Best Plumbing Services in San Antonio, TX

I love how respectful they are and how professional they are as well. Highly recommend this company!! Thank You so much for coming out and fixing my issue in my bathroom tub

This Company is Terrific!  We first called them in the middle of the night (2am!)...Dixie picked up the phone & said she would get someone out to our house right away, AND SURE ENOUGH she sent someone who stopped the water flowing onto our bedroom carpet!!!  We also called when our hot water heater leaked & flooded our garage.  Again, Texas Plumbing Diagnostics took care of our problem in a jiffy.  Competent, Professional Plumbers You Can Depend Upon!!!  Thanks, Dixie, YOU are our GO-TO-Plumbing Service ALWAYS!

Honest and trustworthy.  He is extremely knowledgeable and very honest on cost.  Will not overcharge you and will explain the whole process prior to just doing the work.  Will be using him again.

Our water heater went out and we needed a replacement fast. Gabe was the first to reach out and offered to replace our unit the same day. His quote was very affordable compared with others that we received. His work is high quality and he made adjustments so if there is a need in the future repairs will be easier to perform. I highly recommend Gabe, and we now have a new plumber!

You can TRUST this company!  Very competitive quote which includes everything--you won't be upcharged when they are installing your Hot Water Heater or the like.  Top notch parts.  Friendly, clean, careful, etc.

Hands down, these guys are the most honest and do the best work I've experienced in town! They have been to my 1938 house several times now for various reasons and have always done outstanding work! They have even taken on a few little additional tasks I throw at them and aways say we'll take care of it, no problem!! I would recommend this family business to my mother, grandmother, friend, or anyone looking for an honest-to-goodness great plumber! Now, if only they did electrical! AMAZING!

I had a slab leak I attempted to fix myself, worked for about a week and failed.  Kunz plumbers came, they saw, they fixed - within a day.  They, unlike me, know what they're doing and are reasonably priced.

Our AC system went out late on a Saturday night, so we called Woods Comfort System early Sunday morning. They were able to fit us in quickly and were able to repair.  Our technician, Virgle Wiley was professional and knowledgeable and able to diagnose our issue (bad motor) quickly.  Thank you for getting us back up and running during a very HOT day.

Went here yesterday in desperation after Home Depot and Lowe's didn't have the right size of shower drain cover I was looking to replace. This tiny shop is an Aladdin's Cave of plumbing parts and the guy behind the counter was determined that I wouldn't leave empty handed. He went out of his way to help me find just the right thing. Thank you so much. The shiny new chrome drain cover looks amazing and it was well worth the drive from north San Antonio to discover this neighborhood gem of a business. And, if you're looking to replace your hot water heater, they apparently have better prices and better quality units than any of the big box stores.

My mom called 1st Call Plumbing to check for a leakage at her home. She was recommended this company by a family friend. It was easy to make the appointment with Teresa and they came out the same day. Reno and Cory were very professional, wearing masks. They used a camera to check for leakage and determined the source of the leak. They didn't charge for their visit and recommended that we follow up with an appliance specialist. Thank you for your honest and efficient help!

outstanding and reliable!! Greg is passionate about his work and providing amazing customer service!

I had them run a jetter to unclog my sewer line at my home and they did a great job. They sent me a text when they were on their way and arrived on time.

Tator has handled 3 or 4 jobs for me including leak detection/pinpoint tests, sewage line repair and water line repair. Always on time, always do great work, always professional. Fair prices, friendly people on the phone. Highly recommended!

Great service, the plumbers were very attentive, knowledgeable and fast, and I was shocked when the bill came it was very inexpensive. I did call other competitors and they quoted me way higher than Harold's Plumbing did. I will continue to use this company for my plumbing. I'm not sure what those other peoples comments are so negative. I have not experienced anything like that so don't take everything you read so serious. A+ to Harold's plumbing!

Very impressed with the services I have received from this company. They're honest and only sell you what you need. No price gouging and quick turnaround on their work. Have used multiple times now and will continue to use in the future.
