What your San Antonio neighbors have to say
EXCELLENT Based on 1016 reviews Posted on Diane McelroyTrustindex verifies that the original source of the review is Google. I am having a weird issue with intermittent dampness in my garage. Roger spent about 1.5 hours trying to locate the problem. He assured me it wasn’t a plumbing problem and told me not to worry about the service call. I will definitely use them next time I have a plumbing issue. Second 5 star experience with Plumbsmart. Paul serviced my water heater and installed a new toilet either a bidet, He showed up when promised and went right to work. I liked that he didn’t try to upsale me on anything and gave me honest opinions on work I was considering having done.Posted on Jared CrumedyTrustindex verifies that the original source of the review is Google. Service was amazing and quick. My shower knob was turning without stopping and the water wasn't coming out. Chris Garza assessed the problem and had it running within minutes. ✨10/10 stars✨.Posted on Chris HuggTrustindex verifies that the original source of the review is Google. Paul was great. I called first thing in the morning with a rather bad clog that had me extremely frustrated the night before. The scheduling team got everything set up, and Paul showed up right on time. He listened to me explain what was going, then got right to work. Took a bit of work, but got everything busted out and then ran a camera after to confirm things were clear and verify the condition of the pipes. Very professional and straightforward. Price was reasonable for what needed to be done as well which is always a bonus. Highly recommend PlumbSmart and especially Paul.Posted on Kat FloresTrustindex verifies that the original source of the review is Google. Our water heater stopped working. They were able to get someone out same day to troubleshoot and fixed the problem. Everyone I spoke with was very professional especially Joey (our tech). He really went above and beyond.Posted on gilbert u lopezTrustindex verifies that the original source of the review is Google. They continue to deliver peerless customer service!

It’s a pleasure to work with him.Posted on Ann HeindelTrustindex verifies that the original source of the review is Google. Because of a communication issue, Adam needed to come back for a follow up visit. He was true to his word. I had already paid for service and he came back as he said he would, a month later.

FAQs
What causes slow bathroom drains in San Antonio?
Soap scum, hair, and hard water minerals build up inside the pipe over time. Older homes can also have narrow or sagging drain lines. Our San Antonio bathroom plumbing repair team can clear the clog and check for deeper problems.
Do you repair leaking bathroom faucets and valves?
Yes. We fix dripping sink faucets, shower valves, and tub spouts by replacing worn cartridges, seals, or supply connections. A fast repair saves water and helps prevent cabinet or wall damage. PlumbSmart handles bathroom plumbing repair across San Antonio every day.
Can a running toilet increase my water bill?
Absolutely. A toilet that keeps running can waste gallons of water each hour, even if you don’t notice it. In many cases it is a simple fix, like a flapper or fill valve. We provide San Antonio bathroom plumbing repair to stop the waste.
When should I call for toilet repair in San Antonio?
Call if the toilet rocks, leaks at the base, refills constantly, clogs often, or won’t flush properly. These problems can damage flooring and lead to bigger drain issues. PlumbSmart’s San Antonio bathroom plumbing repair team can diagnose it and fix it safely.

San Antonio is growing fast, and many homes here deal with hard water, long hot summers, and the occasional winter freeze.
