Guarantee Plumbing & AC, Inc. 4848 Whirlwind Drive, San Antonio, TX 78217

"They charged me $13000 to repair a drain line under the slab. Encountered issues recently, they don’t answer the phone or call me back. Will file complaints with the city of San Antonio and state soon . Strike team will not allow owner to register or pull permits again. Then aging, they didn’t even pull permits for my project. It’s been a long journey, now I have a hard time trusting any trade."

"They do not respond to emails and phone calls. They owe me for two years of maintenance service."

"Guarantee plumbing “cleared” a blockage for us in January only to find out that they only pushed back the blockage deeper into the drain line and now we cannot use our shower. We called to inform them but they are wanting to charge us anyway. This is a service they did not fix and I would not recommend this company to anyone. We spent over $800 for them to fix our issue only to cause another problem. Very disappointed with this company. Do not use them unless you want to waste your money."

"I would NOT recommend this company. This past year I bought a water heater maintenance agreement. The agreement stated they would check water pressure and flush the water heater twice during the year. They came out in December 2017 and August 2018. My water heater burst on November 27, 2018. I bought this agreement specifically to avoid this problem. The plumber who came to replace (NOT Guarantee Plumbing) showed us pictures of how the water heater had been leaking for quite some time. It was pretty bad. There was even duct work that wasn't placed correctly. They also told us our water pressure was high. The plumber from Guarantee Plumbing never told us there was a leak or even that there were problems with the pressure! What a waste of money! This same plumber came out because I was having problems with the shower head, it was making a loud noise when turned on. All he did was turn on the shower and said it needed to be replaced. I paid him for coming down and he lost the check. He didn't even give me a receipt. The office however did bill me and I had to put a stop payment on the check originally given to plumber. I am extremely upset at the incompetence. There is no pride in their work, the company obviously doesn't care who they hire. The reason we got the maintenance agreement was so that it was maintained properly. They failed us in that regard. Needless to say, I will not be using Guarantee Plumbing services ever again. The service agreement is a joke. I have lost confidence and trust in the company. By the way, the only reason they get one star is their receptionist who answers the phone. She is really good at her job. Deeply disappointed."

"Would not recommend this company. I needed my gas line checked so that I could pass a city inspection. They detected a leak and said they would have to go back to the shop to get the parts. They return about 45 minutes later and make the repair. The line is tested again and there is still a leak. They aren't finding the leak anywhere so they advise they will have to tear out holes in the kitchen and remove cabinets and countertops away from the wall. After doing so they still can't locate the leak. Then they tell me they can just replace the entire gas line instead for $2,600 since they cant find the leak. Knowing that this amount is absurd I just tell them to stop whatever they are doing. So they then give me a bill for $850, even though they were not able to solve my problem. I guess Guarantee Plumbing means that they Guarantee they won't fix your problem, but still charge you for it."
