Anthony did an excellent job with our pool repair. He was extremely knowledgeable and took the time to carefully explain everything. What stood out the most was that he never rushed the job—he spent extra time making sure everything was done right, yet didn’t charge us more for the additional work. That level of honesty and professionalism is rare these days. We’re very happy with the results and will definitely use his services again.

He gave me a quote to repair a small leak but never showed up for the work… tried to call him multiple times without any luck. In the meantime, my pool has turned green…

Onyx Custom Pools's reply

Hi there! Apologies for any delays you experienced. I had communicated with you once I was able to verify my account information and find your contact information again since my business phone was crushed and I had to get a new phone. It took me a day or two, however I did reach back out and it was unfortunately too late by the time I was able to access your contact info again. Hope you found the help you needed.

Anthony was a life saver! Our pool pump went out and we had it replaced by a different pool company. They did a really bad job and we needed it replaced again ASAP. With the scorching Texas heat, our pool was turning green without the pump. Anthony responded immediately and replaced the pump within 24 hours of my request on Thumbtack. Couldn’t be happier with his work - will definitely use him again!
