficient, and the cost was very reasonable. 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.

FAQs
How long does water heater installation take?
Most water heater installation jobs in San Antonio take a few hours, depending on the location, connections, and whether upgrades are needed. We remove the old unit if required, install the new one safely, and test everything so you have reliable hot water.
What size water heater do I need at home?
Sizing depends on how many people live in the home and how much hot water you use at once. PlumbSmart helps San Antonio homeowners choose the right capacity so you don’t run out of hot water and don’t overpay for a unit that’s too large.
Should I install a tankless water heater in San Antonio?
Tankless water heaters can be great for endless hot water and energy savings, but they’re not best for every home. We’ll review your gas or electric setup, water quality, and usage so you can decide if tankless installation makes sense in San Antonio.
Do you remove and haul away the old heater?
Yes, we can remove and haul away your old water heater as part of the installation service. We’ll disconnect it safely, keep the work area clean, and make sure the new unit is installed correctly before we leave your San Antonio home.
Can hard water damage my new water heater?
Yes. San Antonio’s hard water can cause mineral buildup that reduces efficiency and shortens lifespan over time. We can recommend simple steps to protect your new water heater, like routine flushing, proper temperature settings, and water treatment options when needed.
